How does WallpaperCalc know how many rolls a customer needs?

The customer enters wall width and height in centimetres or inches, and the app calculates the rolls or panels required from the coverage settings you define per product. No manual maths on either side.

Does it work for wall panels or only wallpaper rolls?

Both. You can price per roll or per unit, so wallpaper rolls and wall panels run side by side in the same store.

Is there a free plan?

Yes. WallpaperCalc has a free plan, so you can install it from the Shopify App Store and test it on your products before paying anything.

Will it actually reduce returns?

Wrong quantity is the main reason wallpaper comes back. When customers calculate the exact number of rolls before ordering, they stop over-buying to be safe and stop under-buying and hitting dye batch mismatches on reorder.

About this

WallpaperCalc is a Shopify app that calculates exactly how much wallpaper or wall panelling a customer needs before they buy. The shopper enters wall width and height, in centimetres or inches, and the app returns the number of rolls or panels required for that product. It removes the single most expensive mistake in wallpaper ecommerce: wrong quantities. Order too few rolls and the reorder may come from a different dye batch that does not match on the wall. Order too many and the extras come back as returns. We built it at Curtains Calculator UAB in Lithuania as a sister app to our Curtain and Blind Calculator, after retailers we work with through InterioApp kept asking for the same instant-answer logic for wall coverings. Each product carries its own coverage settings, so a narrow designer roll and a large wall panel calculate correctly side by side in the same store. It is for wallpaper brands, wall panel sellers and interior stores on Shopify that lose sales when customers hesitate at "how many rolls do I need?" and lose margin when they guess wrong. There is a free plan, installation takes minutes from the Shopify App Store, and the app carries the Built for Shopify badge for performance and integration standards.
