When a custom tent is being designed, the maker generally considers the size closely to determine the right process and layout to use.
The size of the tent will be defined by a number of factors like the total number of people who will be staying inside as well as the age or size of the inhabitants.
The tent will be used for sleeping at night, for housing camping gear as well as for protecting people and things from extreme weather. The tent will be very beneficial for different types of trips.
There are a few more things that should be kept in mind when considering size:
Are you going to use the tent on cycle tours? If so, you have to give it adequate space to cover the bikes well during harsh weather conditions.
The tent might also come with an awning.
The design should consider the awning as well.
Consider the internal height of the tent.
This will show you the total amount of space available as well as the right design that will suit the activity.
Ridged tents will also include sloping roofs.
The entire height might not be fully used.
You can also try other tent types like tunnel tents that have enough height at the center and dome tents that let water runoff from the top to the sides easily.
Custom tents will also feature almost vertical walls and a sloping roof to protect these from the elements. Consider the available options before you get the right design.
