Plant Spacing Calculator

Estimate how many plants fit in a rectangular bed. Compare a regular grid with staggered triangular rows using the spacing you choose.

Geometry estimate only. Uses a rectangular bed and half-spacing edge margins; real plants may need different spacing, paths and growth room. Follow the guidance for your variety and check the layout before planting.

How do I calculate plant spacing and population?

Enter the bed dimensions and center-to-center spacing within and between rows. This calculator places the first and last centers half a spacing from each edge, then counts the layout. A staggered pattern offsets alternate rows by half the in-row spacing.

Frequently asked questions

How do I calculate plant spacing and population?

Enter the bed dimensions and center-to-center spacing within and between rows. This calculator places the first and last centers half a spacing from each edge, then counts the layout. A staggered pattern offsets alternate rows by half the in-row spacing.

Are my garden dimensions uploaded?

No. The estimate runs locally in your browser; dimensions are not sent to a server or saved by this tool.

What is triangular plant spacing?

Alternate rows are shifted by half the in-row spacing. This creates a staggered pattern; the number of plants can differ from a regular grid.

Does this choose the right spacing for my plant?

No. It only counts a layout from the dimensions you enter. Use seed-packet, nursery or local extension guidance to choose spacing for the variety and growing conditions.
