Body Type Chart

The five everyday families, the nine FFIT shapes inside them, and the measurement pattern that separates one from the next. The figures are original diagrams, not photographs.

Hourglass Hourglass · Top hourglass · Bottom hourglass Bust and hips close, waist clearly smaller. 8.4%

2003 SizeUSA sample of 6,318 US women: rectangle 46.1%, spoon 20.9%, inverted triangle 13.8%, hourglass 8.4%, other 10.7%. One US sample from 2003, not a global average.

The five family plates

The family figure is a diagram of the overall line. The sub-shape differences are often at the waist or the high hip, which is why the table above and the individual plates go into more detail than a single silhouette can.

What the nine shapes are

ShapeFamilyWhat separates it
Hourglass Hourglass Bust and hips within 1 inch; waist defined on both sides.
Top hourglass Hourglass Bust leads the hips by 1–10 inches; waist still defined.
Bottom hourglass Hourglass Hips lead the bust by 3.6–10 inches; high hip below 1.193 × waist.
Triangle Pear Hips at least 3.6 inches larger than the bust; waist drop under 9 inches.
Spoon Pear Hips more than 2 inches larger; waist at least 7 inches smaller than hips; high hip flares at 1.193 × waist or more.
Rectangle Rectangle Bust and hips within 3.6 inches; waist within 9 inches of bust and 10 of hips.
Inverted Triangle Inverted Triangle Bust at least 3.6 inches larger than hips; waist drop under 9 inches.
Oval Apple Waist larger than hips, not larger than bust.
Diamond Apple Waist larger than both bust and hips.

The mix-ups that matter

  • Pear vs spoon vs triangle. The high hip is the deciding measurement. Without it, “pear family” is the honest label.
  • Hourglass vs top hourglass. A bust that leads the hips by 1–10 inches is a top hourglass; a bust and hip within about an inch is a pure hourglass.
  • Inverted triangle vs top hourglass. Both have a bust lead. The waist drop decides: at least 9 inches below the bust is top hourglass; less is inverted triangle.
  • Apple vs rectangle. Apple has a waist close to or larger than the hips; rectangle keeps the waist between the bust and hips.

Chart questions

Should I use the five families or the nine FFIT shapes?

Use the five families to navigate and the nine shapes when a fit decision depends on the difference. For example, “pear” is enough for a general style direction; spoon versus triangle matters when you are choosing a high-hip seam or a trouser rise.

Why is there no percentage for some shapes?

The 2003 summary reports rectangle, spoon, inverted triangle and hourglass separately, with 10.7% as “other”. It does not break out top hourglass, bottom hourglass, triangle, oval or diamond. The chart leaves those blank rather than inventing a number.

Can a body be between two shapes?

Yes. The thresholds are measurement boundaries, not natural kinds. A body near a boundary can meet the conditions for more than one shape depending on 1 cm of tape placement. Treat a borderline result as a range.
