What is the Grow a Garden Pet Weight Calculator?

This calculator solves three big problems traders face:
- 📏 Class Prediction — Know if your pet will become Huge, Titanic, or Godly before maxing it
- 💰 Trade Value Check — Heavier pets are worth more, so weight = profit
- ⚡ Ability Power — Pet abilities scale with weight, especially XP boosters and growth speed
How the Pet Weight Calculator Works

The tool uses the official formula to project weights across all ages with 95% accuracy.

Pet Weight Calculation Formula
The Grow a Garden pet weight grows linearly with age. The official formula is straightforward:
Example Calculation:
- Hatch Weight: 1.5 kg (your pet's starting weight)
- Current Age: 50
- Growth Multiplier: 1.0 (default for most pets)
- Result: 1.5 × 50 × 1.0 = 75 kg projection (capped at class max)
Why Hatch Weight Matters Most
Your pet's hatch weight is set when it's born and never changes. A pet hatching at 2kg will always be heavier than one hatching at 1kg, regardless of age. This is why egg hatching matters so much for trading.
Pet Weight Trading Guide for Beginners
Ask the seller for the pet's age 1 weight. This proves it's a real Huge/Titanic at hatch, not boosted later.
Use the calculator to verify the pet's class. Sellers often inflate value claims for low-class pets.
If a pet's current weight doesn't match its age, it's likely a scam. The calculator catches this instantly.
Save proof of pet stats before trading. This protects you if the seller swaps the pet last second.
