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

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.

You can measure the dimension of screen from inside the border. Actual screen size. Or You can find actual size of your screen from user manual of your devise or manufacturer's website or you can search on internet with model number and you will get the actual screen size.This perfectly fitted with my Garmin nuvi 50LM.

Like you, I don't know what the difference is. I can tell you that my measurement is 21 1/4 " circumference where the goggles fit and these goggles fit just fine. I have a small head these goggles fit me just fine. I hope this helps..

Mine were the regular size and I have an average to small face and the fit was great-my problem was the fogging after the first swim, sent back...Wish they would have performed better-the fit was great.

I got size information from the product website. It tells you how to measure your dog's head to determine what size to buy. Works well for us.

This is the Bulter Creek Size Chart for the flip-up covers.. http://www.blackbearsportinggoods.com/v/vspfiles/files/reference/butler_creek_scope_ref.pdf Find your brand & model. This chart gives you the exact size(s) for the eyepiece & objective.. If your scope is not on the chart I would recommend using the manufacturer's website to cross reference their measurements for the scope with your own. Chances are if you're measuring 1.98", 1.96 will be your size. You would want the more snug fit to keep rain & other elements out. Too big & it will slip & rotate off the objective. Sorry for the long answer.. Good luck!

I use the goggles in a indoor chlorinated swimming pool only. I believe I have normal size face and the fit is great.

They fit nicely over my prescription eyeglasses. Mine are about 55 mm, but they cover them nicely without pushing them into my face. The only issue I've found with the goggles is that they are just a little too big to comfortably fit with my half-helmet. I like to have my helmet pushed down fairly low, so if I'm wearing the goggles I usually go helmetless or with the smaller skidlid.

They give a measurement on the size they fit, look at the ad and measure your grips, there are 2 different sizes
