Instagram Character Counter
Count characters live against every Instagram limit: caption, bio, name, comment, alt text, and Threads.
How the Instagram Character Counter Works
Instagram enforces a different character limit for every field you can post to, and going over it either truncates your text or blocks the post entirely.
Instagram character limits
- Caption: 2,200 characters
- Bio: 150 characters
- Name (display name): 30 characters
- Comment: 2,200 characters
- Alt text: no hard limit, 125 characters is the commonly used accessibility guideline
- Threads post: 500 characters
How this tool helps
Paste your text and pick which limit to check it against. The counter updates as you type, with a progress bar that turns orange near the limit and red once you have gone over it, along with the exact number of characters remaining or over.
About the Instagram Character Counter
Instagram sets a different character limit for each field you can write in, and going over the limit can cut your text or stop your post. This counter checks your text live against the limits for captions, bios, names, comments, alt text and Threads posts.
How to Use the Instagram Character Counter
Paste or type your text into the box. Choose what you are writing for, such as Caption, Bio, Name, Comment, Alt Text or Threads post. Watch the live count and the progress bar, which turns orange near the limit and red when you go over. Edit your text until the remaining count is positive.
Tips for Better Results
Remember that the first lines of a caption are what people see before the more button, so put your key message first. Keep your bio under 150 characters and your name under 30 so nothing is cut. For alt text, aim for about 125 characters, which is the recommended length.
