Plan on 4–6 inches of loam for a new lawn — enough root zone for grass to establish deep and survive a Boston summer. Thin layers green up quickly, then struggle when July heat arrives. Rake to finish grade, firm lightly, and seed into the top inch.
What 1,000 sq ft takes
| 4" of loam | 12.3 → order 13 cubic yards |
| 6" of loam | 18.5 → order 19 cubic yards |
At bag-store volumes that's hundreds of bags, so bulk is the only sane route. Loam ships up to 6 yards per truckload — a full lawn is a multi-truck job, with dispatch sequencing the loads and volume pricing applying. Booking in late winter gets first pick of April seeding dates. Run your square footage through the material calculator, then order screened loam.
