Image dimensions across major platforms shifted again in 2025-2026 as Instagram standardized on 4:5 portrait, TikTok pushed 9:16 deeper into Story-style feeds, and LinkedIn added carousel native posts with their own specs. Posting at the wrong size in 2026 is more costly than it used to be — feeds are denser, attention is shorter, and a poorly cropped thumbnail kills click-through before a viewer reads a word. This guide is the current size sheet for every major surface, refreshed against each platform's creator documentation as of April 2026.
For example, the recommended size for in-stream photos on X is 1600 x 900 pixels, while Facebook feed posts should be 1200 x 630 pixels. Using the correct image sizes ensures your visuals are displayed properly, avoiding any unintended cropping or pixelation. This can greatly enhance the viewer's experience and increase the likelihood of engagement.
Whether you're sharing on mobile or desktop, each social network has its own specifications. Instagram portrait images should be 1080 x 1350 pixels, while Facebook cover photos need to be 851 x 315 pixels. By adhering to these guidelines, you can ensure your social media presence remains consistent and visually appealing.
