Social Media Character Counter

The caps vary a lot. X gives you 280 characters, Threads and Pinterest 500, a LinkedIn headline 220 and a LinkedIn post 3,000, Instagram and TikTok captions 2,200 each, a YouTube title 100 and its description 5,000, and Facebook a generous 63,206. Go over and the platform either cuts your text or refuses to post it.

This tool checks your text against all of them at once, so you can see at a glance where it fits and where it spills over, instead of writing for one platform and getting surprised on another.

The hard cap is rarely your real problem. What matters is where the feed collapses your post behind a "see more". LinkedIn hides everything after roughly 210 characters on mobile, and Instagram after about 125. Those cutoffs come long before the limit.

Your hook has to land before that fold, because most people decide whether to tap based only on the visible lines. A post can be well under the character limit and still fail because the interesting part is hidden. The tool flags both cutoffs so you write for the part people actually see.

Cut the throat-clearing first line and lead with your sharpest idea. Break one long sentence into two short ones so it reads faster. Move background and context below the fold, and keep the payoff up top where it earns the tap.

When you are close to a limit, look for filler words and hedges first. They add length without adding meaning, and removing them usually gets you under the count without touching anything that matters.
