Animal fight survival calculator
Enter height, weight and activity. The page scores joking odds against pigeons, a goose, a kangaroo, a bear and a horse-sized duck.
This is a joke about the “how many animals could you beat” trend. Not a zoology guide. Also try the Virtual Punching Machine.
Result
Enter height, weight and activity.
How to use
- Enter height and weight. Units come from the header.
- Pick activity from sitting to heavy training.
- Click Calculate. The bars show each matchup.
- Example: 178 cm, 76 kg and regular movement. Pigeons usually lose. The bear usually does not.
Formula
index = (height/175) × (weight/75) × activity × (1 + (BMI − 22) × 0.015), clamped to 0.28–2.4.
chance = 100 / (1 + e−(index − power) × 3.2). Powers are fixed: 5 pigeons 0.22, kangaroo 1.46, horse-duck 1.88, bear 2.18.
Examples
Example 2
165 cm, 58 kg, light walks.
Example 3
190 cm, 92 kg, heavy training.
Frequently asked questions
What goes into the formula?
Height, weight and activity. Those build a power index, then a chance against fixed opponent powers.
Is the horse-sized duck real?
No. It is a joke about the internet trend. The page does not describe real animals or a real fight.
Why does the bear almost always win?
Because it has a fixed power of 2.18, and the human index is clamped near 2.4. Activity helps. Zoology still wins.
Do US units work?
Yes. The header switch takes inches and pounds, then converts to centimetres and kilograms.
