This study analyzed body measurements of women aged 70+ from the 8th Size Korea data to provide information essential for reducing user inconveniences associated with four-wheeled walkers for elderly women by comparing various handgrip heights from previous studies. Even within the same height group, handgrip heights among women aged 70+ were significantly lower than among women in their 50s and 60s. Handgrip heights calculated based on wrist height and elbow height were significantly lower than those calculated based on height. To improve consumer awareness and industry applicability, a comparison using height index values revealed that handgrip height based on wrist height was 1% lower (47%) than the height for the elderly in general (48%), and handgrip height based on elbow height was 0.5–0.7% lower than the height for adults (52%). In the balance-related group, where bow legs typically reduce waist height, handgrip heights based on wrist and elbow heights were significantly lower (0.5–1%) than those for elderly women in general. To ensure safety and mobility, the dimensions of four-wheeled walkers should reflect the physical dimensions of people aged 70+ as the target audience. In particular, sturdy yet easily adjustable handgrips should be used to allow handgrip heights to be modified safely and easily to meet specific balance challenges.
