Tanks this size are ideal starting points for anyone entering the hobby. In the United States 20-gallon tanks are available in “tall” and “long” varieties. The tall tanks measure roughly 24 inches in length and 17 inches in depth; the long tanks are 30 inches in length and 13 inches in depth. All else being equal, the long tank is better.
