Description
For positive spacing, return spacing × sqrt(3)/2 between triangular rows and density 2/(sqrt(3) × spacing²).
Spacing calculations place ideal points or modules within a stated geometric extent. End margins, row patterns, and partial border positions affect the count.
For positive spacing, return spacing × sqrt(3)/2 between triangular rows and density 2/(sqrt(3) × spacing²).
When to use this tool
Use Planting Triangle Row Density Factor when you need an explicit planting or paving layout-count term.
How to use the tool and how it works
- Enter spacing, area. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read rowSpacing, density, approximatePlants. Use the output convention below.
For positive spacing, return spacing × sqrt(3)/2 between triangular rows and density 2/(sqrt(3) × spacing²). Multiply density by area for approximatePlants.1

| area | Area | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| rowSpacing | Row Spacing | Required. Finite number. |
| density | Density | Required. Finite number. |
| approximatePlants | Approximate Plants | Required. Finite number. |

}Limitations and assumptions
- The estimate is fractional and ignores boundary losses, obstacles, growth, and species requirements.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use a complete site layout that includes boundaries, obstacles, growth, joints, and installation allowances.
