Question 1

What size is an image for a Telegram post?

Accepted Answer

The best size is 1280×720 pixels (16:9): the image fills the whole message width. A 1080×1080 square also looks good, especially on a phone. Telegram shows a single image uncropped, but very elongated images look small.

Question 2

What size is a Telegram link preview?

Accepted Answer

Telegram takes the preview image from the og:image tag of the page. Make it 1200×630 (1.91:1) and the preview will be large, full width. In OG Studio this is the “Open Graph” format. How to make such a cover and connect it to your page is explained in our link preview guide.

Question 3

What size is a channel avatar?

Accepted Answer

A channel avatar is 640×640 pixels or more; Telegram shows it as a circle, so keep the important part in the center. You can build a 640×640 square in the OG Studio editor.

Question 4

Can I make an image right inside Telegram?

Accepted Answer

Yes: send a topic or a link to the @ogimg_bot bot and it sends you a ready image. Channels also get auto-covers (Pro): the bot makes a cover for every new post in the style of your Brand Kit.

Question 5

Which aspect ratio should I pick for Telegram?

Accepted Answer

For an image in a post use 16:9 (1280×720) or 1:1 (1080×1080), for a link preview 1.91:1 (1200×630), for an avatar 1:1 (640×640). No sign-up is needed for this: signing in by email or through Telegram is required only for Pro and for saving projects.
