How to use this list
Choose the platform and the format you are making, then click a size to copy it into your design tool. Every card links to the official page the numbers come from, so you can check them yourself before a big launch.
Ratio, recommended size and minimum
The ratio is the shape of the image or video. 1:1 is a square, 4:5 is a bit taller than a square, 9:16 is a full phone screen and 1.91:1 is a wide landscape image.
The recommended size is what the platform suggests for a sharp result. The minimum is the smallest file it accepts. Export at the recommended size, because a file at the minimum can look soft on a big screen.
Tips that save a round of fixes
- Make a separate version for each shape you need instead of letting the platform crop one file. Text and faces near the edges are the first to get cut.
- In 9:16 Stories, Reels and TikTok the app puts its own buttons and text over your video. Keep words, logos and the offer away from the edges and check the frame with the Safe zones tool.
- Read the text limits carefully. Some are hard limits and the platform will not accept longer text, others are recommendations and longer text gets cut on screen. Put the most important words first either way.
- Name files by platform and ratio, for example spring-sale-4x5.jpg, so nobody uploads the wrong version.
FAQ
Do these specs change?
Yes. Platforms update their specs and add new formats several times a year. We checked every number in October 2026 and every card links to the official source, so open it before you rely on a number for a big launch.
Which sizes should I make if I only have time for a few?
For Meta, a 4:5 version for Feed (1440 × 1800) and a 9:16 version for Stories and Reels (1440 × 2560) cover most placements. Google Display, Demand Gen and Performance Max also need a 1.91:1 landscape image (1200 × 628) and a 1:1 square (1200 × 1200). TikTok and YouTube Shorts are made for 9:16.
What happens if my file has a different ratio?
Depending on the placement, the platform crops it, adds empty space around it or does not accept it. That is why it pays to export each ratio separately and look at it in a preview before you publish.
Why does a card say "not stated"?
Because the platform does not give that number on its official page. We would rather leave the field empty than guess, since a wrong number costs more than a missing one.
