To determine the number of rafters needed for a 26-foot yurt, you typically space the rafters evenly around the yurt's circumference. A common spacing is about 3 feet apart, which would suggest needing around 8 to 10 rafters, depending on the exact design and structural requirements. It's best to consult specific yurt construction guidelines for precise measurements and spacing recommendations.
