Calculate Resolution Scaling for Images and Video

Our resolution scale calculator helps you determine output dimensions when scaling images or video by a specific percentage or factor. Whether you're downsizing 4K footage for web delivery or upscaling content for larger displays, accurate scaling calculations ensure proper aspect ratio preservation.

Resolution scaling is essential for video editing, image processing, and content optimization. Understanding how scaling affects pixel counts helps you choose appropriate export settings and predict file sizes.

Understanding Different Scaling Methods

Downscaling (Reducing Resolution)

Downscaling reduces pixel dimensions, typically improving perceived sharpness as more source pixels are sampled into fewer output pixels. A 4K video downscaled to 1080p often appears sharper than native 1080p footage due to this supersampling effect.

Upscaling (Increasing Resolution)

Upscaling increases resolution by interpolating new pixels between existing ones. Traditional upscaling can appear soft, but modern AI upscaling algorithms can intelligently add detail, making upscaled content look significantly sharper than simple interpolation.

Common Scaling Ratios and Use Cases

Scaling by 50% reduces dimensions by half (4K to 1080p), while 200% doubles them. Clean scaling factors like 50%, 100%, 150%, and 200% often produce better results than arbitrary percentages because pixels align more evenly.

For display scaling in Windows and macOS, common settings include 125%, 150%, and 200%. These scaling factors make text and UI elements larger on high-DPI screens while maintaining sharpness through integer or near-integer pixel mapping.
