Crop Image 4:5 (Portrait)

Automatically crop a photo to the 4:5 portrait ratio used by Instagram feed posts — free, instant.

How to crop an image to 4:5

Drop your photo into the box above and it's automatically center-cropped to a 4:5 portrait ratio, then offered for immediate download.

For example, a landscape or square photo can be cropped to this taller ratio here to take up more vertical space in a feed, which is exactly why many creators favor 4:5 over a plain square for feed posts.

Why 4:5 over a square

A 4:5 portrait crop takes up more vertical screen space than a 1:1 square in a mobile feed, which tends to draw more attention while scrolling. It's the tallest ratio Instagram's feed currently supports without cropping further.

Where a 4:5 crop is expected

4:5 is a taller-than-square portrait ratio that Instagram and several other feed-based apps use as their maximum-height post format, because it takes up more vertical space in a scrolling feed than a square photo would — one of the reasons portrait-style posts often get more attention than square ones on mobile.

This tool locks the crop selection to that 4:5 proportion automatically, so you can focus on framing the shot rather than calculating the right height-to-width relationship yourself. It's a good middle ground between a plain square crop and the much taller 9:16 ratio used for full-screen stories.

A practical middle ground

4:5 sits comfortably between a plain square and a very tall story-style crop, which makes it forgiving for a wide range of source photos — portraits, product shots and group photos all tend to crop into this ratio without losing too much of the original composition.

The crop box is locked to that proportion and updates live as you drag it, powered by the Canvas API running directly in your browser — you can readjust and re-check as many times as you like before exporting.

A quick check before exporting

Before finalizing, check that nothing important sits right at the very top or bottom of your selection — those areas are the most likely to get trimmed slightly further by a platform's own display logic, so leaving a small buffer around key details tends to give a more forgiving result.
