## Tree Height CalculatorViewpoint Level with Base of Tree

H = h + D * tan(Theta)
 h Distance From Ground to Intercept of Horizontal Line (feet) D Distance from Tree to Viewpoint theta Angle from Viewpoint to Top H Height of Tree(feet) =

## Tree Height CalculatorViewpoint above Base of Tree

H = D * (tan u + tan d)
 D Horizontal Distance from Viewpoint to Tree (feet) u Angle from Viewpoint to Top of Tree d Angle from Viewpoint to Bottom of Tree H Height of Tree(feet) =

## Tree Height CalculatorViewpoint Below Base of Tree

H = D * (tan u - tan d)
 D Horizontal Distance from Viewpoint to Tree (feet) u Angle from Viewpoint to Top of Tree d Angle from Viewpoint to Base of Tree H Height of Tree(feet) =

## Leaning Tree Height CalculatorViewpoint Above Base of Tree

H = D x (tan(u) + tan(d))
The next two calculators give the height of the tree above the ground, not the length of the tree.
 D Distance from Tree to Viewpoint u Angle from Viewpoint to Top of Tree d Angle from Viewpoint to Base of Tree H Height of Tree(feet) =

## Leaning Tree Height CalculatorViewpoint Below Base of Tree

H = D x (tan(u) - tan(d))
 D Distance from Tree to Viewpoint u Angle from Viewpoint to Top of Tree d Angle from Viewpoint to Base of Tree H Height of Tree(feet) =
