2x3's have been around a long time.... they don't have the structural
strength of a 2x4, and require 12" c/c spacing when used in bearing
wall partitions.... that means 25% more studs than if you used 2x4s
(plus the additional labor cost of setting 25% more studs!), so much
for cost savings! In my area, for the past 25-years or more, it has
been typical to use 2x6 studs for exterior walls because of the
additional insulation space available.

I noticed that Home Depot is stocking 2x3 studs these days. I have used
them for a small garden shed and they are much easier/lighter to handle and
still give the strength for most places. I'm just wondering why these
haven't been produced longer? The price is about 25-35% less than 2x4's.
