Blue Star has a large oven, it can fit a full size (commercial) sheet pan in it. Depending on the size range you want, they have two ovens in the 48 inch and 60 inch models. Good luck on your search, I have been back and forth for several months (okay more like a year or so) and I just made a decision and ordered my range yesterday...

It might be helpful to tell us your budget. What width-- 30" or more? Gas,electric or dual fuel? Have you considered induction? What do you mean by 2 ovens?

I have always found that my clients love the 48" for a variety of reasons. First and foremost, they give 2 oven sizes, a small one that will preheat quickly and work well for every day meals/reheating and a large oven for holidays/entertaining. That flexibility combined with multiple top configurations can check most boxes.

60" ranges will have 2 duplicate ovens (with the exception of capital) and will run a small fortune because they are uncommon.

For all gas Capital and Bluestar both make wonderful performance oriented options (high power burners, larger oven cells). Capital especially if price is a concern. If brand is important, thermador and wolf are good gas ranges.

For Dual Fuel it varies a bit. Thermador still makes a nice one, as does capital. Many on here have issues with Wolf's ovens chipping, but I have never had a client call me on that. Be aware that Dual Fuel will run 30-50% more than an all gas and be less reliable in the long run.

Alternatively, I have worked on many projects with a 36" range with a HUGE oven, and an additional 30" single wall oven. This gives a good mix, where you can get a gas oven in the range and an electric oven in the wall. This is very popular in the NY market place.

Joe Henderson gave a great summary. The only thing I would add is that one of his suggestions of the 48" range will need to have a 48-54" hood for it. The kitchen will lose upper cabinet space to the hood, though in a large kitchen that may not matter. Also, such a large hood needs adequate ductwork, typically a 10" diameter duct, and some homes do not have that, and it will need to be added. The OP is doing new construction, so has an opportunity to ensure the ductwork is the right size. And of course a hood of that size is expensive.

Friedajuna is right (sorry for leaving it out). Keep your hood in mind. The larger and more powerful the range, the larger and more powerful your hood needs to be(and more expensive). That can be a bit of a trip up and is worth the time to do your leg work on if you are doing new construction. Hoods are also much more flexible in terms of brands and don't require a name brand on the front to work appropriately.
