Fit vs. Crop

Crop

Best when the final canvas must be completely filled. ResizeDock preserves proportions and lets you choose which part of the image stays visible.

Fit

Best when you need to keep the entire original image. Empty space may be added around the image when the aspect ratios differ.

A balanced portrait ratio

4:5 is taller than a square without becoming as narrow as 9:16. It works well for portrait-focused graphics, product imagery and social layouts that favor a vertical composition.

Common uses for 4:5

  • Portrait social graphics
  • Product and lifestyle imagery
  • Vertical promotional cards
  • Any workflow that specifies a 4:5 image
