The present disclosure generally relates to the field of body measurements, and in particular to methods and devices for determining body measurements of an individual in order to e.g. remotely trying out clothes. According to a first aspect, the disclosure relates to a collapsible wall device (1) designed to enable determination of body measurements of an individual positioned on the collapsible wall device. According to a second aspect, the disclosure relates to a computer implemented method for determining body measurements of an individual. The method comprises obtaining (S1) at least two images of the individual and analyzing (S2) a predetermined pattern pictured in the obtained images to detect parts of the images that comprise the body of the individual and to determine reference points of the pre-determ ined pattern. The computer implemented method further comprises constructing (S3) a model of the body of the individual and determining (S4) the body measurements based on the constructed model, the detected body parts and the determined reference points.
