Choosing the correct tipi diameters is essential to prepare for teh trip. The tipi diameter will determine how much space you has for your sleeping pad, your gear, and your stove. If the tipi is too small for your sleeping pads, you will not have enough room for your sleeping pads and your gear.
Another essential issue to consider is that tipi have walls that slope inward. Thus, the floor area will be less than the total tipi footprint. Additionally, there is a tipi center pole that will take up space, as will the tipi liner or stove.
How to Choose the Right Tipi Size
Because the tipi liner and stove takes up space within the tipi, the tipi diameter must account for this lost space for the floor of the tipi. The tipi diameter calculator ask for specific measurements to calculate the tipi diameter. The calculator will ask for the width and length of the sleeping pad that each person will use.
The width and length of the sleeping pad will determine the amount of space that each person need within the tipi. The tipi diameter will also ask for the width of the sleeping pad to account for the percentage of the wall loss of the tipi. Tipi walls slope inward, thus taking space from where sleeping pads can go.
The tipi diameter will also ask for the liner gap. A tipi liner take up space within the tipi and reduces the radius of the tipi. The tipi diameter will also ask for stove clearance and pole space.
These two items will also take up space in the tipi that sleeping pads cannot use. The tipi diameter calculator offer more than the tipi diameter. It will calculate the total area of the floor of the tipi, the sleeping area that the participants in the trip can use, and the estimated height of the center of the tipi.
The usable sleeping area will tell you if there is enough space for each sleeping person. Additionally, if the tipi have an estimated center height and pole length, you can determine if you can stand up inside the tipi. It might be possible to sleep in the tipi but not feel comfortabley standing up.
Many people makes mistakes when they calculate the tipi diameter. Many people treat the tipi like a square room. They do not account for the sloped walls of the tipi taking up space from sleeping pads.
Additionally, many people do not account for the space that gear will take up. Their sleeping pads will end up on top of their gear. Thus, it is essential that the tipi diameter accounts for gear spaces.
Depending on the purpose of the tipi, the calculated tipi diameter might need to be adjusted. For instance, if a solo hunter will use the tipi as a hunting tipi, a smaller diameter might be calculate. However, if a family will use the tipi, a larger tipi might be needed for the stove and gear.
Additionally, the height ratio of the tipi can be considered. A taller tipi will provide more headroom for those standing near the walls of the tipi. However, a taller tipi require more poles and canvas than a low tipi.
Thus, it might not be as easilyly transported as a low tipi. Once you have calculated the tipi diameter, it is essential to use the reference tables to confirm the calculation. The reference tables will include area, center height, and sleeping load for various sizes of tipis.
These tables will allow you to compare your calculated tipi diameter to others out there. Measure all item that take up space on the floor of the tipi. Add up all clearances that are fixed and cannot be accounted for by the sleeping individuals.
Finally, use the tipi calculator to ensure that your tipi diameter accounts for the sloped tipi walls and the center pole.
