Door and window knowledge: how to accurately measure wooden doors

The front door is the face of your home, and choosing the right wooden door is essential for both aesthetics and functionality. One of the most important steps in this process is accurately measuring the door opening. Proper measurements ensure a smooth installation and prevent costly mistakes later on.

Key Steps for Measuring Wooden Doors

1. Start by measuring the height of the door opening. Take three measurements from left to right—top, middle, and bottom—to ensure accuracy. This helps identify any unevenness in the wall or floor.

2. It’s crucial to install the door before laying the floor. If you lay the floor first, it can create challenges when installing the door and baseboards. For example, the threshold between rooms must align directly under the door, and without the door in place, it's difficult to position the flooring correctly.

Why Install the Door First?

There are several reasons why the door should be installed before the floor:

(1) The threshold between rooms needs to be placed directly under the door. If the floor is already down, it becomes hard to determine the exact position of the threshold.

(2) Once the floor is laid, the baseboards are installed. Without the door cover in place, the baseboards on either side can’t be properly fixed. This leads to extra work and delays. By installing the door first, the door cover can sit directly on the ground, allowing the floor installer to cut the necessary space under it. A gap of 2–2.5 cm is typically reserved under the door to accommodate the floor thickness.

How to Measure the Door Opening Correctly

Facade width = Door width + Door jamb width

Door width = Door panel width + Clearance + Frame thickness + Solid panel thickness + Adjustment margin

Measuring the Door Hole:

- Width: Measure horizontally across the door opening at five or more points. Use the smallest measurement (after subtracting the adjustment margin) as the final width.

- Height: Measure vertically from top to bottom. Again, take multiple measurements and use the smallest value after accounting for the adjustment margin.

Important Note: During the measurement, make sure the floor is level and account for the thickness of the flooring material. This ensures that the door fits perfectly once installed.

Preparation Before Measurement

Before taking any measurements, the ground must be leveled, and the floor thickness must be confirmed. Many new homes have uneven floors, and even small discrepancies can cause problems if not accounted for. Don’t wait until the floor is fully installed to measure—confirm the thickness early so the team knows what to expect.

In kitchens and bathrooms, where tiling is required, traditional wooden doors are often filled with foam for better stability. This means the walls need to be thick enough to support the door frame. Therefore, it’s best to measure after the tiles are laid, ensuring the wall is properly leveled and the measurements are accurate.

Essential Conditions Before Measuring:

1. Customer and construction manager must be present.
2. Hydro and wall renovation must be complete.
3. Level lines should be available. Kitchen and bathroom tiles should be laid, and the floor should be leveled. All heights and thicknesses must be determined.

Things to Watch Out For During Measurement

Before installing the door, the surveyor should check the door opening size carefully. Any inaccuracies can lead to installation issues. Here are some key considerations:

1. The door opening must be straight and vertical. The left and right walls should have the same thickness and be aligned. Otherwise, the door may not fit properly, and there could be gaps or uneven seams.

2. Surveyors will provide specific instructions based on the actual measurements. Make sure to confirm the dimensions with the manufacturer before proceeding with any modifications.

3. Different door series may have varying dimensions. Be careful when placing the door over different materials like tiles or masonry. Avoid having two different materials meet at the door’s location, which can look unprofessional.

If the wall thickness or door opening doesn't match standard sizes, the construction team may need to modify the wall before the door is installed. This could involve cutting, extending, or adjusting the opening. These steps help ensure a seamless installation and avoid future issues.
