TikTok

Everything you need to schedule posts on TikTok: what you can do natively, text limits, image and video sizes, the schedulers that support it, and recent API changes.

Facts checked 25 Oct 2026

Can you schedule natively?

Unclear

TikTok's own business blog describes scheduling from the web upload page, 15 minutes to 10 days ahead, for creators and Business Accounts, with no editing after scheduling. That post is undated and no current help page confirms the limits, so check TikTok Studio for today's options.

Step-by-step guide

Text limits

FieldLimitHow it counts
video caption 2,200 characters 2,200 is the documented API limit. The app may allow more, but TikTok does not document it. Source
Check a draft in the character counter

Image and video sizes

Only what TikTok documents. "Not stated" means the platform doesn't publish that figure; we don't fill gaps from blogs. Ads specs are marked, because they can differ from normal posts.
