Calculate flooring square footage from room length and width, multiple rooms, or known area. Estimate flooring boxes, underlayment, waste, baseboard, trim, and project cost.
Single room mode:
The calculator multiplies room length by room width and subtracts any excluded area.
Multiple rooms mode:
The calculator multiplies one room area by the number of same-size rooms.
Known area mode:
The calculator starts from your known flooring area and estimates waste, boxes, underlayment, trim, and cost.
Room with closet mode:
The calculator adds the closet or extra area to the main room before calculating materials.
A flooring area calculator helps estimate square footage for hardwood, laminate, vinyl plank, tile, carpet, engineered wood, and other flooring projects.
It can help calculate net flooring area, material area with waste, flooring boxes, underlayment rolls, trim length, labor cost, and estimated project cost.
Your result shows gross flooring area, excluded area, net flooring area, area with waste, boxes or rolls needed, underlayment rolls, trim length, transition length, and estimated cost.
Multiply the room length by the room width. For example, a 12 foot by 10 foot room has 120 square feet of flooring area.
Many flooring projects use 5% to 10% extra for simple layouts. Tile, diagonal layouts, herringbone, irregular rooms, and pattern matching may need 10% to 15% or more.
Yes, if flooring will not go under them. Use the excluded area field for cabinets, islands, built-ins, closets you are not flooring, or other areas to subtract.
Divide the area with waste by the coverage per box or roll, then round up to the next whole box or roll.
No. It is an estimate. Actual flooring needs vary by layout, cuts, plank or tile size, room shape, thresholds, transitions, stairs, pattern, waste, and installer method.
