18" wide formica countertop on half wall?


I am worried about weight. I was going to build a 2x4 studded wall to save a little space but i am worried about the weight of the countertop. Is there a formula or a way to go about figuring this so i mess this up?

What I've done before on any half wall that may be exposed to stress, is to go thru the floor with a stud every 4' and tie it in to a joist (assuming you have access to the underside of the joists)

Along with Mrgin said,
If you want to stiffen up a half wall, sheet at least one side with 1/2" plywood, then install your finish sheathing, drywall, paneling, etc. Your formica top isn't all that heavy, but it will require some additional support in the way of knee bracing or the like to keep it from sagging.

The overhang needs to be supported. A 4 1/2" wide wall will not support this size counter by itself. You will need shelf brackets or corbels.

I would mount a piece of plywood to the top of the wall and use it to screw the countertop deck for fastening.
Also, a knee brace on the longer overhang side.
