Yorkie Weight Chart: How Big Will My Yorkie Get? Complete Growth Guide

If you’ve just brought home a Yorkshire Terrier puppy, one of the first questions you’ll likely ask is: how big will my Yorkie get? It’s a natural concern — and one that affects everything from crate size to nutrition planning.

This guide covers the complete Yorkie growth journey, from birth to adulthood, with weight charts, growth stages, and answers to the most common size-related questions.

Yorkie Weight Chart: Birth to Adulthood

Here’s the average weight range for Yorkshire Terriers at each stage of development. Keep in mind that every Yorkie is an individual — some will be smaller or larger than these averages.

The AKC breed standard for Yorkshire Terriers is 7 pounds (3.2 kg) or under. However, it’s very common to find Yorkies weighing anywhere from 4 to 10 pounds, especially if they’re from mixed breeding lines.

How Much Should a Yorkie Weigh at Each Age?

Here’s a month-by-month breakdown of what to expect during your Yorkie’s first year:

Newborn to 4 Weeks

Yorkie puppies are tiny at birth — typically 2.5 to 5 ounces. They’ll double their birth weight by around 10-14 days old. During this stage, weight gain is the most important indicator of health. A puppy that isn’t gaining weight needs veterinary attention.

4 to 8 Weeks

By 4 weeks, your Yorkie puppy will weigh between 6 and 12 ounces. They’ll start walking, playing, and exploring. By 8 weeks (when most puppies go to their new homes), they should weigh between 12 ounces and 1.5 pounds.

8 to 12 Weeks (2-3 Months)

This is a period of rapid growth. At 8 weeks, a Yorkie weighs around 1-1.5 lbs. By 12 weeks, they should be in the 1.5-3.5 lb range. As one owner asked:

“My yorkie Macy weighs almost 3 lb and she is 3 months old. Is that healthy?”

At 3 pounds for a 3-month-old — that’s perfectly healthy and right on track for an average-sized Yorkie! She’ll likely be in the 5-6 lb range as an adult.

3 to 6 Months

Growth continues but starts to slow down. At 4 months, your Yorkie will be roughly half their adult size. By 6 months, they’ll be about 60-70% of their adult weight.

6 to 12 Months

Growth slows significantly. Most Yorkies reach their full height by 9-10 months, though they may continue to fill out slightly until 12-18 months. At 12 months, your Yorkie should be close to their adult weight.

How Big Will My Yorkie Get? Predicting Adult Size

While no method is 100% accurate, here are some ways to estimate your Yorkie’s adult size:

1. The 6-Week Rule

At 6 weeks old, multiply your Yorkie’s weight by 4 to estimate their adult weight. For example, a 10-ounce puppy at 6 weeks will likely be around 40 ounces (2.5 lbs) as an adult.

2. The 12-Week Rule

At 12 weeks (3 months), double your Yorkie’s weight and add 1 pound. A 3 lb puppy at 12 weeks would be approximately 3 x 2 + 1 = 7 lbs as an adult.

3. The 4-Month Rule

At 4 months, your Yorkie is about half their adult size. Double their 4-month weight for a rough estimate. A 2.5 lb Yorkie at 4 months will likely be around 5 lbs as an adult.

As one owner wondered:

“I have a female Yorkie… She weighs about 1.5 lbs, and is 4 months old. How big will she be as an adult?”

At 1.5 lbs at 4 months, this Yorkie is on the smaller side. Using the 4-month rule (double the weight), she’ll likely be around 3-4 lbs as an adult — on the teacup end of the spectrum.

Factors That Affect Yorkie Size

Genetics (Most Important)

The biggest predictor of your Yorkie’s adult size is their parents’ size. If you know the size of the sire and dam, you have a good idea of where your puppy will land. Yorkies from show lines tend to be smaller, while those from pet lines vary more.

Gender

Female Yorkies are typically slightly smaller than males, though the difference is usually less than a pound.

Nutrition

Proper nutrition during puppyhood is essential for reaching genetic growth potential. Underfeeding can stunt growth, while overfeeding can lead to unhealthy weight gain. Follow your vet’s feeding recommendations for your puppy’s size and age.

Spaying/Neutering Timing

There’s some evidence that early spaying or neutering can affect growth plate closure, potentially leading to slightly taller dogs. Discuss the best timing with your veterinarian.

Teacup Yorkies vs Standard Yorkies

The term “teacup Yorkie” isn’t an official breed classification — it’s a marketing term used to describe smaller-than-average Yorkies (usually under 4 pounds as adults). While they can be adorable, teacup Yorkies come with increased health risks including fragile bones, dental problems, hypoglycemia, and collapsed trachea.

Reputable breeders don’t breed for “teacup” size specifically, as it can involve breeding runts or dogs with health issues. If you’re looking for a smaller Yorkie, focus on finding a healthy, well-bred dog rather than seeking out a specific size label.

When Do Yorkies Stop Growing?

Most Yorkies reach their full height by 9-10 months of age. However, they may continue to fill out and gain a small amount of weight until 12-18 months. Unlike larger breeds that grow for 18-24 months, small breeds like Yorkies mature more quickly.

• Height: Full height by 9-10 months
• Weight: Near full weight by 12 months, may fill out slightly until 18 months
• Emotional maturity: 1-2 years

How to Weigh Your Yorkie at Home

For accurate weight tracking, use a digital kitchen scale for puppies and a small pet scale for adults. Weigh your Yorkie weekly during their first year and monthly after that. Track the results to ensure steady, healthy growth.

1. Weigh yourself on a bathroom scale
2. Pick up your Yorkie and weigh yourself again
3. Subtract your weight from the combined total

Alternatively, many veterinary clinics offer free weigh-ins if you don’t have a scale at home.

Is My Yorkie Overweight or Underweight?

Signs of Healthy Weight

• You can feel their ribs with a slight fat covering (like the back of your hand)
• They have a visible waist when viewed from above
• They have a tucked-up belly when viewed from the side

Signs of Overweight

• Can’t feel their ribs easily
• No visible waistline
• Reluctance to exercise or excessive panting

Signs of Underweight

• Ribs, spine, or hip bones are very prominent
• Visible lack of muscle mass
• Low energy levels

As another owner asked:

“Macy weighs 2.4 pounds. Is that healthy?”

Without the age, it’s hard to say definitively — but 2.4 lbs is a healthy weight for a Yorkie at around 10-12 weeks old. Always check with your vet if you’re concerned about your specific puppy’s growth curve.

Can a Yorkie weigh 10 pounds?
