Flooring guides
Short, practical answers to go with the calculators.
How to measure a room for flooring
Measure a rectangle, split an irregular room, and keep the purchase plan honest.
How many boxes of flooring do I need?
Turn square footage into cartons, see how waste and whole-box rounding add up, and avoid a short order.
How much flooring waste should I add?
Choose an allowance with room geometry, cuts, seams, and installation patterns in mind.
How to measure a room for carpet
Why carpet is ordered by roll width, where seams go, and how to convert to square yards.
How to measure stairs for carpet
Measure treads, risers, and nosing wrap, handle landings and winders, and turn it into a carpet order.
Common questions
Which flooring calculator should I use?
Use the flooring calculator for anything sold in cartons (laminate, vinyl plank, engineered and solid hardwood) and the carpet calculator for roll goods.
How much extra flooring should I buy?
It depends on the layout and room shape. Straight lays in rectangular rooms need less than diagonal or patterned layouts. Use the product’s installation guidance.
Why does carpet need more than the floor area?
Carpet comes in fixed roll widths, so you buy full-width strips and pay for the offcut beyond the room width.
