Spray Volume Per Acre Calculator
Work out the spray water volume per acre and how many tanks you need for a field.
Spray volume per acre = tank size × tanks used per acre. This is the carrier-water figure every dilution depends on; it varies with crop canopy, nozzle and walking pace, so base it on calibration, not a guess.
Always follow the product label — the label is the law. Verify doses, PHI and compatibility with the manufacturer and local regulations before spraying.
Spray operators and farmers use the free Spray Volume Per Acre Calculator for an accurate answer in seconds — no formulas to remember, works offline in the field.
About Spray Volume Per Acre Calculator
The 'spray volume per acre' (carrier water) is the figure that turns a per-acre chemical dose into a per-tank dose — get it wrong and every spray is mis-dosed. It depends on the crop canopy, nozzle and your walking pace, so it must come from calibration rather than habit. This tool derives the volume per acre from your tank size and the number of tanks calibration showed you need per acre, and totals the water and tank loads for the whole field.

Frequently asked questions
What spray volume per acre should I use?+
It depends on the crop and equipment — typically 100–200 litres per acre for field crops with a knapsack, less for herbicides, more for dense orchard canopies. Determine yours by calibration (spray a measured area) rather than guessing.
How many sprayer tanks will I need for my field?+
Tanks per acre (from calibration) × area in acres. This tool gives the total tank loads and total water so you can plan refills and how much chemical to pre-measure.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline in the field and your data never leaves the device.
