Determine Sizing of Straight Jeans in the US
To identify (a) an estimate for the number of variables which determine good fitting straight jeans in the US and (b) give the variance in adults body sizes in the United States and an estimate the number of sizes required to fit them.
US Apparel Sizing
In the US, "women’s apparel sizing is
, non-determinate, and differs among factors such as style, age or size classification, and brand. This lack of uniformity presents challenges when discussing and classifying female populations and individuals by clothing size and not by body measurements."
ASTM-I is recognized as a leader in the development and delivery of voluntary consensus standards and provides clothing size standards for females, however, standards are driven by the
in the US. Labels and clothing sizes are governed by individual apparel companies in the US, with
no legal regulation
"The National Health and Nutrition Examination Survey (
) and CDC
data contribute to ASTM-I clothing size suggestions." The American National Standards Institute (ANSI) also coordinates the activities of the
development community in the US.
"Many women’s apparel manufacturers base their current size labeling on one of two resources:

Clothing sizes have become even less reliable over the years as the US population has become more

"The 2004 publication of the SizeUSA national survey claims to be an excellent database for size comparison, but it is
to the public."

The average American woman wears a size

According to Forbes, plus size clothing is based on the dimensions of women between the sizes
0 to 6
million American women are thought to be a size

One study that measured more than

34.9 inches to 37.5
For this hour, we tried identifying as much of the requested information as possible. We were able to find some early insights on US apparel sizing.
We found that most women’s apparel manufacturers base their current size labeling on
tables, however, this is not publicly available but can be
for a fee.
also found that the SizeUSA 2004 survey is another database used for size comparison, but it is also
to the public.
also found that the National Health and Nutrition Examination Survey (
) and CDC
data contribute to ASTM-I clothing size suggestions. A link to their most recent data for US
can be accessed
Based on the information, determining good fitting straight jeans and giving an estimate of the number of sizes of straight style jeans which would be required to fit all body types in the United States appears difficult since women’s apparel sizing in the US appears
In the course of our research, we also came across some information on merchandising classifications in the US clothing industry and insights on what consumers think about clothing fit in the US, which might also be of interest.
