Monitor Desk Depth Fit Calculator
The Monitor Desk Depth Fit Calculator checks whether a monitor will actually leave you enough room to sit back and view it comfortably on your desk. Enter your Desk Depth, your Monitor Stand Depth (or just the Screen Diagonal if you don't know the stand depth yet), and your Minimum Viewing Distance, and you'll get the Remaining Distance from the screen to where you'd sit, plus a clear fits-or-doesn't-fit verdict. Use the screen area calculator any time you need a fast, accurate figure without doing the arithmetic yourself.
Stand depth varies a lot by monitor model and is easy to get wrong — check your monitor's spec sheet for an exact figure if you have it. Leaving the field blank uses a rough estimate based on screen diagonal instead.
Ever wondered if that new monitor desk depth fit calculator result actually translates to a comfortable, healthy desk setup — or whether your current screen is quietly wrecking your posture and productivity? Whether you are planning a home office upgrade, choosing between a 34-inch ultrawide and dual 27 inch panels, or simply trying to confirm a new display will leave enough keyboard space, the fit result you see above tells you everything you need to know before you buy. Getting the viewing distance and desk depth right is not just about tidiness — it directly protects your eye health, prevents neck pain, and keeps your monitor configuration feeling spacious rather than cramped.
How to Use This Dual Monitor Desk Calculator to Check Your Desk Fit
Enter Your Desk Depth and Monitor Stand Depth
Start by measuring your actual desk depth — from the front edge of the work surface where your wrists rest to the back wall or back edge. Most standard desks run 24 to 30 inches deep. Enter that figure into the desk depth field, then add your display stand depth (the distance from the front foot of the stand to the rear of the panel body). A typical fixed base is 8 to 12 inches deep, while a mounting arm reduces that projection to as little as 2 to 4 inches behind the pivot point. If you plan to mount panels on an articulating arm, enter the arm's reach projection rather than the stand depth. The tool supports both inches and centimeters — use the unit toggle to switch between them instantly so you can cross-reference furniture specs from any retailer. This is one of the most useful steps in desk organization and office planning before you commit to a purchase. The diagonal to dimensions converter online handles the conversion entirely client-side, so nothing you enter is ever transmitted.
Read Your Remaining Desk Space and Fit Verdict
Once you enter your desk dimensions and panel diagonal size, the calculator returns three key outputs: usable desk depth remaining (the space left over for your keyboard, mouse area, and accessories after the display stand or arm consumes its share), the recommended viewing distance based on your display size and resolution, and a fit verdict — tight, comfortable, or spacious. A tight verdict means your current arrangement may push the panel too close for comfortable viewing distance; spacious means you have room to push the screen back for extra distance or to add a keyboard tray without crowding the display. The tool also flags any possible issue with desk depth consumed versus minimum recommended depth for your panel size.
Front View vs Top-Down View for Desk Planning
The front view shows how your panels will appear from your seating position — this is where you see physical width compression in action. When a secondary display is angled inward, its visible width shrinks because the apparent width equals the panel's physical width multiplied by the cosine of the inward angle. The top-down view reveals the desk depth map — how much of the work surface depth the stands or arms consume, where the displays sit relative to the back wall, and how much depth remains for keyboard space and mouse area. Toggle between the two views to understand both the visual experience and the desk footprint before committing to a layout.
Understanding Your Results: What Each Measurement Tells You With This Desk Calculator
Viewing Distance and Why It Varies by Resolution
Your viewing distance is measured from your nose bridge (not the back of your skull, and not the front edge of the desk) to the actual panel surface — not the frame. The calculator derives this from your desk depth minus the stand depth, giving you the distance from your sitting position to the display. This number matters enormously: occupational health research consistently links incorrect viewing distance to computer-vision syndrome, digital eye fatigue, tension headaches, and dry eyes. The critical insight is that resolution changes the comfortable viewing distance range significantly. A 24-inch 1080p panel has a pixel density of roughly 91 PPI, meaning individual pixels become visible as fuzz at distances under 22 inches. A 27-inch 4K panel runs at approximately 163.18 PPI — you can comfortably sit 4 to 6 inches closer without visible pixelation. A standard 1080p monitor setup needs more distance than a same-size 4K panel. The tool accounts for pixel density so your fit recommendation reflects your actual resolution, not just the diagonal measurement. Run the screen megapixel calculator online to double-check a result before you rely on it for something important.
