How the estimate works

Positions = floor(row length ÷ spacing) × rows.

Seeds = positions ÷ germination rate × extra allowance.

Worked example

Two 10-foot rows at 3-inch spacing, 80% germination, and 10% extra require 110 seeds.

Assumptions

  • One seed is counted per planned position before germination allowance.

Limitations

  • Packet counts vary by crop, variety, and supplier; this tool returns seed quantities only.
