Inchworth adds a price calculator to your product pages for anything sold by size: curtains, blinds, banners, glass, fabric, frames and printed goods. Customers type their width and height, choose options, and see the price and a drawing of their size update as they go. At checkout, Inchworth works the price out again from your own rule, so the amount charged always matches your pricing. Start from a template, adjust every price and size, and match the calculator to your store's colours.

• Price by area, length, perimeter, volume, per item or your own price table
• Options that change the price: swatches, photos, dropdowns, counts and text
• Live price and size drawing on the product page, on desktop and mobile
