Optional note: As you can see, the right side of my cabinet is right against the wall, so I did add a 3″ spacer trim board to that side to make it easier to open that door without feeling super tight (I’ll show you how). You won’t need to do that if you are in a free-standing area, but you may consider it if one side is against the wall like mine and you want to move it out a bit. It is one extra step, and you need to add that into your total width measurements, but it helped a lot since I had a wall and a window in that corner.
