Tree Weight Calculator – Accurate Tree Mass Estimation

How the Calculator Works

Calculate approximate tree mass using diameter at breast height (DBH), total height, form factor and wood density. The calculator estimates volume and multiplies by density to return weight in kilograms (kg).

Tree Weight Formula

Volume = π × (Diameter/2)² × Height × Form Factor
Weight = Volume × Wood Density

Diameter (m) — DBH

Height (m)

Form Factor (0.4–0.7)

Wood Density (kg/m³)

Example Calculation

For Diameter 0.5 m, Height 10 m, Form Factor 0.5, Density 600 kg/m³ — Volume ≈ 0.98 m³, Weight ≈ 588 kg. This is an estimate for planning and safety.

Important Notes

Tree weight varies with moisture, species, and trunk form. Freshly cut timber typically weighs more due to higher water content. Use this calculator as a reliable estimate for transport, removal, and timber valuation.

How the Tree Weight Calculator Works

A Tree Weight Calculator determines the approximate mass of a tree by using its diameter, height, and wood density. These measurements together help estimate the tree’s volume, which is then multiplied by the density of the wood species. This method is widely trusted in forestry, timber harvesting, landscaping, and environmental studies because it provides a close and practical estimate without needing heavy equipment.

The calculator is designed to be user-friendly. You simply enter the diameter at breast height (DBH), total height of the tree, and select the wood type. The calculator then uses industry-standard formulas to provide a weight estimate. This helps users make better decisions related to transport planning, cutting strategies, load management, and timber valuation.

Tree Weight Calculation Formula

The standard formula used in most forestry tools includes two stages:

1. Volume = π × (Diameter/2)² × Height × Form Factor
2. Weight = Volume × Wood Density

• Diameter (D): Measured at 1.3m (DBH)
• Height (H): Total tree height
• Form Factor: Usually between 0.4 and 0.7
• Wood Density: Varies by species such as oak, pine, maple, or teak

This formula gives a close estimate of tree weight in kilograms or pounds.

Example Calculation

For a tree with:

• Diameter: 0.5 m
• Height: 10 m
• Form Factor: 0.5
• Wood Density: 600 kg/m³

The calculation becomes:

• Volume ≈ 0.98 m³
• Weight ≈ 588 kg

Although this value is approximate, it provides a dependable baseline for planning and safety considerations.

Benefits of Using a Tree Weight Calculator

• Helps determine load capacity for transportation or lifting equipment
• Provides fast estimates for forestry and academic projects
• Useful for timber buyers evaluating market value
• Assists in planning safe tree removal operations
• Saves time by offering quick results with minimal measurements

Important Notes

Tree weight can vary based on moisture content, tree species, canopy structure, and trunk shape. Freshly cut trees often weigh more due to higher water content. Despite these variations, the calculator offers a reliable estimate that works well for most practical applications.
