Understanding UK and European (EU/China) Footwear Sizing

In China, the widely used shoe sizing standard is the European sizing (EUR/EU). For example, women typically wear sizes between EUR 35–39, and men wear between EUR 39–45.

However, almost all footwear sold in the United Kingdom uses its own standard, known as UK Sizing (UK).

UK Shoe Sizes Explained

UK shoe sizes are generally represented by numbers ranging from approximately 2 to 13. Because the UK sizing system is often unfamiliar to international buyers, it’s common to be unsure about the equivalent Chinese or European size.

Below, we share the essential method for converting between UK and Chinese/EU sizing to help you confidently select the correct UK size.

The UK Shoe Size Conversion Formula: EU/China vs. UK

Although the UK and Chinese/EU size numbers look very different, you can easily calculate your ideal UK size using a simple conversion formula.

A crucial first step is accurately knowing your foot length in centimetres (cm).

How to Measure Your Foot Length Accurately

Most UK shoe brands provide their own detailed Size Guides. Because sizing can vary slightly between brands (e.g., a Nike UK 7 might fit differently from a Dr Martens UK 7), knowing your foot length in centimetres is the most reliable way to find your size on any international size chart.

Here is the simple method for measuring your foot length:

1. Place your foot flat on a sheet of white paper, with your heel firmly against a wall.
2. Use a ruler or pen to mark the distance from your longest toe to your heel. This distance is your foot length in cm.
3. Measure your other foot, as they may differ slightly. Record the longest measurement for comparison with any shoe brand's Size Chart.

Essential Shoe Size Conversion Formulas

Once you have your foot length in centimetres, you can use these formulas for basic conversions (Note: these are approximations and should always be checked against a brand's specific chart):

• UK Shoe Size Formula: Foot Length (cm) - 18 =UK Shoe Size
• European (EU/China) Shoe Size Formula: Foot Length (cm) \times 2 - 10 = EU Shoe Size
• US Shoe Size Formula (Approximate): Foot Length (cm) - 18 + 0.5 =US Shoe Size

You can also utilise various online international shoe size calculators for a quick, precise conversion.

Common UK to China/EU Size Conversions

Here are the most common UK shoe sizes and their Chinese/EU equivalents, on average:

UK Size	Equivalent China/EU Size
UK 4	EU/CN 37
UK 5	EU/CN 38
UK 6	EU/CN 39
UK 7	EU/CN 41
UK 8	EU/CN 42.5
UK 9	EU/CN 44
UK 10	EU/CN 45

Important Note: UK sizing includes half sizes (e.g., UK 7.5), and the conversion is not always a perfect whole number. Furthermore, men's and women's sizing can differ. For instance, a UK 7 is generally EU 41 for women but closer to EU 40 for men. For the most accurate fit, refer to the detailed tables below.
