1. What is the Puppy Weight Calculator?

The Puppy Weight Calculator estimates how big your puppy will get as an adult based on their current weight and age. This simple formula works best for medium-sized breeds.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• Puppy Weight — Current weight in pounds or kilograms
• Puppy Age — Current age in weeks (1-52)
• 52 — Number of weeks in a year

Explanation: The formula assumes linear growth rate during the first year and projects this to estimate adult weight.

3. Accuracy of the Calculation

Details: This calculation is most accurate for medium-sized breeds. Large breeds may continue growing beyond 52 weeks, while small breeds may reach adult weight sooner.

4. Using the Calculator

Tips: For best results, weigh your puppy at 14-16 weeks old. Make sure to use the same units (lbs or kg) consistently.
