Bikini Calculator

Your body shape is determined by comparing your bust, waist, high hip, and hip measurements. Common shapes include hourglass, pear (bottom hourglass), inverted triangle, rectangle, and spoon. This calculator analyzes those four measurements and classifies your shape automatically.

Use a soft measuring tape held snugly but not tight. Measure your bust at the fullest part of your chest, your waist at the narrowest point of your torso, your high hip about 4 inches below the waist around the upper hip bone, and your hip at the fullest part of your hips and buttocks. Stand straight and breathe normally while measuring.

Pear shapes have hips wider than the bust. To create visual balance, opt for a more eye-catching or padded bikini top to draw attention upward, and choose dark, solid-colored bottoms in a classic brief or boyshort style. High-waisted bottoms are also a popular flattering choice for this shape.

High-waist bikini bottoms are especially flattering on pear, rectangle, and spoon body shapes. They help define the waist, provide extra coverage, and balance proportions between the upper and lower body. They're a great retro-inspired option that also offers a bit more support.

Petite frames benefit from bikinis with minimal coverage on the bottom (like Brazilian cuts or string styles) to elongate the legs. Tops with underwire or padding can add the illusion of a fuller bust. Avoid overly large prints or wide horizontal stripes, which can visually shorten the frame.

The waist-to-hip ratio (WHR) is calculated by dividing your waist measurement by your hip measurement. It's a useful indicator of body proportions. A WHR below 0.8 is generally associated with a more curvaceous figure, while a higher ratio suggests a straighter or more cylindrical silhouette — both of which influence which bikini styles will be most flattering.

An hourglass figure has roughly equal bust and hip measurements with a noticeably narrower waist. Almost any bikini style works well, but classic triangle tops and cheeky or high-cut bottoms highlight your natural curves beautifully. Wrap-style tops and tie-side bottoms also accentuate the waist.

For a larger bust, look for underwire bikini tops, wide-set straps, and full-coverage cups for extra support and comfort. Halter-neck styles distribute weight better, and tops with adjustable bands ensure a secure fit. Avoid triangle tops with minimal coverage, as they may not provide enough support.
