I'm 6'3", and have the Wolf 36" 4 burner/griddle rangetop and the Wolf 42"x27" hood (900 cfm internal blower). It's recommended that you go with a 42" hood for a 36" range or rangetop so that you have better capture of the heat and smoke/grease. The variables you can play with are the mounting height and the depth of the hood...24" or 27". It's also recommended that you mount the hood around 27" above the range...check the Wolf specs. I also thought I'd be bumping my head and really uncomfortable cooking, so I raised it to 28 1/2". I was concerned about not getting cooking grease all over the house, so I didn't go any higher(open kitchen/great room floor plan.) I also had a soffit beam there that couldn't be removed, so that limited my mounting height to nearly the recommended distance. It works great at that height, and if it was any higher above your head you'd probably not get much effective capture. Measured from the ground, mine is mounted so the bottom of the hood is around 65 1/2" off the floor, about 5 feet 5 1/2 inches. I cook mainly on the two front burners, and use the back burners for simmering, so I can easily reach and see inside the front pots, and still reach the back pots. I definitely have to stoop to get under the hood to look directly down into any pots on the back burners, but honestly, I really don't do that much...I can still see the contents from the front of the stove. Once I got used to the configuration, it became second nature. I agree with the previous poster, and I did the same...mock it up with cardboard and lines drawn on the walls.

Check out Dacor ranges on AJ Madison. They have slightly less capacity and the couple I glanced at were around 24" deep.

I ended up with a whole vent hood ideabook on houzz. Here are the ones without flanking cabinets: [Traditional Kitchen[(https://www.houzz.com/photos/traditional-kitchen-ideas-phbr1-bp~t_709~s_2107) by Lake Oswego Interior Designers & Decorators Jenny Baines, Jennifer Baines Interiors [Traditional Kitchen[(https://www.houzz.com/photos/traditional-kitchen-ideas-phbr1-bp~t_709~s_2107) by Sarasota General Contractors Perrone Construction [Traditional Kitchen[(https://www.houzz.com/photos/traditional-kitchen-ideas-phbr1-bp~t_709~s_2107) by Bethesda Kitchen & Bath Designers Aidan Design [Traditional Kitchen[(https://www.houzz.com/photos/traditional-kitchen-ideas-phbr1-bp~t_709~s_2107) by Daniel Island General Contractors JacksonBuilt Custom Homes [Contemporary Kitchen[(https://www.houzz.com/photos/contemporary-kitchen-ideas-phbr1-bp~t_709~s_2103) by Birmingham General Contractors Structures, Inc.

Since no one has answered this, I'll take a stab at it... We have a 24" deep hood over a standard cooktop. It's 30" off the cooking surface. Our counters are the standard 25-1/2" deep (24" cabinet + 1-1/2" counter overhang). We are a tall family (ranging from 5'10" to 6'5" and still growing) and we do not bump our heads on the hood (well, my DH did once when he was peering up into it and didn't lower his head enough to get it out!). If your range is 30" deep, that's 4-1/2" deeper than our counter so I think 27" deep will be fine (that's only 3" deeper than ours). If you grill or do high-heat cooking, a deeper hood is often recommended anyway! This is what a 24" deep hood looks like over a standard 25-1/2" counter (36" wide cooktop). Vent-A-Hood: SEPH18-242 You might consider pulling the range out...do you have room to make all your counters 3" or so deeper? Those extra 3" make a huge difference in work space...so if you could pull the counters out, pulling the range out would be natural and look "planned".
