The average clothes dryer lasts eight to 12 years. If yours is approaching that age, or if you are noticing it is not drying as efficiently as it used to, you might consider a new one. Here are some thoughts.

Gas or electric?

Gas dryers may cost a little more up front ($100 or so) and may be more difficult to install if you do it yourself, but they cost less to operate and over the long term are generally the better buy. However, if you need to install a new gas line, that expense could erode all of the savings.

Capacity

Standard dryers range from about 7.3 cubic feet to about 8.3 cubic feet. However, you can purchase compact units as small as 3.4 cubic feet and large dryers as large as 9.0 cubic feet. One general rule is your dryer should have twice the capacity as your washer. One or two people washing only light garments generally can get by with a compact unit.

Size

Most dryers are less than 30 inches wide, from 25 to 30 inches deep, and 35-45 inches tall. If you have that much space plus a few inches on either side and in the back, you should be fine. If space is an issue, you can check out tall, narrow units that can fit in a closet, or a washer and dryer that can be “stacked.”
