I’ve just finished framing a 2×4 North American style house here in Japan. I’m starting the drywall and finish work next week after inspection.
The doors are from Sauder, colonial-style hollow-core paint grade. I’ve asked the company contracting me to bring the hinges so I can pre-hang all of the doors. They brought one set and the hinges were 4”, which I have always thought to be for exterior doors. The hinges are way too wide for a 36mm approx 1 3/8” thick door….
I phoned their regular door specialist, and he told me they use those 4” hinges because they have had lots of problems with the doors warping, and the larger hinges helped prevent that.
I don’t really go for his solution, I’ve always used 3 1/2” hinges on interior doors. Does anybody have any input on the subject??
Input would be appreciated…
Thanks,
Scott S

Sounds like they're feeding you a line.
That explanation makes no sense.
There's nothing wrong with using 4" hinges inside, I've done it many times on heavier doors, on the big over sized solid interior doors I've used 5 & 6" hinges. From what you say though, these are hollow core doors and 31/2" has always been the norm for those.
As far as the warping goes, it's not the size of the hinge so much as it is the number of hinges used. If you think there will be any chance of warping , it's best to use three, sometimes even four sets of hinges per door, depending of course on the size of the door.
4" may be their solution, but like you I question its effectiveness.
My experience is that the company makes really cheap (Walmart) type junk.....don't suppose their doors would be any different.
Can't see the hinge stopping a door from warping..........
I've never liked hollow-core doors myself either.... but I don't get to choose the products used, unfortunately..
Adding hinges sounds like it may give the door extra support anyway, I just didn't see the use in installing 4" hinges on the lightest doors on the market...
