Q: "Long captions or short? Does it actually change anything?"

Q: "Long captions or short? Does it actually change anything?"

Short answer: longer captions doubled saves for this account, but only on educational content.

The case: an Instagram business page tested 150-character captions vs 600-character ones across 30 posts. On entertainment posts, length made no difference. On tips/educational posts, the long captions drove 2.1x more saves and 60% more time-on-post — and dwell time fed reach, lifting it 34%.

Here's why: a detailed caption turns the post into a mini-resource people save to revisit. Verdict: match length to intent. Long captions for value, short for vibes. Don't write essays under a meme.
