The best aspect ratio for Pinterest video ads is 2:3 (vertical), which Pinterest treats as its default shape for standard video Pins. A square 1:1 video is a safe second choice that holds up well across most placements, and a taller 9:16 works for full-screen formats like Idea Pin ads. Horizontal 16:9 is supported but tends to display smaller in the feed, so treat it as a last resort rather than your main format.
Why aspect ratio matters so much on Pinterest
Pinterest's feed is a vertical, masonry-style grid, not a single full-width stream like a TikTok or Reels feed. That means the shape of your video changes how much space it occupies on screen, how it sits next to other Pins, and whether Pinterest adds bars or crops your frame to fit the layout.
A video built for the wrong ratio usually survives — Pinterest will still play it — but it loses the parts of the frame that matter most. Logos get clipped, subtitles run off the bottom, and product shots that were centered for a horizontal frame end up squeezed into a tall column with awkward empty space on the sides.
Getting the aspect ratio for Pinterest video ads right up front avoids all of that. It also means your video takes up more of the visible feed, which gives it a better shot at being noticed before a viewer scrolls past.
Pinterest video ad aspect ratios explained
Pinterest supports a handful of shapes, but they are not interchangeable. Each one is built for a specific placement or use case.
| Aspect ratio | Shape | Where it works best | Trade-off to know |
|---|---|---|---|
| 2:3 | Vertical | Pinterest's default for standard video Pins and most video ad placements | Slightly shorter than 9:16, but displays fully without cropping in most feed placements |
| 1:1 | Square | Catalog-style product videos and campaigns running across several platforms | Uses less vertical screen space than 2:3 or 9:16, so it reads smaller in a tall feed |
| 9:16 | Full vertical | Idea Pin-style and full-screen mobile placements | Can get cropped or framed with bars if the placement is actually built around 2:3 |
| 16:9 | Horizontal | Reused landscape footage, webinars, or ads built primarily for desktop or YouTube | Shows up noticeably smaller in Pinterest's vertical grid, limiting how much screen it fills |
If you want the exact dimensions and file requirements behind each of these shapes, it's worth checking a dedicated breakdown of Pinterest promoted video specs so you're not guessing at pixel sizes or file limits before you upload.
How to choose the right ratio for your campaign
Rather than picking one ratio for everything, match the shape to the placement you're actually buying.
- Standard video ad in the main feed: default to 2:3. It's the native shape Pinterest designs the feed around, and it shows fully without Pinterest having to crop or pad it.
- Idea Pin-style or full-screen ad: use 9:16. These placements are built to fill the whole mobile screen, closer to what you'd use for a TikTok or Reels ad.
- Catalog or product-focused video running alongside static product Pins: 1:1 keeps visual consistency with square product images and still reads cleanly at a glance.
- Repurposed landscape content (a webinar clip, a brand video built for YouTube): use 16:9 only when you don't have a vertical or square version available, and treat it as a stopgap rather than your main creative.
If you're running the same campaign idea across Pinterest, TikTok and Meta, don't start from a single master file and hope it crops well everywhere. A short framework for choosing aspect ratio across multiple platforms can save you from building five near-identical videos by hand.
Vertical is the safer default, even outside Idea Pins
Because Pinterest's whole layout favors tall shapes, a vertical video — whether 2:3 or 9:16 — almost always occupies more visible feed space than a square or horizontal one. If you can only produce one version of an ad, make it vertical.
Common aspect ratio mistakes to avoid
- Uploading a 16:9 video as your primary creative and letting Pinterest shrink it to fit a tall feed, losing most of the visual impact.
- Placing your logo, offer text or call to action right at the edge of the frame, where different placements are likely to crop it.
- Reusing a square Instagram feed video for Pinterest without checking whether the specific ad unit is actually built for 2:3 or 9:16.
- Designing one aspect ratio and assuming it will "auto-adjust" cleanly for every Pinterest ad format — placements vary, and a video that looks right in one can look cramped or cropped in another.
- Ignoring safe margins for captions, since word-by-word or burned-in captions near the bottom can get cut off in some crops.
A simple checklist before you upload
- Confirm the exact placement you're buying (standard video Pin vs. Idea Pin-style) and match the aspect ratio to it.
- Keep your logo, headline and call to action inside a safe center zone, away from the top and bottom edges.
- Export a vertical version (2:3 or 9:16) as your primary file, and keep a square 1:1 backup for placements that call for it.
- Double-check your video length against Pinterest's guidance — a short guide to Pinterest video ad length is useful if you're unsure how long to make the cut.
- Preview the ad at actual mobile size before launch, not just on a desktop editor, since cropping differences are much easier to spot on a phone screen.
How FrameNotion fits into this
If you're building the video itself from scratch, aspect ratio shouldn't be the part that slows you down. FrameNotion lets you paste a product or website link, and FrameNotion AI writes a custom 30-second video ad — hook, problem, benefit, proof, offer and call to action — then renders it as a 9:16 vertical MP4 at 1080×1920.
Because Pinterest ad placements don't all use the same shape, every FrameNotion ad also comes with 4:5, 1:1 and 16:9 versions automatically, so you have a square cut ready for catalog-style placements and a vertical cut ready for full-screen ones without re-editing anything by hand. You can also add your logo, up to six product images, and notes like a promo code, and choose a voiceover, music, sound effects and captions, or keep it silent so the ad still works on mute.
A finished ad takes about 10 to 20 minutes, and the first one is free when you sign up. After that, plans start from a Starter tier on the pricing page if you need more ads or want to run A/B hook variants. Note that FrameNotion builds the video itself — it doesn't publish directly to Pinterest or any other ad platform, so you'll still upload the finished file through Pinterest's own ad manager.
Bringing it together
There isn't a single universal aspect ratio for Pinterest video ads — but there is a clear default. Build your primary creative in 2:3, keep a 9:16 version ready for full-screen placements, and fall back to 1:1 or 16:9 only when the placement calls for it. Get the shape right first, then focus your energy on the hook and the offer, since that's what actually earns the watch.
Frequently asked questions
Can I use the same video file for Pinterest and TikTok ads?+
You can, but check the shape first. TikTok is built around full-screen 9:16, while Pinterest's standard video Pins default to 2:3. A 9:16 video will usually still display on Pinterest, but a file cut specifically for 2:3 will look more native in the main feed.
What happens if my video's aspect ratio doesn't match Pinterest's spec?+
Pinterest will typically still play the video, but it may add padding bars, crop the edges, or shrink the video within the feed card. None of these outcomes are ideal, which is why matching the ratio to the placement upfront is worth the extra step.
Is vertical video required for Pinterest video ads?+
It's not strictly required, since square and horizontal formats are supported, but vertical shapes (2:3 or 9:16) make better use of Pinterest's tall feed layout and generally take up more visible space on a phone screen.
Should Idea Pin ads use a different aspect ratio than standard video ads?+
Idea Pin-style and full-screen placements are typically designed around 9:16, closer to a story or short-form video shape, while standard video Pins default to 2:3. Match your export to the specific ad unit you're buying rather than using one ratio everywhere.
Does a square video work for Pinterest shopping or catalog ads?+
Yes. A 1:1 square video reads well next to static product images in catalog-style feeds and rarely gets cropped awkwardly, even if it doesn't fill as much vertical space as a 2:3 or 9:16 video.
