Coverage Calc adds a calculator to product pages for items sold by coverage, such as tile, flooring, paint, turf and soil. Shoppers type their room dimensions, the calculator adds your waste percentage, converts the total into your sales unit and rounds up. It shows the estimated cost and adds the exact quantity to the cart in one click. You set coverage, waste and minimum quantity per product or variant from the Shopify admin.

• Turn room dimensions into boxes, cans, bags or rolls with waste included
• Add the exact quantity to cart in one click, with the estimated cost shown
• Set up a whole collection at once; meters or feet, English or Spanish
