Start from the population you want and get the spacing to plant at. Each plant needs area ÷ population, laid out in rows, squares or triangles.

Also called: Planting distance calculator.

## Inputs
- Target population (default 60000)
- Population is per (options: Hectare, Acre, Square metre; default ha)
- Layout (options: Rows, Square, Triangular; default rows)
- Row spacing (default 75)
- Spacing in (options: cm, inches; default cm)

## Results
- Spacing between plants
- Distance between rows
- Area per plant
- Plants per hectare
- Plants per acre

## Formula

```
Area per plant A = Area unit ÷ Population;  Rows: spacing = A ÷ Row spacing;  Square: s = √A;  Triangular: s = √(2A ÷ √3), rows s × √3 ÷ 2 apart
```

Where:
- A: area each plant occupies
- s: distance between neighbouring plants

## Worked example
1. Area per plant = 10,000 m² ÷ 60,000 = 0.1667 m².
2. In-row spacing = 0.1667 ÷ 0.75 m = 0.2222 m = 22.22 cm.

**Result:** For 60,000 plants per hectare in 75 cm rows, space plants 22.2 cm apart in the row.

## What the result means

Spacing and output units follow the unit you choose (cm or inches). Triangular planting fits about 15% more plants than square planting at the same plant-to-plant distance.

## Assumptions and limits
- Plants are evenly spaced; one plant per station.
- Planters and seed plates set spacing in steps, so round to the nearest setting your equipment offers.

## Questions

### What is triangular (hexagonal) spacing?

Each plant sits at the corner of equilateral triangles, so every neighbour is the same distance away. Rows are offset and set √3/2 (0.866) of the plant spacing apart.

### How do I get spacing for a seed drill?

Use the Rows layout with your drill’s row width and divide the result by your establishment rate if you want seed spacing rather than plant spacing.
