is a widely used Microsoft Excel-based program designed for the rapid analysis of grain size statistics from unconsolidated sediments. It was originally developed by Simon J. Blott and Kenneth Pye. Core Functionality

The software automates the calculation of essential sedimentological parameters from raw data obtained through techniques like sieving or laser granulometry: Statistical Measures

: It calculates mean, mode, sorting (standard deviation), skewness, and kurtosis. Calculation Methods : Statistics are computed using both the Method of Moments (arithmetic and geometric) and the Folk and Ward (1957) graphical methods. Data Scales gradistat v 91 link

: Supports results in both metric (micrometers/millimeters) and logarithmic (phi) units. Graphical Outputs

: Generates frequency plots, cumulative distribution curves, and ternary diagrams for sediment classification. Versions & Compatibility Version 8.0

: Released in 2010, this version was optimized for Microsoft Excel up to the 2010 version. Version 9.1

: While "v9.1" is often cited in academic datasets and research papers for grain size analysis, official legacy downloads typically point back to the Kenneth Pye Associates Ltd (KPAL) software page GRADISTAT-PRO

: A fully revised version with expanded functionality has been noted as under development by the original authors. Alternative Tools

Due to compatibility challenges with newer versions of Excel, some researchers utilize the

package in R, which was built as an evolution of the GRADISTAT macro. It provides similar descriptive statistics and can be accessed via a web-based interface for those unfamiliar with R coding.

GRADISTAT is a widely used Microsoft Excel-based program designed for the rapid analysis of grain size statistics

in unconsolidated sediments. Developed by Simon J. Blott and Kenneth Pye, it streamlines the complex calculations required to classify sedimentary environments from data collected via sieving, laser granulometry, or other measuring techniques.

While older versions (like 4.0 and 8.0) are historically available through official channels, GRADISTAT version 9.1

is frequently cited in recent scientific research (e.g., studies on North Atlantic Oscillation or floodplain deposits) as the primary tool for calculating grain size parameters. ScienceDirect.com Official Resource: The software is managed by Kenneth Pye Associates Ltd

The program is highly valued for its ability to process approximately 50 samples per hour and provide both tabular and graphical outputs. Michigan Technological University GRADISTAT software - Kenneth Pye Associates Ltd

Because "Gradistat" is not a cloud-based software but rather a protected Excel workbook (typically .xlsm or .xls), there is no public "browser link" to access it directly. It must be downloaded and opened in Microsoft Excel.

Here is a post looking at the details, how to access it, and why it remains a standard in geology and sedimentology.

If you work in sedimentology, soil science, or coastal geomorphology, you have likely heard of GradiStat. For years, this Excel-based add-in has been the quiet workhorse of grain size analysis. Today, we are looking specifically at Version 91—a widely used iteration known for its stability and compatibility. Downloading and Installing Gradistat v 9

Note on the Link: The official distribution for GradiStat has historically moved between university servers (often the University of Brighton’s GeoData Institute). As of this writing, the most reliable way to locate the GradiStat v.91 link is to search academic repositories or the Internet Archive (Wayback Machine) for the original gradistat_eng.xls file. Due to the dynamic nature of academic hosting, I have provided the direct file context and setup instructions below rather than a broken URL.

If you are looking for the download right now, I cannot provide a direct unauthorized download link, but I can direct you to the legitimate sources:

There are two main ways to input data depending on the version you are using.

Official Source: The software is freeware but requires permission from the author for commercial use. It is hosted on the Kenneth Pye Associates Ltd website.

Important Note on "v 91": The standard public versions are usually labeled v8 or v9. If you have a file specifically labeled "v 91," it is likely a specific university modification or a typo for v9.1. Always scan downloaded Excel macros with antivirus software before enabling macros.
