Formatted Reading Preview
Simulating Instagram caption rendering & fold threshold
Start typing in the editor — your formatted caption appears here exactly as Instagram will render it.
Clipboard Safety & Browser Isolation
Some mobile browsers and embedded webviews restrict automatic clipboard writes. If one-click copy fails, open the manual buffer and copy the clean text yourself — the spacers are already in place.
Caption Architecture Guidelines
Three rules for higher retention and scroll-stopping engagement.
- Critical area120 – 130 chars01
Hook before character 125
Instagram truncates captions after roughly two lines on mobile feeds. Make sure your question, punchline or value proposition is fully legible before the fold.
- Ideal paragraph18 – 35 words02
Breathing room reduces bounce
Dense walls of text get scrolled past. Break thoughts into one- or two-sentence paragraphs separated by clean invisible spacers.
- Hashtag range3 – 8 niche tags03
Isolate hashtags & metadata
Keep discovery tags and calls to action at the very bottom, after a preserved blank line, so they never dilute your main narrative.
3-Step Caption Clean-Up
Paste Your Draft
Drop in a caption straight from your notes app, with messy spacing, trailing spaces and however many blank lines you like.
Pick the Rules
Toggle line-break preservation, blank-line collapsing and trailing-space trimming. The preview updates live and shows exactly where the “… more” fold lands.
Copy & Paste
One click copies the clean caption with invisible spacers in place. Paste it into Instagram, a scheduler or your bio — the paragraphs stay intact.
