How to Calculate Tree Spacing

What is Tree Spacing?

Tree spacing calculators determine how many trees fit in a given area using a grid or triangular planting pattern. Proper spacing ensures light, water, and root space for healthy growth.

Formula

Spacing (feet) = √(Area per tree) | Typical: 15–25 ft apart for mature canopy spread | Check species maturity

Step-by-Step Guide

  1. 1Trees per row = Area width / Spacing
  2. 2Number of rows = Area length / Row spacing
  3. 3Total trees = Trees per row × Number of rows
  4. 4Triangular spacing increases density by ~15%

Worked Examples

Input
20m × 10m area, 3m spacing
Result
(20/3) × (10/3) ≈ 6 × 3 = 18 trees in a square grid
