Through Telegram's Bot API, which schedulers use, a plain-text message holds 4,096 characters and a caption under a photo, video or album holds 1,024. Links, @mentions, #hashtags, emoji and line breaks all count toward it.
In the Telegram app, Premium users can write captions of up to 4,096 characters, and since July 2026 the Premium Rich Text Editor sends up to 32,768 characters in one message. Bots got rich messages of the same size in June 2026. OmniSocials sends plain text, so 4,096 and 1,024 apply, and a longer caption goes out as a reply under the media.

Premium's 4,096-character captions and 32,768-character rich messages work in the app. A plain scheduled post gets 4,096 and 1,024.
Telegram turns links, @mentions and #hashtags into links by itself. They count toward the limit like any other text.
Each answer takes 100 characters, but short answers are easier to read and tap on a phone.

The Bot API is what schedulers use, so where the app differs (Premium captions, rich text), the table shows both. Telegram publishes no plain-text limit for its apps; the 4,096 figure is the Bot API's.
