Birkenstock Fit Guide: Find Your Perfect Size 📏
Birkenstock footwear is beloved for its legendary comfort, ergonomic support, and timeless style — but getting the right fit is essential to enjoying every step. Unlike traditional shoes, Birkenstocks are designed with a contoured footbed that follows your foot's natural shape, which means the correct size should feel roomy yet secure. Let's walk you through how to measure your feet, choose the right size and width, and fine-tune the fit so your Birkenstocks feel amazing from day one.
📏 Step 1: Measure Your Feet (Yes, Really!)
Before you pick a size, measure both feet — because no two feet are exactly the same.
What you'll need:
- Two sheets of paper
- A pencil or pen
- A ruler
How to measure:
- Tape the sheets of paper flat on the floor.
- Stand with your heel gently against a wall and your foot flat on the paper.
- Mark the longest toe and the widest point of your foot.
- Measure from the wall (heel) to the longest toe — that's your foot length.
Tip: Always measure while standing — your foot expands slightly under full weight.
📐 Step 2: Use Birkenstock's Size Calculator
Once you have your measurements, use the Birkenstock size calculator on their fitting page to find your recommended size and width for both feet. Choose the size that fits your larger foot if there's a discrepancy.
Birkenstocks are listed in European (EU) sizes, and they also come in two widths:
- Regular – for average to slightly broader feet
- Narrow – for slender feet
If you're unsure between sizes, Birkenstock generally recommends sizing up rather than down — especially for sandals — since feet spread slightly when you walk.
👣 Step 3: Check the Ideal Fit
Once your Birkenstocks arrive, it's time for a quick in-shoe check:
Heel & Toe Space
- There should be about 5 mm of space at the heel between your foot and the edge of the footbed.
- You should have about 10 mm of space in front of your toes.
If your toes touch the edge or hang over, the size is too small. Too much extra space? The size might be too big.
Straps & Comfort
Adjust the straps so your foot feels secure — but not constricted. A good rule of thumb is enough room to slide a finger under the strap without discomfort.
🤝 Break-In Tips That Make a Difference
Birkenstock footbeds are contoured and supportive, which can feel unfamiliar at first. Wear your new pair for a few hours at a time during the first few days — this helps your feet gently adapt and the leather or straps soften for a personalized fit.
Quick Recap
- Measure both feet while standing
- Use the Birkenstock size calculator and chart
- Choose size based on your larger foot
- Check for proper toe and heel spacing
- Adjust straps for balance and comfort
- Break them in slowly
Final Fit Tip
Birkenstocks aren't meant to hug your foot like typical sneakers — they're designed for a slightly roomier, natural fit that supports your stride. When done right, they'll feel like they were made just for you.
