Meta Ad Creative Specs: Placements, Ratios and Safe Zones
What each Facebook and Instagram placement wants from a piece of creative, and how to plan one batch that covers all of them.
Planning guide Written by the studio from its own practice; where it states a view, the view is the studio's. Figures quoted from a platform are attributed to that platform's documentation under Sources and should be verified at upload.

This guide covers the creative side of Meta specifications: the aspect ratio each placement is built around, the areas of the frame the interface covers, the sound-off default, and how a single brief turns into a set of masters that fit every placement. Platform requirements change; treat the figures here as a planning frame and confirm the current limits against Meta's published documentation before upload. It is written for the marketer briefing the work, whether that is an in-house team or a studio such as Meta ad creative production at Unreal.

One brief, four ratios
Meta places the same ad across surfaces that do not share a shape. Reels and Stories fill a phone screen at 9:16. The feed reads best at 4:5, with 1:1 as the safe fallback for placements that crop. Right-column and some link placements sit near 1.91:1. A batch planned from the start as a 9:16 master with a 4:5 and 1:1 re-composition beside it (not a crop) covers the set; a piece composed for one ratio and cropped to the others loses its headline, its product or its captions in at least one of them.
Where the interface sits
On Reels and Stories the caption, profile name, call-to-action and engagement controls sit over the bottom of the frame and along the right edge. Type, product shots and on-screen captions placed there are partly hidden. Keep the message inside the central band of the frame, leave the lower fifth and the right-hand rail for the platform, and check the finished piece in the placement preview rather than on a bare player. Meta publishes the exact safe-zone dimensions; they move, so confirm them at upload.
Sound off by default
Most feed and Stories impressions start muted. A piece that depends on its voiceover to make sense has already lost the viewers who never unmuted it. Burned-in or platform captions carry the script; the first frame carries the product and the promise; the sound is a layer that rewards the viewers who turn it on. Reels is met with sound on more often than the feed, but the same discipline holds.
Length by placement
Stories play in short cards, so a 15-second piece is the natural unit and anything longer is split. Reels allow more, but attention in the first seconds decides whether the rest plays. Feed video is skimmed, not watched, so the opening frame is the whole argument for many viewers. Plan the hook as a standalone: if only the first three seconds played, what would the viewer know?
Static and carousel creative
Image ads follow the same ratio logic (4:5 for the feed, 9:16 for Stories, 1:1 as the fallback) with one extra constraint: text laid over the image should stay clear of the same interface areas as video. Carousel cards are square or 4:5 and read left to right, so the first card has to work alone and the set has to work as a sequence. Product renders and lifestyle stills sized for these placements are covered on the AI product photography page.
Planning one batch for all of it
Write the concept once, then list the deliverables as a grid: each concept, each hook variant, each ratio. That grid is what a production scope should name, and it is how a media buyer sets up a placement-aware test rather than uploading one file everywhere. A batch organised this way is also what performance creative means in practice: isolated variables, delivered in every ratio the placements need.

Frequently asked questions
What aspect ratio should a Meta video ad be?
9:16 for Reels and Stories, 4:5 for the feed, and 1:1 where a placement crops. Composing a 9:16 master and re-framing it to 4:5 and 1:1 covers the set; cropping one master to the others usually hides something that mattered.
Where are the safe zones on Instagram Reels ads?
The platform's caption, profile name and call-to-action cover the lower part of the frame and its engagement controls run down the right edge. Keep the message in the central band and confirm the current safe-zone dimensions against Meta's published documentation, which change.
Do Meta ads need captions?
In practice yes: most feed and Stories impressions start muted, so a script that only exists in the audio is unread by most viewers. Captions, an explicit first frame and on-screen product make the piece work with the sound off.
Are these specifications current?
They are a planning frame, not the platform's own specification document. Meta revises placement requirements, so the media team should verify dimensions, lengths and file limits against Meta's current documentation at upload.
