Reels inventory is Meta's fastest-growing surface. The bar for creative here is "does it look like a native creator post," not "does it look like an ad." Anything that looks studio-produced gets skipped in <1 second.

Design tips that actually move the needle
- 01Sound-on-first. ~85% of Reels play with sound. Silent product cuts feel off-platform.
- 02Hook in the first 1s — a face, a hand entering frame, or on-screen text that answers a question.
- 03Vertical native — no cropped 16:9 with black bars, ever.
- 04Length 6–15s outperforms 15–30s outperforms 30–60s. Pick the shortest that tells the story.
- 05Keep product/logo in the top 60% of the frame — bottom is CTA + caption territory.
People also ask
What's the ideal Reel length for an ad?+
6–15 seconds. Anything longer collapses completion. Meta's own creative playbook flags 15s as the sweet spot for full-funnel ads.
Should Reels ads have music?+
Yes — but licensed for commercial use. Meta's ad library music is safe; trending organic sounds are not (they get muted on paid distribution).
Reel vs Story: which to run?+
Reels reach more non-followers and have longer runtime headroom, but require more polish. Stories are cheaper to produce and better for retargeting known audiences.

For Instagram Reel, a 9:16 aspect ratio is 1080×1920 pixels. Any resolution with the same ratio works, but 1080×1920 px is the recommended native size and avoids upscaling.
