Topic tags/keywords: dining table dining

I’m in the early design stage (in my head) of a big dining table. My wife wants it 10-12 feet long, without extensions, and I’d rather avoid them as well since I’m going to be on a timeline. If I go 12 feet long, am I going to have not enough support in the middle and have it sag? I’m guessing a thicker top and rails could help, but how much? Or am I doomed to have to add some sort of a centre support?

Well, it depends on the thickness. For a 12’, 3” thick may not need any support although I would put one in the middle. And it depends on the wood as well. If it is going to be a thinner wood probably every 2’ would suffice. Just make sure your aprons are thick enough to support the top. You can contact me if you want and I’ll walk you through it.

Using a trestle instead of apron and leg will bring the support closer to the middle and help reduce sag. In a trestle you could run a center beam between the trestles with something like 2×6, this would further support the center and keep it from sagging. A thicker top will certainly help as well.

If it’s a trestle design, 24”-30” of overhang on each end will counteract any sag in the middle for a thickness of 1 1/2”.

Trestle is the way to go, with beams under the top running longways. That should be fine.

12 feet? Seriously 12 feet?

yes, i know that’s big. Maybe when I make a mock up of the size (fancy way of saying a big piece of cardboard) and put it in the room, she’ll downgrade the size a bit but its still going to be big and heavy. Originally I was against a trestle style base, but it looks like there’s lots of nice options out there in that style. Maybe I’ll have to re-think.

You can tuck a 6-8” vertical stiffener (I-beam) up under the top to support the span. You can have the ends cantilevered out by 2-3’ if they’re supported like this, which leaves 6-8’ in between. I’d only go with trestle if you like that farm look. You could go with a modified Rodel table if you wanted as long as the structure was there.
