Caption Character Counter

Write one caption and check it against every platform's character limit — and see exactly where it gets cut off in-feed.

0 characters

Write a caption above, then check it against every platform's limits at once.

How to check your caption length

  1. 1

    Write or paste your caption

    Type or paste the caption you're planning to post.

  2. 2

    Check it against every platform at once

    See your caption's length compared to the hard character limit and in-feed truncation point for Instagram, Facebook, X, LinkedIn, TikTok, YouTube, and Pinterest simultaneously.

  3. 3

    Trim to fit before the truncation point

    If a platform truncates your caption sooner than its hard limit, move your hook earlier so it isn't hidden behind a "more" link.

2026 caption limits by platform

The hard limit is the most a platform allows before it rejects the post. The truncation point is where the feed hides the rest behind a "more" link — often much shorter than the hard limit, and the number that actually matters for whether your hook gets seen.

Platform Hard limit Feed truncates at
Instagram 2,200 ~125 chars
Facebook 63,206 ~477 chars
X (Twitter) 280 No separate truncation
LinkedIn 3,000 ~210 chars
TikTok 2,200 ~150 chars
YouTube (description) 5,000 ~125 chars
Pinterest (description) 500 No separate truncation

Frequently asked questions

What's the difference between a character limit and a truncation point?

The limit is the hard maximum a platform allows before rejecting a post. The truncation point is where the feed cuts the text short behind a "more" link, even when the caption is well under the limit — the number that decides what people actually see first.

Why does Facebook allow such a long caption?

Facebook's hard limit is over 60,000 characters, but almost nobody sees that much — the feed truncates to roughly the first 477 characters before showing "See more". Write your hook in that first stretch.

Does X (Twitter) truncate captions the same way?

No — X has a hard 280-character limit and no separate truncation behavior. If it's under 280 characters, the whole thing shows.

Are these limits guaranteed accurate?

They're based on widely-cited, current platform behavior, but platforms change these numbers without much notice. Treat this as a strong starting point, not a guarantee — if a caption is right at the edge, double-check on the platform itself before publishing.

Does this tool store or send my caption anywhere?

No. Everything is calculated in your browser — your caption is never sent to a server.
