I've seen a golfer show how to measure a golf club by useing your body.If the golf club hndle touches under your armpit to the ground striaght up and down then its the right size.
My point is I'm sure there's many different ways to measure a bike to your body size.
I don't mean a motorized bike either.
Any Ideas?

For a really detailed (and fully interactive) method to determine what size bike to get, check out:

And use their "fit system" link. It seems like its a bit too in-depth, but it will help you not only to pick out the right frame size, but also help you to adjust the bike approximately (of course, you'll want to find what's comfortable).
From my experience, it's pretty accurate. Still, you can play around with the sizing a little. Although it recommended a 58 or 59 cm road bike for me, I ride a 60 cm.

Frame size (road bike): For this method, you will need a record album, or large, thin book; a measuring tape; a friend to help you. First in bare feet and wearing cycling shorts, stand with your back against a wall. Place your feet about 6 inches apart. Put the record album or book between your legs with one side flush against the wall and the other side sticking out in front of you. The top edge should be parallel to the floor. Raise the record album (or book) until the pressure you feel against your crotch is equal to the pressure you feel from a saddle when you're pedaling easily. Hold it there and have a friend use a measuring tape to measure from the top of the horizontal edge of the record album to the floor. Record this crotch-to-floor distance precisely in centimeters. Then multiply this measurement by 0.65. For exemple, if your crotch-to-floor is 87cm, then multiply 87 by 0.65 to get 56.5 cm. This means you should ride a frame that measures between 56 and 57 cm. Frames are measured along the seat tube from the center of the bottom bracket to the top of the top tube. However, many modern-day frames don't have the traditional diamond shape with a top tube parallel to the ground ( so it can be hard to find the center-to-top measurement on newer frames.) Most manufacturers give a "virtual seat tube height" measurement for bikes that are designed with angled top tubes. This makes it easy to choose the correct frame size without awkward measuring.

The general rule of thumb I learned while bike shopping was while being on the seat of the bike you should be able to have your feet flat on the ground. If your feet touch TOO easily to the ground, and you have to in fact bend your knees, then you either have to move the seat up, or if the seat doesn't go up further, then move up to the next biggest bike.

A cycle retailer once me to sit on the saddle and you should be able to touch the ground, both sides, with your toes.
