Will you also be making sure all upholstery is the same throughout house? Is every light fixture the same? Of course not. So not all metals throughout the house need to be the same. It’s safe to keep some families the same, like doorknobs or cabinet pulls, but just because the toilet paper holder in the guest bath is nickel doesn’t mean the kitchen faucet needs to be nickel too.

Who visits you? I've never had anyone going from room to room comparing the drapery rods in one room to the door knobs in another.

It can be hard to visualize all the details at this point.

We have a full 3 story home, and for the most part, I like consistency.

We have silver nickel for the door hardware (handles, knobs & hinges), except for 2 exterior doors that lead to the back patio. (Those are both black.)

All of the bath & kitchen cabinet hardware and faucets are in a silver nickel or brushed nickel finish.

I used a matte black finish for all the drapery rods, and most of the ceiling fixtures.

(Although not all windows have rods.)

But I've started to bring in a little more warmth and interest with some antique gold or oil rubbed bronze.

It also depends on the overall style of your home. For example, in a modern or even MCM home, I would expect fewer finishes than a traditional or farmhouse style.

Light fixtures need not - should not - match throughout the house. You need to get the right size, shape, color for the room or area it is in. Same metal will limit your search and creativity too much.

Unless you live in an eclectic home, I'd match door knobs throughout. But they could be nickel, steel, or oil rubbed bronze. Think carefully about the style of your home and which knob finish will look best.

My sister has different pulls on every cabinet pair in her kitchen. They are truly unique, but even with that I love when someone who has been to her home a dozen times finally recognizes that she doesn't have normal pulls and knobs.

So the comment below that no one else will notice is 1000% correct.

They also don't notice the pull on her dining room chandelier is a kissing frog.

I certainly wouldn't want to be limited to using the same exact finish on everything throughout the house. That would be boring. I do think that, on a given door, the door knobs should match the finish on the hinges. I guess it would be an exception if the knob itself were something like glass, while the rest of the lockset or whatever you call it would match the hinges.

My home is MCM and I have mostly brushed nickel finishes, but Costco had Hansgrohe shower sets that were chrome. I had no issue saving a few hundred dollars each and getting chrome instead of brushed nickel. The hardware on the closets in the hallways and bedrooms and the guest bathroom are vintage Amerock copper pulls from the 1960s.

I love them and they are staying.

I got a black door lever for my cranberry storm door, my sliding glass doors have handles that match the doors and I bought brushed Nickel hardware for the rest of the doors.

My storm door had an oil-rubbed bronze handle when I bought the house. I didn't keep it because the finish was worn. I had oil rubbed bronze in my master bath in my last house and had issues with the finish as well. My sister also has had issues with oil rubbed bronze not looking good after a few years of use.

I love the look, but I fear the issues and don't want to buy hardware again in 5 years.
