While oak gliders are available in several sizes, the standard measurements for a glider rocker are 26 inches long by 25 inches wide by 40 inches high. The inside seat dimensions are typically 20 inches wide by eighteen inches deep. So, when you're looking for oak gliders, be sure to take these measurements into consideration. If you need something more substantial, don't forget the wood construction will make the glider heavier. Because gliders take up less space due to their lack of padding in comparison to a standard rocker recliner, they’re easier to work into living room and bedroom designs.
