Miter Angle (saw setting) =
Jig Miter Angle (saw setting) = 0
Returns the saw settings to cut a miter from the wall angle. Saw setting is the miter of an angle translated to the angles of the saw. For example, an angle measures 120° half of 120 is 60 so 60° is the miter angle. However, on the saw 60° is actually 30°. Here's why: when the saw is set to 0° it actually forms a 90° angle. So now all saw angles are off by 90°.
All angles will be displayed as saw settings.
- Wall Angle: physical angle of the wall
- Miter Angle (saw setting): angle to set the miter saw.
- Jog Miter Angle: if the saw cannot create the angle desired as most saws are limited to 55-60° angles, instead use a 45° jig. Cut a piece of wood at a 45° angle and clamp it to the saw to use as an auxiliary back fence then set the saw to the 45° Jig Miter Angle.

What's the miter angle (saw setting) to cut a 140° edge?
- Wall Angle: 140°
The miter angle is 20°.
A wall angle measures 50 degrees. What is the miter angle?
- Wall Angle: 50°
The miter angle is 65°. Since 65° is beyond most saw's capacity, use the 45° jig and set the saw to 20°.