Screen Height and Eye Level Positioning
Correct panel height places the top of the display at or just below your eye level when you are seated with proper posture. This puts the center of the screen roughly 4 to 6 inches below eye level, which aligns with the natural resting angle of your eye muscles and helps prevent the forward lean that compresses your cervical spine. If the display is too low — a common problem with laptop panels used as primary displays or with a stock stand on a compact desk — your head tilts forward by 15 to 30 degrees, effectively doubling the load on your neck and leading to wfh neck pain and upper-back tightness. If you use a height-adjustable desk, remember that your eye level difference between sitting and standing positions can be 4 to 6 inches; an adjustable mounting arm is the most practical way to handle that shift without compromising your ergonomic workspace in either position.
Tilt Angle and Its Effect on Ergonomic Positioning
The tilt angle field tells you how far your panel should lean backward to place the display surface roughly perpendicular to your line of sight. A backward tilt of 10 to 20 degrees is the comfort target: it reduces glare from overhead light, minimizes the neck angle required to read the bottom edge of the panel, and keeps your eye muscles in their least strained convergence position. Forward tilt — pointing the top of the screen toward you — is one of the most common positioning mistakes; it catches ambient light as glare and forces a slight downward head tilt to read the lower portion of the display. Most stock stands offer only 5–10 degrees of backward tilt, which is insufficient for taller users or anyone with a deeper desk. A quality mounting arm gives you continuous tilt adjustment without tools, which is especially valuable on a standing desk where your viewing position changes throughout the day.
Quick Reference: Monitor Desk Calculator for Desk Depth by Screen Size
Standard Single Monitor Depth Needs
The table below gives you minimum and recommended desk depths for the most common panel sizes across 1080p, 1440p, and 4K resolutions. Use this as a quick reference alongside the desk buying calculator above — following these desk size recommendations will confirm your surface can physically accommodate the screen you are considering before purchasing. This is practical desk buying guidance for anyone planning a new desk setup.
| Monitor Size | Resolution | Min. Desk Depth | Recommended Desk Depth | Comfortable Viewing Distance |
|---|---|---|---|---|
| 24 inch | 1080p | 20 in (51 cm) | 24 in (61 cm) | 22–26 in (56–66 cm) |
| 24 inch | 1440p / 4K | 18 in (46 cm) | 22 in (56 cm) | 18–22 in (46–56 cm) |
| 27 inch | 1080p | 24 in (61 cm) | 30 in (76 cm) | 28–32 in (71–81 cm) |
| 27 inch | 1440p | 22 in (56 cm) | 28 in (71 cm) | 24–28 in (61–71 cm) |
| 27 inch | 4K | 20 in (51 cm) | 26 in (66 cm) | 22–26 in (56–66 cm) |
| 32 inch | 1440p | 26 in (66 cm) | 30 in (76 cm) | 28–34 in (71–86 cm) |
| 32 inch | 4K | 24 in (61 cm) | 28 in (71 cm) | 26–30 in (66–76 cm) |
| 34 in Ultrawide | 1440p (21:9) | 26 in (66 cm) | 32 in (81 cm) | 30–36 in (76–91 cm) |
| 49 in Super-UW | 1440p (32:9) | 28 in (71 cm) | 36 in (91 cm) | 32–40 in (81–102 cm) |
Two patterns stand out in these figures. First, a 4K panel can sit 4 to 6 inches closer than the same diagonal at 1080p because higher pixel density means sharper text at shorter distances — the 27-inch 4K display running at 163.18 PPI versus a 1080p panel at 108.8 PPI is the clearest example. Second, wide-format panels demand extra viewing distance because the outer edges of the screen sit further from your eyes than the center; at a larger measured diagonal, you need at least 32 inches of distance so a moderate head turn is sufficient to scan the full width without neck rotation.
