Instagram caption formatter
Make captions that keep their spacing, show the right words before “more”, and keep hashtags out of the way.
Updated November 2026
On Instagram the image or video does the heavy lifting, and the caption has a split second to add context. Only the first line or two appears under the post, so your opening must work on its own — and everything else needs to survive Instagram's habit of swallowing line breaks.
The Instagram fold
Captions can be up to 2,200 characters with a maximum of 30 hashtags. In the feed, Instagram shows roughly 125 characters (about two lines) in the app before truncating with … more; desktop shows a little more. Your username is displayed in front of the caption and takes up part of that first line, which is why short hooks work best. Our preview includes the username so you see the real fold.
Why your line breaks disappear
Instagram often removes empty lines or trailing spaces when text is typed directly in the app, and some keyboards insert characters that break spacing. Composing in a clean editor and pasting the finished caption is the most reliable approach. The Instagram preset trims every line, removes stray double spaces and keeps your paragraph structure intact before you copy.
Hashtags: in the caption or in a block?
Keep the story clean
Hashtags sprinkled through a sentence make it harder to read. Moving them to the end keeps the message clear.
Fewer, sharper tags
Three to ten specific, relevant tags usually outperform thirty generic ones. Our scorecard flags anything outside that range.
No duplicates
Repeated tags add nothing. The Instagram preset pulls every tag into one block and removes duplicates automatically.
Mind the case
Using CamelCase like #SpringDrop makes multi-word tags readable for everyone, including screen-reader users.
Writing the first line
Treat the first 125 characters like a headline. State the benefit, ask a question, or describe what's happening in the image. Calls-to-action such as “link in bio” work better near the top than buried under a block of hashtags. Emoji can add personality, but more than a handful per caption starts to feel busy — the scorecard counts them for you.

Open the studio with InstagramPosting from your computer
Instagram doesn't allow other websites to pre-fill a caption, so the Copy & open Instagram button copies your formatted caption to the clipboard and opens Instagram in a new tab. Start a new post and paste — your spacing and hashtag block arrive exactly as previewed.
