Why every platform needs a different size
Each social network shows images in its own frame. Instagram favors squares and tall 4:5 portraits in the feed, stories and reels fill a 9:16 phone screen, link previews on Facebook and LinkedIn are wide, and banners are extremely wide strips. If you upload a picture with the wrong shape, the platform crops it for you, often cutting off heads, products or text. Resizing to the exact shape first puts you in control of what is visible.
Common sizes
| Use | Pixels | Ratio |
|---|---|---|
| Instagram square post | 1080 × 1080 | 1:1 |
| Instagram portrait post | 1080 × 1350 | 4:5 |
| Stories, Reels, TikTok | 1080 × 1920 | 9:16 |
| Facebook and LinkedIn link image | 1200 × 630 / 1200 × 627 | about 1.91:1 |
| X in-feed image | 1600 × 900 | 16:9 |
| YouTube thumbnail | 1280 × 720 | 16:9 |
| YouTube channel banner | 2560 × 1440 | 16:9 |
| Pinterest standard pin | 1000 × 1500 | 2:3 |
Platforms change their layouts and recommendations from time to time, and the same image can be shown differently on phones and desktops. Treat these as reliable starting points, and check each network’s help pages if a size seems to have changed.
Crop, or fit with a background?
Crop to fill covers the whole frame, so nothing is left empty, but parts of the photo are cut away. It is best for photos with a clear subject and some space around it. Drag the image to keep the important part in view, and zoom in to tighten the composition.
Fit with a blurred background keeps the entire photo and fills the empty space with a soft, blurred copy of the same picture, the look you often see when a landscape photo is posted as a story. Fit with a solid color does the same with a plain color, which suits product shots, screenshots and brand graphics.
Getting the best quality
- Start from the largest original you have. Enlarging a small image cannot add detail, and the tool warns you when that happens.
- Use JPG at 85–90% for photos, and PNG for graphics with text, logos or transparency.
- Keep text and faces away from the edges of banners and profile photos, which are often cropped to circles or covered by buttons on some screens.
- Platforms re-compress uploads. Exporting at the exact recommended size usually gives the cleanest result after their processing.

Frequently asked questions
What size should an Instagram post be?
1080 × 1080 pixels for a square post or 1080 × 1350 for a portrait post, which takes up more of the feed. Stories and Reels use 1080 × 1920.
Are my photos uploaded to a server?
No. The image is resized on a canvas inside your browser and downloaded straight to your device. It never leaves your computer or phone.
How do I keep the whole photo without cropping?
Choose “Fit, blurred background” or “Fit, solid color”. The entire photo is placed in the frame and the empty space is filled.
Why does my resized image look blurry?
If the original is smaller than the target size, it has to be enlarged, which softens it. Use a larger original, or zoom out if you zoomed in while cropping.
Do these sizes ever change?
Yes. Social networks update their designs and recommendations, so double-check the platform’s current guidance if an upload looks off. You can always enter a custom size.