Ultrawide and Super-Ultrawide Monitor Desk Depth Considerations
A 34-inch ultrawide in 21:9 format runs roughly 32 inches (81 cm) wide and 14 inches (36 cm) tall, with a stand that can consume 10 to 12 inches of desk depth. On a 24-inch-deep desk, that leaves only 12 to 14 inches for keyboard depth and mouse space — workable but snug. The 49-inch super ultrawide (32:9 format, like the Samsung Odyssey G9) is approximately 47 inches wide; its stock base alone is 12 to 14 inches deep, leaving almost no keyboard screen real estate on a shallow 24-inch desk. The minimum desk depth for a 49-inch super ultrawide on a standard upright stand is approximately 28 inches, and most users with this panel type switch to a heavy-duty mounting arm or wall bracket to reclaim the surface. A curved wide-format panel helps by keeping the outer edges at a more consistent distance from your eyes, reducing the need for head rotation at extreme widths.
Dual Monitor Desk Calculator: Side-by-Side Layout Depth
Two panels in a dual monitor side-by-side arrangement share the same desk depth as a single panel — the depth constraint is per-screen, not cumulative — but the desk width requirement doubles. A standard 24-inch monitor (a popular 1080p monitor choice) measures approximately 21 inches wide, while a typical 27-inch monitor measures approximately 24 inches (61 cm) wide. Two 27-inch panels placed flat side by side consume 48 inches (122 cm) of desk width — close to the limit of a standard surface. Angling each secondary panel inward at 15 degrees reduces the combined apparent width to roughly 46.4 inches, and at an inward angle of roughly one-third of a right angle the combined footprint shrinks to about 44.8 inches (114 cm), making the layout genuinely comfortable on a standard-width surface. For the dual panel arrangement, the mounting depth matters individually: each screen still needs 8 to 12 inches of stand depth unless arms are used, so the per-screen depth constraint applies to both panels simultaneously from your seating position. Use the dual unit toggle in the tool to verify both width and depth in your preferred measurement system.
Why Desk Depth Affects More Than Fit — A Monitor Buying Fit Calculator Perspective
How Sitting Too Close Causes Eye Strain and Musculoskeletal Problems
When the panel is too close to your eyes, your eye muscles lock into a sustained convergence position — the same fatigue you would experience reading a book held six inches from your face for eight hours. This is the clinical mechanism behind computer-vision syndrome and visual fatigue: the ocular muscles cannot relax, iris dilation becomes erratic as you glance between the bright panel and darker surroundings, and fatigue accumulates into tension headaches and dry eyes by mid-afternoon. The 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds) helps break this cycle, but it cannot compensate for a panel that is chronically too close. Luminance level also plays a role: when screen brightness far exceeds ambient light levels, the contrast forces your eyes to work harder. Match panel luminance to room ambient light — a white paper brightness test (hold a sheet of paper beside the screen and adjust until both appear equally bright) is a quick calibration method. Similarly, bias lighting behind the panel reduces the perceived contrast between the bright surface and the dark wall, which eases visual wellbeing during long sessions, especially in the evening when night mode should also be activated.
Practical Layout Examples for Common Desk Sizes
Understanding how your desk dimensions interact with panel footprint is where this planning tool earns its value. Here are three worked examples covering the most common scenarios:
Example 1 — 48-inch wide desk (24-inch deep) with a single 27-inch monitor on a fixed base:
- The 27-inch monitor has a physical width of approximately 23.5 inches and a stand base depth of roughly 10 inches.
- Desk depth consumed by stand: 10 inches. Remaining depth for keyboard: 14 inches — adequate for a standard keyboard but tight for a keyboard tray and wrist rest combined.
- Your seating position (eyes roughly 4 inches behind the front desk edge) adds to the viewing distance: 24 in desk depth − 10 in stand depth = 14 in from front edge to panel face + ~4 in from desk edge to eyes ≈ 18 inches of viewing distance. That is below the 1080p recommended minimum of 28 inches — a tight fit result that flags as a possible issue for a 1080p panel but is acceptable for a 1440p or 4K display.
- Verdict: Tight for 1080p; comfortable for 1440p/4K. A mounting arm would push the panel to the back wall, recovering 4 to 6 inches of viewing distance and freeing keyboard space.
Example 2 — 60-inch wide desk (30-inch deep) with a 34-inch ultrawide primary + 27-inch secondary angled at roughly one-third of a right angle:
- The wide-format stand consumes approximately 12 inches of desk depth. The secondary panel arm (if used) adds roughly 4 inches of depth projection.
- From your seated position, the primary face sits approximately 30 − 12 + 4 (eye-to-desk-edge) = 22 inches from your eyes — within the comfortable 20 to 32 inch range for a 1440p wide-format panel.
