Yorkie Weight Predictor
Estimate how big your Yorkie puppy will be full grown — down to the day
Yorkie Weight Predictor
Enter your puppy's exact age and current weight for a full-grown estimate
Enter an age and current weight above to see the estimate.
This is an estimate, not a guarantee. Every puppy grows on its own curve, and factors like genetics, parentage, nutrition, and health all shift the final number. Predictions are most reliable between about 8 and 16 weeks of age. For the tiniest micro and teacup Yorkies, always plan for a healthy range rather than an exact target.
Yorkie Growth Reference
Roughly what percentage of adult weight a Yorkie has reached at each age.
| Age | Share of adult weight |
|---|---|
| 6 weeks | ≈ 25% of adult weight — multiply current weight × 4 |
| 8 weeks | ≈ 34% of adult weight |
| 10 weeks | ≈ 42% of adult weight |
| 12 weeks | ≈ 50% of adult weight — roughly half grown |
| 16 weeks | ≈ 63% of adult weight |
| 6 months | ≈ 80% of adult weight |
| 9–10 months | ≈ 100% — most Yorkies are done growing |
How the predictor works
Yorkshire Terriers follow a predictable growth curve. This tool takes your puppy's current weight and divides it by the fraction of adult weight a Yorkie has typically reached at that exact age — that's why entering the extra days on top of the weeks sharpens the estimate. It blends the two rules of thumb Yorkie breeders have used for years — a puppy's weight at 6 weeks times four, and its weight at 12 weeks times two — with toy-breed growth benchmarks all the way to full-grown around 9 to 10 months.
Weigh your puppy on an accurate kitchen or postal scale (ounces or grams are perfect for tiny babies), enter the number, choose the sex if you know it, and you'll get a full-grown estimate with a realistic range.
