A 24 × 18 ft lawn takes 36 linear ft of 15 ft turf, two 18 ft pieces, and 1,080 to 1,512 lb of infill at Envirofill's 2.5 to 3.5 lb per sq ft for a 1 1/2 to 1 3/4 in pile.
A worked example
A side yard 31 ft long and 13 1/2 ft wide in a 2 in landscape turf needs 31 linear ft of 15 ft turf. 13 1/2 ft fits inside one 15 ft width, so a single 31 ft piece with no seam; across the yard it would take 3 pieces of 13 1/2 ft, 40.5 ft. Infill at 3.5 to 4.5 lb per sq ft over 418.5 sq ft: 1,465 to 1,883 lb.
How much infill per square foot of artificial turf?
Envirofill's chart goes by pile height: 1.5 to 2.5 lb per sq ft for 1 to 1 1/4 in pet or playground turf, 2.5 to 3.5 lb for 1 1/2 to 1 3/4 in landscape turf and 3.5 to 4.5 lb for 1 7/8 to 2 1/4 in. Synthetic Grass Warehouse lists 1.5 to 2.5 lb for its 1.5 and 1.625 in landscape turf.
How wide are artificial turf rolls?
15 ft wide and 100 ft long on Synthetic Grass Warehouse's spec sheets. A lawn up to 15 ft across goes in one piece with no seam; at 18 ft it takes two, so the direction the pieces run decides how many linear feet you buy.
What else it is called

Turf and infill by lawn size
| Lawn, length × width | Linear ft of 15 ft turf | Pieces and seams | Infill, lb (1 1/2 to 1 3/4 in pile) |
|---|---|---|---|
| 10 × 10 ft | 10 | 1 × 10 ft, no seams | 250-350 |
| 15 × 12 ft | 12 | 1 × 12 ft, no seams | 450-630 |
| 20 × 15 ft | 20 | 1 × 20 ft, no seams | 750-1,050 |
| 24 × 18 ft | 36 | 2 × 18 ft, 1 seam | 1,080-1,512 |
| 30 × 20 ft | 40 | 2 × 20 ft, 1 seam | 1,500-2,100 |
| 40 × 25 ft | 75 | 3 × 25 ft, 2 seams | 2,500-3,500 |
| 50 × 30 ft | 100 | 2 × 50 ft, 1 seam | 3,750-5,250 |
Rolls 15 ft wide and 100 ft long (Synthetic Grass Warehouse spec sheets), laid in the direction that buys the fewest linear feet. Infill at 2.5 to 3.5 lb per sq ft of lawn, Envirofill's rate for 1 1/2 to 1 3/4 in landscape turf.
Where the numbers come from
- Rolls and infill on the turf spec sheets of Synthetic Grass Warehouse, Catalina and TigerTurf Majestic (REV112425): «Width: 15 Feet Length: 100 Feet» and particulate infill «1.5-2.5 Lbs Per Sq Ft» for a pile of about 1.50 and 1.625 inches. Read October 26, 2026. SGW Catalina spec sheet (PDF)
- Infill by pile height: Envirofill Installation Guidelines for landscape and recreational applications, depth and quantity chart: 1 to 1 1/4 in pet and playground turf 1.5 to 2.5 lb per sq ft, 1 1/2 to 1 3/4 in landscape 2.5 to 3.5 lb, 1 7/8 to 2 1/4 in landscape 3.5 to 4.5 lb; material loss «less than 1% if installed properly». Envirofill installation guidelines (PDF)
- The rest is arithmetic: pieces = lawn width ÷ roll width rounded up, laid along the length, or the other way round, whichever buys fewer linear feet; seams = pieces − 1; infill = lawn sq ft × the rate, not the turf bought.
Turf is cut from the roll in whole widths, so the linear feet buy more than the lawn: 540 sq ft for a 432 sq ft lawn here, trimmed off at the edges. The base under the turf and the nails along the seams are not counted.
