Social Media Image Sizes: Complete Guide for All Platforms | Free

A No, that's a common myth. LinkedIn profile photos should be square — 400×400 pixels is the sweet spot. The platform crops them into a small circle anyway, so a horizontal image just gets chopped awkwardly. Stick with a headshot that fills the frame. Your banner is where you go horizontal.

A TikTok compresses videos aggressively, so starting with the wrong resolution makes things worse. Upload at 1080×1920 pixels (9:16) for best results. If your source is smaller, the platform stretches it and you lose sharpness. Stick to MP4 with H.264 encoding, keep bitrate above 8 Mbps. One more thing: upload from your phone, not a desktop. TikTok treats mobile uploads better.

A Pinterest prefers tall images. Use 1000×1500 pixels (2:3 ratio) for standard pins. Short or wide images get stretched to fit the feed, which kills quality. The platform also recommends keeping text within the center 600×900 pixel safe zone, or it might get cropped in search results. Upload PNG for sharpest results, not JPEG.

A You could, but the crop will be brutal. Twitter headers are 1500×500 pixels (3:1 ratio), while LinkedIn banners need 1128×191 pixels. That's almost 2.6 times shorter. Text or logos positioned at the top of your Twitter header will vanish entirely on LinkedIn. Create separate files for each platform. Quick tip: save text-heavy elements inside a 600×150 pixel safe zone for LinkedIn to avoid cutoffs.

A Facebook's algorithm scans images for text and flags anything over 20% coverage. You'll see a "low quality" warning or outright rejection. Keep your text under 10% of the total 1200×628 pixel canvas for ads. Use Facebook's Text Overlay Tool to preview before you submit. Stick to 100 characters or less in the image itself — put the rest in the headline or description.

A Nope — that'd be convenient, but it doesn't exist. Each platform has its own aspect ratio and pixel requirements. Instagram prefers square 1080x1080 for feed posts, Twitter loves 16:9 at 1200x675, and LinkedIn banners are that weird 1128x191 rectangle. Using one image everywhere means it'll get cropped, stretched, or blurry on at least three platforms. Our guide has the exact dimensions per platform so you don't have to guess.

A Yes, and here's the catch: Instagram carousels use the same 1:1, 4:5, or 16:9 ratios as single posts, but each card must be identical in dimensions. Mixing a 1080x1080 square with a 1080x1350 portrait causes ugly jumps when users swipe. Stick to one ratio per carousel. For portrait feeds, use 1080x1350 — it gives you 25% more screen space than square. Text placement matters too: keep key elements inside a 600x600 center zone for square carousels, or the crop might eat your headline in the grid view.

A Preview at actual size, not zoomed out. Most platforms compress images, so a file that looks sharp at 25% zoom will look soft at 100%. Open your image at 100% zoom and check for jagged edges. For logos or text-heavy graphics, zoom to 200% to spot pixelation early. Also, export as PNG for crisp text and graphics — JPEG adds artifacts that scream 'cheap.' Test your image on a phone and a desktop browser before scheduling. A quick side-by-side comparison catches 90% of issues.

A Uploading at 2x seems smart, but it backfires. Instagram caps display at 1080px wide, so a 2160px file just gets compressed harder, which introduces artifacts. Same story on Facebook — 2048px max, but 1200px is the sweet spot for feed posts. Twitter scales everything down to 1600px, and LinkedIn won't show more than 1100px. The only real exception is Pinterest, where 1000×1500 pins benefit from crisp PNG exports. Stick with platform-native sizes and optimize quality inside those bounds.

A Absolutely, and mixing them up is one of the most common mistakes. Thumbnails are 1280x720 pixels (16:9), while your channel banner needs 2560x1440 with a 1546x423 safe zone for text and logos. The tricky part: that banner gets cropped differently on TV, desktop, and mobile. Keep your channel name and upload schedule inside the center strip or mobile viewers won't see it at all.
