An Instagram caption can hold 2,200 characters, hashtags and line breaks included, on posts, carousels and Reels alike. The feed folds it behind "more" after about 125 characters; Instagram does not publish the exact cut, and it moves with the device and your line breaks, so put the hook first.
Your bio takes 150 characters and up to 5 links. Since December 2025 a post or Reel takes up to 5 hashtags, down from 30, and a caption can tag up to 20 accounts.
Instagram now allows up to 5 hashtags in a post or Reel. They still count toward the 2,200 characters. Source
Public posts and Reels from professional accounts can be indexed by search engines, so clear keywords in a caption help people find it outside Instagram too. Source
The feed shows about 125 characters. Say the point there; the rest is for people who tap "more".
Instagram Search reads captions, and public professional posts can reach Google. Name the topic in plain words.
More than 5 is no longer allowed on posts and Reels. Pick specific ones and put them in the caption.
Short paragraphs read better past the fold. The counter's copy button keeps blank lines with an invisible character.
150 characters is about two short lines. Say who you are and what people get, and use the 5 links for the rest.
Alt text describes a photo for screen readers. Through the API it takes up to 1,000 characters on images and carousel images.

TelegramTelegram character limitsEach limit comes from Instagram's Help Center or Meta's developer reference, read on October 17, 2026. Where Instagram publishes no number, the table says "Not published" instead of repeating a figure from another guide. The 125-character fold is the commonly quoted cut, not an official one.
