Help and setup
Prepare your variants, then check the calculator in your store before offering it to shoppers.
Configure your rolls
In Walltally, choose a product and variant. Enter width, length, unit, pattern match, allowances, spare rolls and identical rolls per unit sold.
Confirm pack sizes with the supplier: “double roll” does not always mean two physical rolls. Keep samples disabled.
Save and add the block
Save settings and wait for confirmation. If a conflict occurs or a save is uncertain, reload the product before trying again.
The setup link opens the Shopify theme editor. Add Walltally to a product page and save your theme. Adding the block and publishing the theme remain your choice.
Check the estimate and cart
Test several walls and the units you offer. Compare dimensions with the manufacturer’s specifications and check the cart quantity, especially for packs.
The method uses whole drops and rolls. Doors and windows are included; offcuts are not reused between different cut heights. Offset matching adds one full repeat per drop. Have this method confirmed for your wallpaper.
If the calculator is missing
Check the block, variant activation and settings, and the Shopify plan. Missing or invalid settings, an unconfirmed or expired plan and unsupported products can hide the calculator.
Unavailable plan verification can also hide it. Authorized staff can still view settings or disable a variant. Contact support with the domain and steps observed, without passwords or tokens.
