PPI (pixels per inch) measures pixel density. Above 110 is generally considered good for desktop use at typical viewing distances. Stretched resolutions use a lower-than-native aspect ratio that stretches the image horizontally, making player models appear wider.

About this tool

  1. 1

    Enter resolution

    Input a display resolution (e.g., 1920x1080) or select from common preset resolutions.

  2. 2

    View calculations

    See the aspect ratio, total pixel count, PPI (if screen size is entered), and megapixel equivalent.

  3. 3

    Calculate stretched resolution

    Enter a non-native resolution to see how it stretches on your display - useful for competitive gaming.

  4. 4

    Compare resolutions

    Add multiple resolutions to see a visual comparison of their relative sizes.

  • For PPI calculation, enter your monitor's diagonal size in inches along with the resolution.
  • Stretched resolutions (e.g., 4:3 on a 16:9 monitor) make character models wider in FPS games - some players prefer this.
  • Common aspect ratios: 16:9 (standard), 21:9 (ultrawide), 16:10 (some laptops), 4:3 (legacy).
  • Aspect ratio calculation from any resolution
  • PPI/DPI calculation with monitor size input
  • Stretched resolution visualization showing distortion on your native display
  • Visual size comparison of multiple resolutions
  • Common resolution presets: 720p, 1080p, 1440p, 4K, 5K, 8K, and ultrawide variants
  • Determining the aspect ratio of an unknown display resolution
  • Calculating PPI to compare monitor pixel density when shopping for displays
  • Figuring out the best stretched resolution for competitive FPS gaming
  • Comparing resolution options when choosing between monitors or laptops
