TL;DR
- Stack: Shopify + POD vendor (Printful/Printify; Gelato for international) + PIMW Product Personalizer.
- Types: fleece (entry), sherpa (premium, plush back), woven (heirloom/graphic).
- Make-or-break: validate photo upload at 300 DPI against the largest size, blankets magnify low-res badly.
- Method: sublimation for fleece/sherpa full-color; woven is created from the weave.
- Pricing: $40-120+ by type/size; collage add-ons via Cart Transform; ~45-55% margin.
5-step setup
- Add blanket products. In your POD vendor, create products per type and size, set print area, push SKUs to Shopify.
- Install PIMW Product Personalizer. From the Shopify App Store.
- Add type & size selectors. Type (fleece/sherpa/woven) and size (baby/throw/queen) via conditional logic with per-option pricing.
- Build the upload canvas with strict DPI validation. Photo upload + optional collage and text, validating 300 DPI at the largest size.
- Set pricing and test. Cart Transform type/size + add-ons; draft order; verify line item properties.
Blanket types
| Type | Look & method | Position |
|---|---|---|
| Fleece | Soft, lightweight, sublimation full-color edge to edge | Entry / most popular |
| Sherpa | Printed fleece front + plush sherpa back | Premium upgrade |
| Woven (tapestry) | Image formed from the weave; textured, heirloom | Keepsake; graphic/limited-color designs |
Offer fleece as entry, sherpa as premium, woven for keepsakes. Confirm types/sizes with your vendor. Method detail: sublimation guide.
The resolution rule (most important step)
Blankets are among the largest POD products, so a phone photo that looks fine on screen will be obviously blurry across a queen blanket. Aim for 300 DPI at the final size. Large throws and queens need a very high pixel count, so many customer photos only suit smaller sizes. Validate the upload against the largest size the customer can select (not a thumbnail) and warn or block low-res before checkout. PIMW Product Personalizer enforces DPI validation against the chosen size and supports HEIC, catching problems before production. For collages, each photo must meet the requirement for its placement area. Full reference: POD print file specs.
Pixel math, collage layouts, and memorial blankets
The math is simple: required pixels = blanket size in inches x DPI. Check the exact dimensions with your vendor, since sizes vary.
- 50x60 in at 300 DPI: 15,000 x 18,000 px. Even at 200 DPI it is 10,000 x 12,000 px.
- 60x80 in at 200 DPI: 12,000 x 16,000 px.
- A typical 12 MP phone photo is 4032 x 3024 px, which works out to well under 100 DPI across a 50x60 throw.
That is why the size selector and the DPI check have to talk to each other. One workable rule: warn below roughly 75% of the target and block below 50%, so borderline photos still sell on smaller sizes while clearly blurry ones never reach production.
For collages, offer a short set of layouts rather than a free-form canvas: 2 photos side by side, 3 in a row, a 2x2 grid, a 6-photo layout, and a hero photo with 4 thumbnails as the premium option. Each slot is smaller than the full blanket, so smaller photos can still work there.
Memorial blankets (a photo, name, birth and passing dates, and a short line of text) sell year-round and deserve a careful flow: suggested text such as "In Loving Memory of" or "Always in Our Hearts", separate date fields so the format stays consistent, restrained templates, and an optional border or frame.
Pricing & margin
| Type / size | Example price |
|---|---|
| Fleece throw | $50 |
| Sherpa throw | $80 |
| Queen sherpa | $120 |
| Collage / text overlay | +$5-10 |
| Margin after POD cost | ~45-55% |
Blankets have strong gifting demand: memorial, family, baby, wedding, and pet keepsakes. Push larger sizes, the sherpa upgrade, and collage layouts to lift AOV. Strong for Christmas and Mother's Day.

Frequently asked questions
How do I let customers design custom photo blankets on Shopify?
Install a personalizer like PIMW Product Personalizer on your product page. The customer picks a blanket type and size, uploads one or more photos (optionally adding text or a collage), and sees a live preview before adding to cart. Choices save as Shopify line item properties your POD vendor uses. Create blanket products per type and size, push to Shopify, build a Personalizer with type/size selectors plus a photo upload validating 300 DPI at the largest size, then test with a draft order. No code; ~40 minutes. Because blankets are large, strict resolution validation is the most important part.
What blanket types can you print on demand?
