Standard Door Sizes in Australia: The 2026 Overview
When planning a renovation or new build, knowing the standard door size australia guidelines is essential. In the Australian context, a “standard door size” refers to the most commonly manufactured and readily available dimensions for both internal and external doors. These standards ensure that doors fit seamlessly into typical wall frames, allowing for easy replacement, cost-effective installation, and broad design flexibility.
Australia’s most prevalent internal door size is 820mm wide by 2040mm high, with a thickness of 35mm. This dimension strikes the right balance between accessibility, privacy, and space efficiency in most homes. However, the standard door size australia range is broad, accommodating various room functions and architectural needs. Internal doors typically range in width from 420mm for compact spaces up to 920mm for wider access points. Heights are most commonly 2040mm, but 2340mm high doors are increasingly popular in modern designs.
| Door Type | Common Width (mm) | Common Height (mm) | Typical Thickness (mm) |
|---|---|---|---|
| Internal | 420, 520, 620, 720, 770, 820, 870, 920 | 2040, 2340 | 35 |
| External | 820, 870, 920, 1020 | 2040, 2340 | 40 |
| Garage/Specialty | 2100+ | 2400+ | Varies |
For external doors, the standard door size australia measurements differ to accommodate security and insulation needs. Most front and back entry doors are 820mm or 920mm wide, with 2040mm or 2340mm heights and a thicker 40mm profile for added durability. Wider doors, such as 1020mm, are often used for statement entryways or to improve accessibility.
Door sizes have evolved alongside Australian housing trends. In older homes, such as a typical 1970s brick residence, internal doors are usually 2040mm high and may be narrower, especially in laundries or bathrooms. In contrast, a 2026 new build often features taller 2340mm internal doors, reflecting higher ceilings and open-plan living preferences. This shift not only enhances natural light flow but also creates a sense of spaciousness.
Ceiling height and architectural style strongly influence the standard door size australia options selected. Homes with 2.7m or higher ceilings now commonly use 2340mm doors to maintain visual proportion. Meanwhile, minimalist and contemporary designs favour wider and taller door profiles for a modern, airy feel.
Recent data shows the 820mm x 2040mm internal door remains dominant, but demand for the 2340mm height is growing rapidly in new developments. Many homeowners and builders are drawn to the flexibility and aesthetic value offered by larger door panels. For a detailed breakdown of these dimensions and their applications, see the Standard door sizes in Australia resource.
Consider a practical example. A 1970s brick home might have 720mm-wide internal doors and a 2040mm-tall entry, which can limit design choices during renovation. By contrast, a 2026 open-plan home will likely feature 2340mm-tall, 820mm- or 920mm-wide doors throughout, supporting accessibility and a contemporary look. Understanding the standard door size australia guidelines helps you select doors that fit, look great, and meet compliance requirements for your project.
Types of Doors and Their Standard Sizes
Choosing the right door style is more than a design decision. It is essential for compliance, function, and ease of installation. Understanding the standard door size australia options for each door type helps you plan effectively, control costs, and ensure your project runs smoothly in 2026.

| PA (Personal Access) | 600, 720, 820, 920 | 2040, 2340 | 40-45 | Garages, sheds, side access |
This table captures the most common standard door size australia dimensions for each major door type. Internal doors are often 820 mm wide and 2040 mm high, while external doors tend to be thicker and sometimes wider, especially for main entry points.
Hinged, Sliding, and Folding Doors: Sizing Differences
The way a door operates impacts its sizing. Hinged doors, including flush and panel styles, are most often found in standard widths like 820 mm. Sliding doors, whether single or double, need wider openings. For example, a standard sliding door may be 1200 mm or more to allow for smooth access and light.
Folding doors, such as bi-folds, are measured by the number of panels and their combined width. A two-panel bi-fold door can be as narrow as 900 mm, while a seven-panel version can span over 6000 mm, making it perfect for connecting living spaces to outdoor areas. The standard door size australia for folding and sliding models varies more widely because of these functional needs.
Why Not All Styles Are Available in Every Size
Not every door style is available in every standard door size australia. Structural requirements, weight limitations, and design intent restrict some options. For instance, oversized glass doors need thicker frames for stability, and double doors require wider wall spaces. French doors are usually custom paired, so their width per leaf is less than a full single door.
Manufacturers offer the most popular sizes to streamline production and reduce costs. Choosing a non-standard size usually means custom work, which can extend lead times and increase your budget.
Door Thickness: What Varies by Type
Door thickness is another important factor in the standard door size australia equation. Most internal doors are 35 mm thick, balancing weight and durability for daily use. For external doors, 40 mm is common, providing extra strength, insulation, and security.
Panel doors, especially those used as entry doors, may be even thicker for added impact resistance. Specialty doors like PA doors for garages or sheds can reach 45 mm or more, accommodating hardware and weatherproofing.
Market Share of Each Door Type in Australian Homes
Recent industry data shows flush and panel doors dominate the standard door size australia market, making up about 60% of all internal doors. Sliding and bi-fold doors are gaining ground, particularly in open-plan homes where wider access is valued. French and glass doors account for around 15%, often selected for their style and ability to maximise light.
Specialty doors, including pocket and PA doors, are seeing increased demand as homeowners seek flexible solutions for compact spaces and multi-use areas.
