I am trying to make Baseball caps with a logo for a company and they have a pretty lengthy name wondering on the best layout.? Thanks guys!

The dimensions are going to be different for different hats. I mean, you have to take into account the size of the head, and other such things. It's all relative.

Try just using the initials - Like NY for new york

New Era makes hats for major leauge baseball - viewing their catalog should give you some ideas:
