It is generally not a bad idea to weigh and measure your tortoise(s) on a somewhat regular basis to make sure they are growing and gaining weight. Young tortoises should display steady slow growth. Older tortoises won't show much change, but at the very least they should not be losing weight.

I weigh Timmy and Roz about every 6 months as long as they are eating normally. I weigh rescue torts when I first get them, and then every few weeks after that, to make sure they are thriving. Keep in mind that weight may differ a little depending on whether they just ate or defecated... I usually weigh my torts after a bath, before their meal.

I use a metric kitchen scale. It doesn't have to be a metric scale - although both medical dosage calculations and growth charts are metric, so depending on what your purpose of weighing your torts may be, you might have to do a little conversion math. It's a good idea to take note of the weight every time somehow.

Roz gets weighed upside-down... he's half monkey, and wriggles out otherwise.
The most recent weigh-in was on November 3:
Timmy: 855g (7.3 inches shell length) ~remember, Timmy is female
Roz: 505g (5.5 inches shell length)
Joe: 500g (6 inches shell length)
Mo: 580g (6 inches shell length)
Boo: 475g (5.5 inches shell length) ~ I just got Boo, he's a little on the light side, but still ok.

Roz has definitely packed on some weight since I last weighed him - he was 475g at the beginning of the year. Mo is an old old man, so it isn't surprising that he is so heavy - he is one dense tortoise!

If you are unsure if your tortoise is a good weight, HERE is a good calculator using Jackson's Ratio. All my tortoises are within the healthy range.

In comparison, Norbert (aka Stumpy) weighed only 275g when I first rescued him, and he is the same size as Roz! I'm working on writing his rescue story down right now...
