I'm looking to design a custom ranch home that will be a similar layout to an original floor plan from the 1950's. The drawing shows the interior wall thickness to be 2-5/8", which is confusing to me. Do you know what framing studs would have been used if the thickness is 2-5/8"?
sometimes they would turn the studs sideways to get extra space. so 1 1/2" + (2×5/8) = 2 3/4" +/-. usually near a vent shaft from below or plumbing riser.
Nominal 2 x 4's used to be surfaced to 1 5/8" x 3 5/8". Sounds like the wall might have been built of flat studs plus 1/2" drywall on each side, adding up to 2 5/8". Probably not a particularly good detail to emulate.
I second the answers above. Don't emulate this detail. You wouldn't be able to run any electrical (or plumbing if needed) in the wall. I'd stick with a standard framed wall.
There are multi family contractors that use 1/2" as well, basically at any non-rated wall. I'm working on a project in KC right now that has 1/2" in the units, and 5/8" on corridor, devising, and exterior walls.
but i've seen 3/4" used in lieu of masonry partitions when separating uses. it's a special order item though; takes a couple of weeks to get it on site.

jeiffert - interested to know which decades for that resurfacing on 2x4's
Pretty sure the conversion from 1 5/8" to 1 1/2" happened in the early 60's. Not so sure how long the 1 5/8" standard lasted.
many thanks. i always spec 5/8" but do most single family contractors use 1/2"?
1/2" is far more common in single family construction.
in nyc now on high rise you have yo use the high impact resistant gwb now. is it like this elsewhere?
shaft walls
i always spec 5/8".

A habit that separates the best from the rest.
they make light weight gyp bd now. used to be 5/8 type x cost the same, so you might as well use it everywhere. but, light weight changed it all.
