How to use it

Measure every flooring area

  1. Add each rectangular room.
  2. Subtract openings or no-floor zones.
  3. Enter the waste allowance selected for the installation.
  4. Use coverage from the exact product package.
  5. Optionally enter price and currency.

Method

From net area to whole boxes

The TypeScript Calculator Core totals included rectangles, subtracts exclusions, applies only the entered waste, and rounds purchase coverage up to whole boxes.

  • No product coverage or waste percentage is invented.
  • Required and purchased coverage remain separate.
  • Optional money uses integer minor units.
