16+ Standard Bench Depth Background. Get standard bench depth at target™ today. The depth must account for enough seating area, the back of the bench if it has one and the width of any pillows, cushions or other paddings you plan to put on the bench.
I have a bench along one side the length of the pool and a sun shelf at the same depth.
The bench should be at least 51 inches wide if you plan on having two people sit on the bench, but it can be 60 inches or more. Depth the depth of your workbench should, ideally, be no longer than your arm can reach across it. If you happen to be the type of woodworker that works with unusually large or wide pieces, then you may want to add a few inches. The standard under bench oven size is 600mm wide x 600mm high.
