Helmets

To find out the helmet size you need, measure around your head, in centimetres, just above your eyebrows as in the diagram (it is easier and more accurate if you get someone else to measure your head) and then use the chart below for your helmet size.

If you are between sizes, go for the smaller size as the lining of the helmet will give a little over time.

Most helmets will follow the table below:

Helmet Sizes	Cms	Size
	51 - 52	XXS
	53 - 54	XS
	55 - 56	S
	57 - 58	M
	59 - 60	L
	61 - 62	XL
	63 - 64	XXL

However, AGV in some of their top spec helmets, have an MS size and an ML size. They do this to give a more accurate fitting in the most popular size bracket. MS is 57 CMs and ML is 58 CMs.

AGV Helmet Sizes	Cms	Size
	51 - 52	XXS
	53 - 54	XS
	55 - 56	S
	57	MS
	58	ML
	59 - 60	L
	61 - 62	XL
	63 - 64	XXL

Schuberth helmets also have a little different sizing system:

Schuberth Helmet Sizes	Cms	Size
	52-53	XS
	54-55	S
	56-57	M
	58-59	L
	60-61	XL
	62-63	2XL

Childrens helmets sizes are different again:

Childrens Helmet Sizes	Cms	Size
	50	S
	52	M
	54	L

Mens Gloves

To find out the glove size you need, measure across your palm, in centimetres, from the side where your thumb starts (but don't include your thumb) across to the side of your little finger, in a straight line across (not around) your palm and then use the chart, below, for your glove size.

If you are between sizes, go for the larger size.

When it comes to brands all brands either show the size in letters, for example M or L etc or in Cms. So if you follow the table below you won't go wrong.

As a rule Alpinestars gloves do tend to be on the snug size so you may sometimes need to go a size up.

Mens Glove Sizes	Cms	Size
	7	XS
	8	S
	9	M
	10	L
	11	XL
	12	XXL

Mens Boots

Motorcycle boots and shoes are measured exactly the same as your normal shoes would be.

However brands can vary slightly; Alpinestars and Sidi are slimmer in the foot (and calves) whereas TCX touring boots can be quite wide in the foot.

Men's Boot Sizes	European	UK

Alpinestars racing and touring boots have 'half' sizes and their euro size is compatible with these UK sizes:

Alpinestars Boot Sizes	European	UK
	41	7.5
	42	8
	43	9
	44	9.5
	45	10.5
	46	11.5
	47	12
	48	12.5

Leather Suits

Leather suits are measured in inches around the chest, just under the armpits. The waist measurements are, usually, around 8-10 inches below the chest size for example a size 46 chest suit will have a waist of 36-38 inches.

Brands such as BKS, Frank Thomas and RST all follow UK inch sizes.

Alpinestars, iXS, Dainese and other European brands have European sizes. European sizes are exactly 10 above UK inches so if you’re a 46 inch chest then you will need a size 56 in Alpinestars.

Remember, we have translated all the sizes on our website to UK sizes to make this easier for you – but if you’re looking in store then a size 56 is what you will need.

Alpinestars, Dainese, iXS, European Leather Suit Sizes	European	UK
	48	38
	50	40
	52	42
	54	44
	56	46
	58	48
	60	50

Leather Jackets

Leather jackets are exactly the same as leather suits – they are measured around the chest (just under the armpits) and the brands are exactly the same.

So, brands such as BKS, Frank Thomas and RST all follow the UK inch sizings.

Alpinestars, iXS, Dainese and other European brands are again in European sizes. European sizes are exactly 10 above UK inches so if you’re a 46 inch chest then you will need a size 56 in Dainese. Again, we have translated all the sizes on our website to UK sizes to make this easier for you – but if you’re looking in store then a size 56 is what you will need.

Leather Jeans

Jeans and trousers are measured, as you would expect in inches, around the waist.

Frank Thomas, RST and BKS it is simply your waist in inches.

