Sizing Chart

Estimated Tiny through Colossal weight bands for each dinosaur, how the chart works, and all 103 species weight ranges.

Size classes

Dinosaurs can hatch as Tiny, Small, Normal, Big, Giant, or Colossal. Colossal is the highest size class.

Example: Trilobite has a listed weight range of 0.4–4.5 kg.

Estimated Trilobite size ranges
Size labelWeight range (kg)
Tiny0.4–0.81
Small0.81–1.63
Normal1.63–2.86
Big2.86–3.885
Giant3.885–4.377
Colossal4.377–4.5

Reading weight ranges

These estimated bands place the size thresholds along each dinosaur?s listed minimum-to-maximum weight range. For example, a 100?200 kg range puts the 10% boundary at 110 kg. The game?s exact weight-to-size mapping is unconfirmed.

At a shared boundary, use the larger size class. Colossal includes the maximum listed weight.

Displayed weight changes as a dinosaur grows. Compare dinosaurs at the same growth stage.

The lower number is the minimum listed weight and the upper number is the maximum listed weight for that species. They are not the weights of a Newborn and an Elder. Size class and growth stage describe different things.
