Abstract Geometrical element of the system AR Lacertae have been obtained and its colour has has been discussed.The absolute dimensions have been obtained on the basis of the spectroscopic elements given by Sanford (1951).The primary component lies fairly close to the Main Sequence on the log m-log R plot and the secondary falls away from the Main Sequence.The values of the Roche constants indicate that AR Lacertae is a detached system.
