Is there a standard size for the inset in a new built wall, for the mount to be installed to hold up a flatscreen tv set?

I think it would depend on the size of the TV or the mount being installed. The mounts must go into studs to securely hold the TV.

Oh, okay... a logical dimension, not something that is just a "given".

I would make it a little larger than what is required. More or less "room to grow". I had made an entertainment center and sized the opening to fit the particular television which was popular in the time period. With the new age of digital flat screen televisions I cannot get one that will fit the opening and will have to down size in screen size when the older television "bites the dust".

36" by 60" should be big enough for any flat TV to be hung on a wall. That way you don't have to know what the actual size of the TV is. If you recess the TV into the wall you'll have to add more wall behind the main wall to cover the hole on the other side and to provide support for any needed brackets. Think about mounting the power outlet and antenna cable outlets into the rear wall.

Thanks to everyone who posted. We've built the niche in unit "E" and will follow through with all the others. Awesome kindness from all who considered my request.
