Find your Birkenstock size
Measure your bare foot heel-to-toe, standing, in the afternoon.
Enter your foot length to see your Birkenstock size.
Fit tip: Birkenstock runs large and comes only in whole EU sizes, so size down to the nearest whole size if between. Pick Narrow for slim feet.
How to measure
- Chest / bust: around the fullest part, keeping the tape level.
- Waist: around the narrowest part, usually at the belly button.
- Hips: around the widest part of your seat.
- Foot length: stand on paper, mark from heel to longest toe, then measure the line.
Use a soft tape over light clothing, snug but not tight.
Birkenstock size guide at a glance#
Birkenstocks come in EU sizes only, so you buy an EU 38, not a US 7. Every size maps to a foot length: women's EU 35 to 44 covers 22.5 to 28.5 cm (8.86 to 11.22 in), men's EU 38 to 50 covers 24.5 to 32.5 cm (9.65 to 12.8 in), kids' EU 24 to 37 covers 15 to 24 cm.
What size is 38 in Birkenstocks? EU 38 fits a 24.5 cm (9.65 in) foot: a women's US 7-7.5 or a men's US 5-5.5. By the same charts, EU 40 is a women's 9-9.5 or men's 7-7.5 (26 cm / 10.24 in), and EU 44 is a men's 11-11.5 or women's 13-13.5 (28.5 cm / 11.22 in).
How do Birkenstock sizes convert to cm? The Length (CM) column in each chart is the foot length that size fits, stepping up 0.5 to 1 cm per size: EU 39 fits 25 cm (9.84 in), EU 42 fits 27 cm (10.63 in). Measure heel to toe and pick the size equal to or slightly longer than your foot.
Men's Birkenstock size chart#
Birkenstock men's sizes run EU 38 to 50, fitting feet 24.5 to 32.5 cm (9.65 to 12.8 in). Each EU size covers a whole-and-half US pair: a 26 cm foot is an EU 40, listed as US 7-7.5. For other brands and systems, see the international shoe size conversion chart.

Women's Birkenstock size chart#
Women's sizes run EU 35 to 44, fitting feet 22.5 to 28.5 cm (8.86 to 11.22 in). The chart works the same way as the men's: measure your foot heel to toe, find that length, and the row gives the EU size with its US equivalent.
| Size (US) | Size (EU) | Length (cm) | Length (in) |
|---|---|---|---|
| 4–4.5 | 35 | 22.5 | 8.86" |
| 5–5.5 | 36 | 23.0 | 9.06" |
| 6–6.5 | 37 | 24.0 | 9.45" |
| 7–7.5 | 38 | 24.5 | 9.65" |
| 8–8.5 | 39 | 25.0 | 9.84" |
| 9–9.5 | 40 | 26.0 | 10.24" |
| 10–10.5 | 41 | 26.5 | 10.43" |
| 11–11.5 | 42 | 27.0 | 10.63" |
| 12–12.5 | 43 | 28.0 | 11.02" |
| 13–13.5 | 44 | 28.5 | 11.22" |
Kids' Birkenstock size chart#
Kids' sizes run EU 24 to 37, fitting feet 15 to 24 cm (5.91 to 9.45 in). The US column follows US children's sizing, so it counts up to 13.5 at EU 31 and restarts at 1 for big kids. The centimeter column avoids that confusion entirely: measure your child's foot and allow about half a centimeter of growing room.
| Size (US) | Size (EU) | Length (cm) | Length (in) |
|---|---|---|---|
| 6–6.5 | 24 | 15.0 | 5.91" |
| 7–7.5 | 25 | 16.0 | 6.30" |
| 8–8.5 | 26 | 16.5 | 6.50" |
| 9–9.5 | 27 | 17.0 | 6.69" |
| 10–10.5 | 28 | 18.0 | 7.09" |
| 11–11.5 | 29 | 18.5 | 7.28" |
| 12–12.5 | 30 | 19.0 | 7.48" |
| 13–13.5 | 31 | 20.0 | 7.87" |
| 1–1.5 | 32 | 20.5 | 8.07" |

| 5–5.5 | 36 | 23.0 | 9.06" |
| 6–6.5 | 37 | 24.0 | 9.45" |
Frequently asked questions#
How do I determine my Birkenstock size?#
Birkenstock sizes are based on the European sizing system. To find your size, measure your foot length from heel to longest toe and refer to the appropriate size chart. If you're between sizes, it's generally recommended to size up for a more comfortable fit.
What's the difference between regular and narrow widths in Birkenstock footwear?#
Birkenstock offers two width options: regular and narrow. The regular width suits those with average to wider feet, while the narrow width is ideal for slim or slender feet. Your foot should fit comfortably within the footbed without spilling over the sides.
Do Birkenstocks run true to size?#
Birkenstocks are designed to match your foot's natural shape, so they may feel larger compared to other brands. It's important to refer to the size charts and measure your feet to ensure an accurate fit.
Is there a break-in period for Birkenstocks?#
Yes, Birkenstocks may require a short break-in period. Initially, wear them for a few hours each day to allow the footbed to mold to your feet. Over time, they will become more comfortable as they adapt to your unique foot shape.
How should I adjust the straps on my Birkenstocks?#
Adjust the straps so they are snug but not too tight. Your foot should be secure, but you should still have some room to move. Over-tightening can cause discomfort and prevent the footbed from molding properly to your feet.
Will Birkenstocks make my feet spread out?#
Birkenstocks support natural foot alignment, which can allow your toes to spread to their natural position. This doesn't mean your feet will permanently widen, but they may feel more relaxed compared to wearing narrow-toed shoes.
Are Birkenstocks durable? How long do they last?#
With proper care, Birkenstocks can last for several years. The high-quality materials used in both the footbed and uppers contribute to their longevity. Regular cleaning and maintenance can extend the life of your sandals.
