Plant Spacing Calculator

Find how many plants fit a bed at a given spacing.

Bed length

Bed width

Plant spacing

Plants needed (plants) 40

Bed area 40

Formula: plants = area ÷ (spacing in feet)²

Step-by-step with your numbers:

1. Values used:

2. Bed length = 10

3. Bed width = 4

4. Plant spacing = 12

6. Plants needed = Bed length x Bed width = 10 x 4 = 40plants

7. Bed area = Bed length x Bed width = 10 x 4 = 40

Did we solve your problem today?

Plan a flower bed or vegetable plot: how many plants fit at your chosen spacing (square grid).

The math behind it

Each plant occupies a spacing × spacing square. Plants ≈ bed area ÷ (spacing in feet)².

10 × 4 ft bed (40 ft²), 12 in spacing → 40 ÷ 1² = 40 plants.

Square vs triangular spacing?

Triangular (offset rows) fits ~15% more plants but is harder to lay out.
