Find Your Perfect Sock Size
Sock Sizing
The Perfect Fit Starts With the Right Size.
Your sock size shouldn’t be a guessing game. Our socks range from small to double XL, but the best way to know the perfect fit for you is to match your shoe size to the chart on the left. That way, you’ll know the size you select will give you the fit and feel you expect.
Between sizes? Go with your gut, but rest assured that your socks will still fit great. If you receive your order and find yourself wishing you’d gone up or down a size, just let us know. We’ll happily send you replacements for your preferred size.
Concerned about laundry mix-ups? All FITS® socks are coordinated by color and size, based on the colors you see on the size chart. So, you won’t have to worry about mixing up your sizes with the other FITS® wearers in your home. (But stray socks mysteriously going missing in the dryer? Unfortunately, we can’t help with that.)
The Light Hiker is perfect for everything from big adventures to everyday wear.
How Do You Determine Sock Size?
Sock sizes are typically measured in inches, not by your shoe size. So, a sock size 6-8 will comfortably fit someone whose feet are between six and eight inches long. However, at FITS®, we make it easy for you to choose the ideal sock size without having to measure your foot. Simply use our sock size conversion chart based on your shoe size to select the right fit for you.
How Do You Measure Your Foot for Socks?
To measure your foot for socks, measure the length from the heel of your foot to the tip of your longest toe. The measurement in inches correlates to your sock size. For example, if your foot is 10 inches long, a sock size 9-11 should fit you comfortably. At FITS®, you can skip this step and find your sock size based on your shoe size using our conversion chart.
What Is the Sock Size Conversion?
The sock size conversion refers to sock size compared to shoe size. While all companies may vary slightly on which size socks to purchase based on your shoe size, you can always measure your foot to find the right fit for you.
What is Sock Size to Shoe Size?
Because sock sizes are determined by the length of your foot in inches vs. your shoe size, shoe and sock sizes differ. The FITS® sock size to shoe size conversion is as follows:
- FITS® Sock Size Small = Shoe Size 3½ – 5½ men’s and 5 – 7 women’s
- FITS® Sock Size Medium = Shoe Size 6 – 8 men’s and 7½ – 9½ women’s
- FITS® Sock Size Large = Shoe Size 8½ – 10 men’s and 10 – 11½ women’s
- FITS® Sock Size Extra Large = Shoe Size 10½ – 12½ men’s and 12 – 14 women’s
- FITS® Sock Size Double-Extra Large = 13 – 15½ men’s and 14½ – 16½ women’s
Knowing this makes it easy to choose the ideal sock size based on your shoe size without measuring your foot.
What Age is Sock Size 9-12?
Sock sizes typically don’t correlate with age. For kids, age can be a general indicator of what size sock they’ll need, but everyone is different. An adult sock size 9-12 fits anyone whose feet are approximately nine to twelve inches long. For kids’ sock sizing, check with the company to find exact details to ensure your little one gets the perfect fit.

What are socks?
Socks are a clothing item that you put on your feet to make shoes more comfortable to wear and to help keep your feet warm in cold weather. As we know them today, machine-knitted socks were first produced in the late 16th century, though a pair of hand-knitted socks from 300-500 AD was found in Egypt (pictured below). Another function of socks is to absorb sweat, which allows it to reach the air and evaporate.

