yes, but I am talking about standard plywood, that comes in 4 x 8 sheets,
typically sold in the big box stores.....

1/4" for the BORG stores

They also have 1/8" birch ply along with the aforementioned "door skins"
If your original post revealed WHY/WHAT size you were looking for, it would
have cut the replies on this thread by 80%

If you question really was: What size ply does HD/Lowes sell ? A couple of
phone calls would have answered your question.
