I second the 16 footer. The reason being is that most custom homes that have great rooms have ceilings at least 20' high. With a 14 footer you'd almost have to be on the top step to attach the canopy of a chandlier, or whatever. And with a tool belt on standing on that top step thatr high up is dangerous and could be career threatening if you were to God forbid fall. This is an interesting subject because this week I either have to buy an 8 or a 10 footer A-Frame myself.
