I have a male 4 1/2 that weighs 341. And a female thats 4" that weighs 335 (it did say 339 but she peed and pooped while on the scale haha) are these healthy weights? Or is there a chart I can refer too?
SIZE? Help?

Come on guys!!!
yep, that's the one!
Yep, see the link above to the Donohue Formula to compute healthy tortoise weight for a given carapace length.
Looks like a lot of math...
Nah, it's not hard. Here it is in a simpler form:
Minimum weight in grams = SCLcm^3 * 0.191
Just measure the straight carapace length of your tortoise. Take that number cubed and multiply by 0.191. If your tortoise's real weight in grams is at least as big as that number, then he is likely fine. If it is less, then he might be underweight. That's all there is to it.

Yes, that's a normal weight.
MATH???? ARRRRGHGGGGGGGGGGGGGGG ***runs into woods***
Come back, it's OK! It is math for our TORTOISES.
Well I can tell you my female Russian is 7 inch's and about 1000 grams and 7 years old.
tortoise Math is good! :]
My husband is an engineer so he managed the math easily. Our little betty is obese I have reduced her chow. I was so worried about how she was malnourished I made a new problem. Thanks for the info, I had the same question.

Hmmm ... how do you know she is obese from that equation? The Donahue Formula tells you what the minimum weight is for a healthy tortoise, but it doesn't tell you the maximum. In other words, it's not a Tortoise BMI, so how did you figure out your tortoise was overweight?

That equation has both a upper range as well as a lower range for weight. BUT it also tells you that there is a percentage area where the results could be "Healthy".
For instance, WalkingRock scored a 0.786 showing that he is underweight or dehydrated but there is a 15% chance that this IS a healthy weight for him. If her score was 1.33 or higher, her tortoise is obese OR there is a 2.5% chance that this weight is accually healthy for this tort.

Oh, I think I see. Is that from calculating tBMI (tortoise BMI) then, as the Tortoise Library link above explains? I never noticed that part before.
She is 1.2% which he said means she has 15% chance likely to be a healthy weight. She was 20 grams lighter when we last weighed her which he said would have been in the 1.1% category.
I figured I was making her fat because the vet said she probably wont overeat so I have been giving her a little more than we had been originally and she gained 20 grams in two weeks. I figured I am a bad monkey and I am a bit of a spoiler, but I also know I have to keep my animals healthy, sooooooo I adjusted her feeding and will have her exercise a little more so she drops some of her extra weight.
My lab is a chowhound so I have to do the same type of restraint with her too.

That whole thread caught my attintion as soon as it hit! I always thought WR was HUGE... when I found out he was underweight, I started noticing little things that turned out to be sign of dehydration. According to the Math, WalkingRock should be closer to 95lbs than his current weight of 75lbs. After taking action to re-hydrate (daily soaks) all signs of dehydration dissappered but his weight is still under 80lbs, so I'm calling him part of that 15% healthy weight.
