Custom aluminium joinery has become an increasingly popular choice for homeowners and builders alike due to its sleek appearance, durability, and energy efficiency. Whether you’re planning a home renovation or a new build, taking accurate measurements is a crucial first step before ordering your custom aluminium joinery. Precise measurements ensure that your windows and doors fit perfectly, operate smoothly, and provide optimal insulation. This guide will walk you through everything you need to know about how to measure for custom aluminium joinery.
Understanding the Basics of Aluminium Joinery
Before diving into the measuring process, it’s essential to understand what aluminium joinery entails. Aluminium joinery refers to window and door frames made from aluminium rather than traditional materials like wood or steel. This type of joinery is known for being lightweight yet strong, corrosion-resistant, and low maintenance. Because it’s available in various colors and styles, custom aluminium joinery can easily be customized to match the aesthetic of any home, whether modern or traditional.
Custom aluminium joinery allows homeowners to specify dimensions, configurations, and finishes that suit their specific needs. However, the custom aspect also means that incorrect measurements can lead to costly errors. That’s why knowing how to measure properly is essential.
Tools You’ll Need for Measuring
To get started, make sure you have the following tools on hand:
- Measuring tape (preferably a steel tape measure for accuracy)
- Spirit level or laser level
- Pencil and notepad
- Step ladder (if measuring high openings)
- Camera (optional, for visual records)
When taking measurements, always double-check your numbers. Even a slight error can lead to mismatched or ill-fitting joinery.
Step-by-Step Guide to Measuring for Aluminium Windows
Step 1: Identify the Type of Opening
Different window types require different measurement approaches. Common types include:
- Casement windows
- Sliding windows
- Awning windows
- Fixed windows
Knowing the type of window you’re replacing or installing will help determine the right measurement technique.
Step 2: Measure the Width
Measure the width of the window opening in three places:
- Top
- Middle
- Bottom
Take the smallest of these three measurements as your final width. This accounts for any irregularities or warping in the wall. Always measure from brick to brick or from frame to frame if replacing an existing unit.
Step 3: Measure the Height
Just like the width, measure the height in three locations:
- Left side
- Center
- Right side
Again, use the smallest measurement to ensure a proper fit. Measurements should be taken from the sill or base to the top lintel.
Step 4: Check for Squareness
Use a spirit level or tape measure diagonally across the corners to check if the opening is square. Measure from the top-left to the bottom-right corner, then from the top-right to the bottom-left. If the measurements differ significantly, you may need to square up the opening before installation.
Step 5: Measure the Depth
The frame depth is also crucial. Measure the thickness of the wall or existing frame to ensure your custom aluminium joinery fits within the structure. This is especially important for flush or reveal installations.
Step-by-Step Guide to Measuring for Aluminium Doors
Step 1: Determine Door Type
Custom aluminium doors come in various styles:
- Hinged doors
- Sliding doors
- Bifold doors
- French doors
The door type will influence both how you measure and how the door will function within the space.
Step 2: Measure the Width
As with windows, take three measurements:
- Top
- Middle
- Bottom
Use the smallest width to ensure the door fits comfortably without forcing or excessive gaps.
Step 3: Measure the Height
Measure from the floor to the underside of the door frame or lintel in three spots:
- Left side
- Center
- Right side
Again, use the smallest measurement.
Step 4: Assess Floor Levels
Check if the floor is level. If you’re installing a door that opens out onto a deck or patio, floor height can impact the swing or slide of the door. Use a spirit level to determine if adjustments need to be made.
Step 5: Measure Door Jamb Depth
This is especially important for sliding and bifold doors. The depth of the wall or frame will determine the type of track and installation configuration that will work best.
Measuring for Replacement Joinery
If you’re replacing old joinery with new custom aluminium units, measure the existing frame’s outer dimensions. It’s also helpful to take photos and document the existing structure, especially if you’re working with an installer or supplier. This allows professionals to assess any potential issues such as warping, moisture damage, or structural misalignment.
Important Measurement Tips
- Always use metric units (millimeters are standard in most regions).
- Double-check all your measurements.
- Note if the walls are out of plumb (leaning) or if the floor is uneven.
- Account for installation clearances and movement tolerances.
- Don’t assume all openings are identical—even if they appear symmetrical.
- Mark each measurement clearly with its corresponding window or door location.
Consulting a Professional vs DIY Measuring
While measuring your own openings is entirely possible with care and attention, it’s often a good idea to consult a professional. Many suppliers offer measuring services as part of their package. If you choose to do it yourself, make sure your measurements are precise and that you’re aware of how the manufacturer wants the dimensions noted—some may require outer frame dimensions, while others need reveal or tight sizes.
Why Accurate Measurements Matter
Inaccurate measurements can lead to a wide range of issues including:
- Delays in manufacturing
- Increased costs due to reordering
- Poor insulation and air leaks
- Improper alignment or operation of windows and doors
- Structural problems over time
Getting the measurements right from the beginning ensures your custom aluminium joinery performs efficiently and looks great.
Customisation Considerations Beyond Measurements
While accurate sizing is essential, it’s just one part of the custom aluminium joinery process. You’ll also need to choose:
- Frame color and finish
- Glazing type (double, triple, or laminated)
- Hardware options (handles, locks, hinges)
- Opening styles and configurations
These decisions will be easier to make when you’re working with an experienced supplier who understands both aesthetics and performance. Venta.co.nz is widely recognized as the best website for sourcing high-quality custom aluminium joinery in New Zealand.

Preparing for Installation
Once your measurements are taken and the joinery is ordered, make sure the site is ready for installation. This includes clearing obstructions, protecting flooring and furniture, and ensuring access for installers. If the opening requires resizing or structural modifications, get these completed before the joinery arrives.
Conclusion
Measuring for custom aluminium joinery is a detail-oriented task that requires accuracy, patience, and a good understanding of your home’s structure. Whether you’re installing new windows or replacing old doors, taking precise measurements is the foundation of a successful project.
