It's really dependent on how much you want to put into it and how much space you have to work with . My "work" bench (in the upstairs of the garage ) is 30" x 12' , that being said I have about 30" x 20" of workable space, it has a tempered glass panel that size to work on , durable and easy to clean . The rest is cluttered up with a TV , stacks of projects in containers , parts bins , supplies ( scrap styrene , a rack with new Evergreen packs , aluminum & brass tubing , tools and various boxes of cars ) and a display case hung from the wall . The bench itself is cantilevered out from the wall with diagonal supports so I can move a rolling chair the full length . It has electrical outlets mounted below the top surface , to the face of the bench for easy access . I also have a Harbor Freight tool box that sits next to my chair to hold all of my tools , supplies and detail parts I'm not using a any given time . I have 2 4' double lamp fluorescent fixtures centered over the actual work area and a desk mount lighted magnifying lens on one side . I'm a firm believer that we're like fish and grow to our environment , the more room you have the more junk you accumulate . You just have to decide how far you want to go .
