What head measurements do OMP Star helmet sizes cover?
A customer asked which head measurement goes with each OMP Star size. OMP’s current chart gives S as 55–56cm, M as 57–58cm, L as 59–60cm, XL as 61–62cm and XXL as 63–64cm. The larger-size labels on our product selectors currently differ, so send us your measurement before ordering if those figures do not agree.
- Manufacturer chart: XS to XXL
- Measure one finger above the eyebrows

Use OMP’s centimetre bands and check the selector before ordering

Our white, matt black and fluorescent yellow listings use the SC0-0617-A01 Star family code. Their selectors currently show L as 59cm, XL as 60cm and XXL as 61cm, which differs from OMP’s current chart above. Cameron’s fitting advice is to keep your tape reading and have us check the size label before you place the order.
Keep the actual reading, including any half centimetre. OMP advises choosing the larger size between two sizes. With these selector labels, have us confirm which exact option matches that advice before ordering.
How to measure your head for an OMP Star
Use a flexible measuring tape around your head, one finger above the eyebrows. Keep it level around the back and note the reading in centimetres. Measure again to check that the tape followed the same route.
Garreth would measure before choosing the colour and ask anyone helping to check that the tape stays level at the back.
Send Cameron your exact tape reading through the showroom contact page to check the model and the options before you order.
A tape measurement narrows the size choice; the fit still needs checking. The helmet should feel even around the head, with the retention system fastened as instructed by the manufacturer. A persistent pressure point is something to discuss during fitting.
Our motorsport helmet sizing guide explains the wider fitting checks. Garreth recommends checking those before committing to a size you have not tried.
Choosing an OMP Star colour
The white, matt black and fluorescent yellow Star listings are below. Garreth would sort the size and fit first, then choose the finish you prefer.
These Star listings show ECE 22.06 approval and are marked Non-FIA. Check your organiser’s helmet requirements before ordering. Our open-face FIA helmet guide explains the FIA choices if that is the specification you need.

Common questions about OMP Star sizing
What head measurement is a medium OMP Star?
M is 57–58cm on OMP’s current Circuit / Star chart, which agrees with the M option on the three shop listings.
What are the larger Star size bands?
OMP’s current chart lists L at 59–60cm, XL at 61–62cm and XXL at 63–64cm. The shop selectors currently carry different larger-size figures, so ask us to check your measurement against the label before ordering.
What if I measure between the printed bands?
Keep your exact reading for the fitting discussion, including any half centimetre.
Does the manufacturer list XS?
OMP’s chart includes XS at 53–54cm. The three shop listings checked for this guide currently show S to XXL as options.
Do other OMP helmets use the same chart?
Use OMP’s chart for the exact model, because its published rows distinguish different helmet families.
What if my measurement is outside this chart?
Tell us the measurement and intended use, or start with our larger-size helmet guide before checking the fit of the exact model.
Will this helmet suit my event?
Check the exact model’s approval against your organiser’s equipment requirements before ordering.
Our sizing advice
Garreth
Garreth’s top tip
Take the measurement before choosing a colour. I would also check the event’s helmet requirements at this stage, so you know the model suits the use you have in mind.
Cameron
Cameron’s fitting view
Send us the centimetre reading without rounding it to fit an option. I would check the label discrepancy before ordering, then check that the helmet sits evenly around the head when it is fastened.
Between two sizes on the OMP Star?
Send us your head circumference in centimetres, the exact Star version and your intended use so we can help check the size and fit.
