Hi team - just a quickie, this is my 1st season for hibernating, my 2 hermans (Thb) are both approx 2.75inch scl, and weigh 73g and 81g......

Looking at the jacksons ratio chart it would seem they are on low/underwieght side, my question is, should i re-weigh them in another month to 6 weeks or so, or do you think i am better kepping them up for this winter?

They are both very active and seem spritely with no signs of any ill health, but would hate to hibernate them if they are not up to the desired weight....

All input welcomed

You need grams and millimeters to measure on the Jackson Ratio, and its not set in stone so how far below does your tortoise come?
Sorry I cant convert from inchs to mm.

as for the jackson chart they are just a tad under the 'low' line, but someone else gave me another method to look at which i will look into shortly
