Here are some simple formulations to calculate how much product you will need. Or if you prefer, simply contact us and we will be happy to assist you.

Squares & Rectangles

• Area: Length x Width = Square Feet (sq. ft.)
(Example: Length = 6', Width = 4'. 6' x 4' = 24 sq.ft.)

• Depth: Inches Deep ÷ 12 = Decimal Depth.
(Example: Depth = 3"/12 = .25)

• Cubic Feet: Area x Decimal Depth = Cubic Feet (cu. ft.)
(Example: 24 sq.ft. x .25 = 6 cu.ft.)

• Tons Needed: Weight per Cubic Foot x Cubic Feet needed.
(Example: Product = 100 lbs. per cubic foot. 6 cubic feet needed.
100 x 6 = 600 lbs. ÷ 2000 = .3 Tons)

• Yards Needed: Cubic Feet ÷ 27.
(Example: 6 cu.ft./27 = .22 Cu. Yds. (Cubic Yards) or 1/4 Cu. Yd.

Circles

• Area: Diameter x .7854 = Square Feet (sq. ft.)
(Example: Diameter =12' x 12' x .7854 = 113.1 sq.ft.)

• Circumference: Diameter x 3.1416. = Linear Feet
(Example: Diameter = 12' x 3.1416 = 37.7 Linear Feet.
Please note: Circumference is the running feet around the border of a circle.)

Tidbits

• A ton of most loose stone products cover roughly 80 sq.ft., 3" deep.

• A yard always covers 108 sq.ft., 3" deep.

• Always figure compaction for areas over 6" deep. Compaction for sand and soil is about 15 to 20%. On most products a ton is equal to 75% of a cubic yard.
