My house was built in 1943. It is a wood frame house and the interior walls are lath and plaster. My goal is to find the studs so I can mount a TV bracket for a flat screen TV. I have read that the stud detectors can in some cases detect metal nails used to mount the lath prior to the plaster being applied. It may be removing the baseboard to look for the studs might be just as successful. My question is if the convention for studs being centered at 16 inches would have been in effect in 1943? I think the house was built by a European builder since the kitchen counters depths are a couple of inches less than the depths in more recently built homes.
16 inches on center.
Note that lathe and plaster has a number of advantages over more modern drywall, but studfinding is not among those. A standard stud finder you might buy or rent is likely to give confusing results. However a super powerful magnet, or a magnet based stud finder, will work just dandy. A row of small nails runs up and down each stud holding the lathe strips.
Removing the baseboards probably won't help at all. Often, but not always, one edge of an electrical outlet aligns with a stud. Framing can get funny near doorways or windows... the magnet is your friend.
