Weight

[Richmond2]

Hat is the average weight for a 1 year old hermann tortoise

 

[JoesMum]

It varies. Is your tortoise male or female and how long is it. (Measure the plastron (under shell) from end to end)

 

[Richmond2]

4-5cm

How much should he weigh 1year old 4-5cm plasteron

I'd love to get an answer to this question too as we have a 5cm Hermaan's who will be 1 year old in one month.

A good estimator for weight is the Donoghue Ratio-

Shell length in centimeters, to the third power, times 0.191 gives you the target MINIMUM weight in grams (SCLcm^3 x 0.191 = WTgr)

So... 4cm should weigh about 12.2 grams, and 5cm should be 23.9gr. You can see that accurate measurements make a big difference.

To get an accurate SCL (straight line carapace length), push the tortoise up against a block or wall so the shell hits the block. Make a mark on the ground at the back of the shell. Measure between the marks. (You can also use calipers and other tools to get accurate readings. Measuring the plastron does not always give the same readings as the above methods and does not work as well for the Donoghue Ratio.

Thank you for this formula, Madkins007!

Is there by chance a formula for determining the age of a tortoise through measurements?
