Shoe Size Conversion NZ

Quick answer Enter a size in any system and this converts across NZ/AU, US, UK and EU scales for men, women and kids. The scales are offset from each other, and half-size rounding differs by brand, so treat the converted size as the starting point for a fit check.

This calculator converts a shoe size between the UK/NZ, US and European systems and the equivalent foot length in centimetres, which is useful because New Zealand uses UK sizing while many online stores, especially in the United States or Europe, list sizes on their own local scale. You start by choosing men's or women's sizing, since the two use different scales, then select your UK/NZ size from the dropdown. The calculator instantly returns your matching US size, EU size, and the foot length in centimetres, alongside your original UK/NZ size for reference. Below the result sits a full conversion chart covering every UK/NZ size from smallest to largest, with the US, EU and centimetre equivalents shown side by side, so you can check a range of sizes at once or work out where you sit between two sizes. Because every shoe brand cuts its patterns, or lasts, slightly differently, no conversion chart can guarantee a perfect fit, so treat the numbers here as a reliable starting point rather than the final word. The most dependable figure when shopping online is the centimetre foot length. Measure your foot as described below and match it against the brand's own size guide wherever one is provided, particularly if you are between sizes or ordering from an overseas retailer, and remember this is a guide only, not a guarantee of fit.

Measuring your feet

Stand on a sheet of paper with your heel to a wall, mark your longest toe, and measure the distance in centimetres. Measure both feet late in the day and use the larger one. Matching the centimetre length to the chart is more reliable than guessing between brands.

Frequently asked questions

What shoe size system does New Zealand use?

New Zealand uses UK shoe sizing, the same as the United Kingdom and Australia. So if you know your NZ size, it is your UK size. This tool converts that to US and European sizes and to the foot length in centimetres.

How do I measure my foot length?

Stand on a piece of paper with your heel against a wall and mark the tip of your longest toe. Measure from the wall to the mark in centimetres, and measure both feet in the afternoon when they are largest. Use the larger foot and match the centimetre length in the chart.

Why do sizes differ between brands?

Conversion charts are a guide, but the fit varies by brand and style because each maker uses its own lasts. If you are between sizes or buying online, the centimetre length is the most reliable measure to compare against a brand's own size guide.
