Crown moulding, also known as crown molding, is a decorative trim installed where the walls meet the ceiling. It adds a finishing touch and creates a seamless transition between the two surfaces. However, before diving into the installation process, it is crucial to accurately measure the crown moulding to achieve a professional-looking result. Fret not, as we will guide you through the entire process step by step.

1. Understanding the Different Types of Crown Moulding

Types of Crown Moulding Material

When it comes to crown moulding, there are various materials to choose from, each with its unique characteristics and charm. Common options include wood, MDF (medium-density fiberboard), polyurethane, and plaster. Consider the style you want to achieve and the durability of the material before making your selection.

Profiles and Designs

Crown moulding comes in a wide range of profiles and designs, allowing you to find the perfect fit for your home’s architectural style. From classic and traditional to modern and contemporary, there are endless options to explore. Take time to research and select a profile that complements your space and personal taste.

2. Measuring Crown Moulding: Step-by-Step Guide

Tools You’ll Need

Before measuring your crown moulding, gather the necessary tools to ensure an accurate result. You’ll need a tape measure, pencil, miter saw, coping saw, and a sturdy ladder. Once you have everything ready, follow these steps:

Step 1: Measure the Length of the Walls

The first step is to measure the length of the walls where you plan to install the crown moulding. Use a tape measure and record the dimensions. Remember to measure each wall individually, as they may vary in length.

Step 2: Determine the Moulding Drop

The next step is to determine the “drop” or the distance between the ceiling and the top edge of the moulding. This measurement will determine the angle at which you will cut the moulding. The standard drop is usually around 2-4 inches, but it can be adjusted according to your preference and ceiling height.

Step 3: Calculate the Miter and Bevel Angles

Calculating the miter and bevel angles is crucial for achieving precise cuts and seamless corners. For each wall, measure the angle between the wall and the ceiling. Use these measurements to set the appropriate miter and bevel angles on your miter saw.

3. Tips for Installing Crown Moulding

Prepping the Walls and Moulding

Before installing the crown moulding, it’s essential to prepare both the walls and the moulding for a successful installation. Remove any existing trim or baseboards and ensure that the walls are clean and smooth. Additionally, sand or prime the moulding if necessary.

Using Corner Blocks

If you’re new to crown moulding installation, using corner blocks can simplify the process and result in cleaner corners. Corner blocks are pre-made blocks that fit into the corners, eliminating the need for cutting complicated angles.

Nailing and Gluing

Secure the crown moulding to the wall using a combination of nails and adhesive. Start by nailing the moulding into place, spacing the nails evenly along the length. Then, apply a small amount of adhesive to the back of the moulding to ensure a sturdy and long-lasting bond.


Congratulations, readers! You are now equipped with the knowledge and skills to measure and install crown moulding like a pro.
