Sharing how to accurately measure your size for authentic Biti’s shoes.
Every brand has its own shoe sizing guidelines to help buyers easily choose the right pair of shoes. The same applies to Biti’s; if you can’t try them on in person at the store, you need to measure your foot accurately. This article will guide you on how to measure men’s, women’s, and children’s Biti’s shoe sizes simply, quickly, and correctly.
Instructions on how to measure Biti’s shoe size correctly.
To choose the right size shoes, you first need to know how to measure your foot size in relation to shoe sizes:
Step 1: Prepare the tools

You will need a sheet of white paper larger than your foot, a pen, and a ruler.
Step 2: Measure your foot size

- First, place the prepared white sheet of paper on a flat surface, then place your foot on it and hold it firmly in place.
- Use a pen to trace the outline of your foot. To ensure a clear outline, hold the pen straight and perpendicular to the paper. Trace precisely along the shape of your foot.
- You need to make sure you don’t move your feet while pausing to draw.
- Measure the size of the foot.
Step 3: Sketch the foot using straight lines.

Using a ruler, draw a straight line next to each side of the foot: along the toes, the heel, and both sides.
Step 4: Measure the length and width of your foot.

Using a ruler, measure the length and width of the square you just drew around the shape of the foot, then record the measurements.
Shoe size conversion chart
Understanding shoe size conversion charts will help you choose the best-fitting shoes. Below are the international shoe size standards and detailed conversion instructions. Specifically, there are four standard shoe size conversion guidelines:
Convert shoe sizes to standard UK sizes.
These are the commonly used shoe sizing charts in the UK. There are two ways to calculate standard UK shoe sizes:
- Calculate the size based on the last length of the shoe using the formula: UK Size = (3 x last length) – 25 (Last length is in inches)
- Calculate your size based on your foot using the formula: UK Size = (3 x foot length) – 23 (length in inches)
Convert shoe sizes to US standard sizes.
The US shoe size chart is commonly used in the United States, the Americas, and Canada. The formula for converting shoe sizes to standard US sizes is as follows:
- Men’s US size = (3 x last length) – 24 (last length in inches)
- Men’s US size ≈ (3 x foot length) – 22 (length in inches)
This is how to calculate men’s shoe sizes; for women’s shoe sizes, the following formula applies:
- Women’s US size ≈ (3 x foot length) – 20.5 (length in inches)
European (EU) shoe size conversion
EU shoe sizes are commonly used in European countries, most notably Germany, Spain, Italy, France, and some Middle Eastern and Asian countries. European shoe sizes are calculated using the Paris point system (1 Paris point = 2/3 cm). Specifically, you can apply the following formula:
- EU shoe size = 3/2 x last length (length in cm)
- EU shoe size = 3/2 x (foot length + 1.5) (length in cm)
Asian shoe size conversion chart (CM)
CM stands for centimeter, and it’s a commonly used shoe size in Vietnam and some East Asian countries (China, South Korea, Japan). The formula for calculating CM size is as follows:
- Size CM = foot length + 1.5 (length in cm)
