A boot size chart matches foot length to size, and each full boot size adds ⅓ inch. A men’s 9 fits about 10.6 inches (27 cm), which is UK 8, EU 42 and women’s 11. Standard boot width is D for men and B for women. Women’s size = men’s size + 2.
This guide gives you men’s, women’s and kids’ boot size charts, plus a boot size conversion chart and a boot width chart. You’ll also learn how to measure at home and what to do when you land between sizes.
Repeat for the other foot and use the larger number.
How To Measure Your Foot And Calf For Boots
Width and instep: Measure across the widest part of your foot, the ball, and compare it to the width chart below. Also note your instep (the top of the foot) as high, medium, or low, since it affects how a pull-on boot feels
Best time to measure: Feet swell as the day goes on, so measuring late in the day is common advice, though morning works too if you stay consistent — measure at the time you’ll wear the boots most
Socks: Wear your boot socks while measuring, since thick socks change the fit
Calf (for tall boots): Wrap a flexible tape around the fullest part of your calf, over the socks you plan to wear. A 15.5 inches or more measurement usually means sizing into a wide-calf boot
Boot height: Measure from the floor up to where you want the boot to end
FAQs
Is a boot size the same as a shoe size?
Not always, because boots use brand-specific lasts and don’t flex like sneakers, so check each brand’s chart.
How do I know my boot size?
Measure your longer foot from heel to longest toe, then match that length and your width to a boot size chart.
What is D and EE in boot size?
D is the standard medium width for men, and EE is an extra-wide fit two steps wider.
Is it better to size up or down for boots?
Size up if you’re unsure, since extra room is easier to fix with insoles or socks than a tight fit.
