The Basal Area Calculator calculates the basal area per acre of a forest based on the Diameter at Breast Height (DBH) of trees and the Number of Trees per Acre.
Basal area is a key measure in forestry that indicates the density of a forest, providing valuable insights for forest management, biodiversity, and timber assessment.
How to use the Calculator:
- Enter the Diameter at Breast Height (DBH) in inches.
- Enter the Number of Trees per Acre.
- Click Calculate to view the Basal Area per Acre in square feet.
- To clear all inputs and start a new calculation, click Reset.

DBH |
12 in |
Trees per Acre |
100 |
Basal Area per Acre |
(to be calculated) |
Calculation |
0.005454 × 12² × 100 = 78.13 ft² |
In this example, with a DBH of 12 inches and 100 trees per acre, the basal area per acre is calculated as 78.13 square feet.
Example 2

Trees per Acre |
80 |
Basal Area per Acre |
(to be calculated) |
Calculation |
0.005454 × 15² × 80 = 98.19 ft² |
For a forest with an average DBH of 15 inches and 80 trees per acre, the basal area per acre is 98.19 square feet, reflecting the density of trees within that area.
