Abstract Wilson's (1972a, b) hypothesis of grain size control of dune spacing is tested using data from linear dunes in the Kalahari dune desert. The results confirm Wasson and Hyde's (1983b) rejection of the universal applicability of the theory, though this does not discount relevance to other dune types. Factors pertaining to the rejection of the grain size theory in the Kalahari are considered. Results also demonstrated that the height and spacing of linear dunes are related, but only when values are grouped for blocks of dunes. The gradient of the h / S relationship differs between dunefields, possibly because sand supply differences have an effect upon dune geometry.
