Lawn Watering Calculator
Calculate how long you need to water your lawn for optimal growth. Determine watering times based on lawn size, sprinkler type, soil conditions, and local weather factors.
Step 1: Lawn Specifications
Understanding Lawn Watering Needs
Most lawns need 1-1.5 inches of water per week. Sandy soils require more frequent watering, while clay soils hold moisture longer and need less frequent watering.
Step 2: Watering Parameters
About Watering Efficiency
Watering efficiency accounts for evaporation, wind drift, and uneven coverage. Higher efficiency means more water reaches the roots. Early morning watering typically has the highest efficiency.

Watering Time Formula
Watering Time (minutes) = (Area × Water Needed × 0.623) / (Flow Rate × Efficiency)
To calculate watering time: Multiply lawn area by water requirement, convert to gallons (×0.623), then divide by the product of sprinkler flow rate and watering efficiency (as a decimal).
