Disclosed is a method of selecting a pillow for a user (10) by measuring a deltoid temporal distance to improve the process for a consumer to purchase a pillow. The method measures a linear dimension of a pillow for selecting the thickness of a pillow so an appropriate level of support is provided to a user to ensure correct alignment of the body. The method comprises the steps of locating the user (10) with a shoulder (14) thereof adjacent an upright flat rigid surface (16), such as a wall. The user (10) is oriented transverse to the flat rigid surface (16). A spacing is measured between the flat rigid surface (16) and a proximate side of the user&rsquos head (18). A pillow is selected from a group of pillows based on the measured spacing.
