What Social Media Image Sizer does
Resizes an image to the current standard size for nine specific placements, filling and cropping or fitting on a background.
These are placement-specific rather than platform-specific, because a single platform uses several. An Instagram feed post, a portrait post and a story are three different shapes, and using the wrong one is the most common reason a post looks wrong.
Placements covered
| Instagram post | 1080×1080 — square feed |
|---|---|
| Instagram portrait | 1080×1350 — the tallest the feed allows |
| Instagram / TikTok story | 1080×1920 — full-screen vertical |
| Facebook post | 1200×630 |
| X / Twitter post | 1600×900 · header 1500×500 |
| LinkedIn post | 1200×627 |
| YouTube thumbnail | 1280×720 |
| Pinterest pin | 1000×1500 — tall performs better here |
Detailed steps
- Drop the image in.
- Choose the exact placement, not just the platform.
- Use Fill & crop for photos, Fit where the whole image must survive.
- Keep important content away from the edges — interfaces overlay them.
Worth knowing
Stories and vertical video are the ones to be careful with. The top and bottom roughly 250 pixels sit under the platform’s own interface — profile name at the top, reply box and buttons at the bottom. Design as though the middle two-thirds is the only safe area.
Frequently Asked Questions
Why did my image get cropped after uploading?
The platform cropped it to its own aspect ratio, which is what happens whenever the uploaded shape does not match the placement. Sizing correctly first means you choose the crop rather than an algorithm choosing it for you.
Which Instagram size should I use?
Portrait 1080×1350 takes the most vertical space in the feed, which is why it tends to perform better than square. Square is safer if the composition needs it. Stories are a different shape entirely at 1080×1920.
Do these sizes go out of date?
They shift occasionally. These are the current widely-used dimensions, and the safest habit is to keep important content away from the edges so a change in crop costs you nothing.
Is one image enough for every platform?
No, and trying is why images get badly cropped. A square post and a full-screen story cannot be the same file. Export the sizes you actually need — it takes seconds each.
