Frequently asked
JYRO lists the Petra in 55–89 square feet.
In JYRO's words: Experienced competitive canopy pilots with thousands of jumps on small, highly loaded crossbraced canopies (competition-specific).
Wing loading = exit weight in pounds (you plus all your gear) divided by the canopy size in square feet. The manufacturer's chart then shows which category that loading falls in. It is information, not approval to fly a size — decide with your canopy coach.
