Wooden slides offer near full-extension capacity while remaining quiet and unobtrusive. You can purchase these mating, dovetail slides or make them yourself with the help of a table-mounted router. While not entirely wooden, this track/glide combination offers smooth motion at a fraction of the cost of a set of metal slides.
Slide and drawer sizes
Most drawer slides are available in even lengths ranging from 10" to 28" with a couple odd lengths (15" and 21") thrown in. They also carry weight ratings. To choose the right length, measure both the depth of your cabinet and the length (front to back) of your drawer(s). Undermount slides are designed to match the drawer length. With the other slides, you typically get slides that are approximately 1" shorter than the depth of your cabinet.
