How to Measure Your Shoe Size at Home?

Our shoe calculator performs measurements according to ISO Specifications. Moreover, you can follow the guide below to estimate your shoe size at home:

• Make sure you have paper larger than your foot, a measuring tape, and a pencil
• Now keep the pencil perpendicular to the paper and place your foot on the paper
• Label your foot properly
• Step up your foot, take the paper in your hand, and flip it
• Again label your foot from the back side of it
• Now, take the measuring tape and measure the length and width of the feet at points where you get the maximum value
• Subtract 0.25mm or 0.5cm from the answer to account for the pencil marks
• Compare your result with the shoe measurement chart to know your size.

What is My Shoe Size?

Suppose your foot measurement is about 8.7 in (or 22 cm), then your shoe size is calculated as follows:

EU Shoe Size:

\[ \text{EU Shoe Size} = \frac{\text{Foot length in cm} + 2 \times 0.667}{0.667} \]

Step-by-step:

1. \(EU = \frac{22 + 2 \times 0.667}{0.667}\)
2. \(EU = \frac{22 + 1.334}{0.667}\)
3. \(EU = \frac{23.334}{0.667}\)
4. \(EU \approx 35\)

UK Shoe Size:

Formula:

\[ \text{UK Shoe Size} = (3 \times \text{Inches}) - 23 \]

1. \(UK = (3 \times 8.7) - 23\)
2. \(UK = 26.1 - 23\)
3. \(UK \approx 3\)

US Shoe Size:

Formula:

\[ \text{US Shoe Size} = (3 \times \text{Inches}) - 22 \]

1. \(US = (3 \times 8.7) - 22\)
2. \(US = 26.1 - 22\)
3. \(US \approx 4\)

You can also use a dress size calculator to see which dress size will best fit your body and match your shoes.

Common Formulas for Finding the Right Shoe Size

• US Shoe Size

US Male = \( (3 \times \text{Inches}) - 22 \)
US Female = \( (3 \times \text{Inches}) - 21 \)
US Child = \( (3 \times \text{Inches}) - 9.67 \)

• UK Shoe Size

UK Adults = \( (3 \times \text{Inches}) - 23 \)
UK Kids = \( (3 \times \text{Inches}) - 10 \)

• EU Shoe Size

EU Size = \( 1.27 \times (\text{UK Size} + 23) + 2 \)
