What is the Instagram caption character limit?

The Instagram caption limit is 2,200 characters for all feed posts, including single images, carousels, and Reels. Only the first 125 characters are visible in the feed before the "more" link truncates the rest.

How many hashtags can I use on Instagram?

Instagram allows a maximum of 30 hashtags per post. This limit applies to the caption and first comment combined. Exceeding 30 hashtags can suppress your post reach, and most data shows 3 to 10 well-chosen hashtags perform better than using the full 30.

What is the Instagram bio character limit?

The Instagram bio limit is 150 characters. The display name field is separate and has a 30-character limit. Your clickable website URL does not count against the bio character count.

How long can an Instagram comment be?

Instagram comments are limited to 1,000 characters each. You can continue a long thought by replying to your own comment. Note that hashtags in comments count toward the 30-hashtag limit for the post.

What characters are allowed in an Instagram username?

Instagram usernames can only contain letters (a-z, A-Z), numbers (0-9), periods (.), and underscores (_). The maximum length is 30 characters. Spaces and special characters are not allowed in usernames.

Is the Reels caption limit the same as a regular post?

Yes, the Instagram Reels caption limit is the same as a feed post: 2,200 characters. The same truncation applies -- only the first 125 characters are visible before viewers need to tap "more".

Instagram Caption Character Limit

The Instagram caption limit is 2,200 characters for all feed post types, including single images, carousels, and Reels. Despite the generous limit, only the first 125 characters display in the feed before the "more" link truncates the rest.

For maximum impact, lead with your strongest hook or call to action in those first 125 characters. Hashtags and lengthy context can follow below the fold.

Instagram Bio Character Limit

The Instagram bio limit is 150 characters. This applies to the text portion of your bio only -- your name field, website URL, and category label each have their own separate limits.

The display name field allows up to 30 characters and is weighted more heavily in Instagram search, so include a keyword if it fits naturally. The website field accepts one clickable URL and does not count against your bio character count.

Instagram Hashtag Limit

Instagram allows a maximum of 30 hashtags per post. This limit applies across both the caption and the first comment combined -- if you put 20 hashtags in your caption and 10 in the first comment, you have hit the cap.

Posts that exceed 30 hashtags will not fail to publish, but Instagram may suppress their reach. Research consistently shows that 3 to 5 highly relevant hashtags tend to outperform posts stuffed with 30 generic ones.

Instagram Comment Character Limit

Each individual Instagram comment is limited to 1,000 characters. If you need to say more, you can reply to your own comment to continue the thread -- each reply also allows up to 1,000 characters.

Hashtags placed in comments also count toward the 30-hashtag post limit, so be mindful when building a hashtag strategy that spans caption and comments.

Instagram Username and Display Name Limits

Instagram usernames are limited to 30 characters and can only contain letters, numbers, periods (.), and underscores (_). Spaces, special characters, and most symbols are not permitted.

Your display name (the bold name at the top of your profile) is also limited to 30 characters but is more flexible -- it supports spaces and most Unicode characters, making it useful for adding a tagline or emoji alongside your brand name.

Tips for Working Within Instagram Character Limits

Write your most important message in the first 125 characters of your caption -- that is all most users see before tapping "more".

Use line breaks to separate your caption body from your hashtag block so the post reads cleanly in the feed preview.

Place hashtags in the first comment rather than the caption if you want a cleaner-looking caption without sacrificing hashtag reach.

Keep your bio to 2-3 concise lines with a clear value proposition and a call to action pointing to your link.

Avoid stuffing the full 30 hashtags -- 5 to 10 targeted hashtags typically drive better reach than 30 generic ones.
