What do measurements mean when it comes to bicycles? Some are 16 inch, some are 19 inch, etc.?

Bike frame measurements are taken from the center of the crankset to the top of the seat tube (C-T) or to the center of the seat tube (C-C).  Which size you need depends on the particular frame geometry (straight or sloping top tube), your leg length, and whether the bike is for road or mountain.  Also to be considered is the top tube length.  This is important as different people with the same leg length may have different torso lengths.

I think 16 is around 35in. in the waist and 42 in the hips. Lands End has size charts in inches on their internet site.\n\nwww.landsend.com

I've seen a 450 cc, and I thought that was big, but I recently came across a 500 cc as well!  I haven't seen any bigger than that.  I tried my friend's 450 cc, but I don't like them.

Whatever size you feel comfortable on. You shouldn't buy a bike based only on your height. Some people like bikes that are a little lower, some a little higher. Just try a few out a see what you like.

Actually, if you are talking about young peoples bikes (16", 20", 24" wheels) the differece is typically only color and cosmetic features.\n\nAs one gets past this stage, to "adult" bikes, you'll find yourself in a design transition that started in the early 1990s...\n\nIt used to be that womens bikes had a "drop tube" frame, supposedly to allow easier mounting. This drop tube style was actually a throwback to the 1800s when women wore dresses and they could not lift their leg over a top tube without "showing a little". Unfortunately, this "parallel tube" design proved to be much weaker than the typical "diamond" mens frame and so womens bikes had to be built heavier.\n\nAround 1990, some manufacturers realized that very few women wore dresses when they rode, so they started a redesign based on anthropometrics, or the standard measurements of a human body. They discovered that women tended to have longer legs and shorter torsos than the same height man, so they decided to start with a diamond frame and readjust the geometry to better fit a woman. \n\nThen, they introduced the diamond womens frame. Stronger, lighter, and much more stable.\n\nThe bottom line is that men and women both have a lot to lose "down there", so the design never had anything to do with genetics. It was, of all things, modesty.\n\nSo, as we move on this path, you'll discover that only the cheapest bike brands (plus some traditional, comfort-oriented brand name bikes) will have a drop tube frame. The diamond frame and it's variants are the future of womens frame design.

You can get the proper answer about a bike for your daughter by going to a bike store.  The people working there will be able to  help you a lot.

well, since your other question dealt with threaded vs. threadless steerers, I'll assume you're not talking about new technology.\n\nA lot of the time, bike types are referred to by the diameter of the wheels, 20" bike is a standard BMX type, for instance.  26" used to be a fairly popular size for '10 speed' road bikes.\n\nA 66 cm bicycle frame is HUGE, most manufacturers standard sizes stop at around 60-62cm.\n\nThe way to find out what size your frame is would be to take a tape measure and find the distance between the middle of the crank axle and the middle of the seat tube/top tube junction on a standard diamond farme.  Basically, you're measuring the length of the seat tube.  For more information, refer to the website below.

Well being 5'2 you need to be on a shorter frame not neccisarily wheel size.  You will grow into it.  Plus with it being your starter bike so to speak it is going to take a good bit of abuse so talk to your local bike shop and they can fit you up with somthing good.  There arnt to many bikes in that price range that are really decent and most bikes in that range tend to be about the same quality so also look into a DK even.  Also invest in a helmet!

if you are reading sheet music it has to do with a time signature. I the top number indicates how many beats are in each measure while the bottom means what type of note gets the beat. If you were refering to the size of a violin the sizes are 1/16 1/4 1/2 3/4 and4/4. A full size violin is 4/4 so a 1/2 violin is half the size of a full size.

For a road bike, look at something in the range of 56cm to 58cm.  For a mtn bike, look at something in the range of 16.5 in to 18 in.

At least 13 inches...

The scale would tell you that.  For example a hot wheels car is 1:64 so 1 inch on the hot wheel is 64 inches on the real car.

To some degree I'd agree with the previous answer, but I think with the sloping top tube frames common today, your real criteria should be the top tube length.  Yes, it's true you want some clearance over the top tube, but I think you should look more for the appropriate reach.  Keep in mind you can change stems, but that affects the handling to some degree.\n\nI totally agree with the previous answer that you should go into your local bike shop.  You could be long legged, or have a long torso, and have long arms.  Good bike shops do customized fittings, measuring almost every part of your body.  It also depends a lot on what kind of riding you want to do.  Leisurely, comfortable, or racing?  Racers tend to want to be more stretched out, more aerodynamic, and it's actually easier on your butt because you have more weight on the handlebars.  But it could be harder on your back, neck.   Giant and some other companies now have two different road bike geometries to meet these different needs - OCR (more upright), and TCR (more stretched out), for example. \n\nIt also depends A LOT on the company and how they measure.  For example, I'm almost 5'11" and I ride a 58 cannondale, but a 56 in other brands.  They all measure them differently!  Confusing I know, but a good shop can help you.  You can ask if they have a "fit kit" or the serotta fit system.\n\nGood luck!

There are more variables than you might believe involved with a good fit, not just height.\n\nCall your local bike shops and ask if they offer a professional fitting service.  Expect to pay $15 and up if you don't buy a bike from them.  Could save you many bucks trying to correct a mistake.\n\nHere is what the shop i frequent uses:\n\nOur technicians use the FitKit, the Salsa Size-O-Matic Stem system, and the Cyclemetrics FitStik fitting tools as well as our years of experience addressing a variety of cyclists’ needs and fit requirements.
