Summary
Cuttable generates ads in up to four aspect ratios — 1:1, 4:5, 9:16, and (on supported designs) 16:9. This article covers what each ratio is for and what happens to them when you publish or download.
Supported ratios
1:1 (Square)
4:5 (Vertical feed)
9:16 (Full vertical)
16:9 (Horizontal) — available on a limited number of ad designs, with more being added over time
Why each ratio matters
1:1 (Square)
Commonly used across Facebook and Instagram feeds.
Displays consistently across devices and placements.
Useful for broad delivery where placement flexibility is required.
4:5 (Vertical feed)
Optimised for Facebook and Instagram feed placements.
Takes up more vertical screen space than 1:1, increasing on-screen presence while remaining feed-compatible.
Widely recommended by Meta for feed-based ads.
9:16 (Full vertical)
Designed for immersive placements such as Instagram Stories, Reels, and Facebook Stories.
Matches the natural orientation of mobile devices.
Maximizes screen coverage in vertical-first placements.
16:9 (Horizontal)
Matches the standard horizontal format used by YouTube and Google Display ads.
Why don't I see 16:9 on every ad?
16:9 support is being rolled out design by design. If a specific ad's design doesn't have a 16:9 layout yet, you won't see it as an option — this is expanding over time.
What happens to each ratio when you publish or download
Ratios are generated together for a design and can't be removed or deselected individually.
Publishing directly to Meta: only 1:1, 4:5, and 9:16 are sent to your Meta campaign. 16:9 is never used for direct Meta publishing — if its layout doesn't suit your design, you don't need to fix or remove it, since it won't affect what's sent to Meta.
Downloading an ad: all generated ratios are included, including 16:9 where available. 16:9 is intended for channels that need a horizontal format, such as YouTube or Google Display. Cuttable doesn't have a direct publishing integration for those platforms yet, so download the ad and upload the 16:9 file yourself.
If the layout for any ratio doesn't look right, edit that specific ratio and adjust the elements — use Review (Shift + R) to check every ratio before publishing.
How to view each ratio when editing your ads
Select Edit ad in the top-right corner of your ad.
In the top-left corner, select an individual ratio to view it, or select Review (Shift + R) to check every ratio before publishing.
Important
Using the correct ratio helps prevent unwanted cropping or scaling in Meta placements.
Meta may automatically adjust creatives if the selected ratio does not match the placement requirements.
