To properly dry laundry, a dryer needs to have air. This needs space and that's why the drum needs to be larger.

In a condenser dryer the condensed water vapour is drained and collected in an internal reservoir. In a vented dryer the hot, moist air is drained through a hose, for example out of a window. A vented dryer is cheaper to use than a condenser dryer

In general it is possible to directly stack a dryer and washing machine directly on top of each other. This only works with front loading models. However, it is advisable to use a fitting accessory to do so. This will prevent the machines from vibrating and falling off and also prevents damage to the bottom machine.
