Yorkshire Terriers are among the smallest dog breeds in the world. A full-grown Yorkshire Terrier measures between 7 and 8 inches (18 and 20 centimeters) at shoulder length. They weigh around 7 pounds (3.2 kilograms) and have a neck size between 2 and 12 inches (15 and 30 kilograms).
Most people want a small dog. Either because they are easier to handle, or because they find them cute.
This makes the Yorkie perfect. But how big do they get with age and how fast do they grow?
This article explores the size of Yorkshire Terriers. You will learn how to predict the adult weight of your Yorkie, how they normally grow, and more.
How Big Do Yorkies Get?
Full-grown Yorkies measure between 5 and 8 inches (13 and 20 centimeters) in height and weigh between 2 and 7 pounds (0.9 and 3.2 kilograms). Their neck size ranges between 4 and 12 inches (10 and 30 centimeters).
There are two types of Yorkshire Terriers: standard and teacup.
Teacup Yorkies are not recognized by the American Kennel Club.
Female Yorkshires are usually smaller than males. Their height is 1 to 2 inches (2.5 and 5 centimeters) shorter and their weight is 1 to 2 (0.45 and 0.9 kilograms) pounds lighter.
Standard Yorkies | Teacup Yorkies | |
Height | 7–8 in (18–20 cm) | 5–7 in (13–18 cm) |
Weight | 7 lbs (3.2 kg) | 2–4 lbs (0.9–1.8 kg) |
Neck size | 6–12 in (15–30 cm) | 4–8 in (10–20 cm) |

When Do Yorkies Stop Growing?
Yorkshire Terriers stop growing when they are one year old. Their growth slows down at the age of 9 months. At this point, standard Yorkshire Terriers weigh around 7 pounds (3.2 kilograms) and measure between 7 and 8 inches (18–20 centimeters) in height.
Yorkshire Terriers, like other small breeds, fully mature earlier. While some breeds reach their maximum height at 16 to 18 months, Yorkies don’t grow after the age of 12 months.
This table illustrates the growth stages of Yorkshire Terriers.
Growth Stage | Age | Description |
Neonatal | 0–2 weeks old | Yorkie puppies are not able to hear or see. Their teeth are absent and they rely highly on their mother. They need to feel secure despite their increased sleeping rates. During this stage, Yorkies face a high mortality risk due to bacterial infections. |
Transitional | 2–4 weeks old | During this stage, Yorkie’s eyes and ear canals begin to open. 4 Weeks old Yorkie puppies start to rely on their vision. Yorkies make connections with their siblings and develop a sense of togetherness. They learn to wag their tail and express their emotions. |
Socialization | 4–12 weeks old | Yorkies’ hearing and smelling abilities fully develop. 3 months old Yorkie puppies can stand, play, and run. Socializing Yorkies during this period is essential and a key factor to reduce anxiety and behavior issues in adulthood. |
Juvenile | 10–16 weeks old | The teeth of Yorkies fully develop. During the juvenile stage, Yorkies look up to you. This makes this period perfect for training. |
Early adolescence | 4–6 months old | Yorkie puppies begin having sexual drive. They form strong bonds with their owners and learn obedience. |
Adolescence | 6 – 12 months old | Yorkie puppies reach sexual maturity. They get acquainted with their gender-specific hormonal changes. This is when they exhibit independent behavior. |

What influences Yorkie adults’ size?
The factors that affect Yorkie size are genetics, nutrition, exercise, and health issues.
Genetics
A Yorkie’s size is highly influenced by genetics.
The best example of how genetics influence size is the teacup Yorkie. They are the result of mixing dwarf Yorkies or mixing a Yorkie with another teacup breed.
Nutrition
Nutrient deficiencies can lead to hormonal changes that influence Yorkie’s growth. Yorkshires that don’t get enough calcium or other key nutrients can experience low bone density.
Exercise

Well-balanced hormone levels are essential for stable growth. That also means regular exercise is crucial.
Yorkshire Terriers need daily walks to keep a healthy weight. Don’t overdo it as their sugar levels decline quickly. The daily exercise needs of Yorkies is around 30 minutes per day.
Not enough exercise can make your Yorkie overweight. If they weigh more than 7 pounds, make sure to increase their physical activity.
Health Issues
There are two health issues that influence growth in Yorkies.
One is acromegaly, a disease that makes Yorkies produce more growth hormones than normal[1]. As a result, they are larger than most Yorkshire Terriers.
The other is Pituitary Dwarfism, in which Yorkies produce fewer growing hormones than they should[2]. Yorkies with dwarfism are smaller than the standard size.
Growth disorders in Yorkies cause the following symptoms:
- Joint pain
- Bowed legs
- Muscle wasting
- Difficulty walking
- Abnormal posture
- Hip dysplasia
Yorkie Growth Chart
The average weight of standard Yorkshire Terriers is 7 pounds (3.2 kilograms). At birth, Yorkies weigh between 2 and 5 ounces (57 and 142 grams). 3-months-old Yorkies weigh between 22 and 41 ounces (0.6 and 1.2 kilograms) while 6-months-old Yorkies weigh between 33 and 60 ounces (0.9 and 1.7 kilograms).
Yorkshire Terriers experience the fastest growth rate between 8 and 10 months old. Their adult size differs according to their size at birth.
This applies to puppies born when they are fully developed in the womb, and not premature puppies.

The Yorkie Weight Chart Calculator Methods
If you don’t have a table to help you predict the weight of your Yorkie, there are two methods that help you do it. These formulas require you to use the weight of the puppy at 8 weeks, while the other uses their 12-week weight.
The 8-week Method
Note your 8-week-old Yorkie puppy’s weight. Multiply it by three to get the approximate age of your future adult Yorkie.
The 12-week Method
Note your 3 months-old Yorkie’s weight. Multiply it by two to get their weight at maturity.
