If you sell on Amazon and you're staring at a rejected creative or a blank upload field, this amazon video ad specs guide covers the dimensions, lengths, file formats, and rules that matter for Sponsored Brands video, Sponsored Display video, and Amazon DSP — plus a checklist to pass review on the first try.
Why Amazon video ad specs differ from social video specs
Most paid-social platforms have converged on vertical 9:16 full-screen video because that's how people hold their phones in a feed. Amazon's ad placements work differently. Sponsored ads often sit inside search results, product detail pages, or app banners that are built around a horizontal or square frame, not a full-screen phone experience. That's why Amazon's video specs lean widescreen and square rather than vertical, and why a video cut for TikTok or Reels usually needs to be reframed, not just re-exported, before it will fit an Amazon placement.
There's also a review layer. Amazon checks creative against its own ad policies — no fake buttons or progress bars, no claims that don't match the listing, no audio that implies something the product can't do — on top of the technical spec check. A file can be the right size and still get rejected on content grounds, so treat specs and policy as two separate checklists.
Amazon video ad specs by ad type
Amazon groups video ads into three programs, and the specs guide you need depends on which one you're running.
Sponsored Brands video
Sponsored Brands video appears in shopping results and can autoplay as shoppers scroll. It's built to work without sound, so treat the first few seconds as if the viewer has no audio: lead with the product in frame and a benefit on screen, not a voiceover-only hook. Keep the video short and single-minded — one product, one clear reason to click — since this format sits inside a crowded results page competing for a glance, not a dedicated viewing session.
Sponsored Display video
Sponsored Display video can run on Amazon pages and off-Amazon on partner apps and sites, which means it needs to look clean at smaller sizes and in less controlled placements. Because this format often runs retargeting or remarketing campaigns, it works best when it repeats the product name, a core benefit, and a visual that's recognizable even if the clip is muted or partially visible in a banner slot.
Amazon DSP video
Amazon DSP (the programmatic buying side) is where video specs open up the most. DSP can place video across websites, apps, and in some cases connected TV and streaming inventory, so the accepted aspect ratios and durations are broader than Sponsored Brands or Sponsored Display. If your DSP buy includes streaming TV placements, build with full sound design in mind — voiceover, music, and clear captions — because those placements are watched more like a TV spot than a scroll-by banner.
Amazon video ad specs guide: dimensions, length, and file type
Treat the numbers below as a working starting point, not a locked rulebook — Amazon periodically updates exact limits inside its ad console, and that's the source to check before a final render. The pattern that holds across placements:
- Aspect ratio: widescreen 16:9 is the safe default for Sponsored Brands and most DSP placements; square 1:1 is commonly supported too, especially for Sponsored Display. Vertical 9:16 is generally not a core expectation on Amazon the way it is on TikTok or Reels.
- Resolution: aim high — a 1920×1080 widescreen master (or the square equivalent) gives you room to resize down without losing quality, rather than trying to upscale a small file later.
- Duration: Sponsored formats tend to favor shorter clips, often in a roughly 6-to-45-second range depending on placement; DSP can allow longer cuts, especially for streaming inventory. Shorter is almost always the safer bet for shopping-result placements.
- File format: MP4 or MOV container with standard H.264 video and AAC audio encoding is the common accepted combination.
- File size: keep the export efficient — Amazon caps upload size, and heavy, uncompressed files are a frequent cause of failed uploads. Compress before you upload rather than relying on Amazon to do it for you.
- Captions: not always mandatory, but strongly recommended given how many placements autoplay muted. Burned-in captions protect your hook regardless of sound settings.
| Placement | Typical aspect ratio | Typical length | Sound expectation |
|---|---|---|---|
| Sponsored Brands video | 16:9 widescreen, square 1:1 common | Short, often under 45 seconds | Must work muted |
| Sponsored Display video | 16:9 or 1:1 | Short, often under 30 seconds | Must work muted |
| Amazon DSP (web/app) | 16:9 widescreen, square supported | Flexible, usually short | Design for muted-first |
| Amazon DSP (streaming/CTV) | 16:9 widescreen | Longer cuts accepted | Full sound design expected |
If you also run the same campaign on TikTok or Meta, it helps to see how length expectations compare side by side — our product video ad length for different platforms guide lines up the durations that work best across channels. And if uploads keep failing on size rather than content, the video ad file size limits for social platforms guide covers compression settings that keep quality while hitting the cap.
