Patio Fall Ratio Calculator

Formula

The formula to calculate the Patio Fall Ratio (PATR) is:

\[ PATR = \frac{D}{W} \]

Where:

\(PATR\) is the Patio Fall Ratio
\(D\) is the patio vertical drop
\(W\) is the patio width

Patio Fall Ratio Definition

The Patio Fall Ratio (PATR) is a measure used in landscaping and construction to determine the slope or gradient of a patio. It is calculated by dividing the vertical drop of the patio by its width. This ratio is important for ensuring proper drainage and preventing water accumulation on the patio surface.

Example Calculation

Let's assume the following values:

Patio Vertical Drop (D) = 0.5 meters
Patio Width (W) = 5 meters

Using the formula to calculate the Patio Fall Ratio (PATR):

\[ PATR = \frac{0.5}{5} = 0.1 \]

The Patio Fall Ratio (PATR) is 0.1.
