How to Measure Your Turf Area:

Easy mathematics can take a lot of the guesswork out of measuring your turf area. Use any of the following formulas and diagrams to meet your yard or layout.

CIRCULAR AREA
A = 3.14 x R2

Example: Circle's radius (r) is 10 feet. Multiply the known 3.14 by the radius squared, thus:
A = 3.14 x 102
A = 3.14 x 100
A = 314 square feet

SQUARE/RECTANGLE AREA
A = Base x Height

Example: 'B'ase is 10 feet, and the 'H'eight is 10 feet, thus:
A = 10' x 10'
A = 100 square feet

TRIANGULAR AREA
A = (Base x Height)
2

Example: 'B'ase is 10 feet, and the 'H'eight (base to point) is 20 feet, thus:
A = 10' x 20' A = 200
2 2

A = 100 square feet

COMBINATION FREE-FORM & BREAKDOWN TO FORMS
Break the free-form area to obvious forms and calculate each form's area. Once each form is calculated, add the areas together to derive a total area.

1 - 3.14 x R2

2 - b' x h'

3 - b' x h'
