Order = area · (1 + waste/100).

Compute the total square-feet of hardwood flooring to order for a room: multiply length × width to get the floor area, then add 5-15 % waste for cuts. Recommended waste factor: 5-7 % straight-board layout, 10 % diagonal layout, 15 % herringbone or chevron. Reports raw area, waste sqft, total order, and number of 20-sqft cartons.
