Just want to find out which is the correct way to measure your tarantula and how do you guys measure them? I measure leg span but across the body. Like in the second photo.

I also measure across the body.

I go with the second picture, but overseas many go by body length, which would be measured according to the third picture.

I would have thought that the body measurement is more accurate than to include the legs. what is considered a normal standing position for a spider? this is probably a noob question, but how do you measure accurately?

Legspan is probably more accurate that body length, as the latter depends quite a bit on the condition of the T' in question.

When measuring the legspan, the T' should sit in an outstretched but relaxed position, not artificially flattened out.

i would also say pic number 2.

excuse me if i sound stupid but why measure diagonally across? doesnt make sense to me..

Suzi,

I go with the second pic.

That appears to be the most widely accepted means of measurement.
