Whether you ride a bike, play softball, ride a motorcycle, or are gearing up for your first American football training, a helmet protects you from head injury. However, this device is only able to do its job if it is the right size for the head. The most common method to determine the size is to measure the circumference of the garment, but nothing can replace some tests done in the store with or without the help of a salesman.
Steps
Part 1 of 3: Measure the Head Circumference
Step 1. Evaluate the shape
You must consider the shape of the helmet before measuring the size. This is a very important detail, especially if you are looking for a model for the motorcycle. There are three main types that differ in shape: rounded oval, intermediate oval and elongated oval. This factor is decisive for most head protection devices, even if it is crucial for those for motorcycles and bicycles.
- The elongated oval models have an anterior-posterior length greater than the width.
- The intermediate oval helmets are slightly longer than they are wide and represent the most common shape.
- The rounded ovals have an antero-posterior and lateral dimension almost identical to each other.
Step 2. Wrap your head with a flexible tape measure
You should place it just above the eyebrows, making sure that it is well flattened against the skin and that it is not curled; it should be parallel to the ground around the entire circumference.
- It is not easy to take this measurement yourself, so ask a friend or family member to help you; alternatively, use a mirror to keep the tape measure aligned.
- If you are walking alone, cross the ends of the tape measure across your forehead to better read the value.
Step 3. Read the data on the meter
Detect several values and consider the largest one; write down all the measurements so you can remember them when you go to the store to choose the case.
Part 2 of 3: Try a Helmet
Step 1. Determine the type of helmet
The choice depends on the use you have to make of it. Each device is designed to withstand specific types of impact forces, which are unique to various sports. For example, don't wear a bicycle helmet for climbing or a baseball bat helmet for riding a motorcycle; in some cases, multiple models are available for the same sport, such as cycling.
- Mountain bike helmets are specifically designed to withstand possible impacts in unpaved environments.
- A racing bike helmet is lightweight and compact to offer aerodynamic benefits.
- The one for the BMX is built to withstand the stresses typical of a race of this type.
- A walking helmet does not have advanced technical features.
Step 2. Choose the right helmet size for your head circumference
Most are designed to fit different sizes within a certain range. Almost all manufacturers indicate compatible head circumferences on the helmet itself or on the packaging. You may notice the size symbol - small (S), medium (M) or large (L) - which refers to a table showing head circumferences.
Step 3. Try it
Wear it before you buy it to make sure it fits properly. It should cover both the forehead and the back of the head. If you shake your head with the helmet on, it shouldn't move in any direction. If someone puts a hand on the top of the helmet and tries to turn it around, the head should be forced to follow the movement; if the device rotates freely on the head, it is too loose.
Part 3 of 3: Inspect the Helmet Before Use
Step 1. Adjust the chin strap
If your helmet type is to be secured with this strap, check it before use. It must be snug without pinching the skin, it should also not interfere with breathing, with the ability to swallow or speak; at the same time, it shouldn't be so loose that you can put a finger between it and your chin.
Step 2. Try adding more padding
Many helmets have removable padding that can be washed after use for hygiene reasons. Sometimes, it is also possible to buy extra padding, but you should only do this if the helmet does not fit properly and snugly.
Step 3. Inspect it before using it
Check it or have it examined before wearing it; it must not be cracked, pieces of foam rubber must not be missing and there must be no damage whatsoever. If you notice any cracks, do not use the helmet; instead bring it back to the store or send it back to the supplier.
If you have to make it, don't ride a motorcycle, bike, and don't practice your sport until you are given a new helmet
Advice
- If possible, consult the manufacturer's size chart before trying on helmets.
- Most of the helmets are unisex, but some, especially the softball ones, are available in the female version with a hole in the back of the neck, to pass the hair in a ponytail.
Warnings
- Don't ride a bike, ride a motorcycle, and don't play a sport like baseball without a helmet or with one that isn't suitable for your head, or else you risk injury or even death.
- You should only use the right helmet for the size of your garment; it is dangerous to rely on the one suitable for another person.
