s rule. Here we present a guide to accurate measurements of single crystals with dimensions ranging from 200m up to several millimetres using a standard powder diffractometer in Bragg-Brentano geometry. The correction of the error introduced by the sample height and the optimisation of the alignment are discussed in detail. In particular for single crystals with a plate-like habit, the described procedure allows for measurement of the lattice spacings normal to the plates with high accuracy on a timescale of minutes.
