Reels caption length checker
Paste a draft caption and see live character count against approximate Instagram Reels, TikTok, and YouTube Shorts UI limits — plus whether your first-line hook fits above the “… more” fold. Runs in your browser; no signup.
Caption checker
Empty draft. Instagram Reels hard limit ≈ 2,200 characters; preview fold ≈ 125.
Paste a caption — put your strongest hook on the first line (aim under ~80–100 characters so it stays visible before “more”).
Optional: add a few relevant hashtags after the hook — stuffing dozens rarely helps readability.
IG captions are commonly capped near ~2,200 characters; feeds often truncate around ~125 before “more”. Limits are approximate public UI figures, not guarantees.

FAQ
Quick answers about short-form caption length and first-line hooks.
How long can an Instagram Reels caption be?
Instagram captions are commonly limited to about 2,200 characters. Feeds often truncate around ~125 characters before a “more” control. Treat these as approximate UI limits — Instagram can change them without notice.
What about TikTok and YouTube Shorts caption limits?
Many TikTok accounts see roughly ~2,200-character captions (some eras/regions report up to ~4,000). YouTube Shorts descriptions can run much longer (~5,000), but titles and above-fold snippets are far shorter. This tool labels each preset as an approximate platform UI limit, not a guarantee.
Why does the first-line hook matter?
On Reels, TikTok, and Shorts, viewers often only see the first line before tapping “more”. Aim for a hook under ~80–100 characters so the pitch stays visible above the fold.
