Cut some mock ups out of white paper and stand back and look at it.

I am doing 1.5 inch on my perimeter and 2.5 inch on my island as recommended by my kitchen designer.

This is a personal choice however as you have a more traditional styled kitchen I would likely use the more tradition 1 1/2" built-up meter edge profile. We usually only consider thicker profiles in more modern/contemporary styled designs.

1,5 inch = 3,81 centimeters .

When the average thickness of the slab is 3 centimeters , consider the visual difference between 3 and 3,8 cm before making the decision . It is very slight for sure.

My personal suggestion to cases like this is to go for at least 2 inch , so that the visual difference is significant and obvious to everyone.

Our fabricator suggested 1.5 on perimeter and 2 on Island...I said I wanted 2.5 throughout. I think it's a more clean and cohesive look. It's completely a 'personal' choice.

Thank you Nick, it is very helpful for the future readers!!

This is an older post, but since it's been brought back.....

For anyone considering this, keep in mind how much this will raise your working surface height if working with standard height bases?

Also, if you have this at your range, you need to compensate for your 18" height from countertop to underside of upper cabinet/light valance.

@Design Loft Bracebridge a mitered edge doesn't increase the thickness of the stone, it is mitered to look thicker
