Kitchen design is a precise art. To make a functional space, every inch counts, and it can be difficult to remember all those tricky measurements. Here are some helpful guides and infographics collected from around the web to help you make the most of your space:

Work aisles and walkways: Work aisles (where a person stands during food prep in a kitchen) should be at least 42" wide, and walkways should be at least 36" wide. For two cooks, expand the work aisle to 48".

Countertop height and depth: 36" high is standard (with a standard bar height island clocking in at 42"); the average base cabinet depth is 24", and the average countertop depth is 25".

Landing areas: An ideal prep area is 36", but try to maintain at least 12" as a landing area next to your cooktop. 18" is a good width next to the sink.

Work Triangles: To maximize efficiency, try to balance the distance between your workstations so that you have to use the least amount of steps while still having a proper amount of work space. The distance between any two appliances should be no less than three feet and no more than seven feet apart.
