Image Resize Calculator
Work out scaled image dimensions and percentages.
Decide the numbers before you open your image editor. Scale by a percentage or set a target width or height, and this calculator returns the matching dimensions so nothing ends up cropped, squashed or guessed.
Lighter images, faster pages
- Serve images at the size they actually display — oversized files are one of the most common causes of slow pages.
- Work out crisp
@2xdimensions for high-density retina screens. - Keep the proportions locked so every export stays true to the original.
