Hourglass and pear share their most visible trait, a clearly defined waist, which is why so many people cannot decide between them. The waist will not settle it. What separates them is balance: an hourglass has bust and hips of about the same size, while a pear’s hips clearly outweigh the bust. Divide your bust by your hips, check your shoulders in a mirror, and you have your answer.
The Body Shape Calculator does both in one step and shows the score for each shape, so you can see how close the call is.
What they share
Look at the calculator’s reference values side by side:
| Bust ÷ hips | Waist ÷ hips | |
|---|---|---|
| Hourglass | 1.00 (spread 0.05) | 0.70 (spread 0.07) |
| Pear | 0.88 (spread 0.07) | 0.74 (spread 0.08) |
The waist ratios differ by only 0.04, well inside either spread. Both shapes have a waist that curves in clearly from the hips. If you have been staring at your waist trying to decide, that is why it has not helped.
The one number that differs
The first column carries the difference. An hourglass bust is roughly equal to the hips; a pear bust is about 88 percent of the hips. On a 40-inch hip, that is the difference between a 40-inch bust and a 35-inch one.
Measure bust and hips as the measuring guide describes, in a bra that neither flattens nor lifts, and divide. A result near 1.00 reads hourglass; near 0.88 reads pear. The calculator has no single cut-off between them. It scores your ratio against both reference points, so in the low-to-mid 0.90s both shapes score well and the waist and shoulders tip the balance.
The shoulder check
Stand in front of a mirror in close-fitting clothes and compare the outer edge of your shoulders with the outer edge of your hips. This matters because a tape around the bust measures the chest, not the frame. Two people with the same bust can have very different shoulders, and broad shoulders over full hips look balanced the way an hourglass does.
The calculator applies your answer only to pear and inverted triangle. Narrower shoulders raise the pear score by a fifth; wider shoulders lower it by a fifth. Hourglass is unaffected, so in a close call the shoulder answer often decides.
Worked examples
All measurements in inches, with the calculator’s top two scores:
| Bust / waist / hips | Bust ÷ hips | Waist ÷ hips | Shoulders | Result |
|---|---|---|---|---|
| 36 / 26 / 36 | 1.00 | 0.72 | same | Hourglass 98%, pear 60% |
| 37 / 27 / 39 | 0.95 | 0.69 | same | Hourglass 79%, pear 73% |
| 36 / 26 / 38 | 0.95 | 0.68 | same | Hourglass 77%, pear 71% |
| 36 / 26 / 38 | 0.95 | 0.68 | narrower | Pear 85%, hourglass 77% |
| 36 / 27 / 39 | 0.92 | 0.69 | same | Pear 83%, hourglass 65% |
| 34 / 27 / 38 | 0.89 | 0.71 | same | Pear 96%, hourglass 55% |
The third and fourth rows are the same body. With hips two inches larger than the bust, the tape alone leans hourglass by six points; narrower shoulders turn it into a clear pear.
When the tape says “almost”, the shoulders decide.
Bottom hourglass: if you are in between
If your ratio lands between the two reference points and your waist is well defined, you match what apparel fitting research calls a bottom hourglass: hips somewhat larger than the bust, waist clearly smaller than both. The FFIT system, built from body scans for pattern grading, lists it as its own shape between hourglass and pear.
You do not need a ninth category to dress it. Take the waist rule from the hourglass and the hem rule from the pear:
- From the hourglass: give every garment a waist, with a seam, a wrap, a tuck or a belt.
- From the pear: keep hems, pockets and horizontal details away from the widest point of the hips, and let skirts and trousers fall straight or flare from there.
What changes in practice
For a true hourglass, the work is mostly at the waist: wrap dresses, belted coats, fitted jackets, and nothing boxy from bust to hip. The full guide is the hourglass body shape page.
For a pear, the waist matters too, but the bigger lever is the top half: structured shoulders, wider necklines and color or detail above the waist, with a cleaner line below. The pear body shape page covers it item by item, and the jeans and dresses guides go further.
Still unsure? Try both sets of advice on clothes you already own. Whichever fits better is the more useful label, and for the other three shapes, start from what body shape am I.
