Artificial turf calculator

Enter the area you're covering and the roll width your supplier sells. You'll get the square feet to order, the length of roll, and how much infill to spread.

An area wider than one roll needs a seam. Lay the rolls in the direction that gives the fewest seams.

Plan the seams first

Turf comes in long rolls, usually 15 or 12 feet wide. If your area is 14 feet wide, a single 15 foot roll covers it with no seams. If it's 20 feet wide, you'll need two strips joined with a seam. Seams are the hardest part to make invisible, so choose the roll width and direction that give the fewest.

How the math works

Area plus the extra percentage is what you order, and dividing by the roll width gives the length of roll. A 30 by 20 foot yard is 600 square feet, or 660 with 10% extra. On a 15 foot roll, that's 44 feet of turf. At 1.5 pounds of infill per square foot, it needs about 900 pounds of infill.

What is infill for?

Infill is sand or rubber granules brushed down between the blades. It holds the turf in place, helps the blades stand up, and protects the backing from sunlight. Pet owners often use special infill that resists odors.

Common questions

What goes under artificial turf?

A base of 3 to 4 inches of compacted crushed rock or decomposed granite, often with weed barrier fabric beneath it. A smooth, firm base is what keeps the finished lawn from showing dips and ripples.

Which way should the blades face?

Turf has a grain, like carpet. Lay every strip with the blades leaning the same way, ideally toward the house or the main viewing spot, so the color looks even.