A pre-upload checklist for Amazon video ads
Most rejections and failed uploads trace back to a short list of repeat offenders. Run through this before you submit:
- Frame orientation matches the placement. Don't submit a vertical phone-shot clip to a widescreen slot and hope it gets letterboxed acceptably — reframe it.
- Safe margins are respected. Keep key text and product shots away from the outer edges of the frame, since some placements crop or overlay UI elements.
- Claims match the listing. Any price, discount, or feature claim shown on screen should match what's actually on the product page at the time the ad runs.
- No fake interface elements. Don't animate a play button, checkmark, or progress bar that isn't a real functioning element — this is a common policy violation, not just a style note.
- Captions are legible. If you burn in text, use a font size and contrast that reads clearly on a small phone screen, not just on your editing monitor.
- Audio is optional-friendly. Build the opening visual and on-screen text to carry the message alone, then let voiceover and music add to it rather than carry it.
- File is compressed before upload. Export at the resolution you need, then compress — don't upload a massive raw file and expect it to pass size limits.
Building once, resizing for every Amazon placement
Because Amazon's placements span widescreen, square, and occasionally other ratios, the efficient workflow is to produce one strong master video at high resolution and then crop or pad it for each placement, rather than briefing a separate shoot or edit for every ad type. The same logic applies if you're also running the ad on TikTok, Reels, or Shorts: a vertical 9:16 master for social and a widescreen or square cutdown for Amazon can come from the same creative concept, just reframed.
This is where a tool like FrameNotion fits into an Amazon workflow even though it's not built specifically for Amazon. FrameNotion takes a product link or a set of product images and has FrameNotion AI write and render a 30-second vertical video ad — hook, problem, benefit, proof, offer, call to action — complete with voiceover, music, and word-by-word captions, or silent if you prefer. Every finished ad also exports as 4:5, 1:1, and 16:9 alongside the 9:16 original, so you get a square and widescreen version ready to crop and prep for an Amazon upload without starting the edit over. A finished ad takes roughly 10 to 20 minutes, which is useful when you're testing several hooks across both social and Amazon placements at once.
FrameNotion doesn't publish ads to Amazon or any ad platform, and it doesn't track performance once an ad is live — it's a creative production tool, not a media buying or reporting platform.

Specs for other platforms if you're running video beyond Amazon
If your Amazon video ads are part of a broader paid-social plan, the spec rules change again by platform. We've broken down the equivalent details for Facebook video ads, Instagram feed video ads, Pinterest video ads, and LinkedIn video ads, so you can keep one master creative and adapt it consistently across every channel you run.
Final checklist before you launch
Before you submit an Amazon video ad for review, confirm these three things one more time: the aspect ratio matches the placement you're buying, the file size and format are within current limits shown in Amazon's console, and the video communicates its hook and offer within the first few seconds with the sound off. Those three checks catch the large majority of rejections and failed uploads before they happen.
Frequently asked questions
Does Amazon support vertical 9:16 video ads?+
Vertical video isn't the standard format across Amazon's ad placements. Most Sponsored Brands, Sponsored Display, and DSP placements expect widescreen 16:9 or square 1:1 framing, so a 9:16 social video typically needs to be reframed rather than uploaded as-is.
Can I reuse my TikTok or Instagram ad on Amazon?+
You can reuse the concept and footage, but not the raw export. Crop or pad the vertical video into a widescreen or square version, adjust the duration if needed, and double check captions and claims against Amazon's policy rules before uploading.
Does Amazon require captions or subtitles on video ads?+
Captions usually aren't strictly mandatory, but they're strongly recommended. Many Amazon placements autoplay muted, so burned-in captions protect your message regardless of the viewer's sound setting.
What happens if my video fails Amazon's spec check?+
The ad gets rejected or flagged before it can run, and you'll typically need to re-export or re-edit to fix the issue — whether that's file size, aspect ratio, or a policy violation like a fake interface element — then resubmit for review.
How long should an Amazon video ad be?+
Shorter generally performs better for shopping-result placements like Sponsored Brands and Sponsored Display, often well under the maximum allowed length. DSP placements, especially streaming or connected TV inventory, can support longer cuts if the content earns the extra time.
