How to check this list before buyingMatch the room and the box
The room count repeats the entered area for equally sized rooms. For different room sizes, enter their combined area and select one room. Box coverage must match the product you will buy.
The initial 10% waste is a planning allowance. Adjust it for your layout and product instructions. Whole-box rounding can add further surplus. Underlayment uses a separate allowance, if required; confirm compatibility and roll coverage before purchasing it.
