Age does not come into the jackson ratio only the measurements

Ah, found it under care sheets (originally found it through 'search' )but still haven't fund the one for bigger torts

Caledonia,

Here's a link to the Jackson ratio for larger tortoises. Also contains a method for converting length and weight into a usable formula to judge condition

Thanks. The calculation method appears to be far more precise but it's amazing just how much difference just 2mm or 2 grammes can make to whether the tort is under weight or overweight

Yep. You need to ensure that if using the calculation you do not round the Shell length up or down to the nearest Centimetre. Always use 6.1, 6.1 etc.

It is only a guide though, not a definitive.

You measure the SCL, and compare it to the graph to see if your tortoise is around the correct weight for hibernation.

Maybe it's the SCL she means. I hadn't a clue what SCL stood for to begin with so other newcomers may have the same problem
