The purpose of this study was to investigate if the laser device has inter-rater reliability, how the laser-device measures supine height in comparison to standard methods, and if the laser device will be consistent in measuring human height shorter, as seen in previous studies. Two investigators measured a total of 80 adults independently. Measurements included knee height, arm span, demi span, supine height by laser, standing height by laser and standing height by stadiometer. There was a strong inter-rater reliability for the laser height measurement: excluding one outlier r=0.998. Supine height measures done with a laser were strongly correlated with arm span, but mean values were closest between supine height and knee height (171.3cm and 171.2cm). The laser measured standing height 0.5cm shorter, on average, than the stadiometer. It is concluded that the laser device is a reliable, validated tool to measure human height, standing or supine.
