Best Answer: A tethered hot air balloon flight will typically be between 50-75 feet. It's high enough for the passengers to get a feel for the height and manageable enough for rope length. I have heard of some gas ride balloons that are on a winch go higher. To tell you the truth, I can't recall the max height for tethering. It wouldn't be different than for gas balloons.
A cubic foot of air weighs roughly 28 grams (about an ounce). If you heat that air by 100 degrees F, it weighs about 7 grams less. Therefore, each cubic foot of air contained in a hot air balloon can lift about 7 grams. That's not much, and this is why hot air balloons are so huge -- to lift 1,000 pounds, you need about 65,000 cubic feet of hot air. In the next section, we'll look at the different components of hot air balloons to find out how they heat the air. Print.