💡 The word sock comes from the Old English word socc, which means “light slipper”. Socc comes from the Latin word soccus, meaning a “light, low-heeled shoe”, which in turn comes from the ancient Greek work sykchos.
Socks have a nasty habit of getting lost. Find out where they might be hiding and how many you’ve lost over the years with our lost sock calculator.
How to use this sock size calculator??
Using this sock size calculator to find out “what size of socks do I wear?” is really simple. First, select whether you’re looking to size socks for an adult or a child. For adults:
- Select whether the socks are for a man or a woman. In the US, there is a slight difference in the shoe size system for each gender.
- Enter your shoe size in either the US, UK/AU, or EU shoe size system, depending on your preference.
- We will then display your sock size result in US sock size and general sock size (small, medium, or large).
If you wonder how to calculate sock size for children:
- Choose whether you want to use the age or shoe size of the child to size their socks.
- To size socks by age, enter their age in either months or years, up to 11 years old.
- For shoe size, enter their shoe size, either the US, UK/AU, or EU shoe size system.
- We will then display your child’s sock size in US sock size and size name.
US sock sizes – what size of socks do I wear?
US sock sizes mustn’t be confused with US shoe sizes. Sock sizes in the US are based entirely on the length of the foot in inches, while US shoe size is defined as three times the foot’s length in inches, minus 22 for men and 21 for women. You can learn more about shoe sizes by taking a look at our shoe size conversion calculator. Here, we will focus on how to calculate sock size based on children’s, men’s, and women’s sock size charts.
So, if you’re in the US, simply measure your foot length to the nearest inch (go up to the next inch) to get your US sock size. As we mentioned, this method will work for men, women, and children. So that’s how to calculate sock size in the US. Easy, right?
Socks in the US are generally offered in three sizes:
- 9-11 US sock size – small
- 10-13 US sock size – medium
- 14+ US sock size – large
Specialist socks, such as compression socks or tailored socks, might be offered in single US sock sizes. If you still aren’t sure “What size of socks do I wear?“, check it with our sock size calculator!

If you don’t know the length of your foot in inches and don’t have a tape measure handy, you can always convert from shoe size to US sock size. Our sock size calculator is also a sock size conversion tool that tells you your general sock size – small, medium, or large. This way of sizing socks is commonly used outside the US.
Here is the US sock size chart for men that this calculator uses (we also show UK and EU shoe sizes):
US sock size | General sock size | US men’s shoe size | UK men’s shoe size | EU men’s shoe size | |
---|---|---|---|---|---|
9-11 | Small | 4-7. | 3-7 | 35-39 | |
10-13 | Medium | 8-12.5 | 7-12 | 40-46 | |
14+ | Large | 13+ | 12+ | 46+ | |
💡 The UK and Australia use the same shoe size system.

There is a slight shoe size difference for women’s socks compared to men, which you can see in the chart below. If you wear a shoe size 10 or greater, you might also consider men’s socks, as there isn’t much practical difference and you’d get to choose from more patterns and styles.
Here is the US sock size chart (also for the UK and EU) for women that this sock size conversion device uses:
US sock size | General sock size | US women’s shoe size | UK women’s shoe size | EU women’s shoe size |
---|---|---|---|---|
9-11 | Small | 5-10 | 3-8 | 35-41 |
10-13 | Medium | 10. | 9-11 | 42-45 |
14+ | Large | 14+ | 12+ | 46+ |

There is no agreed standard when it comes to kid’s sock sizes. Sometimes they are sold by age, shoe size or in descriptive sizes (e.g. toddler). Always double check the sizing guide of the store or sock manufacture to see what system they use. Our calculator allows you to input the age of the child or get the sizing of kids socks by shoe size (for US, UK and EU shoe size systems). We used the following US sock size chart, as well as for the EU and UK, as a guide for this calculator:
Size name | US sock size | US shoe size | UK shoe size | EU shoe size | Typical age |
---|---|---|---|---|---|
Newborn | 0-4 | 0-1 | 0-½ | 15-16 | 1-3 mos |
Infant | 4-5½ | 1-3 | 1-2½ | 17-18 | 3-12 mos |
Toddler | 5-6½ | 3-6 | 2½-6 | 18-21 | 1-2 yrs |
X-Small | 6-7½ | 6-9 | 6-9 | 22-25 | 2-3 yrs |
Small | 7-8½ | 9-12 | 9-12 | 26-29 | 3-7 yrs |
Medium | 8-9½ | 12+ | 12+ | 30+ | 7-10 yrs |
From newborn babies to 10-year-old children, we’ve got it covered. Remember, though, when it comes to children’s sock sizes by age, some kids grow at different rates, so you might need a size above or below the recommended one. That’s why measuring your child’s feet might be a better idea to get the right size socks the first time.
As you can see from the chart above, once your child gets close to 10 years old, you probably want to start looking at small adult size socks. They also might appreciate more grown-up sock designs and patterns.