- The 27-inch secondary angled inward has a visible width of 24 × cos(30°) ≈ 20.8 inches. Combined desk width: 32 in (wide-format) + 20.8 in (secondary panel) + 2 in (frame gap) ≈ 54.8 inches — fits the surface with room to spare.
- Remaining depth after stands: 30 − 12 = 18 inches for keyboard and mouse. Verdict: Comfortable. No major issue flagged. Ideal for a power-user hybrid or mixed work and creative development setup.
Example 3 — 55-inch desk (24-inch deep), switching from a fixed base to a mounting arm on a 32-inch display:
- Original fixed base depth: 11 inches. Viewing distance from seated position: 24 − 11 + 4 = 17 inches — panel too close at any resolution. A possible issue for visual fatigue and neck angle.
- With a mounting arm projecting 3 inches from the wall: the panel face now sits approximately 24 − 3 + 4 = 25 inches from the eyes — squarely in the 24 to 30 inch comfortable range for a large 4K display.
- Desk depth reclaimed: 11 − 3 = 8 inches of surface recovered for keyboard depth and accessories space.
- Verdict: Spacious upgrade. The mounting arm resolves both the viewing distance problem and the keyboard real estate constraint in one move.
Multi-Monitor Angles and Physical Width Compression
When you angle a secondary panel inward, its physical width appears narrower from your seated position — a direct consequence of the cosine of angle relationship. A 27-inch panel (23.5 in wide) angled inward at 15 degrees has an apparent width of 23.5 × cos(15°) ≈ 22.7 inches. Tilted further to about one-third of a right angle, that shrinks to 23.5 × cos(30°) ≈ 20.3 inches. This is why angled panels in a dual layout fit desks that would otherwise be too narrow when screens are flat side-by-side. The top-down depth view in the tool shows this compression visually, including curvature for curved or wide-format panels. For a triple layout (such as flight sim or racing setups), each secondary panel angled inward at roughly one-third of a right angle can reduce total combined width by 6 to 10 inches compared to a flat arrangement — the difference between fitting a 72-inch desk comfortably and requiring a wider surface.
The inward angle also affects head rotation demands. Each secondary display set at 15 to 20 degrees inward means a simple head turn (not neck rotation) reaches the screen edge. At a steeper inward angle, head turns are slightly larger but still within the comfortable threshold. Panels placed flat and far apart force neck rotation and can cause neck strain during long multitasking sessions. The seam between a primary panel and a secondary panel should align with the center of your nose bridge when both are used equally; if one is clearly dominant, place that screen directly front-facing and angle the other to the side.
Fixed Stand vs. Monitor Arm: What the Monitor Buying Calculator Reveals About Depth Reclaim
How Much Depth a Monitor Arm Reclaims
A fixed base on a typical 27-inch monitor or larger panel occupies 8 to 12 inches of desk depth from the front foot to the rear of the screen. A monitor arm — whether a clamp mount securing to the desk edge or a grommet mount passing through a hole in the surface — replaces the stand base with a pivot arm whose reach from the desk edge is adjustable. Most quality arms position the screen 2 to 4 inches forward from the wall (or desk back edge), reclaiming 6 to 10 inches of surface compared to a fixed base. That recovered depth translates directly into viewing distance: push the panel further back and you gain inches from eyes to screen without moving your chair. On a compact or shallow surface, this is often the only practical way to achieve the recommended viewing distance for a 27-inch monitor running at 1080p or for larger displays, making it one of the most impactful desk size recommendations you can follow.
Before you buy mounting arms, verify three things: the VESA pattern on the back of your panel (75×75 mm or 100×100 mm are the most common), the arm's weight rating versus your panel's actual weight (a large 32-inch panel can weigh 12 to 18 lbs — use a gas spring arm rated above that load capacity to avoid sagging), and whether a desk clamp will grip your desk edge profile or if a grommet mount is needed for a thick or beveled edge. A gas spring arm provides tool-free adjustment and is essential for height-adjustable desk users who need to shift panel height as eye level changes between sitting and standing positions.
Essential Features to Look For in a Monitor Arm
Key monitor arm selection criteria
- VESA compatibility: Confirm your panel's vesa pattern (75×75 or 100×100 mm) matches the arm's mounting plate before purchasing.
