Measure the actual project area
For sprinkler runtime, measure the beds, lawn, border, container, or planting area instead of relying on a rough visual estimate.

Sprinkler Runtime Calculator
Estimate sprinkler runtime from desired water depth and measured application rate.
Enter your garden or yard measurements
Measure the actual area, depth, spacing, quantity, or product coverage that applies to the project. The sprinkler runtime tool converts those inputs into practical planning quantities.
Important: Use the inputs that match your situation. Results are estimates based on the values and assumptions entered.

Guidance
Account for depth, spacing, and packaging
A square foot measurement alone may not be enough. Material depth, plant spacing, bag size, coverage rate, and reasonable waste can materially change what you need to buy.
Use the product label for application rates
For seed, fertilizer, soil amendments, or treatment products, enter the coverage or application rate from the specific product label. The calculator should not replace label directions.

How to use it
Start with the values requested by the Sprinkler Runtime tool and replace any sample numbers with figures from your actual situation. Estimate sprinkler runtime from desired water depth and measured application rate. Keep every entry in the unit and time period shown beside the field, then review the highlighted result together with the supporting outputs.
What the results mean
The highlighted result is the main answer produced by the Sprinkler Runtime calculation. The additional result cards provide context, components, ratios, costs, quantities, or comparison values that help explain why the primary result changed when you adjusted an input.
How the calculation works
The Sprinkler Runtime tool applies the arithmetic or modeling relationship described by the requested inputs and supporting outputs. Estimate sprinkler runtime from desired water depth and measured application rate. Keep units, rates, and time periods consistent so the result reflects the scenario you intended to model.
Example and practical context
Measure the project once for the exact mathematical quantity, then run it again with a reasonable waste or coverage allowance. That comparison helps you see the difference between the installed quantity and what you may actually need to purchase.
