When Viba Hardware started offering doors 3 years ago, we had a very standard size offering. That ended pretty quickly.
Our current average size of door is 84X40 inches, but that is the average only. We regularly do massive doors for clients looking to solve specific problems. I have posted a couple of pictures below of recent client doors we have done. The first is for a 6 foot by 80 inch door that will be used to cover over a large opening between rooms in a basement. The client had a 5' 5" opening with lots of wall space on one side, but none on the other,and didn't know what could be done. When they contacted me, I immediately recommended a larger door sliding in the one direction to give them the privacy they wanted.
The main point of this post is DON'T THINK THAT A DOOR THAT BIG CAN'T BE MADE! We do doors up to 96 inches high and 76 inches wide on a regular basis, and pricing for those doors is always available on our online store.
Until next time remember- Do-it-yourself or Do Not. There is no Try-it-Yourself.
