In nj and many older houses have 1x6 kind of base molding and 3/4 rounds. Even new houses generally have 3/4 rounds. Shoe moldings are usually found in cheaper houses. My house was built, I think, by a tradesman for himself. Renovated, I think, in 70s or early 80s, but remained diy style with 3.5" base without any 1/4-rounds. All trims dark stained without a clear finish and nailed with thin ringshank/small head nails flush with the surface. No popped nails and no dings on the trim.:smile:
Vertical moldings for doors and windows are usually 2.25" wide. So narrower than 4-5" wide bases don't look good against those trims. Wider the base, wider the finishing quarter rounds.
