the inside dimensions on 24" ovens vary quite a bit from brand to brand. Everything fits (just barely) in my whirlpool 24" double oven. but it wouldn't fit in some other brands.

Ditto what Qwertyui said. Old 24" ovens weren't as well insulated and didn't have convection contraptions. That said, you should still be able to find new 24" ovens that will suit your needs and your cooking style. If you're getting new doors you might be able to steal a little from a neighboring cabinet. What others here have done is taken their big roasters or baking pans or whatever on their shopping trips. That will tell you even better than a tape measure.

You're not going to find many options in 24" ovens. You'll have lots of choices at 27". And then there's resale ... Most people are going to want bigger than 24" and would have a lot of work to do to install one. I would try to squeeze out the extra 3".

I have a 24" double oven (gas) that is on its last legs, and it is one of the primary reasons I really want to remodel. I wanted to just get a decent cooktop and replacement wall ovens to tide us over until we had amassed the funds for a really great remodel all around, but I can't replace the darn things. NOTHING fits without major cabinet modifications. Gas wall ovens are too short; electric wall ovens are too tall. And as far as I can tell there are only about 3 different choices in the 24" size. If we could fit a 27" double oven, we'd have plenty of choices. Alas, no such luck.

I guess my point is: go with a 27" or better yet a 30" if you can fit them. Much better to go with something that's a more standard size with more replacement options, should you need them in the future.

I had a 27" oven my larger cookie sheets and roasting pan wuldn't' fit in at the last house. The did fit in the 27 that was in this house when we bought it -- if only the ovens had both worked.

If you are looking at a 48" cooktop and at least one oven, why nt get a 48" range and have one larger and one smaller oven? I would have done that in a heartbeat if I could have used low ovens well.

the house we purchased has a 24" oven. the only reason it didn't matter to me is because the entire house is coming down. if resale is not in your immediate future you should do what you like. but if you plan to stay only a few years i'd strongly reconsider ...unless you're selling a knock down. jmo, though.

Agree with the others. The issue isn't the oven cavity size, but the (increasingly) narrow range of replacement options later.

I am trying to decide between the 48" stove with double ovens, but I would lose a lot of cabinets that I really like so it is a trade off. I thought I had decided to do that and then I began to think...so confused! We are not planning on moving for at least 20 years...this is our "kid home" so anything we do would be for us.

24" is the norm in Europe. I have a much larger one at the moment, but I am downgrading to a standard 24" in the new kitchen. I have had a 24" oven before and never had any problems. You may need to look up some European cookware to go with it!

I agree with fondantfancy: when I moved to the US I couldn't believe the size of the range/oven: it seems like heating wasted space (and taking up useful space). Maybe for the enormous Thanksgiving turkey if you feed masses? Otherwise I wouldn't bother if you've not had a problem before now.

Just want to clarify -- my problem with the 24" oven isn't the cavity size. I haven't had any problems fitting anything in the 24" wall oven. The problem is I can't replace the darned thing because there aren't any options in this country for a 24" double gas wall oven that will fit. I have searched extensively and have been able to find only 3(!) 24" wall oven combos on the market at all. You will have substantially better options at 27" or 30", and a better chance to replace it later should the need arise.

Have you looked at the Delonghi 24" ovens. They also have a 24" double oven.

Ikea sells three 24" ovens made for them by whirlpool with the brand name Mumsig. They are much more affordable than the KitchenAid or Delonghi brands, but I have no knowledge of the quality. You can buy three or four Mumsigs for the price of the Delonghi though...

We had a 24" oven which was one of many reasons we're now remodeling. However, 2 might be just fine. If you have the room, go for the 27" ones. That's was I'm doing: a double 27" oven. Can't wait. And I agree about better choices in the larger size. A.

Gaggenau has a beautiful 24" oven with a side opening door (right or left hinge). The design is similar to the Apple I-Phone. They also come in 30". Gorgeous ovens!

Last year when my husband finally found a good deal on another 24 inch oven to replace our 30 year old 24" we were happy to have it. We cook BIG turkeys in our roaster with no problems. The only thing we can't handle is one of those enormous pizzas from Costco. However, having had so much trouble finding that replacement, I would suggest you try to fit the 27 inch if you're going to remodel anyway.

I have a 24 inch gas oven that's probaly about 35 years old, and it holds every large pan I have, and I'm the one making the Thanksgiving turkey every year.

Having said that, however, I have been going shopping for the new ovens (double wall) I'll be getting, and the cavities of the 30 inchers don't seem that much larger than what I've got now. I think it's probably all about the the added insulation and convection doodads that other posters have mentioned. I would go for the 27 inch, at least, if I were you.

It also seems like every year fewer and fewer companies make 24 inch ovens. My daughter needed to replace hers about 4-5 years ago and she had more choices (but not many) than my SIL who needed to replace hers last year.

American's like to heat air :) That's why all of our ovens are so huge. We're actually going with two smaller ovens inside dimensions (about 15.5 wide by 18.5 deep and 12" high) and a warming cabinet. You can cook a 25lb turkey in this size oven easily and it will taste better because you weren't surrounding it with hot air which dries it out.

We entertain A LOT and this is plenty of oven for us to serve 20 guests from.

After reading this post, I changed 30" DO in my layout to 27". I was happy because I sort of needed that extra 3 inches for a drawer base. Then I had a contractor look at my plans and said I would be sorry if I chose a 27". He says his wife still gripes at him for not putting in the 30". Please tell me not to listen to him!!

Don't listen to him. 27" is plenty big, especially for a double oven.
