The short answer: Farmhouse windows are rarely square, often tall and narrow, and almost never the size the tape says at first glance. The treatments that work out here are the ones measured to each opening individually, mounted to suit each frame, and finished in materials that shrug off a working household. I measure Calloway County farmhouses myself, and this is what those windows have taught me.
What decades of settling does to a window frame
A farmhouse that has stood since your grandparents' time has been moving that whole while, slowly, the way old houses do. Frames rack out of square, sills slope, and layers of paint change the real dimensions of the opening. Order a blind to the width at the top of one of these windows and it may jam at the bottom, or hang with a wedge of daylight down one side. This is why I measure every opening at multiple points and check the diagonals, and why the numbers for two windows that look identical from the yard are almost never identical on paper. In an old farmhouse, every window is its own project. Treat them that way and everything fits. I also check how each sash operates while I am there, because a treatment should never block a window you still open for the breeze.
Inside or outside mount on a settled frame?
This is the biggest single decision in an old house, and it changes window by window. An inside mount looks trim and tailored, but it asks the opening to be reasonably square and reasonably deep. An outside mount hangs on the wall above the window, covers the whole opening, and forgives a crooked frame completely, because the blind hangs level from the bracket no matter what the frame beneath it is doing. I wrote a full guide to inside versus outside mounts in older Kentucky homes, and farmhouses are the houses I had in mind while writing half of it. In practice, most of my farmhouse jobs end up mixed, inside mounts where the frames allow it, outside mounts where the settling has won.
Tall, narrow windows and getting the proportions right
Old farmhouses favor tall, narrow windows, usually taller than anything a modern builder installs. Treatments have to respect that shape. On narrow openings, wider slats keep a blind from looking busy, like too many rungs on a ladder. Fabric shades on tall windows need proper lift systems so raising them is not a chore, and a cordless lift or a motor makes a tall window pleasant instead of an argument. Where several narrow windows stand in a row, I keep headrail heights and treatment styles identical across the set so the wall reads as one composition, which is exactly how those windows were designed to be seen from the road. An outside mount can also cheat a skinny window a little wider to the eye, a useful trick on the narrowest ones.
Privacy when the nearest neighbor is a field away
People assume a house with no close neighbors does not need window coverings, and then dusk arrives. A lit farmhouse at night is visible across a surprising distance, and anyone driving the county road gets a clear look into any uncovered room. Meanwhile the long sightlines mean you cannot see who is looking. The fix is ordinary, room-darkening or privacy-lined treatments in the rooms you live in after dark, bedrooms first, then the kitchen and living room. Daytime is the opposite story. With no neighbors, you can run everything wide open and enjoy light most subdivisions never see. The right treatment gives you both without a fight.
Finishes that survive a working household
A working farmhouse is dusty in ways a subdivision house is not. Field dust, wood stove ash, mudroom traffic, dogs. My default in the hardest-working rooms is faux wood from our blinds lineup, because it wipes clean with a damp cloth, does not care about kitchen steam or canning day, and takes a knock without showing it. For the living room and the rooms where the farmhouse look matters most, woven wood shades earn their place, natural texture that looks like it belongs against original trim and plank floors. Real wood blinds still have a home in dry rooms where their finish stays happy.
What I install most around Murray farm properties
Out past the edge of Murray, through Calloway County and toward Hardin and Aurora, the pattern repeats. Faux wood blinds carry the kitchens, bathrooms, and mudrooms. Woven wood or fabric shades warm up the living spaces. Bedrooms get room-darkening treatments, and cordless lifts go everywhere there are grandkids. Motorization shows up more than people expect, usually for one or two tall or hard-to-reach windows rather than the whole house, and the motors hide inside ordinary headrails so nothing about the look says modern gadget. The through line is simple. Every one of these was measured at the window it hangs in.
Where I would talk you out of something
A few honest warnings from jobs I have seen. I will not sell real wood blinds for a farmhouse kitchen that sees serious cooking and canning steam, because the finish and the slats suffer, and faux wood there looks nearly identical and lasts. Unlined fabric on a west-facing window takes hard afternoon sun and fades young, so those windows get liners or a different product. And if your frames are badly deteriorated, rotted sills, glass loose in the sash, I will point it out before hanging anything, because a beautiful blind on a failing window is money in the wrong order.
If your place is anywhere in Murray or the wider county, from downtown Murray out to the Kentucky Lake side, I will come measure every odd, tall, stubborn window myself, and the consultation is free.