Specialty Focus: Personal Access (PA) Doors
PA doors are designed for convenient entry to garages, sheds, and side yards. Their standard door size australia options typically include widths of 820 mm and heights of 2040 mm or 2340 mm, but can vary to suit commercial or high-security requirements.
For a detailed breakdown of sizes and installation tips, see the Personal access doors sizing guide. This resource helps you choose the right PA door for your project, whether it is a new build or a retrofit.
Summary: Matching Door Type and Size to Your Needs
Selecting the right standard door size australia is about more than picking a look. It involves understanding the functional differences between door types, their available sizes, and how these fit your space and requirements.
Flush, panel, and glass doors suit most internal applications, while sliding, bi-fold, and double doors are ideal for open-plan areas or where space is at a premium. Specialty doors, such as PA and pocket types, provide solutions for unique access points and compact layouts.
With the right knowledge, you can confidently choose the best door style and size for any Australian home or project.
Australian Standards & Building Compliance for Doors
Navigating the world of standard door size australia means more than just picking dimensions off a chart. Every installation must comply with strict Australian Standards and the Building Code of Australia to ensure safety, accessibility, and long-term value. This compliance is not just a formality; it is essential for both legal and practical reasons.
Relevant Australian Standards for Doors
Australian regulations set out clear requirements for standard door size australia. The most important standards are:
- AS 1428.1: Accessibility requirements, including minimum clear opening widths and door handle heights.
- AS 2047: Standards for windows and external doors, covering weatherproofing and structural performance.
- Building Code of Australia (BCA): Enforces minimum and maximum door sizes, fire safety, and egress rules.
For example, AS 1428.1 specifies that accessible doors must have a minimum clear opening of 850mm when open. Door handles must be installed between 900mm and 1100mm above the finished floor. You can review specific Building Code of Australia compliance requirements for further detail.
Compliance in Practice: Minimums, Maximums, and Accessibility
Most residential internal doors in Australia are 820mm wide and 2040mm high, but compliance means ensuring these meet the minimums set for your project type. For commercial or accessible spaces, the standard door size australia may need to be wider—often 920mm or more.
Fire safety rules require that exit doors open outward and provide clear, unobstructed egress. For multi-unit dwellings, external doors must comply with both AS 2047 and local fire regulations. Handle heights, clearances, and even door swing directions are all dictated by these standards.
Recent Updates and Regional Differences
Australian Standards are regularly updated, so it is crucial to check for changes before ordering or installing. For 2026, updates to AS 1428.1 have clarified requirements for automated and smart doors, ensuring new technologies still meet accessibility rules.
While the standard door size australia remains consistent nationwide, minor variations exist between states and territories, especially regarding fire and cyclone safety in coastal regions. Builders should always consult local codes in addition to national standards.
Why Compliance Matters for Homeowners and Builders
Meeting the standard door size australia does more than tick a regulatory box. Proper compliance:
- Ensures doors are safe and accessible for everyone
- Simplifies future renovations or replacements
- Boosts the resale value of your property
- Is often required for insurance approval
For example, a new home built with compliant door sizes will easily pass inspection and appeal to a wider range of buyers, including those needing accessible features. Non-compliance can lead to costly rectifications or insurance issues down the track.
Factors Influencing Door Size Selection in 2026
Selecting the right standard door size australia is a critical decision for any renovation or new build. Several factors will shape your choice, from available space and compliance to design preferences and budget. Understanding these influences ensures your project achieves both style and function.
Renovation vs. New Build
When tackling a renovation, homeowners often need to match the existing standard door size australia to avoid costly custom orders. New builds, on the other hand, offer greater flexibility. Builders can choose larger or taller doors to suit modern designs and open-plan layouts. In both cases, sticking to standard sizes is generally more affordable and ensures easier access to replacement parts.
Space Constraints and Room Function
Limited space is a common challenge, especially in older homes or compact modern apartments. For small bathrooms, laundries, and pantries, using a narrower standard door size australia, such as 720mm wide, maximises functionality without compromising access. Bedrooms and living areas typically use 820mm doors, balancing privacy and ease of use.
- Use 720mm for tight spaces
- 820mm suits most bedrooms
- 920mm for accessibility or statement entryways
Ceiling Height and Architectural Style
The height of your ceilings and your home’s architectural style play a major role in door selection. Modern builds with higher ceilings often feature 2340mm tall doors, creating a sense of space and luxury. Classic homes may retain 2040mm doors for authenticity. Choosing the right height ensures visual harmony and compliance with architectural trends.

Accessibility and Energy Efficiency
Accessibility requirements are increasingly important in 2026. Wider doors, such as 870mm or 920mm, make homes more inclusive for wheelchair users and meet compliance standards. Energy efficiency is also a consideration, as the correct standard door size australia helps maintain insulation and reduce energy costs. Selecting insulated doors and tight-fitting frames further enhances performance.
Security and Budget Considerations
Security is a top priority for entry doors. Heavier, wider doors offer improved protection and presence. Budget also influences choice. Standard door size australia options are usually more cost-effective than custom builds, with broader availability and faster installation. Custom doors may suit unique architectural needs but often come at a higher price.
Practical Example: Modern Open-Plan Home
A builder working on a contemporary open-plan home chooses 2340mm tall doors throughout. This standard door size australia enhances natural light, creates a seamless flow, and aligns with 2026 design trends, all while keeping costs manageable by avoiding custom orders.
