Measure the wet footprint of your irrigation. Switch methods, units, and overlaps for accuracy better. See results instantly, then export them for your records.
| Scenario | Method | Inputs | Overlap | Wetted Area |
|---|---|---|---|---|
| Front lawn zone | Sprinkler | Radius 6 m, Arc 360° | 1.00 | 113.10 m² |
| Vegetable bed line | Strip | Length 10 m, Width 0.6 m | 1.10 | 6.60 m² |
| Single shrub | Emitter | Known radius 0.45 m | 1.00 | 0.64 m² |
| Tree basin | Ring | Outer 1.5 m, Inner 0.3 m | 1.00 | 6.79 m² |
Wetted area is the surface footprint that receives water during a cycle. Knowing it helps you match watering to root zones, reduce dry bands, and avoid wasting water outside planting areas. With a clear footprint, you can set sprinkler spacing, select dripline runs, and document assumptions. This calculator standardizes irrigation shapes and produces area outputs on each site.
Sprinklers are treated as a circle or a sector using arc degrees. Driplines and soaker hoses are treated as a strip using length and average wetted width. Basins or tree rings are treated as an annulus using outer and inner radii. Single emitters are treated as circular spots; an estimator provides a planning radius from flow, soil type, and duration.
Enter dimensions in meters, centimeters, millimeters, feet, or inches, then the tool converts internally. Results can be reported in square meters or square feet. The overlap factor adjusts the footprint for edge losses, overlap between heads, wind drift, or redistribution from runoff. Use below one for gaps and above one for deliberate overlap.
When total flow and runtime are provided, the calculator estimates applied volume and average depth across the wetted area. Average depth supports zone comparisons and helps check that cycle settings fit infiltration. If depth seems high, use shorter cycles with soak periods, lower flow, or wider wetting to reduce ponding. Depth is an average; distribution varies.
Measure a zone, run the calculator, then observe the wet boundary after irrigation. Adjust radius, width, or basin dimensions until results match what you see. Keep the same unit choices and overlap logic across zones for consistency. Export CSV for audits and PDF for records. Recheck after nozzle changes, tuning, or schedule updates.
It represents the ground surface that receives water during an irrigation cycle. It helps compare watering patterns across sprinklers, driplines, emitters, and basins, and supports better spacing, scheduling, and record keeping.
Start with 1.00. Use 0.85–0.95 if edges miss coverage or wind reduces reach. Use 1.05–1.20 if heads intentionally overlap, or runoff redistributes water onto adjacent soil.
It is a planning estimate based on flow, runtime, and soil type. Confirm by running a normal cycle and measuring the wet boundary on site, then switch to the known radius mode for reporting.
The same volume spread over a larger area produces a smaller average depth. Enter total flow and runtime to estimate volume, then use the calculated area to approximate depth for comparisons between zones.
Measure sprinkler radius and arc, strip wetted width, or basin radii after a typical run. If you only know flow, record emitter rating and runtime, then validate the estimated footprint visually.
Use CSV to archive inputs and results for multiple zones, then filter or compare in a spreadsheet. Use PDF for site files, maintenance notes, and client handoffs that require a simple, printable summary.
