US Men's to EU Converter

To convert US Men's to EU, add 33 to the US Men's size: EU = US Men + 33. For example, US Men's 9 → EU 42.

The US Men's (US M) is the US Men's shoe sizing scale, running approximately 33 sizes below the EU equivalent (e.g., EU 42 = US Men's 9).

The EU (EU) is the European shoe sizing standard, a numeric scale where adults typically range from EU 36 to EU 47, derived from the Paris point system.

For men: add 33 to the US size (US 10 ≈ EU 43). For women: add 31 to the US size (US 8 ≈ EU 39). These are approximations — sizing varies by brand. When buying shoes online, always check the brand's specific size chart and consider measuring your foot length in cm for the most accurate fit.

Men's UK sizes are 1 size smaller than US (US 10 = UK 9). Women's UK sizes are 2 sizes smaller than US (US 8 = UK 6). Both US and UK sizes use the same scale but start at different points. EU sizes are the same for men and women, making them easier to use internationally.

Stand on a piece of paper, trace around your foot, then measure the longest distance from heel to toe in centimeters. EU size ≈ foot length in cm × 1.5 + 2, or look up a size chart. Feet are often slightly different sizes — always fit to the larger foot. Feet also tend to swell during the day, so measure in the afternoon.

US children's size 3 corresponds to approximately EU 35. Children's sizing varies more by age and brand than adult sizing. For growing children, a thumb's width (about 1 cm) of space at the toe is recommended to allow for growth without the shoe being so large it causes tripping.

Not always. Running shoes are often recommended in a half-size to full size larger than casual shoes because feet swell during exercise and you need toe clearance when running downhill. Boots may require a half size up if worn with thick socks. Always try on athletic footwear with the socks you intend to wear during activity.
