Before you use it
Keep the useful details true.
- Platforms change display behaviour and may vary by placement, device, account, language, or campaign type.
- Use these as planning cues, not a promise of an exact in-app cutoff.

- 01
Paste the draft you want to check.
- 02
See the character count and planning thresholds.
- 03
Edit for clarity first, then check the destination platform before publishing.
Common questions
Should every caption be short?
No. Use the length that makes the offer or update clear; a useful caption matters more than filling a limit.
