The best way to find your size is: get a piece of string that can span around the perimeter of your head. then, measure that length with a regular measuring tape. Amazon provides the different measures for the different sizes of helmets. I hope this helps.

Small. Medium will work, but it would pretty much be tightened all the way.

I purchased the small for my three year old and four year grandsons. The small is 4 to 5 for a small child not toddler. Not sure about medium but I can say the sizes are not men sizes.

It says M on the tag for Medium. It is a Christmas present for my 5 year old and I think it will fit him great! He wears a size 6 kids.... hope that was helpful!

Medium. If that doesn't work, contact their customer service dept. and they will exchange for one that will. Good luck and hope you are as happy with yours as we were!

A medium should be just right... It is 7 inches + or - with give in the fabric.

Definitely not a small. I think a medium would hit about right. Please let me know how it fits. I have a lot of questions this time of year and want to give good advice.

You need to measure his/her head. Small is 20 3/8"-21 5/8", Medium is 22"-22 3/4", and Large is 22 3/4"-24 3/8". Hope this helps.

MEDIUM. My dog is very similar size and I got the medium shipped to me a week or so again, and i've put it on him around this house, it fits fine! (link to my review: www.amazon.com/review/RD3WQPAMXT5E4/ref=cm_cr_pr_perm?ie=UTF8&ASIN;=B0081XIKYG)

My large is 58 cm. The Vilano website makes it appear that medium would be 54 cm.

I'm still awaiting the answer to the question in regards to the sizes. Plus there is a Medium and a 19cm Medium. What's the difference? Negative comment need not apply.

I assume Medium as in not narrow nor wide. I really cannot be sure, that is just my guess.

Yes medium would probably be too big I do believe they have different sizes though.

I would definitely go with medium. These are very tight. I was barely in the large range and there would be no way to get into the smaller ones for me.
