Frequently Asked Questions
What is the spring angle on crown moulding and why does it matter?
The spring angle is the angle at which crown moulding sits against the wall and ceiling, typically 38 or 45 degrees. This angle determines how crown sits in your compound mitre saw for cutting corners. Knowing the spring angle before cutting is essential; using the wrong angle setting produces joints that will not close.
How do I calculate the right crown moulding size for my room?
As a general rule, ceiling height in inches divided by 12 gives you an approximate crown width in inches. A room with 9-foot ceilings suits approximately 4.5-inch crown. Smaller rooms with lower ceilings look best with narrower, simpler profiles. Larger, more formal rooms support wider crown with greater projection.
What is the difference between wood and MDF crown moulding?
Wood crown accepts stain and can match existing wood millwork in colour and grain. MDF crown is smoother and more consistent for painted applications and is less expensive. Wood is also slightly more forgiving of minor fitting issues since it holds paint better after touch-up. Use MDF only in dry interior conditions.
Can I install crown moulding without a compound mitre saw?
It is possible using a standard mitre saw by positioning the crown moulding upside down against the fence at its spring angle, but this is awkward and requires practice. A compound mitre saw allows the moulding to lie flat and the blade to cut the compound angle in one pass, making cuts significantly easier and more consistent.
What is the best way to handle crown moulding in rooms that are not perfectly square?
Test each corner with an angle finder before cutting. Corners in older homes rarely land on a perfect 90 degrees. Adjust your mitre angles accordingly. Many installers split the difference across both pieces when a corner is slightly off. Caulking and filling before painting hides minor gaps in out-of-square corners.
