Shoe Size System

The History Of Shoe Size:

“Paris Point” was determined in the mid of 19th century in France as a standard for measuring shoe sizes. Paris Point was originated from the original stitching length of a sewing machines’ double seams, equating the 2/3rd’s of a centimeter, i.e., 6.67mm. It then spreads around Europe gradually. The system of measuring a shoe is the same as it was centuries ago. 

The only difference is that now the Paris Point is contemplated in Europe as the standard shoe size system. It is also known as the European size, EU size, German size, or the French size. The measurement makes a metric system using centimeters. Only Britain uses the measurement in inches with its own measurement system.   

The English measurement system is the oldest official system worldwide. It is based on inches, typically in Anglo-American countries, unlike that of the metric system for measuring shoes in the European region. During those times, the instruments for measurements were very expensive and were not available for everyday use. 

The measurement system was introduced by Edward II, the king of England, in 1324. He used barleycorn as the smallest unit of measurement in Britain and equalized one inch with three barleycorns placing lengthways, one inch = 2.54 centimeters in metric terms. The English measurement of shoe size is labeled as UK (for the United Kingdom) size.

The Paris Point measurement of shoe sizes was numbered uniformly. In contrast, the English method was complicated due to the distinguished sizes of children and adults.

The US system of a shoe size measurement, introduced in the mid of19th century, is based on The UK system of shoe measurement, with a difference of scale starting at 3 11/12₺, whereas Paris Point is that of 4₺, and child-size begins from 0, which is equalizes 15 of Paris Point. The US measurement of shoe size is labeled as US (for the United States) size.

2. English Shoe Size: Length in centimeter (= length of foot + 1.5 cm)/ 2.54 x 3 – 25.

3. UE Shoe Size: Length in centimeter (= length of foot + 1.5 cm)/ 2.54 x 3 – 24.

Oversized And Undersized Shoe:

Sizes that exceed the regular adult sizes are referred to as the “large sizes” or “out sizes.” In contrast, the smaller sizes below the average range are termed as “sub-sizes” or “small sizes. These sizes fall under special categories and are sold on various online platforms for making the search easier for their customers.

The human body’s base is the feet, as it helps maintain the balance of the body. Taller individuals need extra support for keeping the balance and managing the weight of their bodies. Hence, taller individuals’ feet size is bigger. These individuals’ height-to-foot ratio is roughly considered 6.6:1, i.e., a man with a 6.6″ height will have a foot length of 1-inch.

Our feet expand and grow with age, which affects the size of the shoe. Some factors contributing to larger shoe sizes are weight gain and loss of elasticity in ligaments and tendons.

In contrast, the average size for men shoe in America is 10.5. The difference between each size is about an inch. The new size number labeled for men in shoe size number 10 is now size 8. 

The shoe size also varies according to the region. As instanced by the US, the shoe sizes range from 32 – 50, equalizing shoe sizes 0.5 – 15.5. Hence, the average shoe size for men in Europe falls between 42 – 43, i.e., shoe size 10 in the US.

In the UK, the average shoe size for men is 9, which was eight a few years ago. This change is due to the rise in Obesity among individuals. Several experts in the Medical sector claim that hormones present in foods result in larger hands and feet.
