A Reels ad should be understandable on a phone and work in the actual placement preview. Plan product, text and crop together before producing final files.
Confirm the placement and deliverable
Ask the person running advertising to specify the placement, destination and required file. Meta's Ads Guide, read on 25 October 2026, lists a 9:16 ratio at 1440 x 2560 pixels for Reels video ads, up to 15 minutes on Instagram Reels, no maximum length on Facebook Reels and a 4 GB file limit. Check current upload requirements in the account rather than reusing an old specification sheet. The actual display and use of the material form part of the review.
AI Vidia's Performance Retainer supplies 9:16 videos up to 30 seconds. That describes our deliverable, not every supported Reels duration or a complete platform specification. Agree additional formats separately. Which Facebook and Instagram placements the 9:16 master covers, and when a 4:5 Feed version is agreed, is on our Facebook and Instagram ad creative page.

Compose for vertical viewing
Show the product at a size that makes the relevant detail visible. Cropping a wide image can remove hands, packaging or the part of the scene that explains use. Plan framing while the script and scene can still change.
Leave room for text and essential details around the actual interface. Meta's Ads Guide suggests keeping roughly 14% of the top, 35% of the bottom and 6% on each side free of text, logos and other key elements, and Facebook Reels does not auto-caption ads, so burn the captions in. Use the placement preview to check whether buttons or other elements cover anything important.

A hypothetical coffee-grinder storyboard
Suppose you want to show the container, control button and result. Start with a vertical storyboard in which each frame has a clear purpose. A button close-up can explain operation while another shot establishes size.
If a long subtitle covers the essential product detail, shorten the wording or reposition it. If AI cannot depict the required motion correctly, film it or use another visual approach. This is a planning example, not performance evidence.
Watch without sound too. The main explanation should still make sense when audio is not heard. This checks your message without assuming that every Reels viewer behaves the same way.
