PDI vs. SPAN: Which Metric Best Represents Particle Size Distribution?

June 13, 2025

In the fields of nanotechnology and materials science, particle size distribution (PSD) is a critical parameter that directly influences the performance and applicability of nanomaterials. Two of the most commonly used indicators to evaluate PSD are the Polydispersity Index (PDI) and the SPAN value. While often used interchangeably, these two metrics differ significantly in how they are calculated and interpreted. Understanding the distinction between PDI and SPAN is essential for accurate particle characterization.
