The word "size" is usually used to define the size of the frame of a bicycle or snowboard. When selecting both devices, the person's height is used, therefore the size is called the size. You can find out the size that suits you on your own, or you can contact a consultant in the store to find the right size.

Instructions
Step 1
To find out the size of a bicycle frame, you can use several methods. Measure your height and look at the special tables for matching the height and size of the frame in inches or centimeters. These tables can be found on the Internet, but they differ depending on the type of bike. So for a person 180-185 centimeters tall, a mountain bike frame should be 46-48 centimeters (18 inches), and a road bike frame should be 58-61 centimeters. The method of selecting a size for growth is not very accurate, since it does not take into account the structure of a person.
Step 2
To know the size of your bike more precisely, measure the height of your crotch along the inside of your leg. This can be easily done with a level and a tape measure; the level can be replaced with a book or something similar. Take off your shoes and stand on a flat surface. Clamp the level (book) between your legs, slide it gently forward. Measure the distance from the floor to the top of the level. It is advisable that someone help you with the measurements. Write down the value in centimeters.
Step 3
If you are going to choose a road bike, multiply this value by 0, 665. This is the theoretical frame size. To find the size for a triathlon bike, subtract three centimeters. For trekking and touring bikes, multiply crotch height by 0.66 for centimeters or 0.259 for inches. To get the size of a mountain bike frame, multiply the crotch height by 0.226 to get the value in inches. If you multiply by 2.54, you will know the size of the frame in inches.
Step 4
All of these methods help to find out the theoretical size, which is useful if you buy a bike from an online store, for example. But the easiest and best way is to choose the size of the frame practically - to sit on the bike, ride. In this case, choosing a size is very simple: there should be a distance from the palm of a person between the frame and the crotch.
Step 5
The size of a snowboard is its size from nose to tail. The stability of the ride depends on the correct selection of the size. Find out your weight and height. Determine your base size if you are going to ride at low speed on fairly gentle slopes. To calculate the size for men, multiply the weight (in kilograms) by 0.3 and add 136. For women, the formula is: multiply the weight by 0.4 and add 127.
Step 6
If you are going to ski on more difficult slopes, add 2-3 centimeters to the resulting size, for mountains you need to add 6-9 centimeters. The size of a snowboard also depends on a person's physique - for thin people, you need to add two centimeters to the base size, and for overweight people, you need to subtract two centimeters. Riding experience also matters - beginners should take two centimeters away from the base size.
