Are you here because you’re wondering about the standard door width in Australia? You’ve found the right place, because whether you’re a homeowner planning an extension or renovation, an architect designing something new or a builder ensuring compliance with regulations, knowing all the ins and outs of the standard door size Australia wide is critical.

Is there a standard door size Australia wide?

It’s crucial knowledge for making the most informed decisions for a functional and accessible design that ensures compliance with Australian building codes and standards. From fitting key items of furniture through doorways to ensuring ease of movement for people needing special accessibility, the width of a door plays a pivotal role in the design and usability of any space.

But before we do anything else, let’s answer the question that’s probably most pressing in your mind: the standard door size Australia wide:

It’s 820mm – the standard door width all across the country for normal interior residential doors. Why 820? It’s the perfect balance between ease of access and the efficient use of space.

Beyond standard: The wider world of door widths

However, while 820mm is the ‘standard’, that doesn’t mean it’s a one-size-fits-all solution. There’s also:

Wider doors for accessibility: Public buildings and accessible homes tend to use doors ranging from 920mm to 1020mm wide. This is to accommodate wheelchairs and mobility aids.

Narrower doors for space efficiency: On the other hand, smaller widths – like 720mm, are common in space-constrained areas like wardrobes and small bathrooms

Why the variation?: Doors come in different sizes to address specific building, room and personal needs, whilst still complying with Australian standards for accessibility and safety.

Also consider:

  • Standard door width for external doors is usually wider than internal doors – more like 920mm
  • There is a specified minimum door width Australia wide, according to construction code NCC 2022. It requires a minimum clear opening of 820mm for at least one external doorway, for accessible safety.
  • Double door sizes for larger openings, like living areas or grand main entrances, means double 820mm – for a total of 1600mm
  • You can always go for a non-standard custom width for unique architectural designs or specific aesthetic choices, but be aware of the higher costs and specific design requirements
  • It’s also worth noting the standard door height, which is typically 2040mm in Australia.

Expert insights: 9 must-know tips for Australian door widths

Has that answered all your questions about standard door widths in Australia? Let’s now shift focus to some practical tips to keep in mind when thinking about door sizes for your next project:

1. Measure twice, install once

Always double-check your measurements before buying or installing doors. Consider both the width and the required swing space.

2. Consider the purpose

Choose door widths based on the room’s function. That means wider doors for living areas and accessible designs; and narrower for small rooms or wardrobes.

3. Keep regulations in mind

Always ensure compliance with the Australian building codes, for both safety, accessibility and the law.

4. Plan for future needs

Consider wider doors for homes you intend to grow old in – because you might have mobility needs tomorrow that you don’t need today.

5. Factor in furniture & appliances

Make sure door widths accommodate the movement of large furniture or appliances.

6. Seek professional advice

When in doubt, consult with an architect, builder or home renovation or extension specialist.

7. Don’t forget aesthetics

Remember, door size impacts the overall look and feel of a space, so balance functionality with design preferences.

8. Understand cost implications

Be aware that non-standard door widths can be more expensive due to custom manufacturing and installation requirements.
