Our doors are all about 1/2 a foot below ceiling. Windows completely vary depending on their size. In main area they are a foot below but in office I would say more like 1.5/2 feet below ceiling

Would you have any pictures? Showing the difference between 1/2 ft and 2ft?

Ask your architect.

What is your ceiling height?

Sure I’m totally eyeballing this! Now looking I wonder if the windows are all the same.

Flo mangan mine are 10’.

West coast hopeful Thank you

Honestly, very much home style dependent.

Agree with @Mark Bischak, Architect. It should be already baked into the design.

With 10' wall heights we typically see 8' tall doors with windows set at 8'.

Thank you. So we currently have doors and windows set at 8’ but for windows, how high off the floor?

Surely all your windows are not the same size?

All depends. Over kitchen sinks, can be as close or approx 4-10” above counter, over nightstands and often in bedrooms, maybe 36” from floor, in more public rooms can go as low as you want, but under 2’ I think you need window opening control devices and under 18” I think they will need to be tempered glass.

Last I looked congress had not enacted a law on window placement, so you can do what you like. If you put them too close to the floor they will need to have tempered glass, depending on their sizes.

This is really between you and your architect, and has a whole lot to do with the style of your house. In some kinds of very formal designs you want all the windows the same size pretty much and everything lined up. In other designs they can be all over the place. In our English Arts and Crafts inspired house the windows are at at least four different distances from the ceilings and three different heights off the floor, none of them align with the doors, Though the door tops do align with a thicker divider between some of the big banks of windows. The windows are sized and placed to optimize the appearance and use of the room, while not looking haphazard from the exterior. This is with 11 ft ceilings. FWIW, I like the way it came out, but then I side with Emerson on the subject of "a foolish consistency...". It works with our design, it wouldn't work in a Federal style house.

We have 9’ ceilings and desired more light to come into the home so we set the headers up high and did 6’ windows. We didn’t want the added expense of a transom over our front door so we kept a standard 6’ 8” door and built up the trim above it. I love the added charm our windows have. We also lowered the header height on the sides of our house and we plan to put window boxes on the sides. So for your 10’ wall I would go with a 12-18” transom or a taller window(7’)

@Christian Arispe not Instagram or social media worthy photos but to give you an idea of inside and outside window header differences.

Big 6’ windows 9’ ceiling height.

5’ Windows set at 7’ on a 9’ wall

kitchen windows set at a high header height but of course shorter to account for 36” counter height
