An 8 x 4 propeller is eight (8) feet in diameter and four (4) feet in pitch. The pitch distance is the theoretical distance the propeller would be pushed through the air during each revolution. Obviously, this refers to fixed-pitch propellers; a variable pitch propeller has a different pitch for each given setting.
This assumes, of course, that you are talking about real airplanes, rather than model airplanes, as one answerer above was apparently doing.
And as for the other answerer, it continues to escape me why people want to give bogus answers on subjects they know nothing about. Crazy!

Regardless of whether it is a model or "real" aircraft, the propeller size is listed in inches. Yours is evidently a model propeller, because the diameter of the arc is 8 inches. The second number, 4, is how many inches at 100% efficiency, the airplane would move forward with each revolution.
A fullsize aircraft would be a 96 x 48.

it refers to the size of the propeller, not the number of blades. i have included a link for you to check out. an 8 x 4 would be an 8 inch propeller with a 4 inch pitch http://www.hobbypeople.net/gallery/608240.asp

I am guessing.I think its 4 propellers with 8 blades.
