High-altitude balloons typically reach the stratosphere, often around 60,000 to 120,000 feet depending on balloon size, payload weight, gas volume, and weather conditions. Some specialized missions can go higher, but performance is always tied to lift calculations, payload design, and flight objectives. For research missions, altitude targets should be matched to instrumentation, tracking, and recovery planning from the start.