However European brands refer to different UK sizes. For example, a European 54 in Alpinestars is a size 36 in inches. (you just subtract 18 to find the UK inches). But in iXS a size 48 is a size 38 (subtract 20) See the tables below for brand specific sizings.

Textile Jackets

Textile jackets are measured around the chest (just under the armpits) and the majority are measured in M, L , XL etc.

Again, some brands can be a bit smaller than others (Alpinestars) and always remember that if you plan to wear extra layers underneath this will change your sizing.

Textile Jacket Sizes	UK (Inches)	Size

	46	XL

	50	3XL
	52	4XL
	54	5XL
	56	6XL

Textile Jeans

Jeans and trousers are measured, as you would expect in inches, around the waist and then converted into M, L , XL etc. Please see the table below:

iXS textile trousers specifically have an extra letter on the front of their long and short trousers. "L" for Long (obviously) and a more baffling "K" for the short leg. Again, this is translated online but in store this is what those letters mean.

Ladies Motorcycle Clothing Sizes

Ladies clothing is a little harder to navigate than mens.

There is a general sizing guide and lots of brands tend to size ladies items in ladies UK sizing such as 10, 12, 14 etc. which would make it seem that it is easier, however, a lot of these brands are very small in sizing so you may find you're a size bigger (maybe even two) in this clothing.

Ladies leathers are all in UK sizing so this makes life a little easier – but just remember that Alpinestars and Dainese are small sized; as is iXS, but we translate European sizings to UK sizings and compensate for this (as you can see below iXS are a little different to normal euro and UK ladies sizes).

IXS Ladies Leather Sizes	European	UK
	38	8
	40	10
	42	12
	44	14
	46	16

In textiles here is a guide for ladies sizing. This is very apt for BKS and Frank Thomas (bear in mind that European brands can be smaller).

iXS ladies textile clothing has the letter "D" in front of all the sizes, as a swiss company they use "damen" (German for ladies) and Frank Thomas sometimes has the letter "L" preceding the size to distinguish the ladies clothing ranges.

Ladies Textile Sizes	European	UK
	XS	8
	S	10
	M	12
	L	14
	XL	16

Ladies Gloves

As with mens, hold your hand with the palm facing up and measure, in centimetres, in a straight line across your palm from the side where your thumb starts (but don't include your thumb) to the side of your little finger.

When it comes to brands all brands either show the size in letters, for example M or L etc or in Cms. So if you follow the table below you won't go wrong.

If you are between sizes, go for the larger size.

As a rule Alpinestars gloves do tend to be on the snug size so you may sometimes need to go a size up.

Ladies Glove Sizes	Cms	Size
	5	XS
	6	S
	7	M
	8	L
	9	XL

Ladies Boots

Motorcycle boots and shoes are measured exactly the same as your normal shoes would be.

However, this is the general womens size guide, the motorcycle world can sometimes be a bit behind on their female sizing and boots are no exception. Sometimes boots can be labelled up as womens but feature men's sizings. We try to compensate for this with our translations online but in store watch out for it.

Ladies Boot Sizes	European	UK
	35	2.5
	36	3.5
	37	4
	38	5
	39	6
	40	7
	41	8

Kids Sizes

Kids clothing is far too varied to put in to tables. Every single item of clothing we sell (even in the same brand) is different to the next. iXS measure their children's clothing in the height of the child in centimetres, whilst other brands tend to age bracket their clothing and others just assign a S, M, L etc.

We try to translate as well as we can online but trying the clothing on is key here. If you do order online and it isn't right you can exchange or get a refund no problem at all.

The same applies to childrens helmets. Each brand is different and every helmet varies too. Online this is explained and translated in to Cms.

See the helmet sizing guide above to see how to measure your child's head. Different brands give different sizes for kids - if you're unsure what size you order online for kids helmets then either give us a call or e-mail us to check that you're getting the right size.
