Garage Workbench Dimensions

it's about that time where I need to sit down with a 12ver, a sheet of graph paper and build out my garage the way I want. Every garage i've ever worked in always had built in benches that just needed some TLC to get them where I wanted, but now I need to build them out by scratch.

Question is, whats the ideal height and depth for a workbench? I already have a basic plan in mind for the construction method so i'm pretty sure I've got that part handled but I'm open to any and all suggestions.

Thanks to everyone who contributes in advance.
