Updated October 22, 2026
A picture of the wrong shape gets cropped by the platform in ways you did not choose. These are the commonly recommended sizes, and how to make your pictures fit them.
Recommended sizes
Platforms change their layouts from time to time, so treat these as a reliable starting point and check the platform's help page for anything important.
| Where | Size in pixels | Shape |

| Instagram post (square) | 1080 × 1080 | 1:1 |
| Instagram post (portrait) | 1080 × 1350 | 4:5 |
| Instagram story or reel | 1080 × 1920 | 9:16 |

| X (Twitter) post picture | 1200 × 675 | 16:9 |
| LinkedIn post picture | 1200 × 627 | About 1.91:1 |
| YouTube thumbnail | 1280 × 720 | 16:9 |

How to get exactly that size
- Open the Resize Image tool and press a quick size, such as Instagram post or YouTube thumbnail.
- These use Fill, which cuts the picture from the middle to the exact shape, so nothing is stretched.
- To choose which part to keep, use the Crop Image tool and pick a shape such as 1:1 or 16:9, then drag the frame.
- Use Fit inside a box instead if you want to keep the whole picture.
Tips for sharper pictures
- Start from the biggest original you have. Making a small picture bigger makes it blurry.
- Keep important things, such as faces and text, away from the edges, in case a platform crops a little.
- Use JPG for photos and PNG for graphics with text, then compress the file so it uploads fast.
- Check the result on your phone before you post.
Frequently asked questions
What is the difference between Fit and Fill?
Fit makes the whole picture as large as possible inside the box, so one side may be smaller than the box. Fill covers the whole box exactly and cuts off what sticks out.
Why does my picture look blurry after posting?
Platforms recompress uploads. Starting from a high-quality original at the recommended size, and not uploading a tiny or heavily compressed file, gives the best result.
