Kroppsdjup

Kroppsdjup, or body depth, is an anthropometric dimension that describes the front-to-back thickness of the human torso or body at a given level. It is measured in the sagittal plane and is used alongside other dimensions such as height, chest circumference and waist circumference to characterize a person’s physique. Different measurement points exist depending on the design purpose, for example thoracic depth at the level of the sternum or nipples, and abdominal or hip depth for other applications.

Measurement methods vary, but the general approach involves a standing or seated person with a relatively straight posture and a calibrated instrument such as an anthropometer or calipers. The resulting value is typically recorded in centimeters or inches. Posture, breathing, and muscle tension can influence the measurement, so standardized procedures are important for consistency.

Applications of kroppsdjup include ergonomics and industrial design, where it informs the depth of seats, backrests, and other enclosures to accommodate the torso. In clothing and garment pattern making, body depth affects the fit of bodices, jackets, and dresses, and may be considered when designing adjustable features. In some medical contexts, related sagittal depth measurements can contribute to assessments of thoracic structure or spinal alignment, though kroppsdjup is more commonly discussed in design and performance contexts than clinical diagnostics.

Variation in kroppsdjup occurs across sex, age, body composition, and ethnicity, with population-specific reference values available in anthropometric databases. Limitations of using a single depth measurement include its inability to capture the full 3D shape of the torso; comprehensive assessments often rely on multiple measurements or 3D body scans.
