Why Correct Helmet Size Matters

A helmet that fits well can save your life. It protects your head during crashes or falls. A helmet that is too big or too small won’t do its job. A loose helmet can move around and not protect your head. A tight helmet can be uncomfortable and may not absorb impact well.

How To Measure Head For Helmet: Step-by-Step

Measuring your head is easy. You just need a soft measuring tape and a mirror.

What You’ll Need

• Soft measuring tape (cloth tape measure)
• Mirror (to see what you are doing)
• A friend (optional, but helpful)

Step-by-Step Instructions

1. Get Ready: Stand in front of a mirror.
2. Position the Tape: Place the measuring tape around your head. It should be about one inch (2.5 cm) above your eyebrows and ears. This is the widest part of your head.
3. Keep it Level: Make sure the tape is level all the way around.
4. Measure: Pull the tape snug, but not too tight. Read the measurement in centimeters (cm) or inches.
5. Record: Write down the measurement. Measure a few times to be sure.

Tips for Accurate Measurement

• Hair: Measure your head with your hair as you usually wear it. If you wear a ponytail, measure with your hair in a ponytail.
• Help: Ask a friend to help. It can be easier to get an accurate measurement with someone else holding the tape.
• Double-Check: Measure more than once. This helps make sure you have the right number.

Helmet Sizing Chart: Find Your Fit

Once you have your head circumference measurement, use a helmet sizing chart to find your size. Different brands and types of helmets may have different charts. Always check the manufacturer’s chart for the specific helmet you want to buy.

Here’s a general helmet size chart:

Size	Head Circumference (cm)	Head Circumference (inches)
XS	51-52	20.1-20.5
S	53-54	20.9-21.3
M	55-56	21.7-22.0
L	57-58	22.4-22.8
XL	59-60	23.2-23.6
XXL	61-62	24.0-24.4

Note: This is a general chart. Always refer to the manufacturer’s specific helmet size chart.

Using a Helmet Size Chart

1. Find Your Measurement: Locate your head circumference measurement in the chart.
2. Find Your Size: See what size corresponds to your measurement.
3. Check the Brand: Always look at the size chart for the brand of helmet you want. Sizes can vary.

Different Types of Helmets and Sizing

Helmet sizing can be a little different depending on the type of helmet. Here are some common types:

• Bicycle Helmets: These are usually sized in centimeters or inches.
• Motorcycle Helmets: These are often sized as XS, S, M, L, XL, etc.
• Ski/Snowboard Helmets: Similar to bicycle helmets, they are sized in centimeters.
• Construction Helmets: Often have adjustable straps to fit a range of head sizes.

Helmet Fit Guide: Beyond the Size Chart

Just knowing your size isn’t enough. You also need to check how the helmet fits.

Checking the Fit

• Snug Fit: The helmet should feel snug but not too tight. It should not move around on your head.
• Level: The helmet should sit level on your head, covering your forehead.
• Straps: The straps should be adjusted so they are snug under your chin. You should be able to fit one or two fingers between the strap and your chin.
• Movement: When you shake your head, the helmet should stay in place. It shouldn’t slide forward or backward.

Signs of a Poor Fit

• Too Tight: If you have red marks on your forehead after wearing the helmet, it is too tight.
• Too Loose: If the helmet moves around easily, it is too loose.
• Pressure Points: If you feel pressure in certain spots, the helmet may not be the right shape for your head.

Additional Considerations for Finding Helmet Size

• Head Shape: People have different head shapes. Some helmets are rounder, while others are more oval. Try on different brands to see which shape fits you best.
• Padding: Helmets have padding inside. This padding can compress over time. You may need to replace your helmet after a few years.
• Adjustability: Look for helmets with adjustable features, like a dial at the back. This can help you fine-tune the fit.

Head Circumference Measurement: More Details

Let’s dive deeper into head circumference measurement to ensure accuracy.

Why Centimeters vs. Inches Matters

Most helmet manufacturers use centimeters for sizing. While inches are common in some countries, using centimeters provides a more precise measurement. If you measure in inches, convert it to centimeters using the formula:

Centimeters = Inches x 2.54

What If You Are Between Sizes?

If your head circumference falls between two sizes on the helmet sizing chart, it’s generally best to choose the larger size. You can then use the helmet’s adjustable features or add extra padding to achieve a snug fit. However, make sure the helmet doesn’t move around too much, as that would compromise its protective function.

Helmet Size Guide: Common Mistakes to Avoid

• Not Measuring at All: Some people guess their helmet size. Always measure your head.
• Measuring Incorrectly: Make sure the tape is level and snug.
• Ignoring the Brand’s Chart: Each brand has its own chart. Don’t assume sizes are the same across brands.
• Wearing the Wrong Type of Helmet: Use a helmet designed for the activity you are doing.
• Not Replacing After Impact: If you crash while wearing your helmet, replace it. The damage may not be visible.

Helmet Fit: What You Need to Know

The proper helmet fit is essential for safety. The helmet should cover your forehead, sit level on your head, and stay in place when you move.

Importance of Proper Ventilation

Besides fit, ventilation is a key factor. A well-ventilated helmet keeps you cool and comfortable. Look for helmets with vents that allow air to flow through.

Checking the Retention System

The retention system (straps and buckles) is what keeps the helmet on your head during a crash. Make sure the straps are adjusted properly and the buckle is secure.

Getting the Correct Helmet Size: Impact on Safety

A properly fitted helmet absorbs and distributes impact forces. A helmet that’s too large may shift upon impact, reducing its effectiveness. A helmet that’s too small may not fully cover and protect your head.

Care and Maintenance for Your Helmet

To ensure your helmet lasts and continues to protect you, proper care is essential.

Cleaning Your Helmet

• Exterior: Clean the outer shell with mild soap and water. Avoid harsh chemicals or solvents.
• Padding: Remove the padding and wash it by hand with mild soap. Let it air dry completely before reassembling the helmet.
• Straps: Wipe down the straps with a damp cloth.

Storing Your Helmet

• Avoid Direct Sunlight: Prolonged exposure to sunlight can degrade the helmet’s materials.
• Cool, Dry Place: Store your helmet in a cool, dry place away from extreme temperatures.
• Avoid Dropping: Dropping your helmet can cause unseen damage.

When to Replace Your Helmet

• After a Crash: Even if there’s no visible damage, the helmet’s structure may be compromised.
• Every 3-5 Years: Materials degrade over time, even if the helmet hasn’t been involved in a crash.
• If It Doesn’t Fit Properly: If the helmet becomes too loose or too tight, it’s time for a replacement.

Finding Helmet Size: Online vs. In-Store

Buying a helmet online can be convenient, but trying it on in person is always the best option.

Benefits of Buying In-Store
