-
Over 70% of Amazon traffic is mobile — a 970×250 billboard built for desktop delivers nothing on a mobile detail page
-
Sponsored Display Video went globally available in 2025 — most advertisers still default to static and miss 2–3× brand awareness lift
-
Wrong dimensions aren’t rejected with an error — Amazon silently excludes your ad from placements where the size doesn’t fit
-
Prime Video pause ads are low-competition, captive-audience placements that most brands haven’t touched yet
-
DSP HTML5 creatives exceeding the 200KB initial load limit are silently rejected — the most common spec violation Epinium sees in audits
Amazon ad sizes determine more than whether your creative fits a slot. They dictate which placements you are eligible for, how the algorithm weights your ad in the auction, and whether a shopper on mobile sees your brand at all. Get the dimensions wrong and your creative either gets rejected outright or renders in a way that destroys CTR.
This guide covers every current Amazon advertising format with exact 2026 specifications — from Sponsored Products to Streaming TV — plus the file requirements that trip up most advertisers.
Why Amazon Ad Sizes Matter More Than You Think
Over 70% of Amazon traffic comes from mobile devices. A creative built for a desktop 970×250 billboard delivers nothing on a mobile detail page. Amazon ad serving will not throw an error — it just will not show your ad in placements where the size does not apply. Larger placements like 970×250 achieve 15–30% higher CTR than mid-tier sizes in the same category. But only if the creative is built for that exact canvas.

Sponsored Products: Image Quality Requirements
Sponsored Products pull assets directly from your product listing — Amazon controls the rendered ad dimensions. Your job is the main image quality:
-
Minimum 1000×1000px (1500×1500px recommended for zoom eligibility)
-
Pure white background (RGB 255,255,255) for most categories
-
Product must fill 85%+ of the image frame
-
JPEG, PNG, GIF or TIFF; JPEG preferred

Sponsored Brands Video auto-plays without sound. The first 3 seconds need to communicate the value proposition visually. Opening with a logo reveal is a reliable way to lose the viewer.

Streaming TV and Prime Video Ad Sizes
Streaming TV ads run on Prime Video, Fire TV, Freevee, Twitch, and third-party CTV apps. STV is Amazon’s fastest-growing ad channel in 2026 and is full-screen video only — no banner fallback exists for this format.
| Specification | Requirement |
|---|---|
| Dimensions | 1920×1080px (full HD required) |
| Aspect ratio | 16:9 only |
| Duration | 15 or 30 seconds (non-skippable) |
| Format | MP4 (H.264), MOV |
| Max file size | 500MB |
| Audio | AAC or PCM, 128kbps minimum, stereo required |
| Companion banner | 1920×1080px static image shown post-ad on Fire TV |
Prime Video pause ads require a static 1920×1080px JPEG or PNG, max 2MB. This placement reaches viewers at a low-distraction moment. CPMs are higher than standard display but attention quality justifies the premium for upper-funnel campaigns.
Audio Ad Specs
| Specification | Requirement |
|---|---|
| Duration | 10–30 seconds |

The Formats Most Advertisers Skip in 2026
-
Sponsored Display Video: Now globally available. Most advertisers still default to static. Video in this format drives 2–3× more brand awareness lift in Amazon’s own studies.
-
Prime Video pause ads: Captive audience, low competition. The pause moment is low-distraction and the format is still relatively uncrowded compared to standard display.
-
970×250 billboard in DSP: Most advertisers build 300×250 and skip the billboard entirely. A dedicated 970×250 asset opens placements that expand reach without touching budget.
Amazon Ad Sizes in 2025–2026: What Actually Changed
Sponsored Display Video Went Global (Q1 2025)
Before 2025, Sponsored Display Video was limited to select markets and advertisers. The global rollout in Q1 2025 opened the format to all Amazon advertisers with video assets. Most brands haven’t updated their creative workflows yet — which means the format is under-competitive relative to its performance data. Amazon’s own measurement studies show 2–3× higher brand awareness lift for video vs. static in this placement. The first-mover window is still open.
Prime Video Pause Ads Opened to Broader Advertiser Access (2025)
Amazon initially restricted Prime Video pause ads to large DSP budgets. Throughout 2025, Amazon expanded access to a wider range of advertisers. The format shows a full 1920×1080 static image when a viewer pauses content — a captive moment with no competing visual elements. CPMs run higher than standard display, but the attention quality at a pause moment is measurably different from a banner on a shopping page. For upper-funnel brand campaigns, this format is underpriced relative to its impact.
Vertical 9:16 Video Format Added to DSP (2025)
DSP now accepts 1080×1920px (9:16) vertical video alongside the standard 16:9 horizontal format. This matters because Amazon’s mobile app renders vertical video natively in certain placements — the same asset also repurposes for off-Amazon programmatic inventory on mobile. Brands already producing 9:16 for TikTok and Instagram Reels can reuse those assets in DSP without reformatting, which cuts creative production costs while opening new Amazon placements.
Epinium data
Brands running creative compliance checks through Epinium’s asset validator catch an average of 4.3 spec violations per campaign before upload. The two most common: DSP HTML5 creatives exceeding the 200KB initial load limit (silently rejected — no error shown) and 970×250 billboard assets submitted at 728×90 dimensions (renders at wrong aspect ratio in all billboard placements).

