I need to see a floor plan . Do you have an island or is this it for counter? IMO wall ovens work best where there is room for one and never buy a wall oven with a MW attached

if the 24 in is not shared w ”beside sink” or beside range i think it will work. you need more if it is shared space

It is difficult to advise without seeing a plan of the rest of the kitchen. Everything is related to everything else in a kitchen plan, so your question is in too much of a vacuum to give you accurate advice.

On another topic, as @Patricia Colwell Consulting said, wall oven stacks with microwave are a bad idea. The MW is placed too high or too low, and if they are one unit (you did not provide specifics), if either the oven or MW breaks, the other one is rendered useless as well. You mentioned you have a pantry - think about putting the MW in there.

The 24 inches would be dedicated counter space, not shared with a sink or range. There's also an island with uninterrupted counter (and no seating) right behind this area. I was just curious if there are standard guidelines for counter space next to a wall oven.

I think it's plenty. Consider how you use your oven now and if you'd personally need more. I know I wouldn't. (Even though I have landing area by the oven stack, I usually use landing area on the nearby island or even lug stuff from oven to range and don't mind a bit.)

My "stack" is a single wall oven with a microwave above it. I am short and gave some thought to the height of the appliances.

I shouldn't admit this, but my oven is used almost exclusively to cook frozen pizzas that are smaller than 24 inches in diameter :)

What is next to the 24". As others have posted, much depends on the floor plan.

What would you be giving up if you enlarged the space?

I have a small kitchen and so I don't have much free counter space in total but one learns to work with the limitations of the kitchen. It also depends on how far away other counter space would be since you could move items from one place to another as necessary and the landing spot adjacent to the oven is really only critical for taking out stuff directly from the oven as generally you can move it from there if you need to free up the space.

I've found a few older threads relating to this question, and was amused & surprised to read how many people turn around and use their island countertop as the landing space regardless of how much adjacent counter space they had. I'm inclined to think 24" will meet my own needs, but was curious how that compared to guidelines and whether people would react with horror to the idea of counter space on just one side.

I only have a landing space on one side because there is a construction beam on the other side so the only thing that would fit is a narrow "pantry".

In my life I never considered it to be an issue. Prior to my remodel, I had a stove that was next to a wall and so the only counter space was to the left. I have cooked in kitchens in which the only counter space was on the top of the stove (when I didn't have wall ovens).

With the oven door open and you in front the distance to the island is usually closer with fewer moves.

Thanks, all!

@Fori - I've been known to bake cookies on occasion, in addition to frozen pizzas. My cookie sheets are also less than 24 inches wide :)

Sounds like the 24" of counter is a cave between the oven stack & the pantry. I would think that the island behind will feel like the most natural place to land oven stuff. Because it will feel more open. And be a better space for removing cookies from cookie sheet to cooling rack. And better for whacking up that pizza.

Without seeing a plan, I'm going to speculate that a bigger pantry might be better use of the space instead of that small slice of counter top.

Sounds like plenty of options between the 24” counter space and the island
