34”?

Actually the specs say the rough opening is 33”... I know I am only talking 3” but just not sure how they will look and if anyone has any pictures or experience with the smaller window

What does the home look like? Context certainly helps with decisions.....................

Many farm houses I am familiar with have double hung windows. Do/did you have professional help in designing the house?

Here is the front elevation of the home. The drawings show double hung but we have decided to move forward with casement and one simple vertical and one horizontal space bars

Ask your designer to show you several front elevations with various windows.

And I'd ask to see what bringing the B&B down like I show in the left gable (for all gables) and raising the porch roof.

Note how the gables are forward of the wall between them.

36" is really wide for a casement. Have you thought about this? Even 32" seems wide.

"The drawings show double hung but we have decided to move forward with casement . . . "

Who is "we"?

I too strongly recommend staying with the double-hung windows if you're "going for the farmhouse look" as you say. I'd also recommend ditching the black windows, whatever their style. It's the big current trend of course but I always tell my clients to avoid trends but if they're trying to follow current trends, they're already too late.

The two upper windows shown here are 31.5 x 60. If you go any larger, it is recommended that you have twin casements.

If you want black windows, in order to avoid big blank holes, make the sash black and the frames white. This will do more to create a slim looking profile than casement vs double-hung. The trend toward black frames is no doubt due to builders offering inexpensive windows that cannot be ordered in two colors.

Clad wood window sizes often increase in 4" increments so, if that were the case, the RO choice would be 33" or 37" which is a substantial difference. For a Marvin Elevate window the glass widths for these two window sizes would be approximately 27 " and 31".

The largest Elevate double-hung would have a RO width of about 55" and a glass width of about 48".

Before you decide to use casements, draw the opening swing on them. That could be a problem with 3 windows in a row unless you make the center window fixed. In any case, the house will not look like a farmhouse when the windows are open.

"the house will not look like a farmhouse when windows are open."

I don't think it will look like a farmhouse when the windows are closed.

The house is already struggling to look like a farmhouse because of the paired and tripled windows. Making the windows casements will make it worse. Farmhouses don't usually look like beach houses. nor do they have double front doors. You could drop the farmhouse pretense and go for a Swiss/French tradition where the casements would be appropriate.

For some all white siding and black windows is considered “farmhouse look” regardless of the architecture.

What did you end up doing curious? Any pictures ? Did you go with the 31 or 35 inch wide casements?
