Convert an image to 4:5 ratio
A 4:5 ratio is slightly taller than square. Instagram allows feed posts up to 4:5, which is the tallest a regular post can be before the app forces a Stories-style crop — so it is the go-to choice when you want a portrait photo to take up more screen space in the feed than a 1:1 post would.

How to convert your image to 4:5 ratio
Upload your image using the tool above.
For a portrait photo, crop mode will trim a small amount from the top and bottom to hit the 4:5 ratio.
For a landscape photo you want to keep whole, switch to pad mode — it adds a neutral border above and below.

Why do you need to convert to 4:5 ratio?
Instagram caps its feed posts at 4:5 for portrait orientation — anything taller gets auto-cropped by the platform. Choosing 4:5 yourself means you control exactly what stays in frame, and your photo takes up roughly 20% more screen space than a square post, which generally translates to higher engagement.

Where this ratio is used
- Instagram feed posts shot in portrait orientation
- Pinterest pins (Pinterest's own recommended ratio)
- Fashion and product photography for vertical e-commerce listings
- Blog post featured images that need more vertical presence
Crop or pad — which should you use for this ratio?
4:5 sits close enough to square that cropping rarely removes much — it works well for almost any portrait-oriented photo. Use padding mainly for landscape photos you want to keep in full inside a 4:5 frame for a consistent feed grid, since cropping a wide landscape down to 4:5 trims away a large share of the original frame, not just a sliver.
How this ratio compares to a similar one
4:5 vs 9:16: choose 4:5 for the main Instagram feed grid where you want the photo visible without tapping anything; choose 9:16 specifically for Stories, Reels, and TikTok, which are full-screen vertical formats rather than feed posts.
Frequently asked questions
Why 4:5 and not 9:16 for Instagram feed posts?
9:16 is reserved for Stories and Reels. The feed itself caps portrait posts at 4:5 — uploading anything taller gets automatically cropped down to 4:5 by Instagram, so converting to 4:5 yourself gives you control over exactly what gets cropped.
Is 4:5 the same as Pinterest's recommended ratio?
Yes, Pinterest specifically recommends 2:3 to 4:5 for pins, with 1000×1500 px (2:3) being their most cited size — 4:5 is a slightly less tall, still well-supported alternative.
Should I crop or pad a landscape photo to 4:5?
Cropping works well if the subject is centered. If important details are near the left/right edges of a wide photo, padding (adding a border) preserves them instead of cutting them off.
Does Instagram crop my photo automatically if I upload something taller than 4:5?
Yes — uploading a photo taller than 4:5 (such as 9:16) to the regular feed gets center-cropped down to 4:5 by Instagram automatically, so converting it yourself first gives you control over exactly what's kept.
Is 4:5 a good ratio for product photography?
Yes, many fashion and lifestyle product photos use 4:5 because it shows more of a standing subject (a person, a tall product) than a square crop while still fitting cleanly in a feed-style grid.
