## Wound Surface Area Formula

The following two example problems outline the steps and information needed to calculate the Wound Surface Area.

WSA = GL * GW

- Where WSA is the Wound Surface Area
- GL is the greatest length
- GW is the perpendicular greatest width

To calculate the wound surface area, multiply the greatest length by the perpendicular greatest width.

## How to Calculate Wound Surface Area?

The following example problems outline how to calculate Wound Surface Area.

Example Problem #1:

- First, determine the greatest length.
- The greatest length is given as: 3.

- Next, determine the perpendicular greatest width.
- The perpendicular greatest width is provided as: 5.

- Finally, calculate the Wound Surface Area using the equation above:

WSA = GL * GW

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

WSA = 3 * 5 = 15.00

Example Problem #2:** **

For this problem, the variables required are provided below:

greatest length = 4

perpendicular greatest width = 2
