Abstract
One believes that lumbar intervertebral disc size and volume vary according to body size. A literature search disclosed no reports supporting this hypothesis.

There was a significant correlation with height, a moderate correlation with BSA, no correlation with weight, and a trend suggesting a possible correlation with age.
