Unlike dining room tables or kitchen counters, no standard workbench height exists. Workbench heights can range from 28 inches to 38 inches. Workbench heights on the high end are suitable for assembling items and to function as outfeed tables for table saws, while lower workbench heights allow for more leverage for such jobs as sanding. If you’re not sure which height you need, use this literal rule of thumb—the benchtop should meet the same level as the knuckle in your thumb when standing with your arms hanging at your sides.
