4:5 Image Resizer: Perfect Portrait Format for Instagram

What is 4:5 Aspect Ratio?

The 4:5 aspect ratio is a portrait (vertical) format where the width is 4 units and the height is 5 units. This creates a slightly tall image that takes up more vertical space in feeds than square posts.

Instagram-Specific Considerations

4:5 on Instagram:

Larger than 1:1 squares in feed
Takes up more screen real estate
Scrolls slower (more view time)
Great for stopping scroll
Grid shows crop - full image in feed

Grid vs Feed:

Grid shows cropped/square version
Full 4:5 visible when opened
Plan for both views
Keep important elements in square safe zone

Common 4:5 Formatting Mistakes

Forgetting Grid Display

Instagram grid shows square crop of 4:5 images. Important elements should be visible in both views.

Using for Horizontal Content

Horizontal images cropped to 4:5 may cut off important elements. Better to use 1:1 or redesign.

Ignoring Extra Space

Not utilizing the additional vertical space defeats the purpose of using 4:5 instead of 1:1.

Wrong Content Choice

Not all content benefits from 4:5. Sometimes square (1:1) is more appropriate.
