Understanding 1080x1350 Resolution for Social Media

The term 1080x1350 size refers to an image dimension where the width is 1080 pixels and the height is 1350 pixels. This vertical image shape aligns perfectly with a 4:5 aspect ratio.

In digital media, pixels are the building blocks of your image, while the aspect ratio defines the proportional relationship between width and height. For 1080x1350, the calculation 1080 ÷ 1350 simplifies to 4:5, producing an image that’s taller than a square but shorter than a full story or reel format.

This format is widely optimized for modern social media feeds, especially on Instagram, where taller images often occupy more screen real estate without being cropped.

Why the 4:5 Aspect Ratio is Perfect for Instagram Feed

Instagram feed posts support vertical images up to a maximum aspect ratio of 4:5. Uploading an image taller than this will result in Instagram automatically cropping it. The 1080x1350 size uses the full vertical potential allowed, giving your post greater impact without losing important content.

By filling more vertical space in the feed, your post naturally stands out, increasing the likelihood that users will pause, look closer, and engage.
