What Size Australian Flag Should I Buy?
Choosing the right size Australian flag is about more than just looks. The flag needs to suit your flagpole height, the building or space it’s in front of, and how far away people will be when they see it. Get the proportions right and your flag will look proud, balanced and professional — whether it’s flying outside a home, a school or a council building.
At Evan Evans, we manufacture premium Australian National Flags in a full range of sizes and finishes. This guide explains the real-world sizes we produce, how to match them to your flagpole, and which options work best for homes, schools, councils and corporate sites.

Short Answer
For most Australian flagpoles, the best all-round choice is our 1800 × 900 mm Australian flag on a 6 metre pole. It’s the standard size we keep in stock at Evan Evans and suits schools, community facilities and many homes.
Smaller poles (3–4 m) pair well with 900 × 450 or 1370 × 685 mm flags, while councils and large sites often choose 2300 × 1150 mm or larger.

How to Match Flag Size to Flagpole Height
As a general guideline, the length of your flag should be roughly one quarter to one third of the pole height. This gives a visually balanced result while keeping the flag manageable in Australian wind conditions.
- 3–4 m poles: 900 × 450 mm or 1370 × 685 mm
- 4–5 m poles: 1370 × 685 mm for everyday use
- 6 m poles (most common school pole): 1800 × 900 mm (Evan Evans standard size)
- 7–8 m poles: 2300 × 1150 mm
- 8–9 m poles: 2750 × 1380 mm
- 9–10 m poles: 3200 × 1600 mm
- 10–12 m+ poles: 3600 × 1800 mm
If your site is particularly exposed or coastal, it can be wise to choose the smaller of the two suitable sizes to reduce load on the pole and extend the life of your flag.
Flag Size Recommendations by Site Type
Homes & Residential Properties
- Typical pole: 3–5 m aluminium or fibreglass.
- Recommended sizes: 900 × 450 mm or 1370 × 685 mm for smaller poles; 1800 × 900 mm for taller 6 m installations.
- Best for: Daily flying, national days, sporting events and family celebrations.
For homes set back from the road or situated on acreage, stepping up to 1800 × 900 mm helps your flag remain visible from a greater distance.
Schools & Education Campuses
- Typical pole: 6 m, often grouped in sets of three.
- Recommended size: 1800 × 900 mm Australian National Flag, matched with Aboriginal and Torres Strait Islander flags in the same size.
- Why: Provides strong visibility across playgrounds, car parks and ovals, and photographs well for assemblies and ceremonies.
Many schools complement their flags with open day or event signage such as media walls, fabric banners and wayfinding signs to guide families on campus.
Councils & Government Buildings
- Typical pole: 7–9 m, frequently in banks of three or more.
- Recommended sizes: 2300 × 1150 mm on 7–8 m poles; 2750 × 1380 mm on 8–9 m poles.
- Usage: Australian National Flag plus Aboriginal, Torres Strait Islander and other official flags.
These larger sizes ensure flags remain legible from surrounding streets and plazas and reflect the formality of civic buildings. For major national days, councils often integrate flags with street banner flags and event signage.
Corporate, Stadium & Landmark Sites
- Typical pole: 9–12 m or taller.
- Recommended sizes: 3200 × 1600 mm or 3600 × 1800 mm.
- Best for: Stadium precincts, waterfront promenades, major entries and tourism sites where high impact is essential.
At this scale, it’s critical that poles, footings and fixings are designed for the additional wind load. Our team can coordinate flag specifications with your engineers to ensure a durable and compliant solution.
Vertical Flags & Custom Flag Sizes
Not every project calls for a traditional horizontal flag. Many councils, venues and businesses now use vertical hoist flags or architectural banner-style flags on tall poles.
- We apply the same width-to-height ratio rules used for horizontal flags so vertical flags remain properly proportioned.
- Custom heights can be matched to your pole and wind environment.
- Vertical flags can be produced in Australian National, Aboriginal, Torres Strait Islander or fully custom designs.
Because Evan Evans manufactures in-house, we can tailor custom flag sizes to suit heritage buildings, architect-designed poles or special event requirements while still aligning with Australian flag protocol.
Materials & Finishes: Size Isn’t the Only Decision
Once you know your flag size, the next decision is material. For Australian conditions, we typically recommend:
- Printed trilobal polyester: A slightly lustrous, durable fabric ideal for everyday outdoor use and event display.
- Woven polyester: Strong, workhorse fabric for high-wind or coastal sites where longevity is critical.
- Fully sewn flags: Premium, traditional construction suited to government, memorial and heritage locations.
Our Australian flag product page lets you choose size, material and finishing, including rope and toggle or sister clips for easy installation.
Flag Care: Helping Any Size Flag Last Longer
Larger flags experience more movement and wind load, so care makes a big difference to lifespan:
- Lower flags in extreme wind or storms where safe to do so.
- Inspect stitching and attachment points regularly and change out the flag before heavy fraying occurs.
- Rotate between two flags so each one has rest periods.
- Clean and store flags properly when not in use.

Do I Need Council Approval for My Flagpole?
Flag size and flagpole approval are related but separate issues. Many standard-height residential flagpoles are treated as minor structures, but there are important exceptions for taller poles, heritage precincts and strata properties.
If you’re planning a new installation, we recommend reading our guide: Do You Need Permission to Install a Flagpole at Home in Australia?

For a typical 3–5 m home flagpole, we usually recommend 900 × 450 mm or 1370 × 685 mm. If your pole is 6 m or your house is set back from the street, you may prefer 1800 × 900 mm for extra impact.
