Plant spacing

Lay out a rectangular planting grid.

How this works

Plants per row = floor(length ÷ plant spacing); rows = floor(width ÷ row spacing). Multiply the counts.

Example

Using the example inputs, rectangular grid capacity is 32 plants.

Bed length
8 ft
Bed width
4 ft
Plant-to-plant spacing
12 in
Row spacing
12 in
Rectangular grid capacity
32 plants

Assumes a half-spacing margin at every edge. Choose spacing from the plant’s growing guidance.

Scope and assumptions

A layout calculation, not a planting recommendation. Mature size, crop type and access paths affect practical spacing.
