Measure your actual corn field
Averages are a planning starting point — your field is its own size. The field mapper turns satellite imagery into exact acreage in four steps:
- Open the field mapper. Go to the Ag Drone Sprayers field mapper and search your address in Colorado or pan the satellite map to your field.
- Trace the boundary. Tap each corner of your field to drop pins; the tool closes the polygon and computes geodesic acreage.
- Read acreage and cost. See your field's exact acreage and an instant drone-spraying cost estimate for corn in Colorado.
- Request free quotes. Send your mapped field to drone operators serving Colorado to receive real, no-obligation quotes.

Corn field size in Colorado: FAQs
- How big is the average corn operation in Colorado?
- USDA's 2022 Census of Agriculture reports about 566 harvested acres of corn per operation in Colorado, averaged across 1,814 farms (1,027,578 acres total).
- Is average operation size the same as field size?
- No — and it's the most common mix-up. The 566-acre figure is the average corn acreage per farm; most farms split that across several fields, so a single field is typically smaller. For a real field boundary, trace it on satellite with the field mapper.

- Roughly $4,528–$10,188 for a single application (about $8–$18/acre, application only — product is extra). Extra passes, higher carrier volume, or restricted-use products raise it. Use the calculator above to adjust.
- How do I measure my exact corn field?
- Open the field mapper, trace your field on satellite imagery, and you'll get its exact acreage, an instant Colorado cost estimate, and free quotes from drone operators serving your area — no app to install.
