How to measure your foot for size?
Before you get to selecting shoes, you first have to know your size. Even if the industry standard changes, it won’t help if you don’t know what the measurement of your feet even is. So let’s talk about how you can get the measurement for your feet.
Tracing your foot
Step 1: Take a paper (larger than your feet) and pencil. Step on the paper and ask someone to (or if you can do it yourself) trace an outline of your foot on the paper.
Step 2 : Use a measuring tape and measure, lengthwise/vertically, from your big two to your heel on the tracing of your foot. Take the measurements in Inches and Centimeters.
Step 3 : Unlike the length of your foot, the width isn’t going to be accurate if measured using the 2D tracing. So use the measuring tape and wrap it around the widest part of your foot at your bunion joint.
This will give you the width of your foot, note it down on the paper in Inches and Centimeters.
Now you can use these measurements to compare with size charts available online. Check your measurements against the sizes in the chart to see which size fits you. Additionally, you can also check the sizes of your shoes to get an idea of what sizes have been comfortable and uncomfortable for your wear.
Another way you can get your measurements is to order a Ritz stick from Amazon and use it to get a more accurate measurement.
FUN FACT: In 1913, Oliver Cornelius Ritz-Woller invented the ‘Ritz Stick’. It’s a scale with a fixed heel and a sliding stop for the toes that moves along the scale and was invented in the USA. These devices are still being manufactured today.
How shoe size is calculated
To answer the question of “what is the average shoe size for a woman ?” it is important to first understand that shoe size calculated worldwide varies by countries and manufacturers.
Many countries have their own measurement system that is based on traditional elements. Things that influence the difference between shoe sizes are:
- What the number for size measures exactly
- The unit for measurement used
- Whether the measurements start from 0 or 1
FUN FACT: The sizes of the left and right feet are slightly different but all shoes are sold in the same sizes because companies are not allowed to sell the same pair of shoes in different sizes.
The relation between shoe size against Height and Weight
There is data to suggest that height and shoe size are co-related. Shoe size goes up with height however, formal research does not show this consistency.
The reason for this difference in information is because the data will vary depending on who is asked and how the shoe size is measured. Additionally, height is strongly dependent on genetic factors which would explain the reason for mixed data.
When people buy shoes they also tend to buy sizes slightly larger than their feet, for comfort. This means there will be a difference between the actual foot size and the shoes purchased.
Weight directly does not impact foot size. But weight gain does affect your body’s strategy for storing fat across the body, which includes the feet.
So things like pregnancy, obesity, and swelling in feet due to injuries or medical conditions will affect the overall size that will be a comfortable fit when selecting shoes.
Women should expect and prepare for a change in foot size during pregnancy, as the weight gain or fluid retention in the body will probably create some swelling in the feet leading to a foot change.
During pregnancy, women should wear soft and comfortable shoes. There is a wide variety available with lots of cushioning and support.
