Per Square Foot (PSF)

PSF is short for “per square foot” and is a unit of measure that we use in association with price.

Example: $1.50 psf x 200 sq.ft. = $300.00

So what is a “square foot”?

A “square foot” is a unit of area measurement equal to a square measuring one foot on each side,
see example below; 0.0929 square meters. Abbr.: ft2, sq. ft.


Using the formula above, let’s bring this all together.
Example: You have a wall on your house that is 10 feet tall by 10 feet wide. ( 10′ x 10′ )

What is the square footage of this wall?

Answer: 10′ x 10′ = 100 ft2 (100 ft2 = 100 SqFt = 100 sq.ft.)

Now if a product costs $1.50 psf (per square foot) and you need 100 sq.ft. your cost would be $150.00.

$1.50 psf x 100 sq.ft. = $150.00
