What Size Gaps Should I Use for my Aluminium Slat Fence in Perth?

Aluminium slat fences are one of the most versatile and stylish fencing options for Perth homes. One of the most common questions we get is about gap sizes between the slats. The space you choose affects privacy, airflow, light, and the overall look of your fence.

The gap between aluminium slats isn’t just a design detail, it influences your fence in several ways. Narrow gaps provide maximum privacy, making them ideal for street-facing fences or areas where you want to block views. Wider gaps allow airflow and light, which is useful in gardens or backyard areas. Gap size also affects security, helping keep kids or pets safe, and contributes to the overall style of your property.

Why Slat Gap Size Matters

Common Gap Sizes in Aluminium Slat Fences

Choosing the right gap depends on your location, privacy requirements, and the style you want. For example, side gates and backyard fences often benefit from narrower gaps, while front fences can be slightly wider for a welcoming feel.

Our most common gap sizes are:

5mm Gaps: Very high privacy while still allowing a touch of light. Popular for side gates or backyard fences where privacy is important.

10mm Gaps: Balances privacy with light and visibility. Commonly used for front fences, letting light in and maintaining some street view while still looking secure.

How to Choose the Best Gap Size

When deciding what size gap you want in between your aluminium slats, consider the following:

Privacy Needs: For homes on busy streets, smaller gaps are usually best.

Pets and Kids: Narrow gaps prevent small pets or children from climbing the fence.

Location of the Fence: Front fences often need more privacy, while backyard fences can be slightly more open.

Style Preferences: Sometimes it simply comes down to what look you prefer.
