Choosing the right size Australian flag is easier when you start with one question: where will the flag be displayed?
For indoor displays, the pole height usually decides the flag size. For outdoor flagpoles, the flag should look balanced against the pole height without placing too much strain on the fabric, stitching or hardware.
Use this guide to quickly match your Australian flag size to your indoor pole, outdoor flagpole or display location. You can shop standard sizes in our Australian Flags range, with larger custom sizes available by quote.
Choose Your Australian Flag Size in 4 Steps
Start with the display location
Is the flag going indoors, outdoors, on a wall, on a floor stand or on a permanent flagpole? This decides the size and finish more than anything else.
Match the flag to your pole height
For indoor displays, use the pole size below. For outdoor flagpoles, use the pole height table further down the guide.
1.8m indoor pole → 900 × 450 mm
2.4m indoor pole → 1800 × 900 mm
Think about wind and exposure
If the flag will be flown in an exposed, coastal or high-wind area, a slightly smaller flag can help reduce strain on the fabric, stitching and hardware.
Choose the right finish
Choose Header with Loops for outdoor flagpoles. Choose Vertical Sleeve for indoor display poles up to 28mm in diameter.
