Round head shape measurements

round head shape measurements

Identifying your head shape is the first step to finding the best round oval helmets. Specifically, if you suspect you have a round head, here’s how to measure it accurately:
Step 1: Gather your tools

  • To start, you’ll need a measuring tape, or you can use lace and a ruler. But this method is less precise.
  • A mirror would be a great addition.

Step 2: Find your reference points

  • Locate the broadest portion of your head in front of the mirror, over your brows and ears.

Step 3: Measure the circumference

  • Wrap the chosen measurement tool around your head over your brows and ears.
  • Maintain a level and parallel tape to the floor.
  • Make sure it’s neither tight nor loose — just snug enough.

Step 4: Record your measurement

  • Never trust your memory. You better put the measurements on the phone or a paper sheet.

Step 5: Assess the shape

  • Roundheads will be roughly the same size from front to rear as from side to side. So, you most likely have a round head shape if the dimensions are close.

Following these procedures will give you a comprehensive idea of your head shape, an important beginning point in your search for the fitting helmet adapted to your specific proportions.

Can a round-headed rider wear a helmet designed for other head shapes?

While a round-headed cyclist can use a helmet made for other head types, it is not advised. Helmets are designed to fit certain head shapes for the optimum fit, comfort, and safety. Wearing a helmet built for a different head shape may result in the following problems:

  • Comfort: During extended rides, a helmet intended for a different head shape may not fit correctly, causing pain, pressure spots, and even headaches.
  • Stability: Wearing the incorrect helmet form may cause instability and loss of control when riding.
  • Visibility: Improperly fitted helmets can impair your peripheral vision, which is essential for safe riding.

Can I wear a helmet with glasses comfortably if I have a round head shape?

Yes, even with a round head, you can easily wear a helmet with glasses. Many helmets are intended to suit motorcyclists who wear glasses. The main thing is to choose the right model, test it with your glasses, and enjoy your rides without experiencing the slightest discomfort.

Is it possible to modify a standard-sized helmet to better fit a round head shape

Modifying a standard-sized helmet to fit a circular head shape is not advisable. By picking the shape of the helmet correctly, you make sure that these precision-engineered products provide maximum safety and protection. Modifying a helmet might jeopardize its integrity and safety characteristics.

If you have a round head shape and find that standard-sized helmets are uncomfortable or do not fit correctly, you should look into helmets developed particularly for round head shapes. These models are designed with padding and curves to give riders a comfortable and secure fit with round heads. Investing in a helmet tailored to your head shape is the fastest and most dependable approach to ensure your riding safety and comfort.
