Making a small table. Legs will be 1.5” x 1.5” where the 3” aprons attach. I am guessing that a tenon 1/2” W x 5/8” D x 3” H will suffice. If the tenons are 3/4” D they will bump into each other, barely. Is there any “rule book” on how big to make M&T’s? Thanks. john

I’m sure 5/8” deep tenons will suffice, but if you went with 3/4” you could miter the tenons, or off-set like I did on a recent Prie Dieu build …
 

 
May I assume you will be using drawbore pins? Also, if your apron is 3” wide you might consider making you tenon 2-1/4” or 2-1/2” high.

j, there is no rule book, but there are rules of thumb. Typically, the tenon is about 1/3 the thickness of the aprons. Also, you need to have a shoulder on all all 4 sides for strength. I usually leave about 1/2” at the tops and bottoms. It is okay to bevel the ends of the tenons so they almost touch. Another option is to locate the tenons off center, say 1/8” from the outside edge which will buy you a bit more tenon length. HTH

thanks for the replies! i had not considered the drawbore pins, but i do recall reading about them and see their use. thanks for reminding me. i assume they are 1/4” dowels or so??? i was planning on shoulders on 3 sides, since the aprons are at the top of the legs, but if 4 shoulders are better i will do that. a guy’s gotta learn how sooner or later….john

The pins I use are just shy of 3/16”. Shoulders on three sides would be fine … you might even considers a haunched tenon.
