4 5 Ratio Image Size Guide for Social Media Platforms

Understanding the 4:5 Aspect Ratio Image Size

The 4:5 ratio image size is an aspect ratio where the width is four units and the height is five units. This vertical orientation is popular on major social media platforms because it captures more vertical space in the feed, creating a larger visual footprint without awkward cropping.

Using the correct aspect ratio is crucial because it determines how much of the screen your image occupies, directly influencing visibility, engagement, and retention. A well-prepared vertical 4:5 image usually stands taller than a square post, giving your content a stronger presence.
