A cathedral ceiling is a sloped ceiling with equal rise on all sides, often ending in a peak in the center of the room. These types of ceilings give an open feel to a floor plan and can make rooms look larger and feel more spacious. If you want to paint your cathedral ceiling, you'll need a measurement of surface area to determine how much paint you'll need for the entire ceiling.
Instructions
1. Divide the ceiling into individual triangles at the corner or each wall. Draw a picture of the ceiling and divide it into triangles that way if you need the visual aid.
2. Measure the base and height of each triangle in the cathedral ceiling. Write down that measurement.
3. Multiply each triangle's base by each height. Divide that number by two. For example, if the base is 12 and the height is 10, the equation will look like this: 12 x 10 = 120, 120 / 2 = 60. The final number is the area of each triangle.
4. Add all the areas to get the surface area of the cathedral ceiling.
