Calculate resolution scaling for different display sizes
About Resolution Scaling
Resolution scaling determines how content is displayed when the output resolution differs from the source resolution. This calculator helps you understand scaling factors, pixel density changes, and how to maintain image quality across different display sizes.
Resolution Scaling Tips
- Integer Scaling: Scaling by whole numbers (2x, 3x) produces the sharpest results
- Aspect Ratio: Maintain aspect ratio to avoid distortion
- Upscaling: Higher quality algorithms (Lanczos) produce better results
- Downscaling: Generally produces better quality than upscaling
- Pixel Density: Consider PPI when scaling for different screen sizes
- Performance: Higher quality scaling requires more processing power
Common Resolution Standards and Scaling
| Resolution | Dimensions | Total Pixels | Common Uses | Scaling Factor |
|---|---|---|---|---|
| 480p (SD) | 854×480 | 409,920 | DVD, legacy content | 0.5x to 1080p |
| 720p (HD) | 1280×720 | 921,600 | HDTV, streaming | 0.67x to 1080p |
| 1080p (Full HD) | 1920×1080 | 2,073,600 | Standard HD, gaming | 1x (baseline) |
| 1440p (QHD) | 2560×1440 | 3,686,400 | Gaming, productivity | 1.33x from 1080p |
| 4K (UHD) | 3840×2160 | 8,294,400 | High-end displays | 2x from 1080p |
| 8K | 7680×4320 | 33,177,600 | Future displays | 4x from 1080p |
