BodyTypeCalculator.ai

BodyTypeCalculator.ai is a fitness tool that finds your body shape from three measurements, privately. A free web calculator that classifies female or male body shape from bust or chest, waist and hip measurements, with ratios, boundary warnings and an optional AI-written explanation.

BodyTypeCalculator.ai is a browser-based tool that sorts a person into a body shape category using three tape measurements: bust or upper body, natural waist, and fullest hips. Female mode returns hourglass, pear, apple, rectangle or inverted triangle. Male mode returns trapezoid, rectangle, oval, triangle or inverted triangle, and lets the user choose shoulder or chest circumference as the upper-body basis. The core result comes from a fixed rule set that runs locally in the browser. The same valid measurements always produce the same base type, and changing a number recalculates it immediately. The report shows the type, the bust-to-waist and waist-to-hips ratios, the nearest neighboring type, and how far the numbers sit from a rule boundary. When a result lands close to that boundary, the page flags it as borderline and suggests measuring again. A live diagram redraws the three widths as the values change, and measurements can be entered in centimeters or inches. An optional AI layer adds a written explanation. A front-facing photo (JPEG, PNG or WebP, up to 5 MB) can be attached, but it only adds context to the text and never alters the measurement-based type. If the user consents, the processed photo and measurements are sent once to Pollinations, the external AI processor, and the site states it keeps no analysis history. Shared links and downloadable PNG result cards contain only the profile, type, rounded ratios, confidence label and a disclaimer, never the photo or raw measurements. The audience is people choosing clothing or looking for general styling reference, without wanting to create an account. Each body type has its own explainer page. The tool is explicit that it is not a health, weight, fitness or attractiveness assessment. Compared with broader fashion apps or virtual fitting tools, it is narrower and more transparent: a deterministic formula with AI as a clearly separated extra.
