Buying a helmet online works well if you check five things before you order: that it's properly certified, that you've measured your head and matched it to that model's size chart, that the style suits how you ride, that the listing gives you real information rather than marketing, and that you can return or exchange it if the fit is wrong. Get those right and most of the risk of buying online goes away.
This guide puts everything in one place, in the order you'll need it.
1. Check certification first
In the US, a road helmet should meet DOT FMVSS No. 218. Look for it clearly stated on the listing and, when the helmet arrives, on the label inside and the sticker on the back of the shell. A very low price for a helmet that claims to be premium, a listing with no certification details, or a seller who can't answer the question are all reasons to walk away. Our guides to spotting a fake DOT sticker and the risks of counterfeit helmets go deeper.
2. Measure your head and read the size chart
Measure around the widest part of your head, about a finger's width above your eyebrows. Use that number with the size chart for the exact helmet you're looking at. Sizes differ between brands and even between models from the same brand, so don't order "your usual size." If you're between sizes, read what to do between two sizes.
Size is only half of fit. Head shape matters too. If previous helmets pressed on your forehead or temples, note that and look for a shape that suits you. Our online size guide covers measuring and charts in detail.
3. Choose the right style
- Full-face: most coverage, best for highway and all-round riding.
- Modular: full-face coverage on the move, chin bar flips up at stops. Good for commuting and glasses wearers.
- Open-face (3/4): lighter and airier, but no chin bar. Best for short city trips and scooters.
See full-face vs modular for the trade-offs.
4. Read the listing like a skeptic
A good listing helps you decide. A weak one tries to sell you a feeling. Look for:
- A real size chart in centimeters or inches, not just S, M, L.
- Clear features: shell material, visor type, whether the liner is removable, whether there's a sun visor or room for a headset.
- Photos from several angles, including the inside, the back and the strap. Studio photos with heavy editing can hide details, and colors on screen can look different from the real paint.
- Specific claims you can check. Be wary of vague promises like "maximum protection" or "ultra quiet" with nothing behind them.

5. Use reviews carefully
Reviews are useful for fit and comfort comments from people with heads like yours, noise reports on bikes like yours, and how the helmet holds up after months. Ignore reviews that only talk about delivery speed or look copied. One person's "too tight" may be another person's "perfect," so look for patterns.
6. Compare two helmets fairly
If two listings look similar, compare the things that affect you: certification, size range and shape, weight, visor and sun visor, liner, and the return policy. Two helmets with the same certification can still differ a lot in fit and comfort. A higher price doesn't automatically mean a better fit for you.
7. Think about the long run
- Spare parts: can you buy replacement visors, cheek pads and liners for this model?
- Warranty: what does it cover, for how long, and how do you claim?
- Accessories: if you'll add a Bluetooth headset, check for ear pockets and mounting space.
8. Check returns before you pay
Read the return and exchange policy before ordering, especially the time limit and whether you can return a helmet you've tried on indoors. Keep the box, bags and tags until you're sure. The FTC's online shopping advice is worth a look if you're buying from a site you don't know.
9. If your size is out of stock
Don't order the next size just because it's available. Wait for your size, ask when it'll be back, or choose another model that fits your measurement. A helmet in the wrong size is a waste of money.
10. When it arrives
- Check the certification label and that the size matches your order.
- Inspect the shell, visor and strap for damage.
- Try it on indoors for 20 to 30 minutes with the strap fastened before riding or removing tags.
- Save your order confirmation, photos of the labels and the warranty details.

Does helmet color matter?
Mostly for style, but bright colors and white are easier for drivers to see.
