My opinion only, and I'm not a professional decorator...I prefer the look of two lights versus three in general and especially because of your hood. If you like the look of the smaller one better, use that one. I have seen quite a variety in terms of size of pendants in relation to island size, so anything goes. Although I'm sure there is probably a "rule of thumb". But as long as you like the way it looks...nothing else really matters.

I would go larger if you are set on two pendants, otherwise they'll look tiny over the island. One way to to test the look is to make paper cutouts of different sizes and test them over where your island will be. Restoration Hardware's Benson pendants are similar, and Kichler Lighting makes versions as well. Here is a link to your pendants: VC Yoke Pendants

Kelleg i agree to using a similiar mounting height but if I'm seeing sources suggesting 30-36" above counter then add 3" for every foot that becomes more of a disparity than a few inches. I do have an electrician but I was trying to nail it down ahead of time so I don't drive him crazy before he comes to do the job. The pedants are large and are just under the max recommended for size of the room when I've done the math. I plan to do 2 . I won't know until I see them up and the problem is they are a little heavy and awkward. I'm going to try to see if I can get DH to just rest on top of a ladder or something so I can see. I've been trying to figure out how I could hang some beach balls from the ceiling to give me an idea Lol but I can't figure out how I can get up there! I even googled the cost to rent scaffolding haha. zorro I agree to some extent but after having a 24" pendant installed in the eat in dining part of this room I missed the mark slightly selecting the right size so I don't want to do that again. since that day I always saw something larger needed. The height I selected was fine at 36" off table so maybe I just need to address getting size of the pendants to fit the scale of the room? In hindsight I kept thinking I should have had the same size as what I had installed in my foyer. I guess I'm being fussy but I want it right ... just like you I didn't want to see bulbs in certain applications. I've read some great articles that have had some great guidelines that I had not considered here: https://www.bobvila.com/articles/21907-pendant-lighting-101/#.WRtHo_D3aEc https://www.google.com/amp/www.decoist.com/2013-03-21/hanging-pendant-lights-ideas-inspiration/amp/ The second one I agree with the point that your trying to almost bring the ceiling down visually so that it looks like a more normal height and also I'm trying to fill some of the empty space if that makes sense. I have plain empty walls where vault continues up and rather than hanging art thought it would be cool to have decorative lighting against that plain backdrop of wall space. Vinmarks it may just be what I like but again it's based on my experience with my current dining pendant being to small for the space and too much dead space above...just trying to find a balance. StanZ thanks I agree 100%. I'm 5'6" but my gang is on the taller side 6' to 6'3" i'm leaning to starting at least 36" but wondering how high after that? bbtrix great idea with balloons! Your look great. I definitely don't want vision obstructed either. I don't care for any pendants that low. I like how yours are placed. From that pic they look nice just above fridge with the white cabinetry as a backdrop. Also in first pic with balloons I do like that they are more down in front of the tops of the cabinets rather than floating in ceiling area. That picture helps! My pendants will hang the opposite way of your vault tho if that makes sense. How high is the vault at which your pendants are mounted from floor to ceiling?

If you have cardboard boxes laying around, I'd choose some that are about these sizes, maybe cut them down or add to the size with part of a paper bag, and literally string them up. There's nothing like a 3-d model to help you make your decision.
