Tips for Staying Within Limits
- Front-load your key message. Most platforms truncate long posts in the feed. The most important information — your hook, CTA, or key point — should appear in the first 100–150 characters.
- Count hashtags. On TikTok and Instagram, hashtags count toward the caption limit. Budget space accordingly.
-
URLs on X/Twitter. All links are shortened to 23 characters by X's
t.coshortener, regardless of the actual URL length. - Write, then trim. Write your full thought first, then cut filler words, passive voice, and redundant phrases.

Frequently Asked Questions
Does this counter count emojis as one character?
Most emojis are encoded as two UTF-16 code units and are counted as 2 characters by many platforms, including X/Twitter. This counter uses JavaScript's length property, which matches the way most social media platforms count characters.
Do spaces count as characters?
Yes, spaces count as characters on every social media platform. This is standard behavior for all character counting.
Why does my post look fine in the app but this counter shows it's over the limit?
Platform apps occasionally allow slightly longer text in their drafts before enforcing the limit at post time. Always verify in the actual platform's compose window before publishing. Platform limits can also change — check the platform's current documentation for the latest limits.
