Formula for Calculating Bricks Needed: Patios and Walkways (Square Feet)
Calculate Square Feet
Length times Width = Square Feet
Calculate Brick Need
4.58 times Square Feet = Number of Bricks Needed

Patios: Flagstone 1.5" to 2" Thickness
Pounds/Square Foot
17 to 20 Pounds per Square Foot
Coverage Per Ton
Approximately 100/155 Square Feet per Ton
Formula
Length times Width = Square Feet
Square Feet times 20 = Pounds divided by 2,000 = Tons
Steppers: Flagstone 1.5" to 2" Thickness
Stepper Size
A normal stepper is 1 Square Foot and weighs 20 Lbs.
Calculate Need
# steppers times 20 = Pounds divided by 2,000 = Tons
