Why is Proper Helmet Fit Important?

Wearing a helmet that does not fit properly can be just as dangerous as not wearing one at all. A loose helmet can slide around on your head, leaving you vulnerable to head injuries. On the other hand, a helmet that is too tight can cause discomfort and even pain, which can be distracting while you are trying to concentrate on your activity. Proper helmet fit is important for your safety and comfort.

Different Types of Helmets

Before we get into how to fit a helmet, it is important to know the different types of helmets available. There are several types of helmets, including:

  • Bike helmets
  • Motorcycle helmets
  • Ski helmets
  • Skateboard helmets
  • Football helmets

Each type of helmet is designed to protect your head during a specific activity. It is important to choose the right type of helmet for your activity.

Measuring Your Head

Before you can choose the right helmet, you need to measure your head. To do this, use a soft tape measure to measure the circumference of your head, just above your eyebrows and ears. Take note of the measurement in centimeters or inches.

Choosing the Right Helmet

Once you have measured your head, you can begin the process of choosing the right helmet. When shopping for a helmet, look for one that:

  • Matches the type of activity you will be doing
  • Fits snugly but comfortably
  • Has a safety certification, such as DOT or Snell

Try on several different helmets until you find one that fits properly and is comfortable to wear.

Fitting Your Helmet

Now that you have chosen the right helmet, it is time to fit it properly. Follow these steps:

Step 1: Positioning the Helmet

Position the helmet on your head so that it sits squarely on top of your head. The helmet should cover your forehead, just above your eyebrows, and the back of your head.

Step 2: Adjusting the Straps

Adjust the chin strap so that it is snug but not too tight. The strap should be centered under your chin and fit snugly against your skin. Adjust the side straps so that they form a “V” shape under your ears. Make sure the straps are tight enough to keep the helmet in place but not so tight that they cause discomfort.

Step 3: Checking the Fit

Once you have adjusted the straps, check the fit of the helmet. Shake your head from side to side and up and down. The helmet should stay in place and not move around. If the helmet slides around, it is too loose and you need to adjust the straps. If the helmet feels tight or uncomfortable, it may be too small and you need to try on a larger size.

Common Fitting Issues

Sometimes, even after following the steps above, you may

encounter some fitting issues with your helmet. Here are some common issues and how to address them:

1. Helmet moves too much

If your helmet moves too much when you shake your head, the straps may be too loose. Adjust the straps and try again. If the helmet still moves too much, it may be too big for your head and you should try a smaller size.

2. Helmet is too tight

If your helmet is too tight and causes discomfort, it may be too small. Try on a larger size and adjust the straps accordingly.

3. Helmet sits too high or low

If your helmet sits too high or low on your head, it may not be the right shape for your head. Try on a different model or brand of helmet to find one that fits your head shape better.

Maintaining Your Helmet

To ensure that your helmet continues to fit properly and provide adequate protection, you need to maintain it properly. Here are some tips for maintaining your helmet:

  • Store your helmet in a cool, dry place, away from direct sunlight.
  • Avoid dropping your helmet or hitting it against hard surfaces.
  • Clean your helmet regularly with mild soap and water.
  • Replace your helmet if it becomes damaged or involved in a crash.
