• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Requesting Helmet Measurements for a New Database

Many people have difficulty finding a helmet that will fit them.

Please look at: http://www.wb2lua.com/marticles.htm

I have began a database of helmet measurements. This can help many people who do not have a nearby well-stocked store to find a helmet.

Please make the measurements and post them here along with the helmet brand/model and size.

I will add that information to the database.

Maybe not the best way to approach the issue as roughly 8 out of 10 riders are wearing a helmet at least 1 size too large for their head.

I hated that video. Absolute bull****! They are assuming that everyone has the same head anatomy. That is not true. Some people's head is large on top and tapers towards the jaw. Other's have the opposite shape. These designers should take a course in human anatomy.

True. There are variables that they do not get into on this video. It is basically designed to move people from the guessing zone towards a more accurate helmet sizing process.

But asking a group of people, 80% of who (or is it whom?) are probably wearing a helmet at least 1 size too large may not be the best informational source from which to build a database. That's all I'm saying.
 
My experience is that head shape is more important. While many heads are round, some are oval, and a few more are long-oval (like mine). IFor example, Arai caters to oval and long-oval heads. The fit of their Signet line is the best I've found. But they are pricey!

A common round-head helmet is tight on the front and back of my head, but loose on the sides. Some even wobble a bit side-to-side.

I think a database that indicates which helmets fit which shaped heads would be invaluable.

Funny you should say that, I've been using the webbikeworld guide for years. http://www.webbikeworld.com/motorcycle-helmets/motorcycle-helmet-shapes.htm

Cheek pads and cheek measurements are the least useful measurement, primarily because cheekpads are easily changed out for different thicknesses. The shape of the halo (the part around the circumference of at the temple) is more important, as it is usually integral to each size of helmet.
 
The "trick" is not in the size, but in the shape of the interior; round, semi oval, and oval.
Besides the size, you need to know the shape of your head.
The majority will fall into the semi oval class.
I take an XL (7 5/8 hat size).
In a round it's too tight, semi oval a tad snug, oval a tad loose.
Nolans tend to be round, Shoei are typically semi oval, HJC varies with model, Bell varies with model, Hawks are oval, etc.
Do not get a size larger or smaller to fit try to fit a square peg into a round hole just because you like a helmet. Get one with the proper interior.
If you do not know the interior design of the helmet you are buying, especially if online, try it out at a local shop OR watch a video review on the likes of Revzilla.
They always give the interior shape of the helmet during their reviews.

Bravo on the undertaking!

I agree with several of the previous comments. I sold riding gear for almost 8 years. People with an oblong shaped head are the hardest to fit.
Getting the right liner and size cheek pads helps but, you need to start with a helmet that is more oblong in shape. There aren't many of those out there and they are very expensive.

Check out the site referenced above. It is provided by the vendor MotorcycleGear.com. They have done what you are attempting with your data collection effort. The rub is that they charge $10 for a recommendation based upon the head measurements which you submit - and for an additional $10 they will sell you a paper tape and a caliper so you can measure your head.

Interesting website. I measured my head and it is an intermediate oval, not round oval. It is my jaw that is wide. Therefore, head measurements won't help with my jaw.

Yesterday, a salesperson at Revzilla went around measuring helmets the way I asked them to. They recommended the Bell Mag 9 Sena with 25mm cheek pads. I ordered it and it is out for delivery today. I will report on it later today. Revzilla goes that extra mile to please their customers.

I looked up human head anthropometry and found this to be the most common head measurements:

Men = 7.2 in (18.3 cm) x 5.2 in (13.1 cm) (ratio: 1:1.38

Women = 6.9 in (17.5 cm) x 4.3 in (12.5 cm) (ratio 1:1.60

Update. On 1/11/16 the people at Revzilla measured many helmets for me. They recommended the Bell Mag 9 Sena Helmet. I ordered it and got it today. I tried it wth the 45 mm cheek pads and couldn't get it over my ears. But, it fit fine with the 25 mm cheek pads.

See the new diagrams I added to: http://www.wb2lua.com/marticles.htm
