Hi tracyritz, it's more of a personal preference, but I fine wider planks make a space cleaner. I would not bevel the hardwood for the same 'clean' look reason.

Tracy I would agree with Dytecture. A wider plank definitely gives a cleaner look. Most installers agree that a 5" still only needs just glue or a nail to install and not both. I attached a couple pics of a long length 5" quarter sawn white oak we made for a client in Charleston.
