Social media image size guide 2025
Complete 2025 guide to image dimensions for all 11 platforms — profile, cover, post, story, ad.
about the social media image size guide 2025
Every platform crops, compresses, or letterboxes images that don't match its expected dimensions — and a profile banner that looks perfect on desktop can lose its text behind the avatar on mobile. Keeping track of the correct sizes across Instagram, Facebook, X, LinkedIn, TikTok, YouTube, Pinterest, and the rest is a moving target because platforms revise their specs regularly.
The dimensions that matter most in 2025: Instagram feed posts perform best at 1080x1350 (4:5), Stories and Reels at 1080x1920 (9:16), X in-stream images at 1600x900 with a 1500x500 header, LinkedIn shared images at 1200x627 with a 1584x396 cover, Facebook link images at 1200x630, YouTube thumbnails at 1280x720, and Pinterest pins at 1000x1500 (2:3). Uploading at exactly these sizes — or larger at the same aspect ratio — avoids blur from upscaling and surprise crops.
Use the guide to look up profile, cover, post, story, and ad dimensions for all 11 major platforms in one place, updated for 2025. Once your visuals are exported at the right sizes, attach them to posts in PostAI and schedule the whole batch across platforms in a single pass.
frequently asked questions
What is the best image size for an Instagram post in 2025?
1080x1350 pixels (4:5 portrait) for feed posts — it occupies the most screen space in the feed. Squares at 1080x1080 still work, and Stories and Reels should be 1080x1920 (9:16 vertical).
What size should a Facebook cover photo be?
Upload at 820x312 pixels for pages. Note that mobile displays a narrower 640x360 crop, so keep logos and text in the central safe zone that survives both crops.
Can I use one image size across all social platforms?
A 1080x1080 square is the safest single compromise — every major feed accepts it without harsh cropping. But you'll leave performance on the table: vertical 4:5 or 9:16 formats get more screen space on Instagram and TikTok, while X and LinkedIn favor landscape 16:9 and 1.91:1.
