Artificial Grass Calculator for Professional Installers

What makes this different from other turf calculators

If you've used an online turf calculator before, you've probably seen this: enter your square footage, pick a turf type, and get a cost estimate. Those tools work for homeowners shopping around. They don't work for installers who need to know how many rolls to order and how to cut them.

TurfBrain starts where those calculators stop. Instead of area-based math, it uses polygon-based geometry — you draw the actual yard shape, with cutouts, curves, and irregular edges — and calculates the strip layout that fits your rolls with the least waste.

The result isn't a square footage estimate. It's a dimensioned cut list, a complete material takeoff, and a job cost that includes every line item from base rock to bender board.

What the calculator covers

Turf rolls: How many rolls you need, what length to order, and exactly where each strip goes on the yard. Not “500 square feet plus 15% waste” — the actual pieces, with measurements.

Base material: Tons of DG or Class II road base with compaction factor included. The calculator uses the formula sq ft ÷ 100 × 1.4 for standard 3-inch compacted base — not the simplified area × depth ÷ 27 formula that comes up short by 30-40%.

Infill: Pounds of silica sand, zeolite, or your preferred infill product, calculated from the turf area at your specified rate per square foot.

Seam materials: Linear feet of seam tape and number of adhesive tubes, calculated from the actual seam lines in your strip layout — not a flat estimate.

Edging and accessories: Bender board by linear foot based on perimeter measurement. Landscape staples by box count. Weed barrier by square foot.

Job cost and margin: Every material line item multiplied by your custom unit prices, plus labor, plus overhead. You see your cost, your selling price, and your margin on every job.

Why installers switch from spreadsheet calculators

Spreadsheets handle the math. They don't handle the geometry. A spreadsheet can tell you that 500 square feet of turf at $3/sf costs $1,500. What it can't tell you is whether that 500 square feet needs two rolls or three, how much of each roll becomes waste, or where the seams should go.

That gap between “how much turf” and “how to cut the turf” is where most material waste happens. Installers who switch from spreadsheet-based estimating to strip-level calculation typically see waste drop from 20-30% to 10-15% — that's hundreds of dollars per job.

Try it on your next job

The best way to see the difference is to estimate a job you've already quoted. Draw the shape, run the optimizer, and compare the strip layout and material quantities to what you calculated by hand. Most installers see the gap on the first try.
