Tree Spacing Calculator
Tree Spacing Calculator
Enter your planting area dimensions in feet or meters, including length and width in tree spacing calculator. Select your preferred planting pattern (square, rectangular, or triangular). Input recommended spacing distance between trees.
The calculator provides the total number of trees needed and visualizes the optimal planting layout.
- Row Spacing = 10 feet
- Tree Spacing = 10 feet
Trees per Acre = 43,560 / (10 × 10) = 435.6
Result: You can plant approximately 436 trees per acre.

How to Calculate How Many Trees Per Acre
Measure your planting area dimensions in feet. Choose your planting pattern (square, rectangular, or triangular). Identify recommended spacing between trees and between rows for your tree species.
For square patterns, divide 43,560 (square feet per acre) by the product of row spacing and tree spacing. For triangular patterns, multiply the result by 1.15 to account for increased density. Multiply your per-acre result by your total acreage for the final tree count.
- Row Spacing = 12 feet
- Tree Spacing = 8 feet
Trees per Acre = 43,560 / (12 × 8) = 453.125
Result: You can plant approximately 453 trees per acre.
- Row Spacing = 20 feet
- Tree Spacing = 15 feet
Trees per Acre = 43,560 / (20 × 15) = 145.2
Result: You can plant approximately 145 trees per acre.
Tree Spacing Formula
Square/Rectangular Pattern:
Trees Per Acre = 43,560 ÷ (Row Spacing × Tree Spacing)
Triangular Pattern:
Trees Per Acre = (43,560 ÷ (Row Spacing × Tree Spacing)) × 1.15
Total Trees = Trees Per Acre × Total Acre
The formula requires:
- Plot Dimensions: Length and width in feet
- Row Spacing: Distance between rows
- Tree Spacing: Distance between trees
- Pattern Type: Square, rectangular, or triangular
Square Pattern Example
- Area: 1 acre
- Row Spacing: 10 feet
- Tree Spacing: 10 feet
- Calculation: 43,560 ÷ (10 × 10) = 436 trees
Rectangular Pattern Example
- Area: 2 acres
- Row Spacing: 15 feet
- Tree Spacing: 10 feet
- Calculation: (43,560 ÷ (15 × 10)) × 2 = 581 trees
Triangular Pattern Example
- Area: 0.5 acres
- Row Spacing: 12 feet
- Tree Spacing: 12 feet
- Calculation: (43,560 ÷ (12 × 12)) × 1.15 × 0.5 = 139 trees
Orchard Example
- Area: 5 acres
- Row Spacing: 20 feet
- Tree Spacing: 15 feet
- Calculation: (43,560 ÷ (20 × 15)) × 5 = 726 trees
Small Plot Example
- Area: 0.25 acres
- Row Spacing: 8 feet
- Tree Spacing: 8 feet
- Calculation: (43,560 ÷ (8 × 8)) × 0.25 = 170 trees
What is Tree Spacing?
Tree Spacing refers to the planned distance between trees in a planting layout, crucial for optimal growth and management. Proper spacing ensures each tree has adequate room for root development, crown spread, and access to sunlight and nutrients. The spacing depends on tree species, soil conditions, climate, and intended use (timber, orchard, landscaping). Square patterns provide uniform spacing, rectangular patterns allow for equipment access, and triangular patterns maximize density.
