Hi all,

I am making an apron-less dining table out of walnut about 1” thick table top that is 78” x 34” long/wide. There will be three cross table cleats (with slots for movement) underneath to give it added rigidity as well as two sets of metal supports that go from the bottoms of each leg set up towards the middle of the table to stop any sag. Very similar design to the following table except the 2 outer cleats will double as the way I attach the table top to the X Legs:

My question is how thick and wide do I need to make the legs themselves? Is something like 1 3/8” thick and 3” wide for each piece of the ‘X’ solid enough to provide both a good half lap joint and be structurally sound? Am worried if I make the legs to wide and too thick it will look out of proportion to the relatively thin table top since there is no real apron (though the outer cleats will provide an apron of sorts on the two ends of the table I guess).

This is my first dining table so thanks for the help!

1 3/8” x 3” will be fine. Lots of outdoor picnic tables are built this way with standard 2×4’s, which are typically knotty softwood and not much different from your dimensions. Go for it!

Being tied together at top and bottom means your essentially reducing the load on the legs to just tension by eliminating the bending load that could occur if the legs were allowed to try to “splay out”. So yes, I would say that 1-3/8 X 3 is plenty beefy.
