How to Resize Images for Social Media in 2026: The Complete Size Guide

Every social media platform has different image size requirements. Here is the definitive guide to getting your images pixel-perfect for Instagram, Twitter, LinkedIn, YouTube, and more.

Getting your image dimensions wrong on social media is one of those small mistakes that makes a big difference. A cropped profile photo, a blurry Instagram post, a LinkedIn banner with the text cut off — these things make your content look amateur before anyone even reads it.
