Every Social Media Image Size That Actually Matters in 2026

Almost every "wrong size" problem comes from the same place: you design something beautiful, upload it, and the platform crops the part you cared about. It is not your design sense — it is that each platform crops differently, and most design tools hand you a canvas without telling you where the crop lands.

The sizes, at a glance

The part nobody tells you: safe zones

A header is not a flat rectangle. On X, your profile picture sits over the bottom-left corner, and the platform crops the top and bottom differently on mobile versus desktop. So the usable area is smaller than the canvas you were given.

• ✦Keep important text in the middle vertical third — that band survives every crop.
• ✦Leave the bottom-left corner empty on X headers. Your avatar covers it.
• ✦Do not put your logo near any edge; assume 10% of each side can disappear.
• ✦Test in dark mode. Transparent PNGs that look great on white can vanish on a dark profile.

Where the popular tools land

Canva and Adobe Express are genuinely excellent — huge template libraries, collaboration, brand kits. If you are producing a full campaign, they earn their keep. The friction shows up on the small, repetitive jobs: sign in, find the right preset, dodge the Pro-only assets, export, then discover your text sits under your avatar anyway.

The honest split: reach for a template library when you want inspiration and polish. Reach for a Discord banner maker or X header maker when you know what you want and you need it correct, now, without an account. Ours draw the avatar and mobile-crop guides directly on the preview, so you can see the danger zones while you design.

Stickers are their own beast

Discord stickers are the fiddliest format on this list, because three constraints fight each other: exactly 320×320, animated, and under 512 KB. Animated PNG is the format Discord wants, and naive APNG exports routinely land at 2–5 MB.

1. 1Start from a short clip — under about three seconds. Length costs more than resolution here.
2. 2Crop to a square before you do anything else, so you are not paying bytes for pixels you will discard.
3. 3Cut the frame rate. Going from 30 fps to 15 fps roughly halves the file with little visible loss.
4. 4Reduce the color palette. Flat, bold art survives quantization far better than gradients or film footage.
5. 5Name the file with a .png extension — Discord rejects .apng even when the contents are valid.

Our Discord Sticker Maker automates that whole loop: it squares and resizes to 320×320, then steps frame rate and palette down until the file fits under 512 KB, and tells you the final size before you download.

If your source image is too small or too heavy

Two failure modes come up constantly. If your artwork is lower resolution than the target, upscaling it first beats letting the platform stretch it — try the AI Image Upscaler. If your export blows past a file-size cap, run it through the Image Compressor, which lets you target a specific size, or switch formats with the Image Converter. WebP and AVIF are dramatically smaller than PNG when the platform accepts them.
