US to EU Shoe Size Chart
US to EU shoe conversion is useful for international shopping, but EU sizes do not always map cleanly to one US size. Some brands publish single EU values, while others use ranges or foot length measurements.
Adult men: US to EU
| US | UK | EU | Foot length |
|---|---|---|---|
| 6 | 5.5 | 39 | 23.5-24.0 cm / 9.25-9.45 in |
| 7 | 6.5 | 40 | 24.5-25.0 cm / 9.65-9.84 in |
| 8 | 7.5 | 41 | 25.3-25.8 cm / 9.96-10.16 in |
| 9 | 8 | 42 | 26.0-26.5 cm / 10.24-10.43 in |
| 10 | 9 | 43 | 26.8-27.3 cm / 10.55-10.75 in |
| 11 | 10 | 44 | 27.6-28.0 cm / 10.87-11.02 in |
| 12 | 11 | 45 | 28.4-28.8 cm / 11.18-11.34 in |
If your US size is between rows, look for the brand’s centimeter measurement or try the nearest half size if offered. Athletic shoes may fit differently from dress shoes or boots even when the label size is the same.
Adult women: US to EU
| US | UK | EU | Foot length |
|---|---|---|---|
| 5 | 3 | 35-36 | 22.0-22.4 cm / 8.66-8.82 in |
| 6 | 4 | 36-37 | 22.8-23.2 cm / 8.98-9.13 in |
| 7 | 5 | 38 | 23.5-24.0 cm / 9.25-9.45 in |
| 8 | 6 | 39 | 24.3-24.8 cm / 9.57-9.76 in |
| 9 | 7 | 40-41 | 25.1-25.6 cm / 9.88-10.08 in |
| 10 | 8 | 41-42 | 25.9-26.4 cm / 10.20-10.39 in |
| 11 | 9 | 42-43 | 26.7-27.2 cm / 10.51-10.71 in |
Women’s EU conversions often appear as ranges such as 36-37 or 40-41. Treat the range as a signal to verify the exact product chart rather than forcing a precise match.
FAQ
Why are some EU sizes shown as ranges?
Different brands round EU labels differently, especially around half sizes. A range is safer than pretending there is one universal answer.
Should I size up for sneakers?
Only if the brand notes, your width, socks, or intended use support it. Do not size up automatically without checking foot length and fit comments.
What if my feet are different sizes?
Use the longer foot as the starting point and consider insoles, lacing, or width options for the smaller foot.
Data scope and limitations
These size tables are common reference ranges compiled for general guidance. They are not an official standard from any brand, retailer, marketplace, country, or regional sizing authority.
Use them to narrow your starting size, then confirm with measured foot length, the specific brand’s size chart, the shoe model’s fit notes, width options, and the return policy.
Fit Check Before You Convert Sizes
Shoe conversion charts are useful, but they are only a starting point because brands build shoes on different lasts. Measure both feet near the end of the day, when feet are usually slightly larger, and compare the longer foot with the size chart for the exact brand or retailer. If one foot is larger, size for the larger foot and use lacing, insoles, or socks to fine tune the smaller side.
Foot length is not the only fit signal. Width, toe shape, arch height, heel hold, sock thickness, and the intended activity can change the best size. Running shoes often need more toe room than dress shoes. Children's shoes need growth room, but too much extra length can cause tripping and rubbing. When buying online, check return rules before ordering a size that is between two systems.
Worked Example and Common Mistakes
Example: a foot measures 25.7 cm. One chart may point to a US men's 8, while another brand suggests 8.5. Instead of treating the conversion as absolute, check the brand's centimeter or mondopoint value, read whether the shoe runs narrow, and decide whether thick socks or sport movement require extra room.
- Do not convert from an old shoe label if that shoe already fits poorly.
- Do not assume US, UK, EU, and CM sizes convert perfectly across brands.
- Measure children more often because growth can change fit quickly.
- Use width guidance when the toes feel cramped even at the right length.
Brand and Use-Case Adjustment
After converting a size, adjust for the shoe type and brand. Athletic shoes, boots, sandals, heels, and children's school shoes all fit differently even when the label shows the same size. A running shoe may need extra toe room for foot swelling, while a dress shoe may need closer heel hold. For children, growth room should be enough to last but not so much that the shoe bends in the wrong place.
Use reviews carefully. Comments like “runs small” are useful only when paired with foot shape, sock type, and model. If the retailer provides centimeter measurements, prioritize those over broad country-to-country conversion tables. When possible, compare with a current shoe from the same brand and similar style.
- Measure both feet and use the larger foot.
- Check width as well as length.
- Consider socks, insoles, and activity type.
- Keep return windows in mind for online purchases.
Sizing Scenarios for Online Shoe Orders
Shoe conversion works best when the chart is paired with a fit scenario. A running shoe may need extra toe room for swelling and downhill movement. A dress shoe may need closer heel hold and a different width. A sandal may expose whether the foot sits correctly on the footbed. Children's shoes need growth room, but too much extra length can make walking clumsy.
Measure both feet while standing, then use the longer foot as the starting point. If one foot is wider, has a bunion, or uses an orthotic, width and volume may matter more than a half-size conversion. For brands that publish centimeter or millimeter foot length, use that value before relying on broad US, UK, or EU equivalents.
When ordering online, compare the converted size with reviews from people who mention foot width and shoe model, not just “runs small.” Keep the return window in mind and try shoes indoors with the socks or insoles you plan to wear. If the toes touch, the heel slips badly, or the widest part of the foot does not match the widest part of the shoe, the converted size is not the right fit.
Detailed Us To Eu Shoe Size Planning Review
This shoe size conversion guide page should be used as a practical decision review, not just a quick lookup. Start by writing down the real measurements, product limits, room constraints, material condition, route, or usage pattern that applies to us to eu shoe size. Then compare the recommendation with the exact item or space involved. The most common mistakes happen when a user copies a standard size, bag count, clearance, capacity, or placement rule without checking the tightest real-world constraint.
For us to eu shoe size, the final choice should leave room for tolerance. Products vary by brand, rooms are not always square, material can be damaged or irregular, and installation often needs hand clearance, access space, or a safe working margin. If the result is close to a limit, do not treat the calculator as permission to force the fit. Recheck the smallest measurement, compare the manufacturer's instructions, and choose the option with enough buffer for delivery, use, cleaning, maintenance, and future adjustment.
Before You Commit
- Confirm the source measurements with a tape measure, product manual, label, policy page, or final public URL where relevant.
- Test the choice physically when possible by marking a footprint, checking a sample, printing a proof, packing a trial box, or dry-fitting a part.
- Keep the result and assumptions together so the decision can be reviewed before purchase or installation.
- Use qualified guidance for electrical, plumbing, structural, code, medical, food safety, or other safety-sensitive work.
US to EU Shoe Size Chart Decision Margin
For US to EU Shoe Size Chart, review the shoe fit check with a margin-first mindset. List foot length, width, sock thickness, brand chart, shoe type, and return policy, then decide which one controls the final choice. If the controlling detail is uncertain, the page should push the user toward another measurement pass rather than toward the largest option that appears to fit.
The practical check is to measure both feet and compare the longer foot with the brand chart. Keep a note of what changed the decision: a tighter clearance, a different product sheet, a return-policy limit, a delivery problem, a maintenance need, or a normal-use movement path. That note makes the result easier to verify and more useful than a single isolated number.
- Identify the one measurement most likely to make the plan fail.
- Compare the preferred option with a smaller or more adjustable alternative.
- Save the final assumption with the sketch, label, photo, or specification sheet.
