Two calculators every tortoise keeper needs

Find the right table size for your tortoise and check, week by week, whether its weight loss in hibernation is safe.

Table size calculator

What size tortoise table?

Measure the top shell in a straight line from front to back (not over the curve). Most keepers use 10 times the shell length for the table's length.

    Hibernation weight check

    Is the weight loss safe?

    A healthy hibernating tortoise loses about 1% of its starting weight a month. Weigh weekly on the same kitchen scales, at the same time of day.
