Complete Guide to Social Media Image Sizes in 2026

Using the correct image dimensions for social media is crucial for making your content look professional and engaging. Wrong sizes lead to awkward cropping, blurry images, and lost engagement. This guide covers every major platform's image requirements for 2026.

Why Image Sizes Matter
