Instagram caption limit: 2,200 characters · Feed preview truncates after about 125 characters with a 'more' link. SherpaPost shows the exact cutoff and line breaks before you publish.
An Instagram post preview is a pixel-true mockup of how a caption, image, carousel, or reel will render inside the Instagram app before you publish. SherpaPost reproduces the exact feed layout — username row, image crop, caption with the 'more' truncation at ~125 characters, hashtag spacing, and reel safe zones — so you can fix line breaks, emoji placement, and hook framing without burning a real post.
Instagram lets you write up to 2,200 characters and 30 hashtags, but the feed only shows roughly the first 125 characters (about one and a half lines on mobile) before collapsing the rest behind a 'more' link. Line breaks count toward that cutoff, so a caption that looks fine in a text editor often loses its hook in the live feed. SherpaPost marks the exact cutoff line for every draft.
Schedulers post to Instagram through the Graph API, which means account-linking, token expiry, and the risk of failed or shadow-banned posts. SherpaPost never connects to your Instagram account. You preview, polish with AI, then publish manually from the official app. No API risk, no permissions to grant, and the free plan is genuinely free.
