Bond's method [Bond (1960). Acta Cryst. 13 , 814–818] has been commonly used to measure precise lattice constants of single crystals. One source of error is the uncertainty in the beam tilt which is usually fixed and unknown. A method is presented here whereby the beam and crystal tilts can be measured to ±0.5 milliradians (mrad). Data taken on a gadolinium gallium garnet single‐crystal with the beam tilt set at − 6.0, 0 and + 5.0 mrad confirms the analysis of Burke & Tomkeieff [ Acta Cryst. (1968), A 24 , 683–685; J. Appl. Cryst . (1969), 2 , 247–248] and the separate analysis of Gruber & Black [ J. Appl. Cryst. (1970), 3 , 354–357].
