Depends on who and what will be moving through the opening.

28" used to be the standard size for a door to a room that didn't need large furniture moved into it (e.g. a bathroom). But if you're considering aging in place, it's worth implementing ADA accessibility guidelines. And that means a significantly wider doorway-- or a reach-in rather than a walk-in pantry.

If youre going to be carrying things through the door you might want some width. Nothing like smashing your fingers between a case of water and a door jamb.

Be optimistic, 32".

Can you make it a pocket door?

Yes we could make it a pocket door.

Mark Bischak, how is 32” optimistic? versus 28? I want to follow your train of thought.

The pocket door will free up a lot of space, then make the door as wide as you can. You will hate every day that you have to squeeze into your pantry. Good luck w your plans

If you look at his sketch, it looks like a pocket door makes sense there. I have a few in my home and modern, quality pocket doors are smooth, and sturdy.. You do have to make adjustments when hanging items on a wall housing the door, but its certainly doable.

@Mark Bischak, Architect, did your train of thought derail? ;)

M Riz, good to hear the quality is better than it used to be. My dad was a building contractor and he wouldn’t install them they were so problematic back in the day.

I think we will go with a pocketdoor. Thanks for all your thoughts everyone.

Get a quality door, dont cheap out.i have 8 foot solid core pocket doors. They are incredibly smooth when opening/closing and the way that they are attached to the rail, they no longer derail. I checked out the mechanisms while my home was being built and i am confident they will operate as intended for many years..

A 28" actual opening pocket door is comfortable where I have them. Based on your drawing you have the option of angling back the shelving from 90 to 45 degrees at the opening for access.

IMO corner pantries are a huge waste of space and no matter how wide the door is.

24" but we will typically use 28-30" if there is room.

About corner pantries being a huge waste of space, i have had similar thoughts, but because of various aspects of this particular kitchen layout it will serve me well i think.
