The recommended space needed for jumping rope is 10 ft front-to-back, 7 ft side-to-side, and a ceiling height that is roughly equal to your rope length.
So if you order size Small, you need at least 8 ft of ceiling height. If you order size Medium, you need at least 8’6” ft of ceiling height. If you order size Large, you need at least 9 ft of ceiling height. And if you order size XL, you need roughly 9’6” of ceiling height.
Please make sure your jumping space is clear and that you do not have anything on your ceiling that would obstruct your jumping (lighting fixtures, ceiling fans, etc.).
