goggles dont come in sizes but in styles. Its wathever feel more conmfortable to you, the adjustment is done thru the strap. If you are talking about prescription it is usually what your glasses prescription is if its different on both eyes go with the lowest prescription. otherwise you will feel disoriented.

They are adult size with different nose pieces to make a more custom size. If you mean correction strength ask your eye doctor. My son is nearsighted, he needs a negative correction I got him -2.0

Great question! We do not record the glasses size because we sell them on somewhat of a "one size fits most" designation. I can tell you that my glasses sizing is 53x17x140 and they fit me just fine. I hope this helps answer your question.

Size is for the flippers. I have a small head and the goggles are perfect. They do have adjustable strap though.

There is a measurement scale on the website it will tell you what size you need

I am not sure, but I would hesitate to buy something untried when one has either a smaller or a larger fit than is standard for such things. Obviously, one can tighten the strap. I have a big head and wide face and they fit me and my eyeglasses well. So with that perspective, if they offer it in a small size, I would go for something that offers sizing. Hope that helps.

You most likely want to get them junior size goggles. We think these would most likely be too big for them.

Inside diameter of extender is about 1.5". Measure the diameter of the tube with the eyepiece set screws. If it is about 1.5" you are all set. The extender has to slide over your eyepiece and clamp in the same area where your eyepiece set screws are.

not that I can tell. I've been swimming for about 8 years (gone through maybe 10-12 pairs of goggles) and I found that these fit great for my face :-)

Style of glasses and size - I can't tell you exactly, but visit a store where there is a display, hold your glasses against the display and you will find the recommended size/style for your prescription glasses.

If you look at the size chart and you see that your objective and ocular is close to a size. Some people will go to the size smaller or size larger. If you go smaller you can heat the rubber up in water and slide it on for a tight fit. If you go a size larger then you put a strip or two tape around it for a good fit as well for your ocular with a 1.69 you would either go size 18 or 19 size 18 is 1.67 and 19 is 1.70.

Didn't measure it. Then again, what's a "regular head" size anyway :)? They fit my 7-yr old son, now 9. My then 10-yr old son preferred the slim adult goggles. We've tried many goggles. For 9 & under, I recommend Sporti Antifog Cabo Jr. (see swimoutlet-com). They are slim and better fit for smaller faces, come with a case, and forever fogless, not to mention cheap and practically disposable for those kids that keep losing their goggles (mine don't - they learned not to after hearing it from me).

Thank you. I have '80s size glasses. If goggles fit, then these should fit too.

I purchased these goggles for my 10-year old daughter and they fit well. She loves them!(FYI, I measured my daughter's head where the goggles would be placed and got 22")

look for the size of a particular glass in the product description (on Amazon of course). you will see numbers like this 55-18-14555(mm) will represent the lens width18(mm) will represent the bridge width145(mm) will represent the overall length of the armthese numbers change with the models - GR003, 004, and 001, etc. I took a pair of sunglasses that fit me well on the brigde of my nose and the arms length and measured them. Prescription glasses may have the measurements on the arms already. Google how to properly measure for glass frames and then find your match of Gamma Ray. The Gr001-C1 matched mine, although I think I got the bridge a mm larger just in case. look for the size of a particular glass in the product description (on Amazon of course). you will see numbers like this 55-18-14555(mm) will represent the lens width18(mm) will represent the bridge width145(mm) will represent the overall length of the armthese numbers change with the models - GR003, 004, and 001, etc. I took a pair of sunglasses that fit me well on the brigde of my nose and the arms length and measured them.
