How should I choose a skateboard or what should I get?

I am 16 yrs old and I am about 5ft 10in and I wear a size 12 shoe in boys or mens or however they measure it. The reason why I included all that stuff is because I'm looking at boards and some are 9 inches wide and some are 7.2 inches wide. I've never really had a skateboard before and I want get in to it. I can kinda do some tricks...... I guess I can barely or have never done an Ollie but I'm working on it, and I'm looking todo intermediate tricks like kick flips and 360's and grinds and small to medium jumps, but not any big jumps......... So what board should I get? I want either a plan b, baker, or darkstar board.....or something red,black, and white
