Flooring Calculator
Calculate how much flooring you need for a room, including extra for waste and cuts.
A 10% waste allowance is typical for straight layouts. Use 15-20% for diagonal or patterned installations.
What is Flooring Calculator?
A flooring calculator works out how much flooring material you need for a room, based on its length and width plus an allowance for waste from cuts and mistakes. It is used for tiles, laminate, vinyl, hardwood and carpet.
Buying exactly the room area is rarely enough — cuts at edges, doorways and pattern matching all consume extra material. Adding a waste allowance of 10-15% is standard practice.
How does the Flooring Calculator work?
The room area is length times width in square feet, the standard unit for flooring in India.
The waste allowance adds a percentage on top — 10% for straight layouts, 15-20% for diagonal or patterned installations.

- Enter the room length and width in feet.
- Set the waste allowance using the slider — 10% is typical.

Frequently Asked Questions
How much extra flooring should I buy?
10% extra is standard for straight layouts. Use 15-20% for diagonal installations, patterned tiles, or rooms with many corners and doorways.
Does the calculator work for tiles?
Yes. The total area in square feet tells you how much tile area to buy. Divide by the coverage per box (printed on the box) to get the number of boxes.
What if my room is not a rectangle?
Split the room into rectangles, calculate each one, and add them together. Add a slightly higher waste allowance for irregular shapes.
