Talk to your installer prior to ordering
Walls are never perfect and giving them the dimensions is not enough.  They give you exactly what you said the dimensions are and not and inch more.  In my case, one sheet was a little short.  I think they should give you a little more just in case or ATT least they should advise you to order more.  I’m unhappy with their lack of help during the ordering process.
