Page guide

Estimate seed count, mass and packets from your planting target, germination and establishment assumptions.

How to use Seed quantity calculator
  1. Enter your measured quantities, units and assumptions.
  2. Review the calculated result and the stated limits.
  3. Download the report or plan for your project.

Useful next steps

Describe the target stand

Enter planting stations and the desired established seedlings per station. Germination and later establishment are separate percentages, so the calculator accounts for both.

Convert the sowing quantity

Add an optional allowance, then enter measured thousand-seed weight and seeds per packet. The report shows seeds to sow, estimated mass, packets and spare purchased seeds.

Save the measurements and assumptions

Download CSV and a text or JSON report. The calculation runs on your device. Changing a unit keeps the number you entered, so check both before using the result.
