Plant Spacing Calculator
Find how many plants fit in a bed or field at a chosen spacing.
About the Plant Spacing Calculator
Enter the bed's length and width, the spacing between plants and a square or triangular pattern. The calculator gives the number of plants, rows and plants per square metre.
In a square grid each plant occupies spacing² of ground; offsetting alternate rows (triangular or equilateral spacing) packs plants about 15% more densely while keeping the same distance between neighbours. Counts include plants on both edges.
The formula
Square: plants ≈ (L ÷ s + 1) × (W ÷ s + 1); triangular row gap = s × √3 ÷ 2
Worked example
A 10 × 1.2 ft bed at 0.3 ft (about 3½ in) spacing, square grid
- Along: 10 ÷ 0.3 + 1 = 34 plants
- Across: 1.2 ÷ 0.3 + 1 = 5 rows
- 170 plants; triangular spacing fits about 15% more
Questions people ask
Where do I find spacing?
On the seed packet or a growing guide for the variety.
Closer spacing for more yield?
Up to a point; crowding increases disease and lowers fruit size.
