This paper describes different methods for particle characterization, specifically size and shape, from a technical perspective. It emphasizes on analytical proce-dures in the laboratory, practical challenges and data processing. The content is based on hands-on experience with soil and sediment materials and provides the-oretical background information, examples of relevant computations, descriptions of hardware and discussions of using different settings. It is intended to be used as a handbook and may be useful as a guide when designing a local procedure for particle size and shape methods.
