POD Image Specs 2026: One Table, Five Vendors

Every POD spec article online covers one vendor at a time. That’s useful if you sell on one platform. It’s useless the moment you list the same design on Printful, Printify, Redbubble, Amazon Merch on Demand, and Etsy, because the file that passes one vendor’s checker fails another’s for reasons that aren’t obvious from the upload screen.

This is the cross-vendor table. Every figure was pulled from the vendor’s own help docs and verified on May 10, 2026. POD specs drift — Printify quietly raised SVG limits last year, Amazon Merch tightened its file-size cap, Redbubble pushed its absolute pixel ceiling higher. Date-stamp anything you reuse from this page; the numbers below are the ones live today.

The pod image specs table (verified 2026-05-10)

Three things jump out the moment you put the numbers side by side:

• Etsy is the loosest. It cares about a 2000 px minimum, not DPI. If you only sell on Etsy, you can ship designs other vendors would reject.
• Amazon Merch is the strictest. Fixed 4500×5400 px, 300 DPI, 25 MB cap. The 25 MB ceiling is the killer — a transparent PNG at full Merch dimensions routinely lands at 30–60 MB before optimization.
• Redbubble has the highest pixel ceiling. 13500×13500 px is roughly 9× Amazon Merch’s pixel area. If your art ever needs to print on a duvet cover or a 36-inch poster, you design for Redbubble first and downsample everywhere else.

Printful (verified 2026-05-10)

Printful’s docs publish a 150 DPI minimum for garments and 300 DPI for paper goods, with a 200 MB file size cap — the most generous of any vendor on this list. Their system runs uploads through a Smart Image Tool that auto-upscales below-spec files, but the output is visibly softer than a native-res file. For Printful specifically, the constraint that bites in practice is the embroidery 6-color limit, not the image spec.

Printify (verified 2026-05-10)

Printify recommends 300 DPI for apparel, mugs, and posters; 120–150 DPI for blankets and leggings. The 100 MB cap on PNG/JPEG and 20 MB on SVG is the lowest published pixel-format cap of the five vendors. Printify also runs uploads through Claid.ai’s auto-enhancement when files come in under spec — useful, but their own docs note “limitations to the level of improvement that can be achieved.” Translation: it works on a 250-DPI file. It won’t save a 72-DPI file scaled up in Photoshop.

Full pixel-by-product breakdown lives in the Printify image requirements guide.

Redbubble (verified 2026-05-10)

Redbubble publishes the most aggressive pixel ceiling of the five — 9075×6201 px standard, 13500×13500 px absolute maximum, per their image dimensions help article. They accept JPEG, PNG, and static GIF. There’s no single published file size cap; the practical bottleneck is the upload-time tile generator, which struggles on files that exceed a few hundred MB even when pixel dimensions are legal.

If you’re producing art for the largest possible product (duvet covers, throw blankets, oversize wall prints), Redbubble is the vendor whose spec dictates your master file size. Design at 13500×13500 once, export down for the other four.

Amazon Merch on Demand (verified 2026-05-10)

Amazon Merch publishes a fixed 4500×5400 px / 300 DPI / 25 MB spec for standard apparel, per their content policies and quality requirements. PNG with transparency is required. The 25 MB file size cap is what catches most sellers — a clean transparent PNG at full Merch dimensions with detailed art frequently exports to 30–60 MB. The fix is PNG-8 conversion or selective lossy compression with TinyPNG before upload.

Merch’s quality bar is the strictest in another way: rejected designs hurt your tier eligibility. There’s no Smart Image Tool fallback. Files either pass or they don’t.

Etsy (verified 2026-05-10)

Etsy’s spec is the outlier. There’s no DPI requirement at all — Etsy isn’t printing your design, it’s hosting your listing. Per Etsy’s seller image requirements, the rule is 2000 px minimum on the shortest side for listing photos. Format: JPG, PNG, or static GIF.

For sellers who use Etsy as a storefront and a separate fulfillment vendor (Printify, Printful, Gelato, etc.), the design specs that matter are the fulfillment vendor’s, not Etsy’s. Etsy only controls how your listing photos look in search.

The one-file-five-vendors test

Take a 6000×6000 px, 300 DPI design exported as a transparent PNG at roughly 35 MB — a reasonable master file for serious POD work. What happens when you upload that exact file to all five?

• Printful: Accepts. Well under the 200 MB cap.
• Printify: Accepts. 35 MB sits inside the 100 MB PNG cap.
• Redbubble: Accepts. 6000 px is below the 9075×6201 standard ceiling.
• Amazon Merch: Rejects on file size. 35 MB exceeds the 25 MB cap. Compress to PNG-8 or run through TinyPNG.
• Etsy: Accepts as a listing photo. 6000 px clears the 2000 px minimum easily.

The bottleneck is always Amazon Merch’s 25 MB ceiling. Every other vendor is lenient enough that a single well-prepared master file sails through. Build your workflow around Merch’s cap and the other four become free passes.

Frequently Asked Questions

What DPI do POD vendors require in 2026?

300 DPI is the safe default across Printify, Amazon Merch on Demand, and Redbubble for apparel and most accessories. Printful accepts 150 DPI as a minimum on garments but recommends 300 DPI for paper goods. Etsy has no DPI requirement at all — its 2000 px minimum applies to listing photos, not fulfillment files (verified May 2026).

Which POD vendor has the largest file size limit?

Printful, at 200 MB per upload, per its official help center. Printify caps PNG and JPEG at 100 MB and SVG at 20 MB. Amazon Merch on Demand has the strictest cap at 25 MB. Redbubble doesn’t publish a single number; the pixel ceiling (13500×13500) is the binding constraint there (verified May 2026).

Can I use the same design file across Printful, Printify, Redbubble, Amazon Merch, and Etsy?

Almost — the bottleneck is Amazon Merch’s 25 MB cap. A 6000×6000 px transparent PNG at typical export quality lands in the 30–60 MB range, which Merch will reject. Compress through PNG-8 conversion or TinyPNG to land under 25 MB and the same file works on the other four vendors.

Does Printify auto-enhance low-resolution images?

Yes. Printify runs uploads through Claid.ai for automatic enhancement, per its design guide. The system has limits — it can rescue mildly under-spec files but not 72 DPI screen graphics scaled up. Design at native pixel dimensions and treat auto-enhancement as a backstop, not a workflow.

What’s Redbubble’s maximum image size?

Redbubble’s standard pixel ceiling is 9075×6201 px, with an absolute maximum of 13500×13500 px on its largest products, per its image dimensions help article. That’s roughly 9× the pixel area Amazon Merch on Demand allows on standard apparel. If your art has to scale to duvet covers or oversize wall prints, design at the Redbubble maximum and downsample for everything else (verified May 2026).
