Recommended Sizes by Room Type

Not sure what size sliding door suits your space? Here’s a quick guide to help you pick the best fit based on where the door will go:

Bedroom: Go for narrower sliding doors around 1500mm to 1800mm wide, paired with frosted or tinted glass for added privacy without blocking natural light.

Living Room: To open up your living space, choose larger doors between 2400mm and 4800mm wide. They bring in more daylight and make the room feel bigger and more connected to the outdoors.

Dining Room / Kitchen: Opt for mid-sized doors around 2100mm to 3600mm wide to maintain easy flow to a patio, deck, or garden—perfect for entertaining or casual dining outdoors.

Office / Studio: For internal areas, compact sliding doors between 620mm and 920mm wide work well. They’re ideal for saving space while still creating a flexible, modern layout.

Custom Aluminium Sliding Door Sizes

Custom aluminium sliding doors are ideal for non-standard openings, tall ceilings, or when you want a clean, seamless design.

You can tailor the height, width, panel count, glass type (like Low-E, frosted, or double-glazed), frame finish, and hardware to suit your space and style.

Thanks to its strength and lightweight nature, aluminium is perfect for supporting large custom panels without compromising ease of use or durability.

How to Measure for a Sliding Door

Getting your measurements right is key to a smooth installation and long-term door performance.

Follow these five simple steps to make sure your aluminium sliding door fits perfectly.

1. Measure the Door Width

Measure the width at the top, middle, and bottom of the opening using a reliable tape measure. Use the smallest measurement to avoid gaps or fitting issues.

2. Measure the Height

Take three height measurements—left side, center, and right side of the opening. Again, use the smallest value to ensure the door fits evenly, especially on uneven floors.

3. Measure the Frame Depth

Measure the full depth of the wall or jamb where the frame will be installed. This tells you how thick your door system can be to fit snugly.

4. Check for a Square Opening

Measure diagonally from top-left to bottom-right, then from top-right to bottom-left. If both measurements match, your frame is square—if not, be prepared for adjustments during installation.

5. Account for Track or Rail Space

Check the top and bottom areas where the sliding track will go and measure their available clearance. This ensures there’s enough room for smooth, unobstructed sliding.

Does Door Size Affect Cost?

Yes, larger aluminium sliding doors generally cost more due to the extra glass, reinforced tracks, and structural support they require.

Prices also vary based on material, glass type, and hardware, so it’s smart to balance your budget with the door’s function and design appeal.
