Plant Spacing & Count
Calculate how many plants fit in a garden bed at a given spacing in a square or staggered (triangular) layout, free online.
About this calculator
In a square grid each plant uses spacing² of area. A staggered (triangular) layout is denser: each plant uses 0.866 × spacing². Number of plants ≈ usable area ÷ area per plant. Leave a margin of half the spacing along the edges.