- Weight rating: Choose an arm rated at least 20% above your panel's actual weight. Heavy-duty arm models (25 lb+ rated) cover most large and wide-format panels.
- Gas spring vs. mechanical: A gas spring arm offers smooth, tools-free adjustment — critical for a standing desk environment. Mechanical arms with allen key adjustment are cheaper but less convenient for frequent repositioning.
- Clamp vs. grommet mount: A desk clamp attaches to the desk edge and suits most work surfaces. A grommet mount threads through a pre-drilled hole and is more stable for heavier panels or thicker surfaces.
- Reach and articulation: Confirm the arm's maximum reach extends far enough to push the panel to the back wall clearance zone while still allowing it to swing forward for wire routing access or cleaning.
- Wire routing: Integrated cable guides keep DisplayPort, HDMI, and USB-C cables routed neatly through the arm, reducing desk clutter and preserving a clean placement aesthetic. Good wire routing is one key aspect of effective cable management.
When a fixed base is actually fine: if your desk depth is 30 inches or more and the resulting viewing distance lands within the comfortable range for your panel size at your chosen resolution, the stock stand does its job without needing replacement. Deeper surfaces in a spacious dedicated workspace often have no major issue with fixed bases on panels up to 32 inch diagonal size. The monitor desk depth fit calculator above will give you a clear spacious verdict in these cases — use that as your signal to leave the arrangement as it is and invest the arm budget elsewhere.
Popular Desk Layouts and Pass/Fail Fit Verdicts — Tested With Our Monitor Desk Depth Fit Calculator
Use the following quick-reference table to check whether your desk width and panel combination clears the minimum width threshold before running the full depth analysis above. These figures assume panels on fixed bases with a 2-inch frame gap between adjacent screens and a 5-inch edge buffer on each side of the surface.
| Desk Width | Monitor Configuration | Combined Monitor Width | Min. Width Needed | Fit Verdict |
|---|---|---|---|---|
| 48-inch desk | Single 27-inch 1440p | 23.5 in | 28 in | ✅ Spacious |
| 48-inch desk | Dual 24-inch 1080p (flat) | 41.8 in | 46 in | ⚠️ Tight (angle monitors inward) |
| 48-inch desk | Dual 27-inch (angled 30°) | 40.6 in | 45 in | ✅ Comfortable |
| 55-inch desk | Single 34-inch ultrawide | 32.1 in | 37 in | ✅ Spacious |
| 55-inch desk | Dual 27-inch + 27-inch (flat) | 47.0 in | 52 in | ⚠️ Tight |
| 60-inch desk | 34-inch UW + 27-inch (30° angle) | 52.4 in | 57 in | ✅ Comfortable |
| 60-inch desk | Dual 32-inch 4K (angled 15°) | 55.4 in | 60 in | ⚠️ Tight — arm recommended |
| 72-inch desk | 49-inch super ultrawide | 46.9 in | 52 in | ✅ Comfortable (depth is primary concern) |
| 48-inch desk | 49-inch super ultrawide | 46.9 in | 52 in | ❌ No fit — monitor wider than desk |
For the 49-inch super ultrawide on a standard surface, the minimum desk width is almost exactly the panel width itself (a 49-inch 32:9 super-wide panel measures about 47 inches wide), leaving less than an inch of overhang clearance. More critically, the base on these panels is 12 to 14 inches deep — on a 24-inch deep surface, that leaves only 10 to 12 inches of depth for your keyboard, mouse, and any other peripherals. This is the single scenario where wall mounting or a purpose-built heavy-duty mounting arm is not optional but necessary for a functional ergonomic setup. Most users who mount these to an arm report that the desk canvas that opens up — keyboard space, a tablet in landscape mode, and a notepad — transforms the usability of the entire surface.
Buying Guidance: Using This Planning Tool and Screen Diagnostics Checker Before You Commit
The most valuable moment to use a monitor buying calculator is before purchasing — not after the box arrives. Run three scenarios through the tool as part of your buying process: the panel you are considering on your current desk with the existing fixed base, the same panel with a mounting arm, and the next size up if you are on the fence between screen sizes or between a wide-format panel and a super-wide. Comparing those three fit results side by side gives you a clear, data-backed recommendation rather than a guess.
