Sod
Standard sod pieces are about 16 × 24 in or 2 × 5 ft (10 sq ft); a pallet typically covers 400–500 sq ft depending on the farm. Add about 5% for cutting around beds and curves.
Example: 2,000 sq ft + 5% = 2,100 sq ft → 210 pieces, or 5 pallets at 450 sq ft.
Grass seed rates
Seeding rates vary a lot by species. Typical new-lawn rates per 1,000 sq ft: tall fescue about 6–8 lb, Kentucky bluegrass 2–3 lb, perennial ryegrass 5–10 lb, bermudagrass (hulled) 1–2 lb. Overseeding uses roughly half. Follow the rate on the seed bag.
Timing
Cool-season grasses establish best in early fall; warm-season grasses in late spring to early summer. Keep new sod or seed consistently moist for the first 2–3 weeks.
