What is Flooring Calculator?

Calculates total square footage and retail cartons needed for hardwood, laminate, vinyl plank, or carpet installations.

How to Use This Calculator

  1. Enter room length and width in feet.
  2. Set waste buffer.
  3. Review square footage and cartons needed.

The Mathematical Formula & Variables

Total Sq Ft = Length * Width * (1 + Waste / 100); Cartons = ceil(Total Sq Ft / Box Coverage)

Step-by-Step Worked Example

Scenario: 25 ft by 14 ft room with 10% waste buffer and 20 sq ft cartons.

  1. Net floor area = 25 * 14 = 350 sq ft.
  2. Add 10% waste: 350 * 1.10 = 385 sq ft.
  3. Cartons needed = 385 / 20 = 19.25 -> round up to 20 cartons.

Result: 385.00 Sq Ft (20 Cartons)

Frequently Asked Questions

Should I keep leftover cartons after installation?
