Character Counter

A character counter shows how long your text is in real time, so you can fit it inside a platform's limit before you post — not after it's been cut off. It matters because every network truncates differently: X stops you at 280, Instagram hides all but the opening of a caption behind 'more' (about 125 characters, by common estimates), and LinkedIn collapses a post after about three lines. Counting as you write lets you land your hook before that fold and trim the rest, instead of discovering your call-to-action got buried. Paste your text, pick the platform, and the bar tells you exactly how much room is left.

Paste or type your text into the counter, choose the platform you're posting to from the dropdown, and watch the live bar. It turns amber as you near the 'visible before truncation' mark and red once you pass the hard limit, so you can see at a glance whether your hook survives the fold. Trim from the middle, keep the first line tight, and re-check. It works the same in a phone browser as on desktop — no app to install — so you can run the check from wherever you happen to be writing.

The caps most people hit: X/Twitter 280, Threads and Mastodon 500, Bluesky 300, Instagram caption 2,200 (bio 150), LinkedIn post 3,000 (headline 220), TikTok caption 4,000, Pinterest 500, and YouTube title 100 / description 5,000. But the number that usually matters is the 'visible before more' fold, which is far lower — roughly 125 on Instagram and 210 on LinkedIn by common estimates, since neither platform publishes its fold. The counter has every one of these built in, and the on-page table links each platform to a full guide on how it counts.

Because they count different things. This counter reports graphemes — the characters you actually see — so a family emoji counts as one, not seven. Word counts its own way, and X is stricter still: it wraps every link to 23 characters and charges 2 for most emoji and CJK characters. That's why a tweet that looks like 250 characters can be rejected at 280. Switch the platform to X here and the counter applies X's weighting, so the number you see is the number X will actually enforce — no surprise in the compose box.

On most platforms an emoji counts as the single character you see, even though it's several bytes under the hood — this counter reflects that by counting graphemes. X is the big exception: it counts many emoji as 2 and wraps every URL to a fixed 23 characters regardless of the link's real length. So one link plus a few emoji can quietly eat 30+ of your 280 on X. Pick X in the platform dropdown and the counter switches to that weighting; on other platforms the plain grapheme count is what you'll be charged.

No. This is a free, in-browser tool — nothing to download, no extension, no sign-up, no account. Open the page in any phone or desktop browser, paste your text, and it counts instantly; bookmark it if you want it one tap away before every post. Because it runs in the page, your text never leaves your device. If you specifically want a toolbar extension or a native app those exist elsewhere, but for a quick count before posting the web tool does the job without the install.
