Frequently Asked Questions
What is the Instagram caption character limit?
Instagram captions can be up to 2,200 characters long. This applies to regular posts, Reels, and carousel posts.
How many characters can an Instagram bio be?
Instagram bios are limited to 150 characters. This is a hard limit — you cannot exceed it.
How many hashtags can you use on Instagram?
You can use up to 30 hashtags per post. However, Instagram now recommends using 3–5 highly relevant hashtags for better reach.
Do emojis count as characters on Instagram?
Yes. Most emojis count as 2 characters towards your caption limit because they use multi-byte Unicode encoding.
How many characters show before 'more' on Instagram?
Instagram shows approximately 125 characters of a caption before truncating it with a 'more' link. This is why your opening line matters most.
Where this data comes from
The sources and check dates in this table come from one versioned data file — the place we record every check we make. The rest of this page, and the limits built into our tools, are still separate copies, so when we correct a figure we correct it in each place. This table is how we keep ourselves honest while we do.
We've checked some of these figures, not all of them yet
Some figures on this page have been checked against the platform's own documentation — those show a source and the date we checked. The rest came across from our older pages and haven't been checked yet, so they say so. We'd rather show you which is which than print a date we haven't earned.
Still to be checked against: Instagram Help Centre (help.instagram.com)

Posts, Reels, and carousels share this limit. Checked 2026-09-19: 2,200 is corroborated everywhere, but no help.instagram.com page could be located stating it directly — the Help Centre is heavily JS-rendered and resisted automated fetch. Not disproven; left unverified rather than marked confirmed without a direct citation. |

Maximum number of hashtags, not characters. FLAG 2026-09-19: an automated fetch of help.instagram.com/351460621611097 returned conflicting text on different attempts — one version said "up to 5 tags", another "up to 30 tags" (possibly different sections, e.g. product/shopping tags vs. hashtags). Could not be resolved with the tools available; needs a human check in a real browser. Value left unchanged at 30 pending that check. |
