You need to be aware that the choice of switch plates for a 4-switch row is not as wide as for double switches.

If you can find a plate 4-wide that you like, it is not all that uncommon.

Putting in a pair of doubles looks a little less 'finished,'
but if you put them far enough apart vertically to for switch plate clearance it may look acceptable, especially if you want a plate style not available in 4-switch configuration.

You could also put the switched on opposite sides of the door as a 2-2 or 3-1 (your choice of odd man out).

OK, I will stack them, the most-used switch pair on top. That will be less confusing for the user and give more plate options.

They will have to be on the same side of the door because of a window adjacent to the door.

Thank you.

4 position plates are not that hard (I've got several of those in the house). I have one five position box in my kitchen in the other house and finding replacement switch plates (even plain white) is always a special order.

"4 position plates are not that hard (I've got several of those in the house)."

Four gang switch plates come in far fewer styles then singles and double.

Even triple are not available in many styles.

If you are wiling to use ANY style it is not a problem, if you have a particular style you want to use to match others it can be a PITA to find larger plates.
