Shoe and Clothing Size Converter

The shoe and clothing size converter helps you translate sizes between different regional standards, including UK, US, EU, and Asian sizing systems. Whether you are shopping internationally or buying a gift for someone overseas, this tool removes the guesswork from finding the right fit.

How to Use the Shoe and Clothing Size Converter

1. Select the item type: shoes, tops, bottoms, or dresses.
2. Choose the sizing system you already know, such as UK, US, or EU.
3. Enter your current size.
4. Select the target sizing system you want to convert to.
5. Read your converted size in the results panel.

The Formula

Clothing and shoe sizes are not calculated using a single mathematical formula. Instead, they are based on standardised measurement tables maintained by regional standards bodies. Each country developed its own sizing conventions historically, which is why a UK size 12 dress is not the same as a US size 12.

For shoes, EU sizes are based on Paris points, where one Paris point equals two-thirds of a centimetre. A UK men's shoe size 9 corresponds to EU 43 because the foot length in centimetres maps to that Paris point value. US sizes shift by approximately 0.5 to 1 size relative to UK sizes depending on gender.

For clothing, sizes are derived from body measurements in centimetres or inches (chest, waist, hips), which are then mapped to a labelled size. A UK women's size 14 corresponds roughly to a 38-inch hip, which maps to EU 44 and US size 10.

Real-World Example

You wear a UK women's size 12 and want to order a dress from a German retailer using EU sizing.

• UK women's size 12 corresponds to a bust of approximately 36 inches (91 cm) and a hip of approximately 38 inches (96 cm).
• Using the standard UK-to-EU clothing conversion, UK 12 maps to EU 40.
• You would order an EU size 40 from the German retailer.

Always check the specific retailer's size guide, as brand-level vanity sizing can shift results by one size.

Why Sizes Vary So Much Between Regions

Sizing standards were developed independently in different countries before any international agreement existed. The UK and Australia share similar clothing size frameworks, while the US runs two sizes smaller than UK for women's clothing. EU sizes are derived from body measurements in centimetres, making them more consistent in theory but still subject to brand variation. Asian sizing (Japanese and Korean in particular) tends to run smaller than Western standards across both clothing and footwear.

The ISO (International Organization for Standardization) has published technical specifications for clothing size designations, including ISO 3635 for size designation of clothes and ISO 4415 for footwear, but these are reference documents rather than binding standards. Most retailers still apply national tables or their own in-house grading. This is why the same waist measurement in inches can land you in a UK 32, a US 32, an EU 46, or a Japanese 79 depending on the label.

How to Measure Yourself Accurately

best results when using a size converter, take your own measurements before consulting any chart:

• Chest / bust: measure around the fullest part, keeping the tape level under the arms and across the shoulder blades. Do not puff out the chest.
• Waist: measure at the natural waistline, which is the narrowest part of the torso, usually just above the navel.
• Hips: measure around the fullest part of the hips, typically 18 to 20 cm below the waistline.
• Inside leg: measure from the crotch seam to the bottom of the ankle, on a pair of trousers that fit well.
• Foot length: stand on a piece of paper with the heel against a wall, mark the tip of the longest toe, and measure the distance.

For shoes, measure both feet at the end of the day when the feet are slightly swollen; most people have one foot slightly larger than the other, and you should fit to the larger foot.

Common Mistakes When Converting Sizes

1. Ignoring gender-specific offsets: a men's US 9 is not the same shoe as a women's US 9, even though the number matches. The women's last is typically built on a different last shape and is approximately 1.5 sizes larger in absolute foot length terms.
2. Mixing systems across categories: children's sizes use different conversions than adult sizes. A children's US 4 is not the same as an adult US 4 shoe.
3. Trusting the label alone: two pairs of trousers both labelled "size 32" can have a 4 cm difference in actual waist circumference between brands.
4. Skipping brand-specific charts: convert your measurements to the brand's base chart before ordering online, especially from international retailers.
5. Assuming consistency within a brand: even within a single retailer, a "size 12 dress" and a "size 12 jumper" can refer to different body measurements because dresses are graded on bust and hip while knitwear is graded on chest alone.

Frequently Asked Questions

Are EU shoe sizes the same for men and women? Yes, EU shoe sizes use a single unisex scale based on foot length. The difference lies in the UK/US conversion, where men's and women's sizes differ by approximately 1.5 sizes from the same EU number.

Why does my size vary between different clothing brands? Brands apply their own grading and may use different base measurements. This is sometimes called vanity sizing, where brands label garments larger than the actual body measurement to make customers feel they wear a smaller size. Always measure yourself and compare against the specific brand's size chart.

What is the best way to find my EU shoe size? Measure the length of your foot in centimetres while standing. Multiply by 1.5 and add 2 to get an approximate EU size. For example, a 26 cm foot gives EU 41. A size converter table will give a more precise result.

Do children's clothing sizes work the same way? Children's sizes are generally based on age or height rather than body measurements, so a size 4 typically fits a child aged around 4 years or of a certain height. Conversion between UK, EU, and US children's sizes follows similar but separate tables to adult sizing.

How accurate is the conversion for jeans? Jeans sizing is particularly inconsistent across brands because denim is often sized in inches (waist × inseam) in the US, in arbitrary numbers (28, 30, 32…) in the UK, and in centimetres in EU markets. A "size 30" jean can have a measured waist anywhere from 30 to 32 inches depending on the brand. The converter gives a starting point, but always check the brand's specific measurement chart before ordering.

Should I size up or down if I am between sizes? Generally size up rather than down, garments can be altered by a tailor, but a too-small item cannot be made larger. For shoes, an insole can take up a small amount of extra room, but a shoe that pinches cannot be fixed.

What does the Mondopoint system measure? Mondopoint is the ISO standard for shoe sizing, expressed directly in millimetres of foot length. It is used in some military and orthopaedic contexts but is not common in consumer retail. If you see a Mondopoint size, it is essentially the same as a centimetre measurement of your foot.

Inputs and Their Effects

Each field on the Shoe and Clothing Size Converter form plays a distinct part in the calculation.

• the item type: shoes, tops, bottoms, or dresses - this value feeds the Shoe and Clothing Size Converter directly and shows up in the result.
• the sizing system you already know, such as UK, US, or EU - this value feeds the Shoe and Clothing Size Converter directly and shows up in the result.
• your current size - this value feeds the Shoe and Clothing Size Converter directly and shows up in the result. Editing one field of the Shoe and Clothing Size Converter changes the output in line with the formula, so a misplaced value is visible in the answer.

Common Mistakes to Avoid
