Crown Molding Angle Chart
Pre-computed miter and bevel settings for common crown molding spring angles at 90° corners.
90° Corner (standard walls)
| Spring Angle | Miter | Bevel | Comp. Miter | Comp. Bevel |
|---|---|---|---|---|
| 38° 52/38 crown — most common | 38.2° | 31.6° | 51.8° | 58.4° |
| 45° 45/45 crown | 35.3° | 35.3° | 54.7° | 54.7° |
Miter = miter gauge setting. Bevel = blade tilt.
Complementary angles are for saws that read from the fence or tilt the other way.

Crown molding spring angles explained
The "spring angle" is the angle between the back of the crown molding and the wall when the crown is held in position. The two most common types:
- 52/38 crown — the back makes a 38° angle with the wall (52° with the ceiling). This is the most common residential crown molding. Sometimes labeled "38° spring" or "52/38."
- 45/45 crown — equal angles to wall and ceiling. Less common but simpler to work with.
To check your crown's spring angle: hold a piece against the wall in its installed position and measure the angle between the back and the wall with a protractor or angle finder.
How to use this chart
- Identify your crown molding's spring angle (38° or 45°).
- Find the row in the chart above.
- Set your miter saw's gauge to the Miter value.
- Tilt the blade to the Bevel value.
- If your saw reads differently, use the complementary columns.
- Always test on scrap first.
What if my walls aren't 90°?
Older homes often have corners that aren't exactly 90°. If your joints don't close tightly with the chart values, measure your actual corner angle with an angle finder and use the Compound Miter Calculator for exact settings.
