Pet size classes and hatch weight
What each size class means, the hatch weights behind them and how big pets get by age 100.

Size classes
| Class | Hatch weight |
|---|---|
| Small | under 1 kg |
| Normal | 1–1.9 kg |
| Large | 2–2.9 kg |
| Semi Huge | 3–4.9 kg |
| Huge | 5–6.9 kg |
| Semi Titanic | 7–7.9 kg |
| Titanic | 8–8.9 kg |
| Godly | 9–9.9 kg |
| Colossal | 10 kg + |
Hatch weight is set when the egg opens and never changes, so a pet’s class is permanent.
Growth by age
Pets grow by about 1/11 of their hatch weight per age and reach 10× their hatch weight at age 100. A Huge pet hatched at 5 kg will weigh about 50 kg at age 100. Try any number in the pet weight calculator.
Why size matters for trading
Bigger classes are rarer, so Huge and above trade at a premium, and Titanic, Godly and Colossal pets are the top tier. When valuing a pet, check the hatch weight — not just the current weight — because two pets of the same weight can be different classes at different ages.
