Every place you publish has a ceiling, and nobody can remember all of them. This page lists the common ones and measures your text against each at the same time, so you can see where your draft fits and where it needs trimming.
Paste your text. The table shows each limit, how many characters you have left, and whether you are over.
The limits listed
Search results first. A Google title tag shows about 60 characters before being cut off; the real limit is based on pixel width, so wide letters like W take more room than narrow ones like i, and 55 to 60 characters is a safe range. A meta description is shown at roughly 155 to 160 characters on desktop and slightly less on mobile. Neither is a hard limit on what you can write, only on what is displayed.
Social platforms next. An X post is 280 characters, with every link counted as 23 regardless of its length and some languages counted double. An Instagram caption can reach 2,200 characters, but only about the first 125 appear before “more”, so the opening needs to carry the message. An Instagram bio is 150. A LinkedIn post can be 3,000, with the first 210 or so visible before “see more”. A Facebook post has an enormous limit, but short posts tend to get more engagement. A TikTok caption is 2,200, and a Pinterest pin description 500. YouTube allows 100 characters in a title, though only the first 60 or so appear in search and suggestions, and 5,000 in a description.
Texting last. An SMS is 160 characters in a single segment, but only when it uses the basic GSM alphabet. One emoji or accented letter outside it switches the whole message to a different encoding with a limit of 70 per segment, so a short, chatty text with a single emoji may be billed as two or three messages.
How the count is made
The tool counts what a reader sees: each visible symbol once. That is close to what most platforms do, but not identical. Some platforms count an emoji as two characters, X counts differently for certain languages, and SMS segments depend on encoding. So treat the figure as a good guide and leave a small margin for anything tight.
Platform limits also change from time to time, and several of the numbers above have moved over the years. Check the platform’s own help page for anything that really matters, such as an advertising limit that gets your post rejected.
Trimming
If you are over, the text truncator cuts text at a limit without chopping words in half, and remove extra spaces takes out padding that counts against you. For the full breakdown of counts, including bytes, see the character counter. For length in words, the word counter is the place.
