Caption length and video duration, checked against two different limits
The example caption 'Day in the studio with three tools you can ship before lunch.' runs 61 characters -- 2,139 characters left before TikTok's 2,200-character caption cap. Separately, a 38-second video against a 180-second account max fits comfortably within that duration limit.
These two checks are independent of each other: a caption can be well within the 2,200-character limit while the video itself exceeds the account's duration cap, or vice versa -- both need to pass for the post to actually work as intended.
The 2,200-character caption cap is generous enough that most captions never come close to it -- the more common practical constraint is how much of the caption displays before TikTok's UI truncates it with a 'more' link, which happens at a much shorter length than the full 2,200-character limit.
Why account-level duration limits vary
Caption cap is configurable. Account-level duration limits still apply on-device. TikTok's maximum video length has expanded over time and can vary by account (newer accounts, or accounts without certain features unlocked, may have a shorter cap than the platform's current maximum), which is why this calculator lets you set your own account max rather than assuming one fixed number.
The duration limit checked here is enforced by the TikTok app itself at upload time -- if a video exceeds your account's actual max, the app will require trimming before it can be posted, independent of anything this calculator shows.
Caption length and hashtags share the same 2,200-character budget on TikTok -- a caption padded with many hashtags eats into the same character allowance as the descriptive text itself.

If the visual safe zone for on-screen text or effects (not the caption) is the concern, the TikTok Safe Zone Previewer covers that separately.
Frequently Asked Questions (FAQ)
How many characters can a TikTok caption have?
The standard cap is 2,200 characters, which includes any hashtags typed as part of the caption text. The example caption here uses only 61 of those, leaving 2,139 remaining.
Does the video length limit apply to every TikTok account equally?
Caption cap is configurable. Account-level duration limits still apply on-device. Not necessarily -- TikTok's maximum video length has changed over time and can differ by account based on which features are unlocked. Set the account max field to your actual current limit rather than assuming a single universal number.
What happens if my video exceeds my account's actual duration max?
The TikTok app itself will require trimming the video before you can post it -- this calculator flags whether your entered duration fits your entered max, but the app enforces the real limit at upload time regardless of what this tool shows.
Do hashtags count separately from the caption's character limit?
No. Hashtags typed within the caption count toward the same 2,200-character total as the rest of the caption text -- there's no separate hashtag character allowance.
Is there a practical display limit shorter than 2,200 characters?
Yes, informally. TikTok's app UI truncates displayed captions with a 'more' link well before the full 2,200-character cap is reached, so very long captions require a tap to expand -- worth considering for the most important information in a caption.
