Things bikers need to know

When buying a helmet, one of the challenges every biker faces is finding one that fits their head shape. Everyone has a different biological structure, and therefore not every helmet will fit perfectly. So what's the solution? How do you choose the right helmet size? Let's find out in this article.

The shape of the human skull

Based on anatomical studies, the human skull can be divided into three main types:

Round Oval: This is a common skull shape among Asians. The distance from the middle of the forehead to the occipital bone (at the back of the head) and from one ear to the other are roughly equal.

Intermediate Oval Shape: This shape is commonly seen in Europeans. The distance from the forehead to the occipital bone is slightly longer than the distance between the two ears.

Long oval: This skull shape has a length from the forehead to the occipital bone that is much greater than the distance between the ears. This shape is common in people of African descent and neighboring regions.

The importance of understanding head shape and size.

Before buying a helmet, it's important to know your head shape and size. Each helmet brand has different styles and sizes, and even within the same brand, there are variations between models. Additionally, another factor to consider is the shell size.

Reputable brands typically produce helmets with 3-4 different shell sizes. For example, XS and S sizes might use the same shell, while M and L use different shells, and XL-XXL have yet another shell. Conversely, cheaper helmet models might only have 1-2 shell sizes, which can make the helmet look disproportionate. The thickness of the EPS foam padding inside the helmet will vary depending on the size, making your head appear larger if you have a small skull.

How to measure head size to choose a helmet

Measuring head size is very simple. You just need to use a measuring tape and wrap it around your head, from above your eyebrows to the occipital bone. For those with long or voluminous hair, tie your hair back before measuring to get the most accurate measurement, excluding the hair.

Choose a helmet based on size and style.

Currently, the market offers many helmet brands with different sizes and styles. When choosing a helmet, you need to consider two main factors: size and shape. Once you have enough information about your head size and know which style suits you best, you can confidently choose and buy a helmet, whether directly from a store or through online sales channels.
