How tall should you buy aerial silks?

The height of aerial silks you should buy typically depends on the space where you'll be using them and your own height. A general guideline is to choose silks that are at least twice the height of the rigging point, plus an additional 10-15 feet for safety and tying knots. For personal use, if you’re around 5 to 6 feet tall, 30 to 40 feet of silk is usually sufficient. Always consider the specific environment and your skill level when selecting the length.
