Taking accurate measurements is crucial for a successful sliding door installation
Even a few millimetres off can cause complications, lead to expensive adjustments, or negatively impact the final appearance. Follow these steps to get precise dimensions and make your installation process easier.
Tools You’ll Need to Measure a Sliding Door
To take accurate measurements, you’ll need:
- A measuring tape or laser measurer for precision
- A utility knife to remove silicone seals
- A pry bar to remove moldings without damaging the frame
Prep Work Before Measuring a Sliding Door
Step 1: Remove Silicone Seals
Use a utility knife to gently remove the silicone joints around the door. This ensures your measurements aren’t distorted by any added materials.
Step 2: Take Off the Moldings
Carefully remove moldings with a pry bar to expose the full width of the opening. Be cautious not to damage the frame in the process.
Measuring the Width of an Interior Sliding Door
How to Measure at Three Levels
Measure the opening width at the top, middle, and bottom. Record the smallest width, as it accounts for any warping or irregularities in the frame.
Measuring the Height of a Sliding Door
Three Key Height Points
Measure the height at the center and both sides. Again, use the smallest measurement to ensure a snug, functional fit.
Measuring the Depth and Other Door Dimensions
Depth should be measured inside the door jamb, excluding moldings. This is crucial when installing the sliding mechanism—especially for interior pocket doors or closet doors.
Tips to Avoid Measurement Errors
- Repeat each measurement two to three times for accuracy
- Use a laser measurer in hard-to-reach or irregular areas
- Write down and compare all dimensions before ordering your door
Why Choose Sliding Doors in Aluminum or Glass?
Modern sliding doors—often made of aluminum or glass—offer a sleek look and high durability. These materials are lightweight and ideal for tight spaces, making them a top choice for contemporary interiors.
Measuring Correctly: A Quick Summary
Choosing and installing quality sliding doors starts with accurate measurements. Whether you’re working with glass, interior sliders, or aluminum models, knowing how to get the exact dimensions is key to a perfect result.
