Yes, and I would notice, and yes it would be a deterrent to me for resale purposes.

How is does having a wider hood affect the head area? Can you post your layout?

“for the hood to not poke out into head area.”

I am not following that line of reasoning. How would the width of the hood - side to side - affect the head area?

In any case, there is no point to having a hood narrower than the range because you will be spending money on a hood that doesn’t exhaust the burners at the sides of the 48” range. So, it’s money out the window. Also it would look really odd.

If your cooking is minimal as you said, why are you getting a 48” range? You could save money with a smaller range, or get a wider fridge instead to store your take-out. Wide fridges are really nice, and if I did minimal cooking, that’s what I’d get, not a range in a size suited for people who cook a lot.

You might get away with it not looking weird if it were a sleek induction cooktop but not a range. A range is too MUCH to ignore.

A smaller range makes more sense, especially with minimal cooking. Large ranges don't make a kitchen look more affluent; there is no reason to get one if you don't intend to use it.

My understanding is that having a gas range (particularly a powerful one, as most 48" ranges are) in front of a window is not recommended for a variety of safety reasons. Perhaps if you share your plan in the kitchen forum an alternative can be found?

For function: The hood/hood cabinet should be at least the same width (side to side) as the range/cooktop. Ideally, it would extend 2-3 inches wider than each side of range...but a 48"W range should have at least a 48"W hood.

For form: It would look odd, and like a major error in design to have the hood be 3" more narrow than the range on each side.

Being in front of a window is a whole other issue that you have hopefully checked your building codes / installation requirements for. Things such as climate (if you live where the glass could be extremely cold from weather and you heat it with the heat of range), window trim and window treatments are all things to take into account for fire code reasons.

I have seen it done in photos though, so make sure you know if it is to code for your area because there are safety reasons for the codes

Not just code, but combustibility of the window materials. You cannot have them in an area by/behind a range and most windows contain them.

Just because you can find a photo of someone having done this, it doesn't make it safe.

You need to make sure this window is higher than the allowable minimum for combustible materials. Look at the range installation documents.

As others have posted, perhaps you can post your layout.

It doesn't seem to make sense to have a 48" range located in front of a window with a sub-standard hood.

Anyone who really wants to use such a powerful appliance in the manner intended will be put off by the substandard hood as well as the location by the window. Not mentioned is the amount of unattractive gook that will be deposited by the window.

If you don't cook, why do you want this range? If you want this range to somehow appeal to a buyer down the road who genuinely wants a high end cooking appliance because they do cook, the layout will be a complete turn off.

Again, check your building codes and install manuals, but the height of those windows makes your plan look promising.

Back to your original question, make the hood at least the same width as the range.

Ah - the photo helps a lot! Shouldn't be an issue there.

That said, you do want to go at least the same width as the range for capture area and for aesthetics.

Does your local code allow a range under a window...many do not.

Talk to companies such as ModernAire. All their hoods are custom-built to order. They can definitely make a wide hood that is narrower front-to-back. I am sure they could also build you a wall-mounted hood that would fit the space that you have. So, you have a lot more options.

Having said that, a hood that is deeper front-to-back will work much better. Same as overlap on the sides, you need overlap in the front. Cooking plumes rise in an ever-expanding cone. For a hood to be effective, it needs to contain the entire cone or it needs to have guides on the side that direct the air (i.e. cabinets that come down on the sides).

What you can do to fit a larger hood is to raise it higher. We decided to mount our hood just above head height, but to then make it bigger. It works really nicely that way.

Can we swap kitchens? It looks fabulous.

Wow, it looks really nice! Congrats! I also like how you did your fridge cabinet.

Unless you avoided all wood in our exterior wall (unlikely), the island trim on the range is most likely in violation of building codes. Whether it'll damage the walls and/or set it on fire is a different question. Since you have tile on cement board, you might just get lucky and damage to the wooden framing remains minimal. But the building inspector should not have let this pass, if they paid attention.

There have just recently been several lengthy threads on this very topic. Here is one of them: [https://www.houzz.com/discussions/aurea-divine-quartz-cracked-dsvw-vd~5649974[(https://www.houzz.com/discussions/aurea-divine-quartz-cracked-dsvw-vd~5649974)

Alternatively, you could have spec'd deeper cabinets and pulled the stove forward from the wall. That's the solution we opted for.

'Normally', if you had cabinets adjacent to the vent on both sides, you could go with a 48" vent over a 48" range, bearing in mind you might have to put something on the cabinets (like a sheet of stainless) for heat protection. In your case, since you have no adjacent cabinets, a wider vent is preferred, like 54", so that the spreading effluent is still captured. It's really a function of height from the stove top, which is why a deeper hood is also desirable.
