How to Measure Your FeetInches to Women's Shoe Size Conversion Chart
Women's Shoe Width Chart
Finding the right size shoe is more difficult than it should be, and wearing the wrong shoe size can have unfortunate consequences.
"If you regularly wear shoes that are too small or narrow for your feet, it can cause bunions, change the composition of your foot and affect your body’s alignment," Audree Lopez, a personal stylist and content creator, "Your foot widen with age and the arch may fall or your feet expand so wearing too small of shoes will lead to back and hip pain."
The thing is, there is no universal size chart that shoe manufacturers adhere to, and this lack of standardization is what accounts for inconsistencies in sizing (e.g. why you're an 8 in one brand and a 9 in another). Still, that doesn't mean all hope is lost. We spoke to Lopez for her tips on finding your true measurements and shoes that fit.
Keep reading for a step-by-step guide to measuring your feet in inches and finding your correct shoe sizes—in both men's and women's—once and for all.

How to Measure Your Feet
If a brand doesn't make their shoe size chart available, you may be tempted to write them a strongly worded letter (or let's be real, vent on social media), but we suggest measuring your feet instead. It's a method beloved by brands and wardrobe stylists alike. Lopez is a fan.
And it's not just foot length you should be after, but width, too. While not all shoes reference their width—often seen as letters that can be decoded to mean "narrow" or "wide"—they should. Knowing both length and width is the key to comfort, and with the help of some basic school supplies (we're talking, ruler, paper, pencil, etc.) it's pretty easy to figure out. :
- Stand on a level, flat surface so that all of your body weight is on your feet. The pressure makes them expand a bit.
- Tape a piece of paper to the floor. Put one foot on the paper, making sure that your full weight is resting on your feet; rock forward slightly. This helps your feet spread as they do naturally in shoes.
- Trace around your foot on the paper. Hold your pen or pencil as straight up and down as possible. (FYI: If you're having trouble balancing, ask your bestie to lend you a hand—that's what friends are for, right?).
- Flip the paper over, tape it down to the floor, and repeat step three with the other foot.
- On the tracings you've created, using a tape measure or ruler measure from your heel to the tip of your longest toe.
- Use the Women's or Men's Shoe Size Conversion charts below to convert the length of your feet to your corresponding shoe size.
- Using your tracings, measure the width of each foot at its widest point and record the larger of the two numbers.
- To compensate for the width of your writing utensil, subtract about 1/4 inch (1/2 centimeter) from that measurement.
- Check the Women's or Men's Shoe Width charts to determine your foot width.
Byrdie Tip
It's best to measure your feet at the end of the day—as that's when they're most swollen—and while wearing the type of socks you plan on wearing with your shoes.

Byrdie Tip
"Sometimes feet can change with age, pregnancy or injuries and feet can grow larger and wider," Lopez reminds, "One foot might be larger than the other so in that case, buy shoes that fit the larger foot
A Note About Width
Not to make things too complicated, but some manufacturers offer non-standard widths, which you'll see as combinations of the numbers and letters above. For example, 11EE is a bit wider than extra wide—by about 38/100 of an inch, to be exact. Generally, that's the difference between each successive letter width designation.
Trying It Out
So to put it all together, let's say you measure your foot's length as 9-1/2 inches long; that gives you a basic U.S. women's shoe size of 8. If you then measure the width at 3-15/16 inches, you come up with a wide ("D") width. That makes your shoe size 8D. Bingo!

Trying It Out
Let's make pretend that you've already measured your feet and they're 10.5 inches long and 4 inches wide. According to the men's size conversion chart, that would make you a size 9.5 men's shoe. Next, locate your 9.5 shoe size on the shoe width size chart and move across the corresponding row until you find the measurement that matches—or is closest to—your width of 4 inches.You'll find that it's 3 15/16 inches located under column "Medium (D)." That would mean your shoe size is 9.5D or just 9.5 since a medium width is considered "average."
Nothing Beats a Fitting
While our measuring guide and conversation charts are useful sizing tools—especially if you're shopping for shoes online—nothing beats trying on a pair in person (if you can). That's because the type of footwear (e.g. boots, loafers, heels) and its materials (leather vs. synthetic) will affect its fit and feel. So go ahead and give them a test run, walk, trot, dance—whatever moves you. In order to get the best idea of the fit, Lopez recommends wearing the type of socks you would naturally wear with the sneaker, loafer or boot. "Your feet naturally expand during the day so shop during the afternoon and account for your feet swelling if hot, bloated or during travel," she offers.
The Final Takeaway
Now that you have your foot size, write it down and commit it to memory. Even though we stand by our shoe measuring and sizing guidelines, there's no better way to get a real feel for how shoes fit than by actually putting them on and walking around a bit. So if you have the opportunity to try on a pair of sneakers,boots,loafers, or what have you before buying them, do it.And if there's a handy dandy salesperson available to offer their help and expertise, take it. Lastly, if all else fails, never underestimate the power of a return policy.
