What is lawn square footage?

Lawn square footage is the total grass area for sod, seed, or fertilizer planning. Measure length × width and subtract walkways and garden beds. For overall property area, use the yard calculator.

1 ft² = 144 in² 1 ft 1 ft (12 in)

Getting started

How to Calculate Lawn Square Footage

To calculate lawn square footage, measure length × width of grass areas in feet. Subtract walkways, garden beds, pools, and other non-grass features. One sod pallet covers 450-500 sq ft. One bag of grass seed covers 1,000-5,000 sq ft.

1. Measure lawn area

Measure length × width of grass areas in feet.

2. Subtract non-lawn zones

Subtract walkways, garden beds, pools, and patios from total area.

3. Plan sod or seed

Sod pallet covers 450-500 sq ft. Seed bag covers 1,000-5,000 sq ft per label.

Quick reference

Reference

1 acre = 43,560 square feet
1 square yard = 9 square feet
1 square meter = 10.764 square feet
1 square inch = 0.00064516 square feet
Area: 300 ft² × Price: $2.80 / sq ft Total: $840.00 estimated material cost

Material pricing

Calculate Cost of Materials

Sod costs $0.30-0.85 per sq ft installed. Grass seed costs $40-150 per bag covering 1,000-5,000 sq ft. Multiply lawn area by price per unit for total cost.

There are 2 steps to calculate material cost:

  1. For sod, enter price per pallet and coverage per pallet (typically 450-500 sq ft).
  2. The Square Foot Calculator divides lawn area by pallet coverage and multiplies by pallet price for material total.

Buy 5% extra sod or seed to cover edges and patches.

FAQ

Frequently Asked Questions

How do I calculate my lawn size in square feet?

Measure yard length and width in feet, multiply together, then subtract the house, driveway, and garden bed areas. A 100x60 ft yard minus a 1,500 sq ft house footprint and 400 sq ft driveway = 4,100 sq ft of lawn.

How much grass seed do I need per square foot?

Most grass seed needs 2-4 lbs per 1,000 sq ft for new lawns and 1-2 lbs per 1,000 sq ft for overseeding. A 5,000 sq ft lawn needs 10-20 lbs of seed for a new installation.

How much fertilizer do I need for my lawn?

Most fertilizers cover 5,000-15,000 sq ft per bag. Check the bag label for coverage area and divide your lawn square footage by that number to determine how many bags to buy.

How many square feet is a typical lawn?

The average American lawn is about 5,000-10,000 square feet. Small urban yards may be 1,000-3,000 sq ft, while suburban lots often have 8,000-15,000 sq ft of grass.

How do I calculate sod for my lawn?

Calculate lawn area in square feet and order 5% extra sod for waste. Sod is sold in rolls (typically 9 sq ft each) or pallets (450 sq ft). A 5,000 sq ft lawn needs about 556 rolls or 11.7 pallets.

How do I convert lawn square feet to acres?

Divide square feet by 43,560 to get acres. A 10,000 sq ft lawn is 0.23 acres. A quarter-acre lot (10,890 sq ft) is a common suburban yard size.
