Plant spacing calculator

Measure the usable growing area, leaving paths out. Use the spacing on your seed packet or in advice suited to your variety and growing conditions. Choose metric or US customary units, and keep all inputs in the selected system.

Method and limitations

Plant count = floor(area × unit factor ÷ (plant spacing × row spacing)): the factor is 10,000 for m² and cm, or 144 for ft² and inches. This is a rectangular area estimate, not a bed layout: narrow beds, edges and access paths can reduce the number that fits.
