Instagram Character Counter

How to use

1. 1Pick a device target with the Mobile / Desktop toggle. The feed caption preview and '...more' cutoff update to match.
2. 2Type or paste your caption, bio, username, display name, comment, alt text, story text, direct message, and LIVE title into the fields on the left. Each field shows a live grapheme count, a colored progress bar, and a 'characters left' line.
3. 3Watch the right column for live previews: a feed caption preview with the '...more' cutoff, a profile preview with the full bio, a search row preview with the ~55 character truncation, and a follow-suggestion card preview with the ~80 character cutoff.
4. 4Review the caption analysis panel for lines, hashtags, at-mentions, links, and emoji. Watch the per-post (30) and per-Story (10) hashtag caps and any tag that goes over the practical 30 character single-tag limit.
5. 5Watch the username validation list for Instagram's lowercase, period, and underscore rules.
6. 6Click Load sample to see a worked example, Clear all to reset every field, or Copy report to grab a plain-text summary of every counter for handoff or QA.

About this tool

Instagram Character Counter is a free in-browser counter that mirrors every published Instagram text limit in a single place, so a creator, social media manager, or marketer can write a feed or Reel caption, bio, username, display name, comment, alt text, story sticker text, direct message, and LIVE title side by side and see exactly where each field will be cut off or rejected. The feed and Reel caption budget is 2,200 characters and that budget includes every hashtag, every at-mention, and every emoji you place in the caption, so the tool tags hashtags and at-mentions as you type and shows their combined character cost. Instagram also caps the number of hashtags per post at 30 (and per Story slide at 10), with a practical per-tag length of about 30 characters, so the analysis panel surfaces the hashtag count next to both caps and flags any single tag that is over the practical per-tag limit. The bio cap is 150 characters and the bio renders in a few different places: full on your profile, often cut around 55 characters in search rows, and around 80 characters on follow-suggestion cards. The username cap is 30 characters with Instagram's specific rule that only lowercase letters, digits, periods, and underscores are allowed, plus the period cannot start or end the handle and two periods cannot sit next to each other; the tool validates against all of these rules and shows a clear list of issues, with a softer warning if you typed an uppercase letter that Instagram will lowercase for you. Display name is 30 characters of free-form unicode including emoji. Comments and replies cap at 2,200 characters each. Alt text caps at 100 characters per image, set per image in a carousel. Story sticker text caps around 250 characters per sticker. Direct messages cap at 1,000 characters per single send. LIVE titles cap at 50 characters. A feed caption preview shows the first ~125 characters (mobile) or ~280 (desktop) above the '...more' link so you can place the hook above the fold. A profile preview shows the full bio rendering on the profile, and a search row preview plus a follow-suggestion card preview show the ~55 character and ~80 character truncation points. All counting is grapheme cluster aware via Intl.Segmenter where available, so flag emoji, surrogate-pair pictographs, and accented letters built from combining marks each count as one character, matching the Instagram composer. Useful for creators, social media managers, content marketers, photographers, agencies, and anyone writing copy for an Instagram post.
