I have 9’ ceilings & just measured door openings - floor to inside of door jamb - 6’8”! The proportion looks right to me. All my doors have wider wood casings around & baseboard is 6” & do have crown at ceiling in entry & great room. My house does also have arched openings between great room & kitchen & to the two hallways opening off great room & end of entry so those are taller which gives more feeling of height & openness. I bet there are other upgrades ypu might want to spend $6800 on? Extra water spigots outside, more concrete walkways, better under cabinet lighting in kitchen or upgraded light fixtures? So many things to add when building & not sure taller doors worth cost. Seeing floor plan might make difference & then maybe only for first floor.

I think people will ask you what your trim will look like - - both around doors and if there is a crown moulding.

How tall are the people in the house going to be?

For a 9ft ceiling I would not use a door taller than 7 ft.

I'd upgrade to solid core doors, whatever you choose.

We upgraded to 8' and I like it, but YMMV.

Standard height for 9' looks fine.

I prefer the taller doors, but either choice will look fine. You could also do the taller doors downstairs and standard upstairs

This topic comes up frequently here. You can search for it. There is no general consensus. :-(

My pref: 7' doors are a nice upgrade for 9' ceilings.

I would definitely do it on the main floor. I've seen 8' doors in 9' ceilings and it gives a more airy feel for a main floor. I would not spend on it for the bedroom floor though!

Taller doors on main floor are more luxe look. What is style of house? Modern or transitional=taller with compatible trim and baseboard. More traditional or craftsman 6’-8” is best. But don’t spend more for second floor. Save money for wow factors on main floor!

Thanks for your responses, appreciate that.

I will say house does have more modern look to it, i am attaching pictures from the floor plan.

Below is the information i could found on window casing and baseboards

Contemporary 2-1/2” MDF window and door casing

Contemporary 4-1/2” MDF baseboards

I think eight foot doors with 2 1/4" casing would be out of proportion.

I agree with @Lyndee Lee - go with the standard height doors - I wouldn’t get 8’ doors on 2nd floor & there aren’t any doors in ”open” high view places on first floor. Do you know the height of the bulkheads on first floor? You have 3 & the height of those openings will, I think, make a difference to the open feeling on lower floor. As I mentioned in earlier post, my home has arched openings / bulkheads which are 7’ at ends, & 7’10” in middle. If they had no arch they’d be 7’10” straight across. My point being that my home’s bulkheads are higher than its doors

With your layout, standard height (6’-8”) is best. Not worth the extra cost. However, I would do front doors 8’ high.

I lived in a large Greek Revival house at one time and they were very big on proportion. (They had been converted into condos but I lived on every floor at one time or another so I am familiar with all the proportions. Keep in mind that the lower floors had very elaborate millwork and ceiling treatments that got simpler and simpler in a systematic way as you ascended the floors of the building.

Floor one: 14 foot ceilings, 8 foot room doors, 11'6' windows and pocket doors.

Floor two: 12 foot ceilings, 8 foot room doors, 10 foot windows and pocket doors

Floor three: 10 foot ceilings, 7 foot doors 8'6' windows

Floor four 8 foot ceilings, 6,8" doors 8 foot windows.

Most of my downstairs is 10' ceilings except in the hallways. My hallways are 9' ceilings and I have 8' doors throughout the downstairs. Here's what an 8' door looks like with a 9' ceiling.

Upstairs I have 9' ceilings throughout and put in 6'8" doors. Personally if I had 9' ceilings everywhere downstairs, I would have done 6'8" doors. 8' doors feel a bit too close to the ceiling.

My advice is this. If you want those doors and are just here for the affirmation that you will never get, just do it. Make your home what you want. There is no changing your mind later when youre sitting on your couch and wishing your doors were taller/shorter..I have 10 +12 ft ceilings and I have 8 foot doors. You have to really think about what YOU want in this instance as either door will work. Best of luck w your build.

A standard 80 inch door on an EIGHT foot ceiling gives you header of 16 inches.

An eight foot door with a nine foot ceiling gives you a 12 inch header.

There no decorative purpose to header. ........not above a door, and more important? Not above a window as long as there is room for the trim you want.

The taller the openings? The more open the house shall feel. Are you going to miss four inches of boring header/drywall? I doubt it. : )

Put the eight on the main floor and the standard on the second floor . Beef the casings/base to 3/34 and 5/3/4 with simple 1 x4 and 1 x6. . Your trim seems skimpy, regardless door height.

Nothing lives in isolation.......

Will the windows be at a similar height as the doors then, whichever you choose? What did your builder say about that?

With 9' ceilings I'd personally save the money and go with standard size and use it for upgrading somewhere else or buying new furniture.

I would do an 8' door or standard with transom over it for entry door.

We went with 9 1/2 foot ceilings in our house. We knew we wanted crown molding and wide baseboards. This is the entryway the door is 8 ft. The bedrooms and dining room, kitchen doors are 6’8” with transoms over them.

Meant to add, Congratulations on your new home it sounds like it’s going to be absolutely beautiful.

Since this is a new house, have you considered having a bathroom for every bedroom? Or us it too late for that? Apologies if that sort of question is a faux pas. Still learning...

My current house has 9' ceilings with 80" doors, not the one we are building, it is absolutely fine. If you have 10' I would go for 8' doors anything else - no.

Our (Seniors) home has 9' ceilings; 7' X 3' doors; 4" window and door casings; 8" baseboards; deeper moldings in Foyer, LR, DR and shorter ones in BRs, baths, kitchen, back hall. The width has been a wonderful feature for us and for movers and delivery men. Our entry door is 8' X 42" archtop. (I'd like 7' doors with the lovely entry door w/transom in your photos.)

I'd skip most of the bathtubs on your plans; most are only used to bathe very young children. In my area it is against code to have bathroom doors open into the chamber for safety reasons. (If someone faints and falls you can remove hinges to access them.) Few if any children/teens will use a bathroom at the same time -- skip double sinks.

Look to see where you can add windows. LIght from at least two directions creates a more pleasant room.

You will curse that narrow garage every time you back out of it. There's also no storage for kids bikes and other paraphernalia or garden tools.
