Calculating the Square Footage

If you like, you may send or bring in your plans and we will do the calculations for you.

Remember, oddly shaped rooms can be broken down into multiple sections. In case you've forgotten your high school geometry (who hasn't!), there are some formulas in the right column. We suggest adding 15% onto the area of a triangle or sector because of the additional waste of cutting on an angle or curve.

If a measurement includes inches, don't forget to convert them to a decimal before you multiply! There are 12 inches in a foot, so for example 3 inches becomes 3/12 = 1/4 = .25 feet.

## Sample Floorplan

See below for an example of how you could measure an oddly shaped space.

Room Description Species/Grade Space # Width Length Square Footage
Living Room Select Maple 1 24 24 576
2 6 8 48
3 16 8 128

Subtotal 752
Waste Factor 75
TOTAL 824

## Formulas

### Feet & Inches

1 foot = 12 inches
1 inch = 1/12 feet ≈ .083 feet

Area = L • W

### Triangle

Area* = W • H / 2

### Sector

Area* = π • R • R • A / 2
π ≈ 3.14159265

* We recommend adding 15% onto the actual area of triangles and sectors because of the additional waste of cutting on an angle
