Size Guide
SHOES
We are currently using Asian/European sizing for our footwear. To find your best fit, follow these steps:
-
Measure your foot
Place the back of your foot against a wall on level ground. Then measure the distance from point A to B.
The distance between A and B is the length of your feet. -
Select your size
Refer to the size conversion chart below and select the size closest to the length of your feet.
| Size | ASIA / EU | US | UK / IN | JP / MX | KR / CN | Length of Foot (CM) |
|---|---|---|---|---|---|---|
| S | 34 | 4 | 1 | 22 | 220 | 21.7 |

Size Chart for Adults
- CHARLES & KEITH uses Asian/European size for its footwear collection.
- If both sides of your feet are different in length, we recommend you select a shoe size based on the longer side.
- The current recommended size chart does not include half size recommendations. We suggest you select the shoe size based on the length closest to your feet measurement.
- Please note, foot length is not equivalent to shoe length.
- Shoe comfort is dependent on a combination of factors such as size, design/cutting and heel height. For example, shoes that are of the same size, but are different in design/cutting, may not give you the same level of comfort.
- These are recommended guidelines to get you the best possible fit for CHARLES & KEITH footwear collections only.
BELTS
Refer to the size chart below and select the belt size closest to the length of your waist/or hip, according to the belt type.
| TYPE | SIZE | WAIST |
|---|---|---|
| HIGH WAIST | S | 65cm/25.63" |
| M | 75cm/29.5" | |
| L | 85cm/33.5" | |
| MID WAIST | S | 70cm/27.5" |
| M | 80cm/31.5" | |
| L | 90cm/35.38" | |
| LOW WAIST | S | 80cm/31.5" |
| M | 90cm/33.38" | |
| L | 100cm/39.38" |
- This size chart is based on the belt type and can vary when worn at a higher or lower level.
- The size of a belt indicates the measurement from the buckle prong (or other methods of closure) to the middle hole of the belt.
- These are the recommended guidelines to get you the best possible fit for CHARLES & KEITH belt collections only.
