Calculate seed spacing, in-row plant spacing, seed drop, row spacing, seeds per acre, and total field seed needs. Use this seed spacing calculator for corn, soybeans, cotton, vegetables, and other row crops.
Seed spacing from population:
Enter target population and row spacing to calculate the needed in-row seed spacing.
Population from spacing:
Enter row spacing and seed spacing to estimate seeds or plants per acre.
Seed drop per foot:
The calculator converts seed spacing into seeds planted per foot of row.
Total seed needed:
Use field acres, target population, emergence rate, and seeds per bag to estimate total seed and bags needed.
A seed spacing calculator helps estimate how far apart seeds should be placed in each row to reach a target population.
It can help with planter setup, seeding rate planning, stand estimates, seed bag estimates, and field planting cost estimates.
Your result shows estimated seed spacing, population per acre, seed drop per foot, row feet per acre, total seed needed, seed bags needed, and estimated seed cost. These are estimates based on the values you enter.
Multiply 43,560 square feet per acre by 144 square inches, then divide by row spacing in inches and target population per acre.
Divide 12 by seed spacing in inches. For example, 6-inch spacing equals 2 seeds per foot of row.
Narrower rows allow more row length per acre, so seed spacing in the row can usually be wider while keeping the same population.
Yes. Enter field acres and seeds per bag to estimate total seed needed and the number of seed bags required.
