What is Flooring Calculator?
A flooring calculator estimates the amount of material needed -- tile, hardwood, laminate, or carpet -- based on room dimensions and waste factor. It helps you order the right amount, minimizing expensive returns and avoiding mid-project shortages.
How to Use
- Enter the room's length and width
- Select the flooring type (tile, hardwood, laminate, vinyl, carpet)
- Set the waste percentage (typically 10% for standard rooms, 15% for diagonal layouts)
- View the total square footage of material needed and estimated cost
Frequently Asked Questions
- How much waste should I account for?
- Add 10% for standard straight-lay patterns. Add 15% for diagonal or herringbone patterns. Complex room shapes or patterned tile may need up to 20%.
- How do I measure an irregularly shaped room?
- Break the room into rectangles and triangles, calculate each area separately, and add them together. Include closets and alcoves if they'll be floored.
- How do I convert square footage to the number of tiles?
- Divide the total square footage by the area of one tile. For 12x12-inch tiles (1 sq ft each), the number of tiles equals the square footage. For 12x24-inch tiles (2 sq ft), divide by 2.
