They are adjustable: 4’x6’ up to 10’x10’
The legs telescope to provide greater stability with wind.
With on prop you could do:
Year 1 - All 10x10
Year 2 - tall and skinny 4’x10’
Year 3 - eclectic, all different sizes.
Year 4 - a solid wall backdrop (Vero Beach built a 10x80 wall that looked amazing! Unless you were on the visitor side)
If 10x10 isn’t big enough, there is the Media Monster - adjusts to 14x14
Or you can add spinners.
Or you can add flip panels
Or you can change out the corner pieces an make one side 10’high, the other 6’ high of you are tired of squares and rectangles.
And, if you are anywhere near DFW, you can pick them up and save the freight.