Common POD blanket types are fleece, sherpa, and woven. Fleece is most popular and affordable, soft, lightweight, printed edge to edge with vivid full-color photos via sublimation. Sherpa has a printed fleece front and plush sherpa back, a premium upgrade. Woven (tapestry/jacquard) creates the image from the weave rather than surface printing, giving an heirloom, textured look better for graphic/limited-color designs than detailed photos. Offer fleece as entry, sherpa as premium, woven for keepsakes. Confirm types and sizes with your vendor.
What resolution do photos need for a custom blanket?
Blankets are among the largest POD products, so resolution is critical, a low-res photo fine on a phone will be obviously blurry across a queen blanket. Aim for 300 DPI at the final size; large throws and queens need a very high pixel count, so most phone photos suit only smaller sizes. Validate the upload against the largest selectable size, not a thumbnail, and warn/block low-res before checkout. PIMW Product Personalizer enforces DPI validation against the chosen size and supports HEIC, catching problems before production. For collages, each photo must meet the requirement for its placement area.
How much should I charge for a custom blanket?
Custom photo blankets are premium-priced. In 2026 they commonly retail from ~$40 for a small fleece up to $90-120+ for a large sherpa. Price by type and size: fleece throw $50, sherpa throw $80, queen sherpa $120, with collage/text add-ons via Cart Transform. After POD cost ($25-55 by size/type), margin runs ~45-55%. Blankets have very strong gifting demand, memorial, family, baby, wedding, pet keepsakes, and high perceived value, so emphasize larger sizes, the sherpa upgrade, and collage layouts to lift AOV.
Which POD vendor is best for custom blankets?
Printful and Printify both offer custom fleece and sherpa blankets with sublimation and good integration; Printify often has more variety and lower cost across providers, Printful more consistent quality. Gelato is worth considering for international shipping since blankets are bulky and benefit from local production to cut shipping cost and damage risk. Woven/tapestry blankets may need a specialty provider. Confirm types, sizes, and print quality and sample, since softness and color vary by vendor. PIMW Product Personalizer is vendor-agnostic, so one blanket designer works across whichever vendor or mix fits your range and geography.
Can customers make a photo collage blanket?
Yes. With PIMW Product Personalizer, the blanket designer can offer multi-photo collage layouts alongside a single full-bleed photo, letting customers arrange several images into a grid or template and add names, dates, or a message, ideal for family, memorial, and anniversary keepsakes. Each photo is validated for resolution against its placement area so the result stays crisp, and everything renders on a live preview at the selected size before checkout. The composed layout and photo URLs are stored in line item properties for your vendor. Collage and text options raise conversion and AOV, since a multi-photo memory blanket is far more personal and giftable than a single image.
Is PIMW Product Personalizer free to install?
Yes. PIMW Product Personalizer is free to install from the Shopify App Store. The Free plan includes 1 personalizer template on up to 2 personalized products; paid plans (Basic $7.99, Pro $13.99, Unlimited $24.99 per month, each with a 3-day free trial) raise the template, step, and product assignment limits. Every plan includes unlimited custom orders with no per-order fees. There is no upfront fee and no credit card required to install.
How long does PIMW Product Personalizer take to set up?
Most stores set up their first personalized product in under 15 minutes. The Shopify App Store install takes about 60 seconds; adding text fields, photo upload, color swatches, and live preview to a product takes 5-10 minutes. Catalog-wide rollout (50+ products) uses bulk-apply templates and typically takes 30-60 minutes total.
Does PIMW Product Personalizer work with Shopify Basic, Shopify, Advanced, and Shopify Plus?
Yes. PIMW Product Personalizer works on every Shopify plan including Basic, Shopify, Advanced, Plus, and Shopify Starter. The core personalization fields, live preview, and order capture work on every tier.
Does PIMW Product Personalizer slow down my Shopify store?
No. PIMW Product Personalizer uses Shopify's storefront block architecture, which loads only on personalized product pages and doesn't add render-blocking scripts site-wide.
Does PIMW Product Personalizer work with Printful, Printify, Gelato, and other POD partners?
Yes. PIMW Product Personalizer writes the customer's personalization to standard Shopify line item properties, which Printful, Printify, Gelato, and other major print-on-demand apps read. The data flows through Shopify's standard order pipeline, so any partner that reads line-item properties (which all major POD apps do) receives it with the order.
Does PIMW Product Personalizer support Shopify Markets, multiple currencies, and multiple languages?
Yes. Field labels translate per language, upcharge prices can be set per currency, and the personalizer fully supports right-to-left languages including Arabic and Hebrew. The personalizer also handles Unicode for Cyrillic, CJK (Chinese/Japanese/Korean), Greek, and accented Latin characters with appropriate font fallback.
