Globally, the popularity of certain sizes of real sex dolls hinges on cultural preferences, practicality, and personal comfort. The most common sizes range from compact models around 140 cm (4.6 feet) to full-sized adult dolls approximately 160-170 cm (5.3-5.6 feet). Smaller dolls are favored for their portability, ease of storage, and affordability, making them popular in urban environments with limited space.
Medium-sized dolls offer a balance between realism and convenience, catering to consumers seeking a lifelike experience without the bulk of larger models. Full-sized dolls are preferred by those desiring maximum realism and presence, often used for companionship or intimacy.
In some regions, unconventional sizes—such as miniature or oversized dolls—are gaining popularity for niche markets or collector communities. Overall, the trend favors customizable options, allowing consumers to choose sizes that best suit their needs, preferences, and living situations.
