Check your caption against Instagram’s real limits as you type — 2,200 characters, 30 hashtags, and the first-line hook that decides whether anyone taps “more.”
A great caption can’t save a reel the algorithm has seen before. TrialReel re-cuts your videos into genuinely new edits every day — and writes a caption to match each one — so you always have something fresh to post.
2,200 characters is the maximum, but only about the first 125 show before Instagram cuts it with “more.” Front-load the hook — the reason to keep reading — in that first line.
30 hashtags is the cap. A handful of specific, relevant tags almost always beats cramming in all 30; generic tag dumps can read as spammy.
Line breaks are preserved as you type them, so you can space a caption out for readability. This tool previews your caption exactly as the breaks will appear.
