2025 Social Media Size Guide

Square posts have been the default on Instagram since its launch, but they’re no longer the best option! With most users consuming content on their phones rather than desktops, vertical formats are now ideal for social media.

When posting static images, a portrait ratio takes up more screen space than a square, providing a distraction-free viewing experience. Plus, with Instagram’s January 2025 update, content previews on the Explore page and profile grid now display in a portrait format instead of square. This means your posts may be cropped, so be sure to keep key details within the safe zone.
