Social media image size guide
Image sizes and aspect ratios for Instagram, YouTube, X and LinkedIn taken from each platform’s own help pages, plus a ratio calculator.

What it does
Pictures made at the wrong shape get cropped. This page lists the sizes the platforms themselves publish, and the calculator above gives the height for any width and aspect ratio.
| Where | Size or ratio | Source |
|---|---|---|
| Instagram feed photo | At least 1080 px wide, aspect ratio between 1.91:1 and 4:5 (1080×566 to 1080×1350; square is 1080×1080) | Instagram Help |
| Instagram Reels | Any ratio from 1.91:1 to 9:16; a full-screen vertical reel is 9:16, for example 1080×1920 | Instagram Help |
| Instagram Stories (ads) | 1080×1920 recommended (9:16) | Meta Business Help |
| YouTube channel banner | 2560×1440 recommended, 2048×1152 minimum, text and logo inside the central 1235×338, file up to 6 MB | YouTube Help |
| YouTube video thumbnail | 16:9, for example 1280×720 or larger | YouTube Help |
| X header photo | 1500×500 | X Help |
| X profile photo | 400×400 | X Help |
| LinkedIn profile background | 1584×396 | LinkedIn Help |
Checked on 14 November 2026. Platforms change these without notice, so follow the source link before a big job. Sizes for Facebook and WhatsApp are not listed because we could not confirm them on an official page; for a WhatsApp Status, a full-screen vertical 9:16 picture such as 1080×1920 fills a phone screen.
How to use it
- Find the place you are posting in the table.
- To make a picture at a given ratio, enter the width and choose the ratio above. The tool gives the height.
- Keep faces and text away from the edges, since apps crop and overlay buttons there.
Worked example
A 4:5 portrait picture 1080 px wide is 1080 × 1350. A 9:16 picture 1080 px wide is 1080 × 1920.
How it works
An aspect ratio is width divided by height. For a ratio a:b and width w, height = w × b ÷ a, rounded to a whole pixel. 1:1 is a square; 4:5 is a little taller than wide; 9:16 is the shape of a phone held upright; 16:9 is the shape of a television.
Questions
What happens if my picture is a different shape?
The platform crops it or adds bars. Making the picture at the right ratio keeps control of the framing with you.
Does a bigger image look better?
Up to the size the platform displays. Beyond that it is scaled down and compressed, so there is little gain.
PNG or JPG?
JPG for photographs. PNG for graphics with text, flat colours or transparency.
