Key takeaways
- Telegram recommends 1280×720px (16:9) or 1280×1280px (square) for channel post images, and 512×512px for a profile or channel photo.
- Telegram compresses photos sent as "photo" attachments more aggressively than most platforms — sizing correctly upfront still gives the best result.
Telegram image size: telegram image dimensions
- Channel post image (landscape): 1280 × 720px (16:9)
- Channel post image (square): 1280 × 1280px, displays prominently in the feed
- Profile picture / channel photo: 512 × 512px, displayed as a circle
- Neither side of an uploaded photo should exceed 1280px
Why Telegram compresses images more than other platforms
Telegram applies stronger compression to images sent as a standard "photo" than platforms like Instagram or LinkedIn; staying within its recommended 1280px-max dimensions and a reasonable starting file size limits how much detail that compression removes.
Sizing images before a bulk import
Sizing media correctly before a bulk import avoids a platform recompressing or cropping it unpredictably after upload — worth checking before scheduling a large batch.
