Flooring Calculator
Calculate how much flooring you need for one or more rooms, including installation waste, package quantities, leftover material, and estimated material cost.
Flooring
Measurement System
Choose the measurement system used for your room dimensions. Imperial uses feet and inches. Metric uses meters and centimeters.
Rooms
Enter each rectangular area separately. Add additional rooms for hallways, closets, alcoves, or other areas.
Waste
Flooring waste accounts for cuts, damaged material, fitting around obstacles, and installation complexity. Ten percent is a common starting point for a straightforward installation.
Pricing
Optional. Enter either a price per square foot or a price per package.

About the Flooring Calculator
Use this flooring calculator to estimate how much flooring you need for one or more rooms. Calculate floor area, installation waste, required material, package quantities, leftover flooring, and estimated material cost for common flooring products including luxury vinyl plank (LVP), vinyl plank, laminate, hardwood, engineered hardwood, bamboo, cork, tile, carpet tile, and peel-and-stick flooring.
Enter each rectangular area separately for a more accurate flooring estimate. You can use Imperial measurements in feet and inches or Metric measurements in meters and centimeters.
How to Measure a Room for Flooring
Measure the length and width of each rectangular section of the floor. For Imperial measurements, enter the length and width in feet and inches. For Metric measurements, enter the dimensions in meters and centimeters.
If a room has an irregular shape, divide it into smaller rectangular sections and enter each section as a separate room. This is especially useful for hallways, closets, alcoves, open-plan rooms, and other spaces that cannot be accurately represented by a single rectangle.
How to Calculate Flooring Square Footage
For a rectangular room, multiply the room length by the room width to calculate the floor area. When a project contains multiple rooms or rectangular sections, calculate each area separately and add the areas together.
This flooring calculator converts Imperial or Metric measurements into a consistent area calculation automatically.
How Much Extra Flooring Should I Buy?
Flooring installations normally require extra material for cutting, damaged pieces, fitting around walls and obstacles, and future repairs. A 10% waste allowance is a common starting point for a straightforward rectangular installation. More complicated layouts, diagonal installations, patterns, and rooms with many cuts may require a larger allowance.
Flooring Boxes and Package Coverage
Flooring is commonly sold in boxes, cartons, packages, bundles, or individual pieces rather than in the exact quantity required for a room. Enter the product coverage or dimensions to estimate how many packages or pieces are required after accounting for flooring waste.
Imperial and Metric Flooring Measurements
Choose Imperial when your measurements are in feet and inches. Choose Metric when your measurements are in meters and centimeters. Using the measurement system that matches your tape measure or building plans makes it easier to enter dimensions accurately and reduces conversion mistakes.
Flooring Types
Flooring requirements vary by product. LVP, vinyl plank, laminate, hardwood, engineered hardwood, bamboo, cork, tile, carpet tile, and peel-and-stick flooring may have different package sizes and coverage. Use the product information from the flooring manufacturer or retailer when entering package coverage and product dimensions.
Frequently Asked Questions
How much flooring do I need for a room?
Measure the room's length and width, calculate the floor area, and add an appropriate waste allowance. If flooring is sold by the box or package, round the required quantity up to the next complete package.
How much extra flooring should I buy?
Ten percent extra is a useful starting point for many straightforward flooring installations. Increase the waste allowance for rooms with unusual shapes, many cuts, diagonal installations, patterns, or other installation challenges.
Can I use feet and inches?
Yes. Select Imperial and enter room dimensions using feet and inches. The calculator converts the measurements into a consistent area calculation automatically.
Can I calculate flooring in meters?
Yes. Select Metric and enter room dimensions using meters and centimeters. The calculator converts the measurements for the flooring area calculation.
Should I keep leftover flooring?
Yes. Keeping matching leftover flooring can be useful for future repairs, damaged boards, broken tiles, or replacement pieces.
Does this calculator optimize flooring cuts?
No. This calculator estimates flooring quantities using room area, waste, product coverage, package quantities, and related measurements. Actual cutting requirements depend on the room layout, installation direction, pattern, seams, obstacles, and the installer.
