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.

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.

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.
