What size of molding to use?
When looking at our crown molding you will notice a measurement called "Breadth". This is the size of the facing of the molding and can be used to determine how large you want the molding to appear on your ceiling. Here are some general guidelines that are all based on my opinion (so feel free to choose your own size even if it is outside my figures):
Small-Medium Room
8' Ceiling: 2" - 5" Breadth
10' Ceiling: 4" - 8" Breadth
12' Ceiling: 6" - 10" Breadth
14+' Ceiling: 8" or wider Breadth
Large Room
8' Ceiling: 4" - 7" Breadth
10' Ceiling: 5" - 10" Breadth
12' Ceiling: 7" - 11" Breadth
14+' Ceiling: 9" or wider Breadth

Inside Corner-Left Piece
When you are at your miter saw have the long part of the molding extend out to the left. Move the saw angle to your right to the 45° mark for a 90° corner or your calculated angle for an angled corner. Make sure the top of the molding is on the saw deck and the bottom is facing you. Hold the molding at the correct angle and make your cut.

Two Methods to cut crown molding
http://voices.yahoo.com/cutting-installing-crown-molding-easy-way-225878.html
There are two methods of cutting crown molding to fit them. One is to position the molding on the miter saw's fence and table at the same angle it will be when it's installed against the wall and ceiling. In that case, the conventional 45-degree miters are the correct cuts. And that's the way most instructions tell you to do it. However, that method can present a major problem. It may not work. If your miter saw doesn't have a high enough fence to rest the molding against, especially when wide molding is used, you'd be out of luck. Plus, if you don't position the piece perfectly, the cut will be wrong. Fortunately, there's another way.
It's much easier to cut the molding while it's laying flat on the saw's table and against the fence. The height of the fence and width of the molding aren't an issue. But in order to do this, the miter will have to be set at an angle other than 45 degrees. The correct angle to set the miter is 31.6 degrees.
There's another angle involved, and that is the bevel - the angle to set the blade. That is 33.9 degrees. Fortunately, all power miter saws have the angles clearly marked, and many of them already have these correct crown molding angles highlighted, so it's a simple matter of setting them. The machine may even have a miter locking stop at 31.6, which makes it even easier.
Remember, these angles will only work for cuts made when the molding is placed flat on the saw's table.
There are four basic miter cuts for crown molding. They are inside left (IL), inside right (IR), outside left, (OL), and outside right (OR). For all four of these cuts, the miter is set at 31.6 degrees, and the bevel is set at 33.9 degrees. The only changes you will make to the saw will be setting the miter left or right.
Following are the procedures for the four basic cuts. Remember, the bevel is always set at 33.9 degrees, and the finished side of the molding is always facing up. Refer to photos.
IL (inside left)
Miter setting 31.6 degrees RIGHT. Top of molding is placed against saw's fence. The left piece will be the finished piece after the cut.
IR (inside right)
Miter setting 31.6 degrees LEFT. Bottom of molding is placed against saw's fence. The left piece will be the finished piece after the cut.
OL (outside left)
Miter setting 31.6 degrees LEFT. Bottom of molding is placed against saw's fence. The right piece will be the finished piece after the cut.
OR (outside right)
Miter setting 31.6 degrees RIGHT. Top of molding is placed against saw's fence. The right piece will be the finished piece after the cut.
