About this calculation

Results are mathematical layout estimates based on the dimensions and spacing you enter. Actual plant counts can differ because of edge margins, paths, bed shape, equipment access, skips, headlands, variety, growing method, and field conditions. Follow your seed packet, grower guide, agronomist, or local Extension recommendations for spacing and seeding decisions.
