A caliper has 2 spikes that you can move apart to measure the size of the skateboard wheels. You need to make sure that the spikes are moved far enough apart to fit the wheel in between them, and then you are able to see how big the wheel is. 

As the caliper spikes can be sharp, make sure that you don’t injure yourself when using them and you use them in a safe environment. The caliper measurement is the msot accurate measurement. 


You can use a ruler to measure the skateboard wheels by simply finding the center of the wheel and reading the millimeter measurement. If your ruler doesn’t have millimeters on it, you can convert centimeters to millimeters to determine the size.

What Sizes are Skateboard Wheels? 

Small Wheels: 48mm-51mm

Small skateboard wheels are popular for riding on flat surfaces. These size wheels were popular in the 1990s and are enjoyed by people who use retro skateboards.

Although these wheels are great for flat surfaces, they can become trapped in pavement cracks and affect your balance. However, the distance between the wheel and the board is larger, so there is less of a risk of stones becoming stuck and halting your ride. 

Medium Wheels: 52mm-54mm

Medium skateboard wheels are most popular for street and transition skateboarders as they can adapt to different surfaces.

They are small enough to smoothly ride on flat ground but also large enough to support the board when riding ramps or bowls. The medium wheels come in different designs so you can choose a set that complements your board. 

Large Wheels: 55mm-60mm

Large skateboard wheels give vert skateboarders more balance when riding steep ramps as they generate a lot of speed and help to keep the board steady.

Unlike smaller wheels, larger wheels are less likely to get stuck in pavement cracks, but the distance between the wheels and the board will be smaller which could result in small stones becoming stuck.

High durometers, usually 80A and over, are used for street skating as they are durable for performing tricks, and 75A and lower, is usually used for skating on flat surfaces. 

Measuring the hardness is important because you want to be sure that your skateboard is safe and stable to use for the purpose that you have it. If the wheels are too soft when you are performing tricks, it can impact your performance and put you at risk of injury. 

Having wheels that are too hard when cruising may result in a ride that is less smooth. Having softer wheels for cruising allows your board to glide over the surfaces and generate more speed as the wheels are lighter.

This is why it is important to not only measure the size of your wheels, but the hardness as well as the hardness greatly impacts your performance if not chosen correctly.
