Ridge Height Calculator

Formula

The formula to calculate the Ridge Height is:

\[ RH = H + \left( \frac{W}{2} \right) \times \tan(A) \]

Where:

\(RH\) is the ridge height (meters)
\(H\) is the height of the wall (meters)
\(W\) is the width of the building (meters)
\(A\) is the pitch angle of the roof (degrees)

What is Ridge Height?

Ridge height refers to the measurement from the base of a building to the highest point of its roof, typically the peak of the roof’s ridge. This measurement is often used in building regulations to ensure structures do not exceed a certain height, and it can also impact aspects like wind resistance and drainage.

Example Calculation 1

Let's assume the following values:

Height of the Wall (H) = 3 meters
Width of the Building (W) = 10 meters
Pitch Angle of the Roof (A) = 30 degrees

Using the formula:

\[ RH = 3 + \left( \frac{10}{2} \right) \times \tan(30^\circ) = 5.89 \text{ meters} \]

The Ridge Height is 5.89 meters.

Example Calculation 2

Let's assume the following values:

Height of the Wall (H) = 4 meters
Width of the Building (W) = 12 meters
Pitch Angle of the Roof (A) = 45 degrees

Using the formula:

\[ RH = 4 + \left( \frac{12}{2} \right) \times \tan(45^\circ) = 10.00 \text{ meters} \]

The Ridge Height is 10.00 meters.
