Plant spacing calculator
How many plants fit in a garden bed at a given spacing, in square or triangular rows.
Edges and paths reduce the count slightly, so measure only the planted area.
How this calculator works
Square grid: plants = area ÷ spacing². Triangular (offset) rows fit about 15% more plants: plants = area ÷ (spacing² × 0.866).
Worked example: a 10 m² bed at 30 cm spacing holds 111 plants in a square grid, or 128 in offset rows.
