GRADISTAT is extremely versatile. It accepts both standard and non-standard size data, meaning it can handle not only standard phi (φ) intervals but also any custom size breaks you have from your specific measuring equipment.
The software is often maintained in academic repositories or specialized sedimentology pages.
Gradistat V 9.1 is a sophisticated software package designed to analyze and interpret granulometric data. Developed by experts in the field, this software has become a benchmark for particle size analysis, offering a wide range of features and tools to facilitate accurate and efficient data processing. With its user-friendly interface and advanced algorithms, Gradistat V 9.1 has become an indispensable resource for researchers, scientists, and industries worldwide. gradistat v 91 link
: Includes the popular Folk and Ward (1957) graphical methods and the method of moments.
Originally developed by Simon J. Blott and Kenneth Pye, GRADISTAT was designed to automate the calculation of grain size statistics from standard measurement techniques, such as dry/wet sieving and laser granulometry. The program was introduced to the scientific community via a seminal paper in Earth Surface Processes and Landforms in 2001, and has since become a benchmark tool in sedimentary geology.
Due to compatibility challenges with newer versions of Excel, some researchers utilize the
This creates a clear distinction:
Warning: Ensure macros are enabled. Version 91 requires 32-bit Excel or legacy compatibility mode on modern Office (64-bit may need a patch).

Understanding GRADISTAT Version 9.1: The Essential Tool for Sediment Granulometric Analysis
If one encounters a reference to gradistat v 91 without a functioning link, several steps are advisable. First, check Internet archives (e.g., Wayback Machine) or academic social networks (ResearchGate, LinkedIn) for the author. Second, search for similar tool names: "Gradistat" might be a misspelling of "GradStats" (a Python package for gradient statistics) or "Gradistat" as a legacy MS-DOS program for sedimentology (unrelated to gradients). Third, contact the citing paper’s corresponding author. Often, software links decay but authors maintain local copies. Finally, consider that "v 91" might be a typo for "v 0.9.1" — a common semantic versioning pattern.
