- go with the 50 cm
-if the bike has a slopping toptube then 51 is the top limit
-52-54cm i believe would be to large a size, as your saddle would be low, the way that the market and the types of bikes sold is going, is that people usually buy a bike which is rather small for them so that they can compensate it with seatpost height.

1st answer mentioned your inseam - that's a little better than total height. Because of other frame geometry a size number isn't exact either. But at your height, 52 and 54 are too big for sure. I ride a 52 Cannondale it's a perfect fit and I'm 5' 8". If you have long legs a 50cm may work but it would be close to being too large too. A bike fit means so much I can't emphasize it enough. What good is a bike that's too big so that you can barely reach the break levers or your back and butt hurt when you ride?
If your buying local you get to check the bike out in person, that's fine. If on-line you don't have that option. If you can't stand flat footed over the bike it's too big. If your streched out too far you can always get a shorter stem (unless it has a short one already) Please don't buy a bike too big for you because you like the looks or specs on it.

My 13 year old son is 5'6" and he was fitted to a 53 cm frame. The appropriate size for him was 52 cm though. The frame ran a little big for him and he has pretty long legs. He now rides a 53 because he will grow into it within a year at the rate he's growing. I would guess a 50 or 52 cm frame would be your size. Check each frame that you see in a particular size. Some frames run bigger than others of the same size. You might see a 50 cm that fits perfectly and the frame will actually be a 51 cm. You need to go to a bike shopregardless. If you get the wrong size used, you may have a nice rig that isn't very comfortable to ride. Not a good way to invest your hard earned cash.

No a 54 will be too big for you. At 5'3" you are looking at somewhere between a 49 and 51 in terms of size. Bear in mind this is according to averages and everyone is a little different. But after working in a proshop for years, you get pretty good at sizing people. I'd start at a 54 for a rider that was about 5'8" in height.

Well it depends on your in seam measurement on proper bike fitting measurements.
Measure your in seam by standing on a wall with two feet placed 5 cm apart. Insert a book up you crotch and leave it there. Then measure the top of the book (touching your crotch) to the ground and that is you inseam measurement.
For roadbikes, multiply your inseam measurement by 0.67 and convert that to cm. Then this is roughly your frame size.
I think you can ride a bike +-3cm from your exact frame size but you will sacrifice power transfer and/or comfort.
Riding with a larger frame causes the bike aesthetically to look odd because the seatpost is almost fully choked by the seat tube.
On most cases, people only judge if they fit the bike by standing with the bike top tube between your legs ang making sure there is at least 1inch distance from the toptube to the crotch. ( I do not recommend this)

I'm 5'8" and ride a 54, so i doubt that you would be riding the same size.
