How many windows are there in the room?

I think two different size windows are fine, as long as they are not in the same wall.

There are 2 windows in each room, and no they are not on the same wall, but adjacent walls.

Thank you!

If they're the same width, you could hang drapes that would make the smaller window seem the same size as the larger window.... since you say the drapes on the smaller window would always be closed, they would look the same.

If that makes sense, lol...

I have 3 different sized windows in my bedroom. A full wall (3) of large casement windows on the west, 3 awning windows on the east, up high so the bed fits under them and then 2 large windows to the south with the top opening as an awning. They are the same height off the floor as the casements. I don't have any window coverings at all and all are wood with wood sills. It looks great.

I worked on a Mid century house that had high awnings on one wall and a traditional double hung on the adjacent wall.

In one room we put shutters on all windows. In the other we put a traditional full length drapery on the long casement window and an accordian shade that just kinda blended into the wall color on the awning windows. They were so narrow and high from the floor (and very wide)that a traditional full length drape would have looked a bit odd in this case unless fully closed all the time--which would have looked odd when the other was kept open most of the time.

we just had an addition built and the way the windows fall, we have 2 different sized windows on one wall. It looks fine.

We have different size windows in our bedroom. They aren't even the same height making it difficult to find ways to cover them. Here's a shot to give an idea. We are using mini blinds.

Thanks to all for your helpful input! Hopefully ordering soon in time for the tax credit!

When we replaced all of our windows with new Marvins, we installed large windows in our LR and Foyer, two windows (butted up against one another) in each room overall equaling something like 84 wide and floor to ceiling, or the maximum we could do according to code. Windows here cannot be completely floor to ceiling as it is a safety hazard? The thinking is someone could fall through? IDK?

In MBR and DD's room we have larger end of the house windows. By code in our town, you must install egress size windows in bedrooms, which are huge.

So along the back of the house every window is the same size, 4 in each bedroom, 1 in bathroom - which makes it look uniform with the back of the house downstairs windows - all the same size. I think so long as the windows along the same wall on, i.e., back or front of the house are the same size, it will look nice. We installed a triple window in DH's office and it looks nice from the inside and out when you look at the front of the house. It is absolutely a different size (as it is 3 windows together) than the other 5 windows across the front, but in keeping with the same length, IYKWIM?

If possible, I think you want to be able to look at the sides of your home and everything be complimentary on every side.

However, the gentlemen who built and previously owned our home did not ascribe to that particular theory and it wasn't a deal breaker - we bought our home anyway. Building it on his own, I think he must have put in 12 different size windows in the 2nd floor. I don't know if he got a deal or what, but it was a PIA when we went about the process of putting in new windows. Headers needed to be installed in places, sections of wall cut out, but in the end, I like the fact that everything looks more streamlined now. Plus, buying curtains is not the awful exercise it was previous to the install of our new windows:0).