The resolution field matters as much as the diagonal. A 24-inch 1080p panel at a short 18-inch viewing distance will appear sharp because that pixel density at that size gives approximately 91 PPI — borderline for comfortable text at close range. Moving to a 27-inch 1440p panel at 108.8 PPI at the same distance gives noticeably sharper text. Stepping up to a 27-inch 4K at 163.18 PPI means sharp text even at 20 inches. The tool's pixel density output directly reflects your use case: tasks like document review and software development reward higher PPI; competitive gaming at lower resolution may actually be the correct choice since the faster refresh rate matters more than pixel count at typical gaming-rig distances. Consider your primary use — visual design work, programming, competitive play, or mixed work — when interpreting the fit result, since the ideal height, distance, and resolution trade-off differ across those use cases.
Connectivity also factors into your planning. Confirm your GPU or laptop dock supports the connection standard your new panel requires — a 4K monitor at 144 Hz needs DisplayPort 1.4 or HDMI 2.1; a USB-C hub may be needed to drive an external panel from a modern thin laptop while simultaneously charging. Check the cable guide for your target refresh rate before finalising your hardware selection.
Finally, consider the broader comfort ecosystem around your panel. An ergonomic chair with correct seat height, a slide-out keyboard shelf that keeps your wrists neutral, and a sit-stand desk that lets you alternate between seated posture and a standing position all work together with the correct panel placement to create a genuinely healthier workspace. Good ergonomics at the screen level addresses visual fatigue and neck strain; sound ergonomics at the chair and desk height level protects your lower back and promotes wellness across your productive hours.

Frequently Asked Questions
- What monitor size is best for a normal desk?
- For a standard desk with 24–28 inches of depth, a 24–27 inch monitor is generally ideal. A 27-inch monitor at 1440p offers excellent sharpness and fits comfortably at typical arm-length viewing distances. Larger monitors like 32 inches or ultrawide screens benefit from a deeper desk (30 inches or more) or a monitor arm to push the screen back.
- How far should I sit from my monitor?
- The general ergonomic guideline is to sit approximately an arm's length away from your screen — typically 20 to 40 inches depending on monitor size. As a rule of thumb, multiply the diagonal screen size in inches by 1.0–1.5 to get a comfortable viewing distance range. For a 27-inch monitor, that's roughly 27–40 inches from your eyes.
- What is the ideal viewing distance for a 27-inch or 32-inch monitor?
- For a 27-inch monitor, the recommended viewing distance is 27–40 inches (about 70–100 cm). For a 32-inch monitor, aim for 32–48 inches. At these distances, your eyes can comfortably take in the full screen without straining. Higher resolutions like 1440p or 4K allow you to sit slightly closer while still seeing sharp, comfortable text.
- Does monitor resolution affect the recommended viewing distance?
- Yes — resolution directly affects how sharp the image appears at a given distance. A 4K monitor can be viewed up to 30% closer than a 1080p display of the same size before individual pixels become visible. PPI (pixels per inch) is the key metric: 90–110 PPI at your viewing distance is a comfortable target for most work tasks.
- How much desk depth do I need behind my monitors?
- You need enough depth to accommodate the monitor stand footprint (typically 6–10 inches) plus your desired viewing distance. For a 27-inch monitor at a 28-inch viewing distance, you'd ideally have at least 30–36 inches of total desk depth. A monitor arm can reclaim stand space and give you more flexibility on shallower desks.
- What is the ideal distance for an ultrawide monitor?
- Ultrawide monitors (21:9 or wider) are physically wider than standard screens, so the horizontal field of view becomes more important. Most ergonomists recommend a viewing distance of 1.0 to 1.5× the screen's diagonal for ultrawides. At a 34-inch ultrawide, aim for 34–50 inches of eye-to-screen distance to avoid excessive head turning.
- Should I use a monitor arm or a standard stand?
- A monitor arm is ideal if your desk is shallow (under 24 inches deep), you want to reclaim surface space, or you need to quickly adjust the height and distance of your screen. Fixed stands take up 6–10 inches of desk depth and lock you into one position. For ergonomics on compact desks, a monitor arm is almost always the better choice.
- How do I prevent eye strain from my monitor?
- Beyond correct viewing distance, ensure your monitor's top edge is at or just below eye level, apply the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds), enable night mode or blue light filtering in the evening, and make sure ambient room lighting matches screen brightness. Correct distance alone eliminates a large share of digital eye strain.
