It's not difficult to measure for your kitchen cabinets but it's not easy either. If you are planning to replace your kitchen cabinets in the same configuration, you can simply measure the width, height and depth of each individual cabinet. You'll want to note which way single-door cabinets are hinged and you'll want to note which cabinet ends need finishing.
If you're planning to change your cabinet layout or configuration, you'll want to measure all of your existing walls, the height and width of all openings and your ceiling height. Make sure to account for your flooring height if your floor is changing or is not complete at the time of measure.
