Facebook Feed
The default surface for 4:5 ad creatives. The image holds its full width in the scroll and leaves the primary text and headline below it untouched.

1080×1350 Ad Creatives (4:5 Meta Feed)
1080×1350 is the tall 4:5 ad creative size, the largest crop Meta allows in the feed. It takes more vertical room in the scroll than a square does, and Rapid Ads renders it natively at 1080×1350 from one line of text rather than stretching the square version to fit.

Placement map
Where 1080×1350 ad creatives render
4:5 is what most buyers run against 1:1 on the same concept, because the taller frame occupies more of the screen on the way past. One 1080×1350 file is eligible across the feed surfaces below.
Instagram Feed
A 4:5 creative fills the post frame edge to edge. Nothing is letterboxed and no white bars appear beside your ads.
Instagram Explore
Explore renders a dense grid of ad creatives, so the same 1080×1350 file drops in without a second export.
Facebook video feeds
Static ad creatives are served between video units, so a 1080×1350 file out of Rapid Ads keeps delivery going in a placement most buyers forget to fill.
Facebook Reels feed
The in-feed reels surfaces still render static ad creatives, and a 1080×1350 file is tall enough to hold the scroll without being cut back to a square.
Audience Network
Off-platform inventory takes the 4:5 creative happily, extending the reach of one generated ad beyond Meta's own apps.

Meta revises its ad specs regularly. Rapid Ads renders at the recommended resolution, which stays valid through minor spec changes because it is the largest size the placement asks for.
The crop trap
Why a resized crop gets rejected or letterboxed
Stretching a square up to 1080×1350 is the fastest way to lose a test. The product sits off-centre, the offer text drifts into a margin, and the ad still spends. Rapid Ads composes inside the portrait frame from the start, so nothing has to be rescued after the fact.
Cropped from a master
Offer text falls outside the frame
The headline sat in a margin the portrait crop threw away, so the ad runs with half a word on screen.
Copy cut offLetterbox bars around the creative
An upscaled or padded file leaves grey bands around the ad, and it reads as an accident rather than a design.
Bars on every impressionSoft, upscaled pixels
Below 600 × 750 px the review flow warns you, and the placement still serves the blurry file to your audience.
Quality warningComposed at 1080×1350
The frame is the brief
Rapid Ads composes inside the portrait frame from the start, so the offer text lands where the placement will show it.
Nothing clippedFull-bleed in every surface
The file is already at the 4:5 the placement wants, so no bars and no automatic re-crop are applied to your ads.
Edge to edgeNative pixels, not upscaled ones
Every creative is rendered at 1080×1350, well clear of the 600 × 750 px minimum the reviewer checks.

1080×1350 questions
What media buyers ask about this format before they run it.
1080×1350 pixels. That is the recommended resolution for the portrait 4:5 placement; the accepted minimum is 600 × 750 px, but ads served at the minimum look soft next to everything else in the feed. Rapid Ads always renders the full 1080×1350.
You can upload it everywhere, but the placements built around a different shape will pad or crop it. Generate the same description at the other ratios as well and one concept covers all of them without a design pass.
No. The generator on this page is free to use and needs no sign-up and no ad account. It is rate-limited so it stays fast for everyone; if you hit the limit, wait a moment and generate again.
Yes. Write it into the description — for example “bold text: 30% OFF” — and it is rendered into the ad creative at the placement's real pixel size rather than pasted over a crop.
Neither wins outright — 4:5 takes more of the screen, 1:1 is eligible in more surfaces. Generate the same description at both in Rapid Ads and let the ad set tell you which one your audience stops on.
