How to Count Characters for a Tweet, Bio or Meta Tag

Every text field has an invisible wall: 280 characters for a tweet, 150 for an Instagram bio, about 155 for a meta description. Go over and your words get cut off. Here's how to count characters and stay under any limit.

Count characters live

Paste or type into the character counter and watch the count update as you go — characters, words and lines, so you always know how close you are to the wall.

The limits worth memorising

Tweet/X post: 280 · Instagram bio: 150 · Instagram caption: 2,200 · Meta description: ~155 · Meta title: ~60 · Google Ads headline: 30. Hitting these exactly makes content look intentional.

Platform-specific counters

Fine-tune for X with the tweet character counter, and craft a bio that fits with the Instagram bio generator.

Why "characters" not "words"

Social and SEO fields count characters (including spaces and emojis), not words — because display space is fixed. One emoji can even count as two. When a field truncates, it's counting characters, so that's what you should watch.

Trim to fit

Over the limit? Cut filler words, drop hashtags from bios (they help in captions, not bios), and use the text cleaner to remove extra spaces that quietly eat your character budget.
