What Is the Average Waist Size for Women?

As of January 25, 2010, the average waist size for women is 34 to 35 inches, and the average dress size is 12 to 14, according to Pamela Peeke on WebMD. In the 1950s, the average woman's waist size was only 24 to 25 inches.

As of 2010, the average woman weighed between 140 and 150 pounds. In the 1950s, the average woman weighed about 120 pounds. A uniform sizing system for women's clothes was used until 1983, when it was stopped by the U.S. Department of Commerce because traditional sizes no longer reflected the size and shape of the average consumer.
