First line under 60 characters: a 200-post test
Used Typefully to draft and tag 200 posts by first-line length, published over 8 weeks, to see if hook length moves reach on Threads.

— First lines under 60 chars: 1,420 median views
— First lines 60-150 chars: 980 median views
— Same body content; only the opening line length varied

Short hooks won by 45%. Threads truncates the preview, and a complete short hook outpulls a cut-off long one every time.

Standout feature: Typefully shows the truncation point as you type, so you see exactly where the feed will cut. Annoying limitation: that preview is calibrated to X, not Threads, so it's a rough guide, not exact.

Verdict: write hooks that finish in one line. Typefully: Worth it as a drafting tool at 12.50 dollars.
