Accurate measurements are crucial when replacing your door. This guide will walk you through the steps to measure your door correctly to ensure a perfect fit.
This process is the same for both uPVC doors and Composite doors.
Why Accurate Measurements Matter
Before we dive into the measuring process, it’s important to understand why precision is key:
- A well-fitted door prevents drafts and improves energy efficiency
- Proper measurements ensure smooth operation and security
- Accurate sizing avoids costly mistakes and unnecessary adjustments
Tools You’ll Need
Gather these tools before you start:
- Metal tape measure
- Notepad and pen
- Spirit level (optional)
- Helper (recommended)
Step-by-Step Measuring Guide
Step 1: Measure the Width
- Measure the width of the door opening at three points: top, middle, and bottom.
- Record the smallest measurement to ensure the door fits at its narrowest point.
- Measure from brick to brick (allowing 10mm allowance) or measure the frame frame edge to edge.
Step 2: Measure the Height
- Measure the height at three points: left side, centre, and right side.
- Again, note the smallest measurement.
- For full frame replacement, measure from the top of the brickwork to the threshold.
Step 3: Check for Square
- Measure diagonally from corner to corner in both directions.
- If these measurements differ significantly, your opening may not be square, which is important to note.
Step 4: Measure Frame Depth
- Measure the depth of the existing frame if you’re replacing just the door.
- This ensures your new door will fit properly within the current frame.
Step 5: Note Opening Direction
- Determine if your door opens inwards or outwards.
- Stand inside your property to check if the door opens towards you (inward) or away from you (outward).
Tips for Accurate Measurements
- Always measure twice to confirm your readings.
- Use a metal tape measure for accuracy, as fabric ones can stretch.
- When measuring, ensure the tape is straight and taut.
- Round down to the nearest millimetre, not up.
- If you’re unsure, it’s better to measure slightly larger and trim down if needed.
Common Mistakes to Avoid
- Measuring the old door instead of the frame or opening
- Forgetting to account for the threshold when measuring height
- Assuming all sides are perfectly square without checking
- Not considering the frame depth for a replacement door
When to Seek Professional Help
While measuring a UPVC door can be a DIY task, there are situations where professional assistance is advisable:
- If your door opening is significantly out of square
- When dealing with non-standard door sizes or shapes
- If you’re unsure about any part of the measuring process
- When replacing both the door and frame in older properties
