A square canopy covers 64 sq ft, and squares suit square tables and rectangular seating groups better than a round canopy of the same span, which wastes shade at the corners. There is no center pole - the arm hangs the canopy from one side, leaving the space underneath clear. Rim height is 7 ft with the whole umbrella 8 ft tall, and it rotates a full circle to follow the sun. The frame weighs 30 lbs in polyester and metal. Gray fabric suits a modern patio; a weighted base is required.
