Get the exact pixel size for every social platform before you design. Pick a preset, or enter custom dimensions, and this tool instantly shows the aspect ratio, orientation, and resized height for any target width.
Aspect ratio: 1:1 · 1080×1080 · at 400w → 400h
Why the right size matters
Platforms crop and squeeze images that don’t match their preferred ratio — a portrait pin scaled badly, a Facebook link card that cuts the headline, a thumbnail squashed on mobile. This calculator runs entirely in your browser so you always export from the correct canvas.
Presets included
- Instagram Square 1080×1080 and Portrait 1080×1350
- Story, Reels & TikTok vertical 1080×1920
- Facebook and LinkedIn link cards (1200×630 / 1200×627)
- Pinterest Pin 1000×1500 and YouTube Thumb 1280×720
- X / Twitter 1600×900
How to use it
- Pick a preset to fill the width and height automatically.
- Or type any custom size — the ratio updates live.
- Scale to a target width to know what height to set before exporting.
- Copy the dimensions block when you need to share the specs with a client or teammate.
