How big will your puppy get? This free puppy weight calculator predicts your puppy’s adult weight from their age and current weight. If you pick an expected adult size, it adds a second estimate based on typical growth, and shows you a likely range. You also see how much of their growth is done and which size group they will probably fall into.
How to use:
- Enter your puppy’s age in weeks or months (8 weeks to 12 months).
- Enter your puppy’s current weight in kg or lb.
- Optionally choose the expected adult size for a second estimate.
- Click Calculate to see the predicted adult weight and range.
FAQs:
Q: How do you predict a puppy’s adult weight?
A: A common formula divides the puppy’s current weight by their age in weeks and multiplies by 52. This calculator also compares it with typical growth for your chosen size.
Q: How accurate is a puppy weight calculator?
A: It gives an estimate, not a promise. Accuracy is best from about 4 to 6 months, and lower for mixed breeds or very young puppies.
Q: When do puppies stop growing?
A: Small breeds are usually fully grown at 9 to 12 months. Large and giant breeds can keep growing until 18 to 24 months.
Q: Can I use this for a mixed-breed puppy?
A: Yes, but the range will be wider. Knowing the size of the parents helps, and your vet can give a better prediction.
