## Convert foot length in cm to shoe sizes and shoe size tables in cm

Updated on by Stefan Banse It is not only for babies that shoe sizes are determined based on the foot length in centimeters. The shoe size converter also works like this: First it calculates the corresponding foot length in cm based on the entered shoe size, in order to then convert this into the sizes of the other shoe size systems using the ISO formula.

### Calculation of shoe sizes in cm according to ISO / TS 19407: 2015

The foot length in cm is converted into the shoe size of the respective size system according to ISO formulas, i.e. into the EU, UK, US or Mondopoint system. The following shoe size tables for foot length in cm are also based on this ISO specification. The ISO (International Organization for Standardization) has defined the conversion of shoe size systems and thus issued this international pre-standard. However, there are often deviations from the theoretically calculated shoe sizes in cm. Shoes are therefore often smaller or larger, e.g. depending on the manufacturer or simply due to different standards.

### Basic information on converting shoe sizes into cm

All ISO conversion formulas refer to the foot length in cm. In the case of non-ISO-compliant size specifications, the inside length of the shoe in cm or the length of the last in cm is sometimes used as the reference size for calculating the shoe sizes. For international standardization, however, the foot length in centimeters or millimeters is the method of choice.

Usually the foot length in cm is used in the ISO formulas to calculate the respective shoe size. If you want to determine the foot length based on a shoe size, the corresponding ISO formula must be changed so that the result of the formula is the foot length in cm instead of the shoe size. This conversion of the conversion formulas is explained in detail in the examples below.

### Measure foot length in cm

To correctly measure the length of the foot, it is best to place a sheet of paper against a wall and place your foot on it so that the heel is directly against the wall and therefore against the edge of the paper. Now draw along the toes with a pen. It is important to hold the pen straight at a 90 ° angle. Then measure the length from the rear edge of the leaf to the longest toe. Please measure both feet as they can often be of different lengths. It is also better to measure in the afternoon, as the feet only reach their full size during the day.

### Shoe size table for converting foot length into cm for adults

Based on the technical specification of the ISO, the following shoe size table results for different foot lengths in cm. The appropriate shoe sizes of the individual shoe size systems are assigned to each foot length in cm.

### Shoe size table for converting foot length into cm for children

In contrast to adult sizes, the toe freedom is calculated a little differently in the conversion formulas for children. Instead of a surcharge of two shoe sizes, a surcharge of eight percent of the foot length in cm is used for children. In addition, in the UK and US systems, child sizes are numbered differently than the adult sizes. There, after 13 child sizes, the sizes for adults starting with 0 or 1 follow. Based on the ISO specification, the following shoe size table is therefore recommended for all children's shoe sizes.

In this ISO size chart for converting foot lengths into cm according to shoe sizes, some fields are not filled out. This is because, based on the official ISO formula, no exact value was determined in the respective other size unit at the relevant point. The shoe size converter for the foot length in cm also determines the corresponding rounded sizes for the fields that are still open. In the computer result for the info buttons, both the calculation and the rounding are explained in detail.

### Example 1: Calculating the foot length in cm based on the EU size

Ms. Wagner is a German shoe size 40 and would like to use this size to calculate your foot length in cm. For this purpose, the ISO formula for calculating the EU shoe size will be changed accordingly.

### ISO formula for calculating the EU size

EU shoe size = (foot length in cm + 2 × 0.667) / 0.667

#### Explanations

• One size corresponds to two thirds of an inch, i.e. 0.667 cm
• The sizes start at 0
• Two sizes of toe room, i.e. 2 × 0.667 cm, are opened.

### Changed formula for calculating the foot length

Foot length in cm = EU shoe size × 0.667 - 2 × 0.667

### Calculation of the foot length of Ms. Wagner

40,0 × 0,667 − 2 × 0,667 = 25.35 cm

With the help of this foot length in cm, the shoe sizes for the other size systems can then be calculated using the respective ISO formula.

### Example 2: Calculating the UK size based on the foot length in cm

Ms. Wagner's EU shoe size 40 corresponds to a foot length of 25.35 cm, as we saw in Example 1. Now we will calculate your corresponding UK shoe size based on your foot length. To determine Ms. Wagner's lower jaw size, the appropriate ISO conversion formula is first used based on her foot length. The calculation result is then rounded to the nearest whole or half size.

#### UK size formula

UK shoe size = (foot length in cm + 2 × 0.847) / 0.847 - 25

#### Explanations

• Each UK size is one third of an inch or 0.847 cm
• The first 12 sizes are not awarded
• The following 13 sizes are reserved for children's sizes
• The sizes for adults begin with size 1 following the children's sizes
• 25 sizes are therefore deducted from the formula
• Two sizes, i.e. 2 × 0.847 cm, are opened for toe space

Read more extensive information on UK shoe sizes here.

#### Calculating the UK size

(25.35 cm + 2 x 0.847) / 0.847 - 25 = 6.924 UK

#### Round the result

Rounded off to the nearest whole or half size, this gives Ms. Wagner Shoe size 7.0 UK
