Enter the gable width (ft) and the gable height (ft) into the Gable Roof Area Calculator. The calculator will evaluate the Gable Roof Area.

## Gable Roof Area Formula

The following two example problems outline the steps and information needed to calculate the Gable Roof Area.

GRA = GW * GH/2
• Where GRA is the Gable Roof Area (ft^2)
• GW is the gable width (ft)
• GH is the gable height (ft)

To calculate the gable roof area, multiply the gable width by the gable height, then divide by 2.

## How to Calculate Gable Roof Area?

The following example problems outline how to calculate Gable Roof Area.

Example Problem #1:

1. First, determine the gable width (ft).
• The gable width (ft) is given as: 30.
2. Next, determine the gable height (ft).
• The gable height (ft) is provided as: 5.
3. Finally, calculate the Gable Roof Area using the equation above:

GRA = GW * GH/2

The values provided above are inserted into the equation below and computed.

GRA = 30 * 5/2 = 75.00 (ft^2)

Example Problem #2:

For this problem, the variables required are provided below:

gable width (ft) = 60

gable height (ft) = 10
