Whether you’re a forester, arborist, woodworker, or environmental scientist, accurately estimating the weight of a tree is vital for many applications—from logging and transport planning to ecological studies and carbon offset calculations. That’s where our Tree Weight Calculator comes in—an intuitive and precise tool that lets you calculate tree mass and volume within seconds.
Tree Weight Calculator
What Is the Tree Weight Calculator?
The Tree Weight Calculator is a web-based tool designed to calculate the approximate weight (in kilograms) and volume (in cubic meters) of a tree based on:
- Tree Height (m)
- Trunk Diameter (cm)
- Wood Density (kg/m³)
The formula assumes the trunk is approximately cylindrical, providing a scientifically reasonable estimate for most tree species and use cases.
Why Use a Tree Weight Calculator?
Here are some scenarios where this tool is extremely useful:
- Forestry operations: Estimate how much wood can be harvested.
- Transport planning: Avoid overload penalties by estimating log weight.
- Carbon offset projects: Measure biomass for sustainability assessments.
- Construction or woodworking: Calculate the yield of raw wood.
- Ecological research: Estimate biomass for habitat or ecosystem modeling.
How the Tree Weight Calculator Works
The calculator uses the following core formulas:
- Volume of the tree trunk (as a cylinder): Volume=π×r2×h\text{Volume} = \pi \times r^2 \times hVolume=π×r2×h Where:
- rrr is the radius in meters (trunk diameter ÷ 2 ÷ 100)
- hhh is the height in meters
- Weight is calculated using: Weight=Volume×Wood Density\text{Weight} = \text{Volume} \times \text{Wood Density}Weight=Volume×Wood Density
This simple yet powerful logic ensures high precision for general-purpose use.
How to Use the Tree Weight Calculator
Follow these easy steps:
- Enter Tree Height (in meters):
Example:10 - Enter Trunk Diameter (in centimeters):
Example:30 - Enter Wood Density (in kg/m³):
Example:600
(Common densities: Oak ≈ 700, Pine ≈ 500, Teak ≈ 650) - Click “Calculate”:
Instantly see the estimated tree volume and weight. - To clear inputs, click Reset.
Example Calculation
Let’s say you’re calculating for a medium-sized oak tree:
- Height: 12 meters
- Trunk Diameter: 35 cm
- Wood Density: 700 kg/m³
Step-by-step:
- Radius = 35 cm ÷ 100 ÷ 2 = 0.175 m
- Volume = π × (0.175)² × 12 ≈ 1.154 m³
- Weight = 1.154 × 700 = 807.8 kg
Results:
- Tree Volume: 1.15 m³
- Tree Weight: 807.8 kg

20 Frequently Asked Questions (FAQs)
1. How accurate is the Tree Weight Calculator?
The tool provides scientifically accurate estimates based on cylindrical trunk approximation and input values.
2. What if I don’t know the wood density?
You can Google the typical density of your tree species or use an average value (e.g., 600 kg/m³ for mixed hardwoods).
3. Can I use feet or inches instead of meters and centimeters?
Currently, the tool uses metric units. Use a converter before inputting values.
4. Does this calculator work for all types of trees?
Yes, as long as you provide the correct inputs. Accuracy improves with precise density values.
5. What if the tree has an irregular shape?
The calculator assumes a cylindrical trunk. It may not account for flares or multiple stems.
6. Is the calculated weight the fresh or dry weight?
It gives approximate green (fresh) weight unless you input the dry wood density.
7. Can this tool be used for carbon sequestration estimates?
Yes, with volume and density, you can further calculate carbon storage.
8. How is the tree volume calculated?
Using the formula: π × radius² × height.
9. Does this work for standing trees only?
Yes, it's designed for estimating standing tree weight.
10. Can I embed this calculator on my own site?
No, but you can link to the tool hosted on your domain.
11. How is the trunk diameter measured?
Measure at chest height (typically 1.3 meters above ground), also known as DBH.
12. Is this calculator mobile-friendly?
Yes, it's responsive and works well on all devices.
13. What’s the typical density of common woods?
- Pine: 500 kg/m³
- Oak: 700 kg/m³
- Teak: 650 kg/m³
- Birch: 670 kg/m³
14. How do I get exact height and diameter?
Use a measuring tape for diameter and a clinometer or laser for height.
15. Can I calculate the weight of multiple trees?
Yes, just repeat the calculation with new inputs.
16. Is the tree weight inclusive of branches?
No, it primarily estimates trunk weight.
17. What units are used for weight and volume?
Weight is in kilograms (kg) and volume is in cubic meters (m³).
18. Does this calculator account for tapering?
No, it uses a cylindrical approximation, which is suitable for most mature trees.
19. Is this tool free to use?
Absolutely, it's a free utility on your website.
20. Can I print or save the results?
Yes, you can copy or take a screenshot of the results for your records.
