Re: [ojf1982] Determining weight for w/l
A good rule of thumb, by which you cannot go too wrong, is the following table where are reported the
naked weight of jumper and "proper" canopy size:
60 kg - 132 lb: 220-225 ft²
70 kg - 154 lb: 240-245 ft²
80 kg - 176 lb: 260-265 ft²
90 kg - 198 lb: 280-285 ft²
100 kg - 220 lb: 310-320 ft²
Any jumper whose weight falls in between the above weight, is free to choose either the smaller or the bigger canopy size, considering that the bigger canopy you have above your head, the slower (and the better

) you will fly.
Of course, case by case, jumper by jumper, put in the choice process issues like: experience, usual location of sites jumped, usual condition of landing of sites jumped, body fitness, whatever, can make switch the decision from a certain canopy size to the preceeding or following size.