Maintaining spec-compliant creatives across 10+ ad formats, multiple ASINs, and several marketplaces is an automation problem. Epinium validates creative assets against current Amazon specs, flags compliance issues before upload, and tracks performance by format and placement so you can cut spend on underperforming sizes and scale what works.

FAQ: Amazon Ad Sizes
What are the most important Amazon ad sizes to prioritize?
Start with 300×250 (covers most mobile and desktop placements), 320×50 (mobile banner essential), and 970×250 (desktop billboard — missed by most advertisers). For video, 1920×1080px at 16:9 covers Sponsored Brands Video, Sponsored Display Video, and STV. Build those five assets and you cover 90% of available Amazon inventory.
What happens if I submit a creative with wrong dimensions?
Two outcomes depending on format. Sponsored Brands and STV run active rejection — your ad will not be approved and you’ll see an error in Campaign Manager. DSP and Sponsored Display handle it differently: the ad may be approved but silently excluded from placements where the dimensions don’t match. You’ll see impressions drop without any error flag. This is the most dangerous failure mode because it looks like a budget or bid problem, not a creative problem.
Can I use the same creative for Sponsored Brands and DSP?
For static images, partially. A 1200×628px Sponsored Brands banner is not the same as the 970×250 DSP billboard — they’re different aspect ratios and render at different sizes. For video, a 1920×1080px 16:9 asset will technically meet both format requirements, but DSP video has different duration limits (up to 3 min vs. 45s for Sponsored Brands). Build format-specific assets for anything beyond basic awareness campaigns.
What Amazon ad size gets the highest CTR?
970×250 (desktop billboard) achieves the highest CTR in most categories — 15–30% above mid-tier sizes. The trade-off: it’s desktop-only. On mobile, 300×250 drives the most volume because it’s the primary placement on detail pages. The highest overall campaign performance comes from running both, not choosing between them.
Do I need different ad sizes for mobile and desktop?
Yes. Mobile primary placements are 300×250, 320×50, and 414×125. Desktop primary placements are 728×90, 970×250, and 300×600. A campaign running only 970×250 delivers nothing on mobile. A campaign running only 300×250 misses the highest-CTR desktop placements. Run both size sets from campaign launch.
What is the minimum budget to run Amazon DSP?
Self-service DSP through Amazon requires a minimum of $10,000/month. Managed service (through Amazon’s own team) starts at $35,000/month. Some Amazon agencies offer DSP access at lower minimums through their own seats — these are legitimate options for brands that want DSP reach without the managed service floor.
Are Amazon video ads worth the production cost?
For Sponsored Brands Video, yes for almost any active advertiser — Amazon provides the creative canvas and the performance data clearly shows video outperforms static in most categories. For STV, the math depends on your average order value and category. High-AOV categories (electronics, appliances, premium consumables) see strong ROAS on STV. Low-AOV impulse categories see worse returns because the CPM is too high relative to the purchase value.
What is the file size limit for Amazon ad images?
It depends on format. Sponsored Brands and Sponsored Display static images: 1MB (logo) and 2MB (banner). DSP display: 2MB. DSP HTML5: 200KB initial load, 2.2MB total. Alexa home screen background: 450KB. Fire Tablet lock screen: 1MB. The DSP HTML5 200KB initial load limit catches most advertisers — a complex HTML5 unit that loads fine in a browser will hit that limit and be silently rejected in DSP.
