A review of 40 studies on breast aesthetics found no single set of measurements that defines an ideal breast. Perceptions of attractiveness depend on factors including a person’s overall proportions, symmetry and cultural background, according to research published in the Aesthetic Surgery Journal.

The review, led by Pegah Damavandi, Zhen Yu Wong and Ryan Faderani, examined studies published between 2010 and 2024. The team set out to map how scientific research measures breast attractiveness and to develop a shared vocabulary for conversations between patients and surgeons.

The studies generally suggested that people assess breasts in relation to the rest of the body, including the torso and shoulder width, rather than judging them by isolated measurements. Symmetry was commonly preferred, while pronounced asymmetry and extreme cleavage tended to receive lower ratings. The findings also challenge fixed rules, such as a specific distance between the base of the neck and the nipple, as a universal guide to aesthetic planning.

Preferences for shape and volume were not consistent across groups. Many studies reported a preference for greater fullness in the lower breast and a flatter upper portion, while some Asian populations favored more fullness in the upper breast. In some research, firmness and contour appeared more influential than overall volume. Respondents also generally favored a centrally positioned nipple and a smaller areola relative to the breast.

Cultural background affected preferences, and the review found that the available research is heavily weighted toward Western and English-speaking populations. Few studies included African or Middle Eastern groups, so the authors caution against treating recurring preferences as global standards. Surgeons’ own aesthetic judgments also varied with their geographic and cultural backgrounds.

The authors say the findings can help guide shared decisions, but not serve as rigid rules. Terms such as “natural,” “lifted” or “full” can mean different things to different patients; discussing them in relation to anatomical features may help clarify goals and what surgery can achieve.

The review also notes limitations in the evidence. Many studies used two-dimensional images, online surveys and convenience samples, which may not reflect how people perceive bodies in real life. The authors call for more three-dimensional research, greater cultural diversity in study populations, and long-term follow-up of patients’ experiences after surgery.
