Pet Sizes in Grow a Garden: Normal, Huge, Titanic and Godly
By Jordan Lee · Pet Mechanics Specialist · Updated
Pet sizes in Grow a Garden are four tiers: Normal, Huge, Titanic and Godly. Sources that publish kilogram lines put Huge at 5 kg and Godly at 9 kg. Titanic starts at 7 kg in some sources and 8 kg in others. GAGdata shows every size number as reported until it is confirmed in game.
What Are Pet Sizes in Grow a Garden?
Grow a Garden is a Roblox farming game. In this game, a pet size is the weight class of a pet. It is not the pet species and it is not the pet rarity. Rarity tells you how hard a pet is to hatch. Size tells you how heavy it is.
Pet size here does not mean avatar scale or crop size. The four tiers are Normal, Huge, Titanic and Godly. Normal is the default. This page is part of the Pets hub. It puts the four tiers side by side, shows where sources agree, and marks every number that is still open.
GAGdata does not hold a confirmed in-game test for the size lines yet. Each figure below is labelled Reported, Conflict or PENDING. The date checked is October 28, 2026.
Pet Size Tiers Compared: Normal, Huge, Titanic and Godly
The table lists the tiers in order. The line column shows the hatch weight where a tier starts, as reported by outside calculators. Use the guide column to go to the full page for a tier.
| Order | Tier | Starting line | Status | Notes | Guide |
|---|---|---|---|---|---|
| 1 | Normal | Below the Huge line | Baseline | Every pet starts here unless its hatch weight clears the Huge line. | Pet Weight Calculator |
| 2 | Huge | 5 kg hatch weight | Reported | Four sources give the same starting line. Not yet confirmed in game by GAGdata. | Huge Pets Guide |
| 3 | Titanic | ⚠️ PENDING | Conflict | 7 kg in two sources, 8 kg in two others. The line is PENDING. | Titanic Pets Guide |
| 4 | Godly | 9 kg hatch weight | Reported | Four sources give the same starting line. Not yet confirmed in game by GAGdata. | Godly Pets Guide |
Pet Size Thresholds by Source: Huge, Titanic and Godly
These lines come from three outside calculators we read on October 28, 2026, and from the text of the GAGdata Pet Weight Calculator. Values are in kilograms. The basis column says whether the source states hatch weight.
| Source | Huge | Titanic | Godly | Basis |
|---|---|---|---|---|
| GagTools Pet Weight Calculator | 5 to 6.99 kg | 7 to 8.99 kg | 9 to 9.99 kg | Hatch weight at age 1 |
| GAG Calculator (gagcalculator.app) | 5 to 7 kg | 8 to 9 kg | 9 kg and up | Not stated |
| growagrdencalculator.com | 5 to 8 kg (table) or 5 to 7 kg (widget) | 8 to 9 kg | 9 kg and up | Not stated. The page contradicts itself on Huge. |
| GAGdata Pet Weight Calculator | 5 to 7 kg | 7 to 9 kg | 9 kg and up | Hatch weight (calculator text) |
Huge and Godly agree across all four sources. Titanic does not. GagTools and the GAGdata calculator start Titanic at 7 kg. gagcalculator.app and growagrdencalculator.com start it at 8 kg. A pet with a hatch weight between 7 kg and 8 kg could be Titanic or Huge, depending on which source is right.
GAGdata lists the Titanic line as PENDING. It needs an in-game test by Sam Rivers. None of the pages we read shows a test method, so treat every figure here as reported, not confirmed.
How Pet Size Connects to Weight, Age and XP
Two outside calculators and the GAGdata Pet Weight Calculator quote the same weight formula: W = (Wh / 11) x (A + 10). W is current weight, Wh is hatch weight and A is age. One of them states a 2% error margin. We have not tested that margin.
Under this formula a pet gets heavier as it ages, and hatch weight is the starting point. The Pet Weight Calculator does the arithmetic for you.
Pet age comes from XP. The Pet XP and Leveling guide covers XP per hour, age milestones and the XP curve. This page does not repeat those numbers.
Two models are live on GAGdata. The Titanic and Godly guides describe sequential XP upgrades from Normal to Huge to Titanic to Godly. The weight calculator sets the class from hatch weight. The two do not match. The question is open and listed in the data status table below.
Pet Size Values in the GAGdata Pet Database
The GAGdata pet database holds Huge, Titanic and Godly values for 337 of 359 pet entries. It was last updated June 22, 2026. The other 22 entries have no values yet.
In 336 of the 337 entries, the Titanic value is exactly 3 times the Huge value and the Godly value is exactly 8 times the Huge value. One entry differs. That pattern is a data fact. It is not a game rule.
The Titanic guide and the Godly guide read these values as XP thresholds. The weight calculator works in kilograms. The unit is PENDING, so this page prints no per-pet numbers. Look a pet up in the tier guides instead.
Do Bigger Pets Trade for More?
Size can change a pet's trade value by a lot. The pet database lists Queen Bee near 1,650,000 at base and near 137,830,000 as Huge. The source is TradeKitsune, anchored May 10, 2026, and the database marks that value as settling.
No confirmed size multiplier exists, so this page publishes none. Check Pet Values for dated numbers and the Pet Trading Guide for fair trade rules.
How to Check Your Pet's Size
Use the Pet Weight Calculator to find a size class. It takes a pet, its age and its weight, and works back to the hatch weight.
- Open the Pet Weight Calculator. Open the GAGdata Pet Weight Calculator. It lists the pets in the GAGdata database.
- Pick your pet. Select the pet species from the list. Use the exact species name shown in your inventory.
- Enter age and weight. Type the pet's current age and its current weight in kilograms. The calculator works back to the hatch weight.
- Read the size class. Read the class the calculator returns: Normal, Huge, Titanic or Godly. Compare it with the reported lines on this page.
- Check the Titanic edge case. If the hatch weight sits between 7 kg and 8 kg, treat the class as unconfirmed. Sources disagree on the Titanic line.
Pet Size Data Status: Reported, Conflicting and PENDING
| Item | Status | Detail |
|---|---|---|
| Four size tiers in order | Reported | Normal, Huge, Titanic, Godly. Shown on the GAGdata Titanic and Godly guides and used by the weight calculators. |
| Huge line, 5 kg | Reported | Same value in four sources. In-game check by Sam Rivers is open. |
| Titanic line | Conflict | 7 kg (GagTools, GAGdata calculator) against 8 kg (gagcalculator.app, growagrdencalculator.com). |
| Godly line, 9 kg | Reported | Same value in four sources. In-game check by Sam Rivers is open. |
| Weight formula | Reported | W = (Wh / 11) x (A + 10), quoted by two outside calculators and the GAGdata calculator. Error margin is not confirmed. |
| Does XP alone change the size tier? | ⚠️ PENDING | The Titanic and Godly guides say yes. The weight model sets the tier from hatch weight. |
| Can a pet skip a tier? | ⚠️ PENDING | Depends on which model is right. |
| Size value multiplier | ⚠️ PENDING | No confirmed figure. Use Pet Values for dated numbers. |
| Per-pet thresholds and unit | ⚠️ PENDING | Stored in the pet database. The unit (XP or kg) is not confirmed. |
