I go by weight, too. As Bill said there is too much variation in thickness &
maybe even density. In addition, for me measuring thickness is more of an
approximation than an exact measurement. I find it very frustrating to try to
make a specific change to a motor. For example, I would like my next no-cal
motor to be 17" loop and weigh 0.98 grams. I will be lucky to be +/- 5% of that
target weight.

I know - I'm still stuck with wanting to know the width also. But the truth
is that the thickness of Tan 2 varies enough that the weight per inch is a
more reliable unit of measure. My last time out to fly I hurriedly cut some
2/99 for my SO model. I cut it smaller than what I had used previously but the
final 1.5g motor was shorter than the previous motor due to the rubber being
thicker
