Kids helmet safety: how to fit a helmet properly

Kids helmet safety: how to fit a helmet properly

Tiny Hearts

As a former paramedic, I've seen firsthand the difference a helmet can make. I've seen the relief on a parent's face when their child's helmet did its job, and I've seen what happens when there wasn't one on at all.

A helmet can reduce the risk of head injury by up to 85%. That includes concussions, skull fractures and brain bleeds, even at walking speed.


The 2V1 rule

A helmet only protects your little one if it fits properly. The 2V1 rule is a simple way to check every single time before they ride:

✅ 2 = fingers above the eyebrows. The helmet should sit level on their head, about 2 finger widths above the eyebrows. Not tipped back, not pulled down low. This covers the forehead properly.

✅ V = shaped straps around the ears. The side straps should meet just below the ear and form a "V" that frames it. This keeps the helmet sitting where it's meant to.

✅ 1 = finger under the chin strap. The chin strap should be snug, with room for only 1 finger between the strap and the chin. Any looser and the helmet can shift or come off in a fall.


Helmet buying checklist

When you're buying, here's what to look for:

👉 Australian safety compliance. Make sure it meets the Australian/New Zealand Standard (AS/NZS 2063:2008). That certification means it's passed proper safety testing.

👉 Correct fit. Run the 2V1 rule in the shop before you buy. A helmet that doesn't fit isn't doing its job.

👉 Adjustability. Look for adjustable straps and an internal sizing dial so it can grow with them.

👉 Comfort features. Padding, ventilation and a lightweight shell. A comfortable helmet is a helmet they'll actually keep on.

👉 Replacement guidelines. Replace after any significant impact, or every 3 to 5 years even if it looks fine. Check regularly for cracks and wear.


MIPS is next-level protection

MIPS stands for Multi-Directional Impact Protection System. It's a low-friction layer inside the helmet that lets it rotate slightly on impact.

Most real-life falls aren't straight down. Kids fall at angles, off scooters and bikes, twisting as they go. Those rotational forces are what MIPS is designed to reduce.

It's not essential, but if it's in your budget, it's worth it.


Helmets we love

These are the brands I recommend to parents:

Brand MIPS Why we love it
Micro Scooters ❌ Lightweight, great range of sizes from toddler up, and the patterns are a winner with little ones
Nutcase ❌ Chunky, durable and easy to adjust. Magnetic buckle means no pinched skin under the chin
Fox ✅ Built for bigger kids on bikes. Excellent coverage and rotational protection
Giro Scamp ✅ One of the few toddler-sized helmets with MIPS. Dial fit system and a flat back for kids still in a bike seat

Always double check the specific model you're buying. Some brands offer both MIPS and non-MIPS versions of the same helmet.


Our friends at Micro Scooters have given our community a code for 10% off.

A helmet is step one. You're step two.

A helmet does an incredible job, but it can't tell you what to look for after a fall, or what to do if your little one isn't responding. Our Baby & Child First Aid Course, designed by former paramedic Nikki Jurcutz, walks you through head injuries, when to call 000, CPR and the red flags to watch for, because in an emergency your brain falls to the level of your training.
