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.

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.
- 3–4 m poles: 900 × 450 mm or 1370 × 685 mm
- 6 m poles: 1800 × 900 mm (most common)
