Discussion in 'Ballroom Dance' started by rinachick, Oct 15, 2007. So, I've been reading that the standard ballroom floor size is 60' X 40', but when my partner and I actually measured that out on a floor, it seemed way bigger than what I've encountered at hotel ballrooms and such.
Refer to the example dance floor on the right. 1  Measure width and length of your floor. 2  In the example, the width is 12ft (A) and the length is 18ft (B). 3  To calculate the total square footage, use the formula AxB = total sq ft.4  In the example, 12ft x 18ft = 216 square feet.efer to the example dance floor on the right. 1  Measure width and length of your floor. 2  In the example, the width is 12ft (A) and the length is 18ft (B). 3  To calculate the total square footage, use the formula AxB = total sq ft. 4  In the example, 12ft x 18ft = 216 square feet.
