Hi chittering5 we used the 25.5cm lights. Our island bench is fairly small at approx 1800x900mm. I actually purchased 3 (at much better price than currently listed) but felt it was too many for the space when I mocked up the (widest) diameter of the lights with paper cut-outs. Trying to decide if I can use the 3rd light in the bathroom or something without it looking lonely....

Like the previous comments it depends on use and the design of the light fitting itself. Also if the light has a narrow beam it may need to sit higher to throw a wider beam to light up the area you need lit up. Generally you would put it above eye level so that it doesn't obscure your view when standing. More often than not it is just a matter of where you think it looks best, most pendant lights have good adjustment so before its installed have the electrician hold it up for you at different heights and see what looks best.

Oh my goodness Kate! How did you do that??? Photo magic. Thank you so so much. Ok looks like the two it is bigreader. And yes Kate, I did not realise that the range hood is silver! Yikes. That will compete with the gold. And I have a silver fridge too!!! Eeek.

Also if i can avoid moving air con for now that would be great. The next phase of reno will be to take down the wall between lounges and put aircon on the front wall of the lounge as it's the only other outside wall it can go on. Here might be my plan for now. I'll put the kitchen in place and figure out if i need to add more storage to office area. Will add range hood and a few long open shelves like in the image below (and is also the look i'm going for decor wise)
