Planting Density
Convert bed spacing into density per square foot and meter.
About Planting Density
Density divides a square foot of bed by the area each plant occupies, then scales it to metric. Density figures translate between systems and let growers compare bite-sized beds with field-scale plantings.
Formula
Planting Density
Density = 12 x 12 / (row x plant spacing); per m2 = per sq ft x 10.764
- 10.764
- Square feet in one square meter
Worked example
With the default values below, Planting Density returns Density of 0.67. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Planting Density calculated?

Why does Planting Density matter?
Density figures translate between systems and let growers compare bite-sized beds with field-scale plantings.
What values do I need to enter?
This calculator takes 4 inputs: Bed width, Bed length, Row spacing, Plant spacing. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
