Proportions define a sex doll’s character and the aesthetic you want to convey. Start by researching the look you’re aiming for—whether athletic, voluptuous, or slender—and translate that into measurements such as torso length, limb proportions, and shoulder width. Consider the overall silhouette: a longer torso with shorter legs yields a different presence than a compact frame with elongated limbs. The neck, head size, and jawline also shape perceived personality; a larger head relative to the body can create a more anime-inspired or doll-like look, while balanced proportions tend toward realism.

Practical use also matters. If the doll is intended for frequent posing or action-based photos, prioritize joint range and limb strength in the design. For display or portrait-focused sessions, head-to-torso proportions and neck length can dramatically impact camera angles and lighting. Keep in mind that different materials stretch and age differently, so discuss tolerances with the maker to ensure the proportions hold over time.

Collaborate with the maker to see a 3D mockup or turntable visualization before production. This helps you validate the balance between bust, waist, and hip measurements, as well as the length of limbs and neck. Ultimately, aim for proportions that compliment your intended aesthetic while maintaining comfort, durability, and ease of maintenance.
