Using GRADISTAT requires standard spreadsheet workflows. Follow these baseline steps to map your data:
Statistics are provided in both metric units (micrometers) and logarithmic phi units .
While version 9.1 is not the absolute latest (with versions 8.0 and later being more compatible with modern Excel), you can obtain version 8.0 or similar from the official source. Many researchers using v9.1 in their work accessed it through this same channel. Exercise caution when using third-party websites for downloads, as they may contain outdated or altered versions. gradistat v 91 free
In sedimentology, geomorphology, and civil engineering, analyzing how particle sizes are distributed is essential for classifying sedimentary environments and understanding soil physics. Calculating these statistics manually across dozens of samples is incredibly laborious. To streamline this, Dr. Simon Blott developed , a highly popular, macro-driven Microsoft Excel workbook designed for rapid grain size analysis.
A revised version with enhanced functionality that has been under development. Where to Access

GRADISTAT is a widely used designed for the rapid analysis of grain size statistics from sediment samples.
GRADISTAT's primary function is to automate the calculation of key sedimentological parameters. It can process data from standard measuring techniques, including sieve analysis and laser granulometry. The software calculates statistics such as: While version 9
: Statistics (mean, mode, sorting, skewness, kurtosis) are calculated arithmetically/geometrically in metric units and logarithmically in phi units.
📍 Gradistat v 9.1 remains the most cost-effective and user-friendly tool for sedimentological analysis. It bridges the gap between manual spreadsheets and expensive proprietary software.
Great news for sedimentologists and geologists! The latest version of the popular grain size analysis spreadsheet, Gradistat, has been updated to version 9.1.
