While 1” is not unheard of, since it is a handmade
piece I would recommend going to a little more
effort and making the mortises intersect. The
tenon ends can be mitered or notched out to
meet in the intersecting mortises.

If I were making that I would use a 3/8” x 2-1/2” tenon and go as deep as possible without interfering with the adjacent tenon from the other apron.

I agree with Loren. The traditional method is to make the mortises intersect.

I cheated a little and instead of mitering the tenons, I stuck one in full-length, then just chopped the other tenon to fit. It ended up a lap joint inside there. I really don’t think its hugely critical.

As concerns size, I’d go with 3/8” tenon. If you’re concerned with shoulder size, you could go down to 5/16”. If you are using a mortising machine, anyway. Most hand chisels are not made in 5/16”, so that’s not a good option if you’re chopping by hand. I know that the standard method is to have tenon about 1/3 of stock width, but I usually prefer them a little thicker.

The reality of the matter is, M&T joints are so strong, I think you’ll be okay no matter what method you choose, as long as you take your time and make a good, snug joint and glue well.

I can’t see that the shoulder width is of much significance. I use 5/16 tenons as I have a mortising machine with a 5/16” chisel, and thicker tenons are obviously stronger. Of course if you are doing them by hand, that’s a different matter.
