What are the character limits and image rules for each social platform?
Each social platform sets its own text and image rules. Check the limits below before you publish. The app allows one Library image per post and shows a warning when a selected profile needs a change.
Text limits and image rules
| Platform | Text limit | Image rule |
|---|---|---|
| X | 280 characters | Optional. A link counts as 23 characters. |
| 20,000 characters | Optional. Connect a Page. | |
| 2,200 characters | Required. JPG or PNG, from 4:5 to 1.91:1. Use a Business or Creator account. | |
| 3,000 characters | Optional. | |
| TikTok | 4,000 characters | Required. Add a description. |
| 500 characters | Required. Choose a board. | |
| Bluesky | 300 characters | Optional. Large images are reduced to fit. |
| Threads | 500 characters | Optional. |
| Google Business Profile | 1,500 characters | Up to one image. Text is required. |
These are the rules the app checks for a post. The publish window shows the exact problem beside a profile when a post does not fit.
