You have already done the hard part. The product is photographed, the background is clean, the listing is live. Then you decide to run paid traffic to it and discover that the images which look perfect on your Shopee or Shopify listing get awkwardly cropped, softened or buried under the interface once Meta puts them in front of a real person.
Meta ads are not the same problem as marketplace listings. A marketplace shows your image in a predictable square tile. Meta shows the same asset across a dozen placements, each with its own shape and its own overlays. This guide covers the dimensions that matter in 2026, the safe zones you need to respect, and how to prepare a small set of assets that covers almost all delivery without shooting anything twice.
The two ratios that do most of the work
Meta's placement list is long, but delivery is concentrated. If you produce assets at two sizes, you cover roughly 90 per cent of where your ads actually appear:
- 1080 x 1080 px (1:1) — square, safe everywhere. Feed, carousel, right column, marketplace, search results.
- 1080 x 1920 px (9:16) — full-screen vertical. Stories and Reels on both Facebook and Instagram.
There is a third worth adding once you have those two: 1080 x 1350 px (4:5). This is the tallest ratio the mobile feed renders without cropping, so it occupies more vertical screen space than a square does. For feed-heavy campaigns, 4:5 is the better master format and 1:1 becomes the fallback.
Placement specifications at a glance
| Placement | Aspect ratio | Recommended pixels | Notes |
|---|---|---|---|
| Facebook and Instagram feed | 4:5 or 1:1 | 1080 x 1350 or 1080 x 1080 | 4:5 takes more screen height on mobile |
| Stories and Reels (all four surfaces) | 9:16 | 1080 x 1920 | Unified safe zone since March 2026 |
| Carousel | 1:1 | 1080 x 1080 | Every card must match; mixed ratios are not supported |
| Right column and search | 1:1 | 1080 x 1080 | Rendered small; avoid fine detail |
| Catalogue and Advantage+ feed images | 1:1 preferred | 1024 x 1024 or larger | Meta's hard floor is only 500 x 500 |
File requirements are generous compared with most marketplaces: JPG or PNG, up to 30 MB for ad creative. That does not mean you should upload a 25 MB file. Meta re-encodes everything it serves, so an oversized upload buys you nothing and simply slows your workflow. A well-compressed JPG at 200 to 500 KB is plenty at 1080 px.
Safe zones: the part most sellers get wrong
Vertical placements overlay your creative with a profile name, caption, call-to-action button, and on Reels a stack of interaction icons down the right-hand side. If your product sits dead centre on a 9:16 canvas by default, the bottom of it will frequently be hidden behind the CTA.
As of March 2026, Meta consolidated Facebook Stories, Facebook Reels, Instagram Stories and Instagram Reels into a single unified 9:16 safe zone, which means one correctly designed vertical asset now works across all four without UI obstruction. That is genuinely good news — it used to take separate versions.
Working on a 1080 x 1920 canvas, keep your product, logo and any text inside these margins:
- Top: roughly 14 per cent, about 270 px
- Bottom: 20 to 35 per cent, about 380 to 670 px depending on the CTA used
- Left and right: roughly 6 per cent, about 65 px each
In practice that leaves you a usable band in the upper-middle of the frame. Compose for it deliberately rather than centring and hoping. The background can and should extend to the full canvas edge, so the ad still feels full-bleed; it is only the subject and text that need to sit inside the safe band.
What happened to the 20 per cent text rule
Meta removed the hard 20 per cent text overlay limit several years ago, along with the old text overlay checking tool. Ads with heavy text are no longer penalised in the auction or blocked from delivery.
The performance advice survived the policy change, however. Images with less than roughly 20 per cent text still tend to outperform text-heavy ones, largely because dense text is unreadable at the size a feed image is actually viewed. If you are adding a price flash or a discount badge, keep it to a handful of large words rather than a paragraph.
One important exception: catalogue and Advantage+ feed images follow a different rule set. Product images pulled from your catalogue should be clean, accurate representations of the product. Text overlays, promotional badges and watermarks on catalogue images can trigger rejections and, at minimum, look wrong when Meta composites them into a dynamic template that already adds its own price and title.
Preparing your marketplace photos for Meta
Most sellers already have a library of square, white-background product images sized for a marketplace. You do not need a new shoot; you need a resizing and re-composition step.
Square to vertical
Do not stretch. Place the square product image onto a 1080 x 1920 canvas, positioned so the product sits in the upper-middle safe band, then fill the remaining space with a solid colour or soft gradient drawn from your brand palette. This reads as a designed ad rather than a stretched listing photo, and it takes seconds per image once you have the template.
Square to 4:5
This is a gentler change. Extend the canvas vertically and let the product breathe, or crop in slightly if the original has generous margins. Avoid cropping so tight that the product touches the frame edge — Meta's own preview thumbnails will make it look cramped.
Batch the whole thing
If you are advertising more than a couple of products, doing this by hand in an image editor will consume your afternoon. A batch resizing tool such as PixelPrep lets you push a folder of listing images through the 1:1, 4:5 and 9:16 outputs in one pass, with consistent padding and compression, so all your creative comes out matching rather than approximately similar.
Catalogue image quality is a conversion lever
For Advantage+ catalogue and dynamic product ads, the image comes from your product feed, not from your creative folder. Meta's stated minimum is 500 x 500 px, but that floor is far too low in practice. At 500 px your product will look soft the moment it is rendered on a modern phone screen, and it gives Meta no headroom to crop for different placements.
Target 1024 x 1024 px or larger, square, JPG or PNG, under 8 MB. Cropping problems in catalogue ads are overwhelmingly caused by source images that are too small or not square to begin with, and Meta consistently reports materially better conversion performance for catalogues with high-quality photography.
Check that every product in your feed has at least one image, and that the image matches the variant being advertised. A dynamic ad that shows the black version of a product while the landing page defaults to white is a quiet but persistent conversion leak.
A pre-launch checklist
- Export three sizes per creative: 1080 x 1080, 1080 x 1350 and 1080 x 1920.
- On the vertical asset, confirm the product and any text sit clear of the top 14 per cent, bottom 35 per cent and 6 per cent side margins.
- Keep file sizes sensible — under 1 MB per image is ample at these dimensions.
- Use JPG for photographic product shots; reserve PNG for graphics with hard edges or genuine transparency.
- Make every carousel card exactly 1:1 at identical pixel dimensions.
- Keep text overlays large, short and outside the safe-zone margins.
- Strip promotional badges and watermarks from catalogue feed images.
- Audit your feed for any product image below 1024 x 1024 px and re-export it.
- Preview in Ads Manager across placements before publishing, not after.
The underlying principle is simple: your marketplace images were composed for a tile, and Meta ads are composed for a screen. Build the templates once, batch everything through them, and the creative side of your ad account stops being a recurring chore.
