To calculate the length/s you require, simply run a tape measure around the entire circumference of the front of your telescope. Alternatively, measure the external diameter of your tube in cm and multiply by 3.14 to get the circumference length.
Note that a heater band longer than needed will work effectively, as it can simply be looped on itself.
