#### Tip

Carpet, flooring and molding are all sold in linear feet.

#### Warning

Be careful not to mix measurements when adding your recorded sums. For example, if one area measures 11 inches and another measures 2 feet, make sure to convert the feet to inches before adding the two.

Every angle of a wall must be measured to find its total space in linear feet.

When installing molding, wainscoting, wallpaper or other decorative elements, it is important to know a wall's measurements in linear feet. When hanging art in galleries or displaying merchandise for sale in a retail space, it is important to know the amount of usable wall space. A linear foot is a measurement which is used to calculate the total length of a wall without concern for its height or any other factor. To calculate your total wall space in linear feet, you will require a bit of mathematical ability and some basic tools.

## Step 1

Use your tape measure to record the length of your wall in inches. Measure the full distance from one end of the wall to the other.

## Step 2

Use your tape measure to record the length of every portion of the wall's surface in inches. For example, if your wall turns a corner, has a protruding notch, or a recessed notch, each of these must be measured as well. The idea is to measure and record every inch of the wall's surface in a straight line, from one end to the other, including its bends and edges.

## Step 3

Use your calculator to add up each of the measurements obtained in steps 1 and 2. Divide the sum by 12 inches to convert it into feet. The sum will equal the total wall space in linear feet.
