How to Measure for an Accurate Australian to US Size Conversion
The surest way to find your correct size is to measure your foot. This simple process eliminates guesswork and helps you find the perfect fit, especially when buying online from the US.
Measurement Steps:
- Gather Supplies: Find a hard floor, a wall, a piece of paper larger than your foot, a pen or pencil, and a ruler or tape measure (with CM & IN).
- Position Foot: Place the paper on the floor against the wall. Stand on the paper with your heel firmly against the wall. Wear the type of socks you'd normally wear with the shoes. Ensure your weight is evenly distributed.
- Trace Outline: Have someone else trace the outline of your foot, keeping the pen held vertically (at a 90° angle) to the paper. If alone, trace carefully, ensuring the pen stays snug against your foot.
- Measure Length: Remove your foot. Draw a straight line from the back of the heel mark to the tip of the mark for your longest toe. Measure this line using your ruler in both **Centimeters (CM)** and **Inches (IN)**.
- Repeat for Other Foot: Feet are often slightly different sizes. Repeat steps 2-4 for your other foot.
- Use the Longer Measurement: Always use the measurement from your *longer* foot for conversion. Enter this CM or MM (CM * 10) value into the converter tool above for the most reliable result.

Sizing for Australian Brands like Blundstone & R.M. Williams
Iconic Aussie brands often use AU/UK sizing, but they can have unique fits. Always consult their official size charts before buying.
-
Blundstone Sizing: This famous bootmaker uses AU/UK sizing for all its boots. A key detail: their half sizes add extra width, not length. So, an AU 8.5 is wider than an AU 8, but not longer.
-
R.M. Williams Sizing: A heritage brand known for its leather boots, R.M. Williams also uses AU/UK sizing. They offer multiple width fittings (e.g., G for regular, H for wide), so checking their detailed fit guide is essential.
