Turtle Nutrition tools: what they help with

These calculators work out what and how much to feed a turtle: daily calories, portion sizes, feeding schedules, water needs and which foods to keep away from it. Diet is the single biggest thing most owners control. Getting portions right prevents obesity and the many problems that come with it in a turtle.

What to know about nutrition and feeding for turtles

A practical tip

Weigh food rather than using a cup or scoop. Measuring by volume is one of the most common reasons pets are overfed.

Other turtle topics

Turtle care rarely sits in one box. You may also find these useful: turtle age tools, turtle behavior tools, turtle breeding tools and turtle cost tools. Or see every turtle tool in one place.

Nutrition tools for other pets

The same kind of tool exists for other species, each using that animal's own reference data: tortoise nutrition, gecko nutrition, bearded dragon nutrition and iguana nutrition.

Frequently asked questions

How much should I feed my turtle?

It depends on body weight, age and activity. The turtle food and calorie calculators give a daily starting amount, which you then adjust based on body condition.

How much should an adult turtle weigh?

A typical adult turtle weighs 500 g to 3 kg, though frame and body condition matter as much as the number.

Which turtle nutrition tool should I use first?

Most people start with the Turtle Feeding Schedule Planner, the most used tool in this group. If your question is more specific, the list above describes what each of the 2 tools does.

How accurate are the results?

They are estimates based on published reference data for turtles, and each tool lists its sources. Individual animals vary, so treat results as a guide and check health decisions with your vet.
