Lawn Area Calculator: Area of any lawn shape

How do I measure a lawn?

Sketch the lawn and split it into rectangles.

Measure the length and width of each rectangle and enter them as sections.

Measure any patio, bed or path inside the lawn and enter it to subtract.

For curved edges, use the average width of the section.

Lawn area = section 1 + section 2 + section 3 − areas to subtract

A back lawn 50 ft by 30 ft plus a side strip 20 ft by 15 ft, minus a 100 ft² patio: 1,500 + 300 − 100 = 1,700 ft².

Sod Area + 5%, in 2.67 ft² slabs or 1 m² rolls

Grass seed About 5 lb per 1,000 ft² (25 g/m²) for a new lawn

Fertilizer Based on pounds of nitrogen per 1,000 ft²

Watering About 1 in (25 mm) a week in summer

For exact figures, take your area to the sod, lawn seed, fertilizer or irrigation calculator.
