🐾 Grow a Garden Pet Calculator (KG at Age 500, Size Class & Trade Values)
Dedicated Grow a Garden pet calculator — your pet's kg at age 500 from its current weight and age, size class (Huge, Titanic, Godly), what drives pet trade value, abilities, cooldowns, and the September 2026 pet tier list. For crop Sheckle values, use the Grow a Garden calculator on the homepage.
⚡ New: the pet ability calculator shows any pet's cooldowns, chances and amounts at its weight, at any age up to 500, with pet mutation and toy boosts.
🧮 Pet KG Calculator — Weight at Age 500
Enter your pet's current weight and age from the in-game tooltip. The calculator back-solves its Age-1 (hatch) weight, its size class, and its exact kg at age 500 or any target age.
⚖️ Weight at Target Age
Age-1 weight: 0 kg
How pet weight grows with age
Every age, a pet gains one-eleventh of its Age-1 weight. That gives two formulas:
Weight at any age = Age-1 weight × (Age + 10) ÷ 11Age-1 weight = 11 × current kg ÷ (current age + 10)
So a pet ends up about 46.4× its Age-1 weight at age 500 (510 ÷ 11). A 1.10 kg hatchling reaches 51.0 kg; a 5 kg Huge reaches about 232 kg. Size labels (Huge 5+ kg, Titanic about 7–9 kg, Godly 9+ kg at age 1) are community conventions and sources differ slightly on exact cutoffs. The Pet Mutation Machine needs age 50+, not 500. Sources: the Grow a Garden wiki's Pets and Pet Mutations pages, cross-checked against independent calculators — see how we verify.
💡 Ability-strength and cooldown changes with age are estimates — the game doesn't publish that curve. Crop Sheckle values are on the homepage Grow a Garden calculator; see how pet trade value works below.
💎 How Pet Trade Value Works in Grow a Garden
You can sell a pet to Steven at the Sell Stuff stand, but the game doesn't publish how a pet's sell price is worked out, and what players pay in trades is set by the players. So there's no official pet value. We used to show "token values" here, but those numbers were generated from each pet's rarity, ability strength and weight range, not from real trades. A made-up number isn't a fair basis for a trade, so we removed it.
What actually moves a pet's trade value:
- Species and rarity — limited event pets and Divine/Prismatic pets are scarcer.
- Age-1 (hatch) weight — heavy hatchlings (Huge, Titanic, Godly) are rarer and keep that advantage at every age. Check yours with the Pet KG calculator.
- Age — weight keeps growing to age 500 (about 46× the Age-1 weight), and older pets have stronger abilities.
- Pet mutation — the Mutation Machine needs age 50+; some mutations are far more sought after than others.
Before accepting a big trade, compare recent completed trades for the same pet, weight and mutation in active trading communities, and use a trusted middleman for high-value deals.
📐 Grow a Garden KG Calculator & Pet Size Classes
Pet weight in Grow a Garden is measured in kilograms (kg) and grows every time the pet ages. Each age adds one-eleventh of the pet's Age-1 (hatch) weight:
Example: a pet showing 3.30 kg at age 20 has an Age-1 weight of 11 × 3.30 ÷ 30 = 1.21 kg, so at age 500 it will weigh 1.21 × 510 ÷ 11 ≈ 56.1 kg. Use the Pet KG calculator above to do this for any pet.
🏷️ Grow a Garden Pet Size Classes
Size classes are community labels based on the Age-1 (hatch) weight. Sources differ slightly on exact cutoffs; these are the ranges they broadly agree on:
- Small: under 1 kg at age 1
- Normal: 1–5 kg at age 1
- Huge: 5–7 kg at age 1
- Titanic: about 7–9 kg at age 1
- Godly: 9 kg or more at age 1
"Titanic" and "Godly" are size labels any species can reach, not separate pets.

❓ Pets FAQ
How many pets can I equip at once?
You start with 3 pet slots. Upgrade up to 8 slots via in-shop purchases (50K → 2M₡ each), the Gamepass (499 Robux), or reaching Player Level 50 for a free bonus slot.
How do I increase my pet's weight?
Level it up. Weight grows with age — every age adds one-eleventh of the Age-1 weight, so Weight = Age-1 weight × (Age + 10) ÷ 11. Gaining XP raises age — project the XP you need with the age calculator. The Age-1 weight itself is fixed when the pet hatches, which is why heavy hatchlings (Huge and above) are valued.
Can I sell my pets in Grow a Garden?
No, pets can only be traded player-to-player. See how pet trade value works for what drives a pet's value. Crop sell prices and WFL checks are on the homepage Grow a Garden calculator.
What's the rarest pet?
Prismatic is the highest pet rarity, and this calculator lists 17 Prismatic pets. Kitsune — the first Prismatic pet — has a 0.08% (1 in 1,250) hatch chance from the Zen Egg. Many limited pets can no longer be hatched at all, which makes them rarer in practice.
Do pet abilities stack?
Yes — each pet's ability triggers independently. Running Butterfly + Disco Bee + Kitsune means you get Rainbow conversion + Disco + Foxfire all on the same plot.
Pet kg lives here. Crop value, mutation stacks, and WFL trades are on the homepage.
