Order sod a few days before installation — it begins to degrade quickly once rolled.

How to Use This Lawn Calculator

  1. Measure your lawn in feet (subtract beds, patios and the house footprint).
  2. Enter the sod coverage per pallet from your supplier.
  3. Pick the seeding purpose that matches your project.

The calculator multiplies length × width for the area, divides by the pallet coverage, and applies the seeding rate in pounds per 1,000 square feet.

Sod Pallet Coverage and Weight

Sod pallets are not standardized. Coverage is typically 400–500 square feet, but a pallet can weigh anywhere from 1,500 to 3,000 pounds depending on soil moisture. Always confirm the coverage and weight with your sod farm, because delivery trucks and trailers have limits.

Installation tip: sod is perishable. Install it within 24–48 hours of delivery, stagger the seams like brickwork, and water heavily in the first week.

Grass Seed Rates

Project Rate per 1,000 sq ft Example: 1,000 sq ft lawn
New lawn~5 lb5 lb
Overseeding~3 lb3 lb
Dense / athletic~8 lb8 lb

Different grass species — fescue, ryegrass, bluegrass, Bermuda — have different seeding rates. The seed bag always lists the exact rate; use the "Other" situation as a guide and check the label.

Frequently Asked Questions

How many pallets of sod do I need for 2,000 square feet?

How much grass seed do I need for 1,000 square feet?

A new lawn usually needs about 5 pounds per 1,000 square feet, while overseeding an existing lawn takes about 3 pounds per 1,000 square feet.

How many square feet does a pallet of sod cover?

Most sod pallets cover 400–500 square feet and weigh 1,500–3,000 pounds. Check the exact coverage with your local sod farm before ordering.

Is sod or grass seed cheaper?

Grass seed is much cheaper per square foot, but requires weeks of careful watering and may need a second pass in bare spots. Sod costs more but gives an instant, uniform lawn.
