How to Measure Your Feet for Birkenstocks
Step 1: Prepare Your Setup
Find a hard, flat surface—like tile or wood flooring—up against a wall. Make sure there’s enough room to stand naturally and move a bit if needed. Grab a measuring tape, a piece of paper, and a pen if you’d like to trace your foot too.
Step 2: Stand Tall
Stand barefoot with your heels firmly touching the wall. Keep your feet flat, shoulder-width apart, and make sure your weight is evenly distributed. No tiptoes, no leaning; just a natural stance.
Step 3: Place the Measuring Tape
Lay the measuring tape flat on the floor, starting from the wall and extending out in front of you. Your heel should rest right at the “zero” end. Make sure the tape runs straight under your foot, all the way to your longest toe.
Step 4: Take the Measurement
Look straight down and note where your longest toe ends on the tape. That’s your foot length in millimeters. Make sure the tape is lying snug against your foot, not too loose and not stretched tight.
Step 5: Do Both Feet
Feet aren’t always twins because one might be slightly longer than the other. Measure both feet and write down each result. When in doubt, go with the measurement from the longer foot.
Step 6: When in Doubt, Size Up
If your foot length falls between two sizes, go for the larger one. That little extra room helps, especially since feet tend to swell during the day or when you’ve been on them for a while. A bit of wiggle room beats squished toes any day.
Step 7: Double-Check for Accuracy
Don’t just measure once and call it done. Repeat the process a couple of times to make sure you’re getting consistent results. Small measurement errors can add up to a big difference in how your shoes feel.
Step 8: Consider Foot Dynamics
Your feet change throughout the day—they swell, stretch, and shift based on activity, temperature, and more. To get the most realistic measurement, measure your feet in the late afternoon or evening, when they’ve naturally expanded a bit.
Step 9: Use the Official Size Chart
Now that you have your foot length, match it with a Birkenstock’s size chart. Don’t assume all brands fit the same—some run narrow, others wide. Manufacturer charts are your best bet for finding the right size for that specific style or brand.
Step 10: Test for Comfort
Birkenstock sizing is just the starting point. Once you try on the shoes, check how they actually feel. Walk around. Are your toes bumping the front? Is the heel secure? A good fit should feel comfortable right away with no break-in period required.
Now let’s talk about finding that perfect fit with Birkenstock – because comfort is key, right?
Birkenstock Fit Guide
Give Your Feet Some Room
When you’re figuring out your size, comfort is the top priority. Your feet should feel relaxed and supported in the footbed, not cramped or pushing up against the edges. There should be a bit of space in front of your toes and behind your heels so your feet can sit naturally, without any squeezing or crowding.
Try Them On and Walk It Out
Once you’ve figured out your Birkenstock size, it’s time to put them to the test. Slip on your chosen pair and take a short walk. Pay close attention to how they feel.
Your heel should stay in place without sliding, your toes should have room to spread, and the straps should feel secure without digging into your skin.
If something feels off (too tight, too loose), or just not quite right, it might not be the right size or width for you. But don’t sweat it. Birkenstock offers different sizes and two width options: regular and narrow.
Don’t Be Afraid to Adjust
It’s totally normal to try on a few pairs before you find the one that feels just right. Every foot is shaped a little differently, and that’s why Birkenstock gives you options to match your foot’s unique needs.
Once you’ve landed on the perfect size, you’re in for something special. One of the standout things about Birkenstocks is how the fit can completely shape your experience.
When the size is right, you’ll get that signature support and comfort they’re known for. But if the fit is off, even slightly, it can throw everything out of whack.
Let the Magic Footbed Do Its Thing
And here’s where the magic happens: the more you wear your Birkenstocks, the more the cork-latex footbed adapts to your feet.
Over time, it softens and forms a custom fit based on your unique foot shape, almost like it’s getting to know you. But that custom comfort doesn’t happen overnight.
Prep Before You Step
Before you start wearing them out and about, give your sandals a quick prep. Hold one in both hands, one hand at the toe and the other at the heel, and gently flex the footbed a few times. This helps loosen things up a bit and can make the break-in process smoother.
Next, open all the straps and slide your foot into the sandal. Adjust each strap so it’s snug but not tight. You want your foot to feel held in place, but still have the freedom to move naturally.
Ease Into the Comfort
As you begin breaking them in, take it slow. Wear them for just a few hours at a time over your first five or six outings. This gives your feet a chance to adjust to the structured footbed and the way the arch support and straps interact with your step.
Here’s how you can break in your Birkenstocks:

Birkenstock Sizing FAQs
What size is a 37 in Birkenstocks?
A Birkenstock 37 translates to a women’s 6 – 6 1/2.
Do Birkenstocks run big or small?
Generally speaking, Birkenstocks tend to run true to size. While there are exceptions where some styles may run larger, most Birlenstocks are true size. The key is to aim for a roomy fit – your toes and heel should have a bit of space, without touching the edges.
Remember, Birkenstock work in European sizes, so stick to your EU size for the best fit. Many Birkenstock styles come in two distinct fits: regular (M for Medium) and narrow (N). How can you tell which is which? Easy – just glance at the foot graphic on the footbed. If it’s filled in, you’ve got yourself a narrow fit. If it’s not filled, it’s a regular fit. Each Birkenstock model has its own unique feel, so don’t be surprised if you need to try a few styles to find your perfect match. Some styles may offer a snugger fit, while others give you a bit more wiggle room.
How do you measure your foot for Birkenstocks?
To measure your foot length accurately for Birkenstocks, stand barefoot against a flat surface with your heels touching the wall. Place a measuring tape under your foot from heel to longest toe, noting the measurement in millimeters. Repeat for both feet, choose the larger size if between sizes, and consider foot dynamics like swelling. Consult size charts for the right shoe size based on measurements, and test for comfort by trying on shoes before deciding.
Will I wear the same size in all Birkenstocks?
Your Birkenstock sizing may vary depending on the style you choose. Factors such as the silhouette, material, and footbed type can influence the fit. Unisex styles often run wider than others, while soft-footbed sandals may feel slightly narrower compared to classic-footbed sandals. Keep in mind that materials like suede have more flexibility and may stretch with wear, affecting the fit over time.
Should I get regular or narrow Birkenstocks?
Whether you should opt for regular or narrow Birkenstocks depends on your foot width. The regular fit is good if you have normal to wider-width feet as it’s going to offer ample space, which can be identified by the empty foot symbol on the footbed. On the other hand, the narrow fit is good if you have slim or narrow-width feet as it’s going to provide a snugger fit. You can spot the narrow fit by the colored-in foot symbol on the footbed.
How snug should Birkenstocks fit?
While the straps should offer a secure feel, they shouldn’t be overly tight. Instead, the primary source of support comes from the footbed itself, which is designed to mold to the contours of your feet over time. A good rule of thumb is to ensure the straps are snug enough to hold your foot in place without causing discomfort or restricting movement. Aim for a fit where you can comfortably wiggle one finger between the strap and your foot, ensuring that it’s not too tight. Similarly, there should be enough room for a finger to slide between the strap and your ankle, providing freedom of movement without sacrificing stability.
