How to Measure Inside Angles for Molding
- 1). Place the right side of a 360-degree adjustable protractor against one wall near the inside angle.
- 2). Move the left side of the 360-degree adjustable protractor until it reaches the opposite wall in the angle.
- 3). Write down the angle list on the protractor dial. This figure represents the angles you will need to cut in molding for the installation process.
- 4). Use the 360-degree adjustable protractor to measure each inside angle. Each corner may have a slight difference that will result in a different angle.
