There are a lot of women’s body shapes or types infographics around, but they’re generally vague as to what body shape fits into what classifications. If you’re on the borderline, it’s hard to tell. This one below that I found has not only specific measurements for what qualifies as certain body types, but also a distribution of women in society that carry that body. The latter should be taken with caution as obesity is a lot worse now than it was back in 2003 when the sample of 6318 women were scanned. The lack of a “round” or “diamond” classification where the waist is the biggest of the bust, waist and hip measurements should drive that point home pretty clearly. Women in different cultures may also have different distributions of these shapes. However, you can still get an idea of what share of the American (or similar) female population has what body type shown, and which ones might be more or less common now than back in 2003.
In sewing, often only 3 measurements are required on patterns to determine a size to follow: bust/chest, waist and hips. That’s about as impractical as anything I’ve ever seen considering people are all kinds of height and shapes outside of those measurements. The vast majority of people don’t even fit the standard sizes made!
