The vertical height of the rafter tail.

normally we use a 2/6 for the fascia board on the rafter tail so it would be 5 1/2 inches

Everything depends on the slope of the roof and the design of the cornice or roof overhang. There is no standard size to my knowledge. If you want to understand the detail you should draw it to scale.

Every one is different. I usually use 1x8 fascia's and frieze boards. I like the roof to have a more substantial feel and I think this does it. The style of the house sometimes affects this as well.

I got a house with fascias made with 1/2 x 7 inch exterior plywood (actual thickness)). Most I see are 1X6 pine board 3/4 thick.
Is this a code violation in GA? Can it be a problem. Previous fascia was wasted due to no drip edge and roofing way past due an oil change.

Height of the vertical tail plus 2 inches. Use 2x lumber as oppose to 1x to prevent warping and waivy look.

Do you mean depth or thickness of the fascia member? There is no "standard". It all depends on the architectural style and design.

Chris, you do realize the question was asked 8 years ago don't you?

The width of the fascia should total the width of the house plus two overhangs.

I love old discussions.

Eight years ago...ugh! :-(

"The width of the fascia should total the width of the house plus two overhangs."

Also equal to the angle of the dangle.............

FYI. This was a very useful reference for me and came up #1 on a Google search Sept 2018...angle of the dangle comments are a waste of everyones time.

The thread is over 9 years old. It's much better to start a new thread, than tail end an old one, IMO!

The point of the comments is that there is no "standard" for the depth of a fascia. It all depends on the style of the architecture and the design intent of the architect.
