Plant count depends on where the centres fit after margins are left around the bed.

Enter centre spacing and edge clearance, then compare the two rectangular orientations.

## Why use this tool

The layout basis helps you mark real plant positions instead of dividing area by an unexplained density.


## Before relying on the result

Rectangular rows only. Spacing is centre to centre; the diagram caps its displayed plants without changing totals.


## Tool limitations

Rectangular rows only. Spacing is centre to centre; the diagram caps its displayed plants without changing totals.

## Questions

### Does the diagram always show every plant?

Large layouts may cap the displayed points. The reported count still follows the entered dimensions.

### What should I check before using Plant Spacing Calculator?

Check Inside length, Inside width, Spacing along a row and Spacing between rows. Use the exact units shown beside the controls and replace any example values with your own inputs.
