A portable screen assembly includes first and second frames extending parallel to each other, a spring-biased roll rotatably mounted in the first frame, and a screen bonded at its one end to the second frame and wound around the spring-biased roll. An extender is provided for biasing the first and second frames away from each other to impart a predetermined tension to the screen. During use of the portable screen assembly, the first and second frames are supported generally vertically by a plurality of support legs.
