1. What is the Puppy Size Calculator?

The puppy size calculator estimates how big your puppy will get as an adult based on their current weight and age. This simple formula provides a rough estimate of adult size for growing puppies.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

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

Explanation: The formula assumes linear growth rate during puppyhood to estimate adult size.

3. Accuracy of the Calculation

Details: This method provides a rough estimate. Actual adult size can vary based on breed, genetics, nutrition, and other factors. It works best for medium-sized breeds and when used between 12-20 weeks of age.

4. Using the Calculator

Tips: Weigh your puppy accurately and enter their exact age in weeks. For best results, weigh your puppy at multiple points and average the estimates.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides a rough estimate (±15% accuracy) for most medium-sized breeds. Giant and toy breeds may have less accurate predictions.

Q2: When is the best time to calculate puppy's adult size?
A: Between 12-20 weeks of age tends to give the most reliable estimates.

Q3: Does this work for all dog breeds?
A: It works best for medium-sized breeds. Giant breeds grow for longer periods, while small breeds mature faster.

Q4: Can I use pounds instead of kilograms?
A: Yes, but the formula was designed for metric measurements. For pounds, the result will also be in pounds.

Q5: What other methods predict adult dog size?
A: Breed standards, paw size, and parent sizes can also help estimate adult size. DNA tests may provide growth predictions for some breeds.
