What is a Size 42 in Shoes?

A size 42 in shoes is a European (EU) sizing measurement. It generally converts to a US men’s size 9 and a US women’s size 11. In the UK, it is a size 8. This is a very common size for men but is considered a larger size for women.

Here is the quick breakdown to remember: EU 42 = US Men’s 9 = US Women’s 11 = UK 8. You will see this number printed on the label of most European shoe brands, but it is not a universal standard. Different brands and different shoe types (like heels vs. sneakers) will fit differently even if they say 42.

How EU Sizing Compares to US and UK

The European sizing system is based on the length of the foot in centimeters, called the Paris point. One Paris point equals two-thirds of a centimeter. This is why EU sizes do not have half sizes. You are either a 42 or a 43. This is different from US sizing, which uses inches and includes half sizes.

To get the most accurate conversion, measure your foot. Place your heel against a wall on a piece of paper. Mark the tip of your longest toe and measure the distance in centimeters. A foot that measures 26.5 cm to 27 cm typically corresponds to a size 42. If your foot is 27.5 cm, you will likely need a size 43.

Be careful with women’s conversions. Many charts say EU 42 is a US Women’s 11, but some brands will label it as an 11.5. Always check the specific brand’s size chart. When in doubt, look at the length in centimeters because that measurement does not lie.

Men’s Size 42: The Universal Sweet Spot

For men, a size 42 is the most common size sold globally. If you wear a US 9, you are in the middle of the bell curve. This means you have the easiest time finding shoes in stock. You will rarely have to order online because stores will almost always have your size in the back.

Because it is so common, you have the luxury of buying shoes that are slightly snug. Leather shoes, like dress shoes or boots, will stretch about half a size with wear. If you are between a 41 and 42, you should size up to a 42 for leather footwear. For canvas shoes like Converse, they run large, so a 41 might be better if you have a narrow foot.

For athletic shoes, stick to a true 42. Running shoes should have a thumb’s width of space between your longest toe and the end of the shoe. If you buy a size 42 in a running shoe, you should not feel your toes hitting the front, even on a downhill run.

Women’s Size 42: The Big-Size Reality

If you are a woman who wears a size 42, you know the struggle of finding stylish shoes. This is the point where most mainstream women’s lines stop. You are shopping in the “extended sizes” section, which means your options are limited but growing.

You need to be strategic about what you buy. Avoid cheap fast-fashion brands because they often cut their size 42 shoes narrow. Look for brands that specialize in larger sizes, or buy from European brands like Gabor or Josef Seibel, which are known for wider and longer fits.

For heels, a size 42 is tricky. The heel-to-toe drop makes your foot slide forward. Look for pumps with a deep toe box or ankle straps to keep your foot secure. For boots, you have more leeway. You can wear thicker socks to fill out the space, which makes a size 42 boot very comfortable.

Why a Size 42 Fits Differently Across Brands

The number 42 is not a law of physics. It is a manufacturer’s guess. A size 42 in a Nike running shoe will fit completely differently than a size 42 in a Dr. Martens boot. This is because of the “last” — the plastic mold shaped like a foot that the shoe is built around.

Some brands use a narrow last, which means the shoe is tight across the ball of your foot. Others use a wide last. If you have wide feet, you should look for shoes labeled “W” or “H” for wide. In EU sizing, this is often indicated by a letter after the number, like 42 G (wide) or 42 F (normal).

Here is a quick guide based on common brands:

  • Nike and Adidas: Run true to size. A 42 fits a US 9 perfectly.
  • Dr. Martens: Run large. You might be a 41 in their boots.
  • Clarks: Run wide. A 42 fits like a US 9.5 in other brands.
  • Salvatore Ferragamo: Run narrow. A 42 might pinch if you have wide feet.

How to Measure Your Foot for a Size 42

Do not guess your size. Your foot size changes as you age. Your arches flatten, and your feet get longer and wider. Measure your feet at the end of the day when they are at their largest. Swelling is normal, and you want shoes that fit your swollen feet, not your morning feet.

Here is the step-by-step process to get your true size:

  1. Tape a piece of paper to the floor against a wall.
  2. Put on the socks you plan to wear with the shoes.
  3. Stand on the paper with your heel touching the wall.
  4. Mark the longest part of your foot (usually the big toe or second toe).
  5. Measure the distance in centimeters.
  6. If you are between 26.5 cm and 27 cm, you are a size 42.

Measure both feet. Your left and right foot are rarely the exact same size. Buy shoes that fit your larger foot. If one foot is a 41 and the other is a 42, buy the 42. You can always add an insole to the smaller foot.

Practical Tips for Buying a Size 42 Online

Buying shoes online in a size 42 is a gamble if you do not know the brand’s fit. You cannot try them on, so you need to be smart. The most important thing is to check the “Size Chart” link on the product page. Do not just look at the number. Look for the “Foot Length in CM” column.

If the brand lists 27 cm for a size 42, and your foot is 27 cm, buy it. If the brand lists 26.5 cm for a size 42, and your foot is 27 cm, size up to a 43. This simple check will save you from the hassle of returns.

Always buy from retailers with free returns. Even with the best research, shoes can fit weirdly. You need to be able to send them back without a fee. Also, check the return policy before you buy. Some sites do not accept returns on clearance or final sale items. Never buy final sale shoes in a size 42 unless you have already owned that exact model.

Frequently Asked Questions

Is a size 42 shoe the same as a size 9?

For men, yes. A European size 42 is a US men’s size 9. For women, it is a US size 11. This is the standard conversion, but you should always check the brand’s specific chart because some brands vary by half a size.

What foot length is a size 42?

A size 42 typically fits a foot that is 26.5 to 27 centimeters long. This is the measurement from your heel to the tip of your longest toe. If your foot measures 27.5 cm, you should order a size 43.

Is size 42 a large shoe size for a woman?

Yes, it is. In the US, the average women’s shoe size is around 8.5 to 9. A size 42 (US 11) is considered an extended size. It is not rare, but it is less common, so you will have fewer options in standard retail stores.

Do European sizes run smaller than US sizes?

Not smaller, just different. European sizes do not have half sizes. A US men’s size 9.5 is between a EU 42 and 43. If you are a US 9.5, you should try a EU 43 for a comfortable fit, especially in closed-toe shoes.
