How To Convert High Heel Heights from Inches to Millimetres

Understanding the height of your high heels is crucial, especially when you're navigating through international shoe sizes. The process of converting high heel heights from inches to millimeters may seem daunting at first, but it's actually a straightforward mathematical exercise.

The key formulas for conversion are simple:

10mm equals 1 cm, and 2.54cm equals 1 inch.

In reverse, 1mm equals 0.039 of an inch.

For instance, if you have a heel height of 3.5 inches and you want to convert it to millimeters, you would multiply 3.5 by 25.4 (the number of millimeters in an inch), resulting in a heel height of 89mm.

When measuring the height of your heels, start from just above the heel cap up to the center of the heel, where it meets the sole. Place the shoe on a flat surface and use a tape measure for accuracy. Shoe manufacturers typically do not include the heel cap in their measurements.

It's important to note that the height of most high heels increases as the size of the shoe gets larger. This maintains the proportions of the shoe. For example, a 100mm (3.9 inch) heel is more manageable than a 120mm (4.7 inch) heel, which can be notoriously difficult to wear and walk in.

Converting between international high heel sizes doesn't have to be a painful process. With a reliable shoe size conversion chart, you can easily swap between USA shoe sizes and European, Australian, and British sizes. Remember, US and Australian sizes for high heels are exactly the same, so no conversion is needed between these two.

However, there is no absolute international standard for shoe size conversion, and even leading manufacturers may differ slightly in their calculations. If a brand publishes its own shoe size conversion chart, it's advisable to follow that if it differs from the general chart.
