Sock Size Chart – The full sock fitting guide for men, women and kids

Discover all info needed to get your perfect fitting pair of socks, the below Sock Size Chart. In the US, numerical sock size is essentially how long your foot is in inches. This means that a sock size is not shoe size, but how long your foot is in inches. When you see socks labeled “sock size 9-11” or “sock size 10-13”, remember it refers to your foot length in inches, not your shoe size. Whether you’re buying men’s, women’s, or kid’s socks, the base for finding the right size is to first measure your foot length. Fortunately, most sock brands use alphabetical sizing (S, M, L, and XL) in correspondence to shoe size to make it easy.

As a preferred type of sock, the knee high socks are are more concerned about fit when they have larger or more muscular calves. Some brands offer wide calf knee highs:

  • Standard knee high socks fit around a calf circumference up to about 18 inches (45 cm): Wide calf socks fit up to about 21 inches (53 cm)
  • Most wide calf knee highs are designed to stretch to fit all sizes

Kids sock sizes explained

All parents and caregivers know that kids’ sizes can be confusing, and there’s no exception with socks! Every brand has different size indications, such as small and large, youth and junior. Every child grows at a different rate.

There are three main categories of socks for kids:

  • Baby socks: for newborns up to about 1 year old. When in doubt, go bigger, allowing the baby to grow into the socks.
  • Toddler socks: for children between 1 to 4 years old who wear toddler shoe sizes 4 to 7.
  • Boys’ and girls’ socks:  for children between 5 to 10 years old who wear kids’ shoe sizes 8 to 13 and then on up to a size 3. By about age 10, most kids can fit into standard women’s socks.

  2. Stand When Measuring (this can be skipped for babies) When in a wheelchair, you don’t need to stand up while taking foot measurements
  3. Measure both feet Human beings rarely have similar feet (left or right). Take the measurement of your biggest foot to check sock sizes.
  4. Stand on your piece of paper Foot size measurement for wheelchair users can be done without standing
  5. Start drawing Put your pen or pencil 90° on the surface you’re drawing on, and move slowly around your foot.
  6. Measure the length of your feet Use a ruler to take measurements of the longest part of your drawing
  7. Find your width fitting by drawing Use a ruler to take measurements of the wides part of your drawing, closest to the toe area. Socks come only in 1 size, but than you know your size for shoe sizes as well

Types of socks

1. No Show Socks

No show socks only reach partway up the foot. This length is meant to be invisible, or minimally visible, while wearing shoes. No-show socks are used in athletics, and in fashion, as they allow more emphasis to be placed on an outfit.

2. Ankle Socks

Ankle socks are often used in athletics, or pair well with any ensemble, due to their subtlety. Ankle socks are lightweight; you can wear them comfortably with casual or formal attire. 

3. Micro-Crew Socks

Micro-crew socks are longer than an ankle sock but shorter than regular crew socks. They end above the ankle and below the mid-calf. They pair well with mid or high top shoes and help to prevent chafing from occurring around your ankles. Micro-crew socks are most commonly worn during hiking. They protect your ankles from sharp objects like rocks and plants and those pesky mosquito bites.

4. Crew Socks

Crew socks are cut between the ankle and mid-calf length, typically ending under the calf muscle. Crew socks are the most common length and pair well with any boot or shoe.

5. Quarter Length Socks

Quarter socks length means it’s slightly visible above the heel collar of your shoe. Quarter length socks are useful if you’re wearing mid or high shoes and you want to prevent chafing around your ankles.

6. Mid-Calf Socks

Mid-calf, or trouser socks are popular style for day-to-day wear. Along with knee high, mid-calf is a common length for men’s dress socks. Mid-calf socks are a winter go-to, as they offer more coverage. 

7. Knee High Socks

Knee high, or over the calf socks run to just below the kneecaps. They’re ideal for keeping your legs warm, pairing well with boots, dress shoes, and running shoes. For women, knee-high socks can also be an attractive complement to a skirt. Knee-length socks generally feature stay-up technology to prevent them from rolling down. 

8. Thigh High Socks

Also known as over-the-knee socks or O.T.K., this length is paired with skirts, shorts, dresses or longer tops. Thigh highs can be a suitable alternative to wear during the colder months, since they cover much of the leg. Expect the elastic around the cuff to be tight since it’s working to hold up more material.
