An extension indicator is provided for determining a predetermined extension applied to an extensibly deformable article such as medical bandage used in compression therapy. The indicator includes first (420) and second (430) co-operating members, each adapted to be secured to an extensibly deformable article (440). One of the members is more extensible than the other and each member (420, 430) bears visual indicia (450, 460, 470) which upon extension of the more extensible member, are adapted to align with each other to indicate a predetermined extension of the more extensible member.
