Flooring Calculator

Spike's Calculators

This calculator can be used for any kind of flooring that is sold by the box including hardwood, laminate, vinyl, cork and bamboo flooring. It will estimate the amount flooring needed based on Sq. Ft / Box coverage.

Example:
Box of flooring covers 22.45 square feet a box
Room length= 10'
Room width = 10'
Square foot of room = 10' * 10' = 100 sq. ft.
Amount of boxes needed for this room = 4.45 boxes
Total result of boxes = 5 (rounded up from 4.45 boxes)

What happens if you add a waste factor to this example.

If you add a waste factor to this example of 10%, the total result of boxes including waste needed stays the same as the result for total boxes needed.

Example:
waste factor = 10%
it takes the amount of boxes needed of 4.45 and adds 10 % to this = 4.9
Total result of boxes = 5 
Total result of boxes including waste = 5 

In this example the 10 % waste was included in the amount of extra flooring you have because you buy the amount of flooring needed by the full box and both results will be the same.

Now if you were to add a waste factor to this example of 15%, the total result of boxes including waste needed will increase from the result for total boxes needed

Example:
waste factor = 15%
it takes the amount of boxes needed of 4.45 and adds 15% to this = 5.12
Total result of boxes = 5
Total result of boxes including waste factor = 6

Keep in mind that the amount of boxes needed to cover an area, you buy by the box, will include more than you need in most cases.


Sq Ft/Box must be entered.
