We developed a method to calculate the statistical distribution of a scaling factor from soil‐water retention curves. The method consists of measuring the particle‐size distribution by laser scattering, computing soil water retention curves using the Arya and Paris model, and calculating a scale factor for each function. The method was tested by comparing measured and predicted soil‐water retention curves. The advantage of this method is in its simplicity and ease of use. The applicability of the method to a given soil texture depends on the verification of the calculated soil‐water retention functions.
