Lawn Watering Calculator: Run Times and Water Use

Pick your head type, lawn size and season to see run times, gallons per week and a simple watering schedule.

These tools give planning-level estimates from typical values and the details you enter. They are not quotes, designs or engineering, and results depend on your actual yard, soil, water pressure and flow, system condition, weather and local rules. Only a site visit can confirm what a project needs, and we give you a written scope and price before any work begins.

How it works

Four quick steps.

  1. 01

    Pick the head type

    Spray, rotor or drip, each applies water at its own rate.

  2. 02

    Enter the area

    Square feet of lawn or bed in the zone.

  3. 03

    Choose the season

    Spring, summer or fall changes how much water plants need.

  4. 04

    Read the schedule

    Run times, gallons per week and a simple watering plan.

Tips

  • Water deeply and less often, early in the morning.
  • Use cycle and soak on slopes and clay, so water sinks in instead of running off.
  • A catch-cup test shows what your own zones really apply.
Questions

About this tool.

How long should I run my sprinklers?

It depends on head type, soil and season. The calculator gives a starting point, which you can fine-tune with a catch-cup test.

How much water does a lawn need?

Many lawns do well with about an inch a week in season, from rain and irrigation together.

Why does the tool use typical rates?

Every head differs, so it uses common application rates. A water audit measures yours.

Is this a quote or a rule?

Neither. It is a planning estimate. Local watering restrictions may apply, so check yours.
