Instagram caption tips: line breaks, hashtags and length
Long blocks of text get skipped, and blank lines between paragraphs can disappear when you post. This Instagram caption formatter keeps your spacing exactly as written, counts characters against the limits, and checks your hashtags against Instagram's current rule of 5 per post.
Caption and bio limits
- Caption: up to 2,200 characters, but only about the first 125 show before "more".
- Hashtags: up to 5 per post or reel, down from 30 in December 2025.
- Bio: up to 150 characters.
How to write a caption people read
- Hook first: a question, bold claim or result in the first line.
- Short paragraphs: one idea each, separated by blank lines.
- A clear call to action: save, share, comment or visit the link in bio.
- 3–5 specific hashtags at the end: describe the post precisely rather than using huge generic tags.
Links in captions can't be tapped, so put them in your bio. Pair a great caption with a correctly sized image from the Instagram resizer.
Questions
Why do my blank lines disappear?
Empty lines can be removed when a caption is posted. This tool puts an invisible character on each blank line so your spacing stays exactly as you wrote it.
How many hashtags can I use?
Up to 5 per post or reel. Instagram lowered the limit from 30 in December 2025. A few specific hashtags work better than broad ones anyway.
How much of my caption do people see?
Only about the first 125 characters, or the first two lines, before "more". Put your hook there. Captions can be up to 2,200 characters and bios up to 150.
