Architectural trim and mouldings vary with the architectural style of the house. Colonials differ from contemporaries, etc. Generally speaking, base trim is often the largest, with cove moulding (where it may occur) often the second largest trim piece. Window and door trim (head, jamb, sill and stool) are generally somewhat smaller than either base or cove. Of course, there are all sorts of options and choices, so this is only a starting point. I would not make window and door trim equal in any sort of historic period house. I don't understand your last paragraph about window "inside" trim. Are you saying that you have no trim on your existing windows? Hope this helps. Good luck with your project.

Yes, she is replacing the entryway trim because it got damaged when they installed her IKEA cabinets this summer. IKEA cabs gives her a more modern look which is why I said it was transitional, so her place isn't really traditional. I always thought painted everything looked more traditional? Anyway, I saw her place but don't have a pic, and what I thought was that next to all these stained cabinets white paint might look off? Or not?

Option 1 is fine. Don't see what the big deal is. In older houses, it was very common to have different styles (grades) of trim in functionally distinct rooms. Here are the two side of the dining room/kitchen doorway in my house: Dining room has fancy dentil molding, which is what's also in the foyer and living room. Then you go through the doorway into the kitchen, and this is on the other side: Super basic trim plus rosettes. Victorian equivalent of standard issue trim. This style is also upstairs (but not in the bathroom). They only went all out in the "public" rooms and then transitioned to the simple stuff for the kitchen because it's a kitchen. If the standard issue trim doesn't work in the bathroom (a separate and functionally distinct room), then get the trim that works.

Those modern farmhouses have several commonalities that I see at first glance. Examples being (some of which were noted): white exterior, white eaves, black (metal) roofs, black window sashes with minimal white trim, Design elements, not an architectural style. large windows, Ok could be architectural if it had a better description of the type of windows and how they relate to the rest of the house. lots of windows, front porch entry, Design elements, not an architectural style. roof gables with a strong pitch and relatively minimal adornment, Now this describes an architectural element that helps define a type of house. and when there are adornments they’re natural (ie cedar), vertical or horizontal siding (or a mix), and usually a board and batten element. Again, design elements, not an architectural style. The house with the black eaves and stucco in that in one example is clearly an outlier in whatever search you ran. Why would that be an outlier? I actually left off others that were described as Modern Farmhouse but were definitely outliers. Some were painted in colors, etc. In short, what they have in common is a simple, bright exterior with a focus on getting as much natural light into the interior as possible. So does any well designed house. So how does that make it an architectural style. I’m sure there are more commonalities, but I really don’t care whether the small contingency of detractors on this forum is willing to accept the term as a style, architectural or otherwise. I just don’t understand why they can’t stay silent if they don’t care to be helpful. It truly boggles the mind. Because it isn't helpful to just throw out terms that really have no meaning. Ideally people come here not only to help their own homes but also to learn and become a bit more educated. I'm sorry if you don't think that's important.
