The size of the belt depends on the waist circumference. Generally, men's waist circumference should be thicker, while women's waist should be smaller and more comfortable. Here are some sizes:
Men's belt:
2.1-2.3 feet should belong to the relatively thin category, with a total belt length (including the belt head) of about 100-105CM
2.4-2.5 feet should belong to the category of moderate stature, with a total belt length (including the belt head) of about 108-113CM
2.6-2.8 should belong to the category with a slightly larger waist circumference, and the total length of the belt (including the belt head) is about 115-118cm
2.9-3.1 feet should belong to the heavier type, with a total belt length (including the belt head) of more than 120cm
Women belt:
Here is the size required for a mid to low waist belt.
1.7-1.8 feet: small and thin, with a total belt length (including belt head) of about 88-95cm
1.9-2.0 feet: relatively moderate, with a total belt length (including belt head) of about 95-102 cm
2.1-2.2 feet: the total length of the belt (including the belt head) is about 100-105cm
2.3 feet or more; The total length of the belt (including the belt head) is more than 105CM
Generally speaking, many MM's waist circumference is 60-75CM, which is generally measured at a thin position on the waist. The belt is tied at a middle and low position, so the two girths cannot be equal. The girth of the belt is naturally a bit larger than the girth measured on your body with a ruler. If you want to buy a suitable size, you can also choose the belt size based on the length of the belt you currently use and the distance from the belt head to the hole you usually use.
