Tree Leaves Calculator

Roughly estimate the number of leaves on a tree.

Calculated Output

Estimated leaves 197,920.34

Canopy area 706.86

Formula: leaves ≈ canopy area × leaves per ft²

Step-by-Step Breakdown

1. Values used:

2. Canopy diameter = 30

3. Leaves per ft² of canopy = 280

5. Estimated leaves = 197,920.34

6. Canopy area = 706.86

Did this calculator solve your problem today?

The math behind it

canopy area = π × (diameter/2)²; leaves ≈ area × leaves per ft². A mature tree has on the order of 200,000 leaves.

30 ft canopy → ~198,000 leaves.

Accurate?

No — it's an order-of-magnitude estimate; leaf density varies enormously by species.
