Rectangle Body Shape
Bust, waist, and hips all close in measurement -- a straight line down, with little waist definition.
A rectangle reading means all three core measurements sit within a tight band of each other. It sits on the opposite end of the same spectrum as hourglass -- both have bust and hips close together, split only by how much (or little) the waist drops between them.
How it's calculated
This site calls it rectangle when bust, waist, and hips are all within 9% of the largest of the three.
| Measurement | Worked example |
|---|---|
| Bust | 36" |
| Waist | 34" |
| Hips | 37" |
| Result | Rectangle |
Bust/shoulders, waist, and hips are all within 8.1% of each other (at or under the 9% band) -- little to no waist definition.
Dressing guide
- Create the waist with the garment. Belts, wrap styles, peplum hems, and fit-and-flare cuts add definition a straight silhouette doesn't have on its own.
- Layer for shape. A structured jacket or cropped layer over a straight dress breaks up the vertical line.
- Volume top or bottom, not both. A fuller sleeve with a slim skirt (or the reverse) reads as intentional proportion rather than shapelessness.
- Vertical seaming and princess lines in fitted pieces suggest curve without needing to add bulk.
A training note
Glute and shoulder training that adds size at roughly the same rate keeps a rectangle proportion intact even as absolute measurements grow. Core and oblique-focused fat loss is the more direct lever on the waist number specifically if a more defined waist is the goal -- spot reduction from exercise alone isn't well supported, but overall body composition change will show up here eventually.

Frequently Asked Questions
Is rectangle the same as 'no shape'?
No -- it's a real, common proportion where bust, waist, and hips sit close together. It's the most common read in the men's calculator too, just described there with the same rectangle label.
What if my waist has some definition, just not a lot?
Rectangle requires all three measurements within 9% of each other. A waist with more definition than that but still short of the 25% hourglass threshold lands in a middle zone this site buckets as a softer hourglass -- worth reading the wizard's own reasoning line for your specific numbers.
Can training change a rectangle reading?
Yes, in both directions -- waist-focused work that reduces the waist measurement moves toward hourglass; general strength training that adds evenly to shoulders, waist, and hips tends to keep the spread similar even as all three numbers grow.
