Understanding Proportions

The **Aspect Ratio** is the proportional relationship between an image’s width and its height. Our tool defaults to “Locked” mode to prevent distortion—ensuring your subject doesn’t look unnaturally stretched or squashed.

Common ratios include 16:9 (Widescreen TV), 1:1 (Instagram Square), and 4:5 (Portrait Social).

Optimal Dimensions by Platform

To avoid blurry images or awkward cropping, use these professional dimension standards:

Instagram Square: 1080 x 1080px
YouTube Thumbnail: 1280 x 720px
Facebook Cover: 820 x 312px
LinkedIn Banner: 1584 x 396px

Upscaling vs. Downscaling

Downscaling (making an image smaller) is generally safe and maintains high quality. However, Upscaling (making a small image larger) can lead to pixelation. Always start with the highest resolution source possible for the best results.
