Plant Spacing and Plant Count Calculator (Garden Beds)

How to use the Plant Spacing and Plant Count Calculator (Garden Beds)

1. Choose metric or imperial units.
2. Enter the length and width of the bed, and the spacing from the seed packet or plant label.
3. Choose a square grid or a staggered layout.
4. Read how many plants fit and the planting density.

Example

Worked example (bed 3 m × 1.2 m, 30 cm spacing)

• Square grid: 10 × 4 = 40 plants
• Area: 3.60 m², 11.1 plants per m²
• Staggered: 4 rows (10, 9, 10 and 9 plants), which gives 38, so no gain in a narrow bed
• Bed 3 m × 3 m: 100 in a square grid, 105 staggered (11 rows)

Limitations

• The bed is treated as a rectangle with plants half a spacing in from the edge. Some crops tolerate planting right to the edge.
• The right spacing depends on the variety and growing method, so follow the seed packet.
• The staggered figure is an idealised count.

About this tool

The Plant Spacing and Plant Count Calculator tells you how many plants fit in a garden bed. Enter the bed’s length and width and the spacing between plants, and choose a square grid or a staggered layout, which can fit more plants in a wide bed. It assumes plants sit half a spacing in from the bed’s edges. Use the spacing printed on the seed packet or plant label.
