4:5 Aspect Ratio
4:5 is a portrait (taller than wide) ratio that takes up the maximum vertical space allowed by Instagram's feed — giving your image more screen real estate than a square or landscape post. At a ratio of 0.8:1, it is slightly wider than a 9:16 phone screen, making it ideal for portraits, product shots, and editorial photography.

Frequently Asked Questions
Why use 4:5 instead of 9:16 for Instagram posts?+
Instagram crops 9:16 images for the feed to 4:5 (the maximum portrait ratio allowed for feed posts). If you use 4:5, you get the tallest feed image allowed without losing any content to cropping. 9:16 is for Stories and Reels only.
What are the pixel dimensions for 4:5 Instagram?+
The recommended size is 1080×1350 pixels. This is the maximum portrait size Instagram allows for feed posts and displays sharply on all devices.
Does 4:5 get more reach on Instagram?+
A 4:5 post takes up more vertical space in the feed than a 1:1 square or 1.91:1 landscape post, which can help capture more attention as users scroll. Many creators report higher engagement rates with portrait posts, though this is content-dependent.
