What’s Your Motorcycle Helmet Head Shape?

What's Your Helmet Head Shape--blog

In today’s Tech Tips and Tricks episode, we will delve into the often misunderstood aspects of helmet sizing, head shape, and how they affect the fit of a motorcycle helmet. Many people make the mistake of assuming that measuring their head size is enough to find the perfect fitting helmet. However, there’s more to consider when choosing the right helmet, such as head shape and the helmet’s design.

Head Shape and Helmet Sizing

Let’s start with an example to illustrate the importance of head shape. Imagine three heads, each measuring 56 centimeters around. One may assume that since the measurements are the same, they would all fit the same helmet, but that’s not the case. The key difference lies in the head shape.

The popular head shape classifications are:

  1. Round: Think of an M&M candy.
  2. Semi-Oval: Similar to a peanut M&M.
  3. Long Oval: Resembling the shape of a Good and Plenty candy.

North Americans often have long and narrow heads, while Europeans and Asians tend to have rounder heads. Many helmet manufacturers in Asia produce helmets based on their local head shapes, which may not suit everyone globally.

Importance of Finding the Right Fit

Wearing a helmet that fits properly is crucial for safety. When a helmet doesn’t fit well, it can lead to gaps between the helmet’s EPS (Expanded Polystyrene) and your skull. In the event of an impact, the EPS should absorb and slow down the impact force before reaching your head and brain. However, if the helmet is too big, it won’t provide adequate protection, and your head may experience unnecessary movement inside the helmet.

Disregard the Letter Designation

Many riders get fixated on the letter designation (e.g., S, M, L, XL) and assume that they fit into a specific size category. However, this letter designation varies between brands and models and doesn’t guarantee a proper fit. The key is to focus on the actual fit and not the label.

The Importance of Trying Helmets On

To find the right helmet, it’s essential to visit a local store and try on different models. Helmet sizes and shapes can differ significantly among brands, and each helmet model may fit differently. By trying on various helmets, you can determine the best shape and size for your head.

Understanding Helmet Break-In

When trying on helmets, some riders may find the helmet uncomfortably tight, especially with premium brands like Shoei and Rye. However, it’s crucial to remember that helmets often break in and become more comfortable with time. Don’t be afraid of a snug fit; it’s better for your safety.


Choosing the right motorcycle helmet goes beyond just measuring your head size. Head shape plays a significant role in finding a helmet that fits properly and provides the necessary protection. Remember to focus on the actual fit, not the letter designation, and always try on helmets before making a purchase.
