About social media image sizes
The six sizes and why they differ
Instagram posts use a 1080 px width with three aspect ratios — square (1080×1080), portrait (1080×1350) and landscape (1080×566). Stories and Reels are full-screen at 1080×1920. X and Threads render inline images best at 1600×900, and YouTube expects thumbnails at 1280×720. These are the dimensions each platform recommends for upload; platforms downscale for display but starting above their recommendation wastes bandwidth without adding sharpness.
What a safe zone is
Correct dimensions do not guarantee a usable post. Platforms draw their own interface over your image — a Story shows the account name at the top and a reply bar at the bottom, a YouTube thumbnail gets a duration badge in the bottom-right corner, and an Instagram profile grid crops posts to a smaller frame. The dashed outline marks the area that survives all of that. Keep text, faces and logos inside it. The overlay is preview-only and never appears in the downloaded file.
Why each size keeps its own framing
A square and a 9:16 vertical frame cannot show the same crop of one photo — something has to be cut, and which part depends on what the photo contains. Rather than guessing a mapping between sizes, this tool remembers the zoom and position you chose for each size separately. Adjust one and the others stay as you left them; switch back and your framing is still there.
FAQ
Common questions and answers about this topic.
What size is an Instagram Story?
1080×1920 pixels (9:16). Keep important content out of the top and bottom 250 pixels, where Instagram shows the account name and the reply bar.
What size is a YouTube thumbnail?
1280×720 pixels (16:9). Leave the bottom-right corner clear — YouTube draws the video duration badge there on every thumbnail.
What size should an image be for X or Threads?
1600×900 pixels (16:9) works well for both. Inline images are cropped toward that ratio in the timeline, so composing at it avoids surprises.
Why does my Instagram post look cropped in the profile grid?
The profile grid shows a narrower frame than the post itself, so portrait and especially landscape posts lose their edges there. The safe zone overlay marks what survives the crop — landscape posts have the widest margins for exactly this reason.
Do I need an account to use this?
No. Open the page, drop in an image and download — there is no sign-up, no install and no watermark.
Can I download all the sizes at once?
Yes. Tick more than one size and they are packed into a single ZIP, with each file named after its platform so you can tell them apart without opening them.
