How to choose a skateboard helmet for kids—size guide

Introduction

Hey there, friend! I get it—nothing stirs more emotion than seeing your kid take off on a skateboard for the first time, right? You watch them zip along, heart in your throat, thinking: “How do I keep them safe?” Today, I’m diving into how to choose a skateboard helmet for kids—size guide, just for you. I’ll walk you through measuring, fitting, safety certifications, and more. So grab a cup of tea, let’s dig in—and rest easy knowing we’ve got your child’s head covered.

Why Proper Size and Fit Matter

Kids’ Head Development & Safety

Kids’ brains and skulls are still growing—soft, shifting, and sensitive. A helmet that fits snugly helps absorb impact, just like seat-belt protection in a car crash. Studies show nearly 50 children per hour visit the ER for fall-related head injuries from wheels, and helmets can dramatically reduce the severity of those injuries.

Skate vs. Bike Helmets—Key Differences

You might wonder: “Can they just wear a bike helmet?” Reddit veteran skaters offer some wisdom: while it’s okay short-term, bike helmets don’t cushion the back of the skull, which is a common landing spot in skateboarding falls. Skateboard helmets are made to protect against multiple impacts and cover the back and sides more fully. A proper skate helmet also features thicker foam designed to rebound after gentle tumbles—bike helmets often can’t handle that repeat use.

How to Measure a Child’s Head Correctly

Tools You’ll Need

Soft cloth measuring tape (or a string + ruler)
Marker or note pad

Step-by-Step Measuring Process

Wrap the tape (or string) just above the eyebrows, around over the brow bone and around the biggest part of the back of the skull.
Keep the tape horizontal—not tilted; snug but not tight. Record the reading.
Repeat 2–3 times for accuracy.

Common Measuring Mistakes

Placing the tape too high or low
Measuring over bulky hairstyles (e.g. buns)—tie hair low or flatten it
Skipping brand-specific sizing charts—they vary widely!

Decoding Helmet Size Charts

Standard Youth Size Ranges

Youth Small: ~47–51 cm (18.5–20 in)
Youth Medium: ~52–56 cm (20.5–22 in)

Brand Size Differences

Different brands use different ranges. For example:

Triple Eight might label 46–52 cm as XS, while another brand calls that size “Small.” So always check their chart.

Age as a Rough Guide

Age labels are generic—two kids of the same age might have different head sizes. Don’t rely on age alone; measure to be sure.

The Essential Fit Test

The “4‑2‑1 Rule” (or 2‑Finger Brow Rule)

The helmet should sit about 2 finger widths above the eyebrows.
It should be level on the head—not tilted forward or backward.

Shake Test, Roll Test, and Chin Strap Check

Have your child shake their head vigorously—helmet must not slip or shift.
When they open their mouth wide, it should pull slightly downward—chin strap is snug enough but comfortable.
Straps should form a “V” under each ear, and buckle flat under the chin.

Pad Adjustments & When to Resize

Many helmets come with extra padding sets. If it’s loose, insert thicker pads—if too tight, swap thinner ones
If adjustment still doesn’t help, size up or down as needed.

Beyond Size—Key Helmet Features

Safety Certifications

Look for:

ASTM F1492: designed for skateboarding and multiple impacts.
CPSC: U.S. bicycle safety standard—work for skating only if it’s dual certified.
EN1078: European standard for bike, skateboard, roller use.

Best choice? Dual-certified helmets passing both ASTM F1492 and CPSC—so you’re covered for skateboarding and biking.

Shell & Liner Materials

Skateboard helmets use ABS or polycarbonate shells with EPS or EPP foam liners—durable and multi-impact capable. Some include MIPS or similar systems to reduce rotational forces.

Weight & Ventilation

Kids can complain if a helmet is heavy or too hot. Skate helmets tend to be heavier with few vents, but choose one with optimized airflow and lighter feel for comfort.

Adjustable Fit Systems

Look for models with dial-adjust rear cradles, interchangeable pads, or sliding depth adjusters—makes it easier to fit properly as they grow.

Troubleshooting Common Fit Issues

Too Loose?

Add extra padding or tighten the dial
Consider moving up half a size if adjustments aren’t enough.

Too Tight or Pinchy?

Swap to thinner pads
Make sure straps aren’t twisted or labeling systems aren’t over-tightened

Long or Thick Hair?

Tie ponytails low or flatten braids
Hair can lift helmet—ensure snugness by readingjusting fit before each ride.

When to Replace or Upgrade the Helmet

After a Crash or Impact

Skate helmets (ASTM) may survive minor knocks, but a hard crash usually means replacement.
Bike helmets (CPSC-only) must be replaced after any significant impact.

Every ~5 Years or After Growth Spurts

Helmet materials degrade over time—you should replace every 5 years maximum, or sooner if outgrown or damaged.

Signs of Wear

Any visible cracks, crushed foam, missing pads, or broken straps means it’s time to toss that helmet and get a fresh one.

Involving Your Kid in the Process

Let Them Choose Design & Color

Fun patterns, bright colors, or favorite characters help. When kids pick it, they’re WAY more likely to wear it gladly.

Modeling Behavior—Wear One Too

Kids do what they see. If you put on your helmet every time, they’ll follow suit—and feel proud doing it, too.

Make Wearing Fun & Habitual

Praise every time they zip it up. Maybe add a “helmet high-five ritual” before skating. Gear reward charts help—make helmet time a celebration.

Conclusion

So here’s the friendly lowdown:

Measure your child’s head accurately.
Decode the size chart—don’t rely only on age.
Perform the fit tests: brow rule, shake, strap.
Choose a dual-certified helmet (ASTM F1492 + CPSC).
Check materials, comfort, and adjustability.
Replace as needed—after impact or over time.
Let your kid help choose it—color, fit, fun.

Seeing your kid glide safely with a helmet that fits just right? That emotional relief—seeing them happy, confident, protected—it’s priceless. So grab that tape measure today, pick the perfect helmet, and let them ride with peace of mind.

FAQs

1. How tight should a kid’s skateboard helmet feel?
It should be snug, feel like a gentle hug all around, and not slip when they shake their head. If the straps are undone, the helmet stays firmly in place.

2. Can a bike helmet be used for skateboarding?
Only if it’s dual-certified to both ASTM F1492 and CPSC. Standard bike helmets often lack rear coverage and multi-impact foam needed for skate falls.

3. Do helmet sizes differ for boys and girls?
No—helmet size is based on head circumference, not gender. Always measure!

4. What if my child’s head size is between two sizes?
Pick the larger one if it can be snugged down with padding, or the smaller if they’re near the lower end and there’s enough adjustment.

5. How often should I check helmet fit and condition?
Do a fit check before each ride. Replace the helmet every 5 years, after a strong impact, or if it shows wear such as cracks or compressed foam.
