The variety of window shapes that have been designed to create architectural features has lead to the development of blinds that maintain these effects. With the appropriate window blind system triangular, rhombus and sloping windows can all be covered as well as shaped roof lights that are found in conservatories, roof systems and atriums. In addition arches, circles and other unusual shapes may be covered.

For roof light applications, pleated blinds, woven wood blinds and non-retractable blinds will provide a solution to most shapes whilst roller blinds with suitable reinforcement of the fabric can be made for triangular shapes, blinds fitted to these applications may feature a framing system. For vertical windows, mini venetian blinds and pleated blinds can be made for almost any style and vertical blinds have standard designs for arched and sloping windows.
