Measure	Value	Fit note
Foot length	27 cm / 10.63 in	Use the longer foot if left and right feet differ.
Nearest reference row	Mondopoint 270	Shown as nearest standard reference, not a brand guarantee.
Nearest-row difference	0 cm	If close to a boundary, compare both adjacent sizes.

Measure first

Measure heel-to-toe length while standing, then convert from centimeters or Mondopoint for the most stable result.

Fit varies

Shoe width, toe shape, socks, and brand lasts can change the best wearable size.

Adjacent sizes

If your foot length is between rows, try the nearest size and the next half size.

Conversion model

This converter uses foot length as the bridge between systems. Adult and kids charts are separated because US kids/youth labels do not align cleanly with adult men and women labels.

Footwear Fit Notice

Shoe size conversions are approximate. Brand lasts, width, toe shape, socks, foot volume, and country-specific labeling can change the best wearable size. Use the brand size chart and return policy before purchasing.

How to Use the Shoe Size Converter

Choose adult or kids/youth sizing, select the size system you are starting from, and enter the size or measured foot length. The converter maps the input to an estimated foot length and then shows nearby size equivalents.

For the most reliable result, measure foot length in centimeters or Mondopoint rather than converting from another regional label.

Step 1: Choose a profile
Select adult for US men/women sizing or kids/youth for children and youth labels.
Step 2: Select the starting system
Pick US, UK, EU, Japan/Korea, centimeters, or Mondopoint.
Step 3: Enter the size
Type the shoe size or foot length value you want to convert.
Step 4: Compare nearby rows
Review the nearest result and adjacent sizes before buying or fitting shoes.

How This Shoe Size Converter Works

Shoe-size systems are mapped through foot length. Mondopoint and Japan/Korea sizing are closest to direct foot-length systems, while US, UK, and EU labels are chart-based approximations.

The calculator chooses the nearest reference row, then shows adjacent rows so you can see when an input falls close to a size boundary.

Adult and kids/youth profiles are separated because US kids labels overlap numerically with adult labels and should not be interpreted through the same table.

Shoe Size Conversion Guide

Shoe Size Systems

System	Basis	Conversion note
Mondopoint	Foot length in millimeters	Most direct standard-style input.
Japan / Korea	Foot length in centimeters	Often closely tied to measured foot length.
US men / women	Separate adult labels	Women sizes are typically about one size higher than men for the same foot length.
US kids / youth	Child and youth labels	Use kids profile instead of adult profile.
UK	Adult and kids labels differ	Close to US men minus one in many adult chart rows.
EU	Continental European label	Unisex-style label, but fit still varies by brand.

Measuring for Fit

Step	What to do	Why it matters
Measure both feet	Use the longer foot.	Feet often differ slightly.
Stand while measuring	Put weight on the foot.	Standing length is more realistic than sitting length.
Measure late day	Feet can expand during the day.	Helps avoid selecting a size that is too tight.
Check width	Length conversion does not solve width.	Wide, narrow, and high-volume feet may need different lasts.
Try adjacent size	Compare nearest row and next half size.	Brand sizing and sock thickness can shift fit.

Foot length is the cleanest bridge between systems, but it is not the whole fit story. Width, toe box shape, foot volume, and activity type can all change the best size.

Need to convert a measured foot length first? Use the CM to Inches Converter or the MM to CM Converter.

Frequently Asked Questions

It converts each entered size to an estimated foot length, then maps that length to nearby US, UK, EU, Japan/Korea, and Mondopoint reference sizes.

Mondopoint is usually expressed in millimeters of foot length. For example, Mondopoint 270 corresponds to about 27.0 cm.

Shoe size labels do not fully describe width, toe shape, arch volume, materials, socks, or the brand last used to shape the shoe.

Use the adult profile for adult men and women labels, and the kids profile for children and youth labels. US kids labels overlap numerically with adult labels, so they need separate handling.

Measured foot length in centimeters or Mondopoint is usually more reliable than converting from another regional size label.
