How it works

  1. 1

    Measure

    Enter the dimensions you can actually take with a tape measure. The diagram on each page shows exactly what to measure.

  2. 2

    Read the four answers

    Raw quantity, buyable cartons, sundries you would otherwise forget, and a realistic budget band for your region.

  3. 3

    Print and go

    Every result prints as a clean shopping list. Take it to the counter instead of trying to remember numbers in the aisle.

Why these calculators are different

A quantity is not a purchasing decision. Contractors lose money on three things that a bare calculator never mentions: waste allowance, packaging increments (you cannot buy 2.4 boxes), and the sundries nobody budgets for — thinset, grout, spacers, screws, sanding discs, blades.

Every page here outputs a four-part answer: the raw quantity, the buyable quantity (rounded to real package sizes), a shopping list with the sundries included, and a low/mid/high budget range. That is the difference between a number and a purchase plan.
