When I first brought my little Maltese home, I was amazed at how tiny she was, barely the size of a loaf of bread, yet full of energy and personality. Like many new pet parents, I often found myself wondering, How big will she get? and is she growing normally for her age?. These are questions almost every Maltese owner asks, especially because this breed can vary slightly in size depending on genetics and breeding lines.
The Maltese dog is one of the most elegant and compact toy breeds, known for its silky white coat and lively temperament.
Despite their small frames, these dogs are surprisingly sturdy, active, and confident. Their size makes them perfect companions for apartment living, frequent travelers, and families who want a loyal, loving lapdog.

How Big Do Maltese Dogs Get?
The Maltese dog may look tiny, but don’t let that size fool you, these little fluffballs are full of personality. Generally, a fully grown Maltese stands between 7 to 9 inches tall and weighs around 4 to 7 pounds, depending on their genetics and diet. Some may be slightly larger or smaller, especially if they come from different breeding lines or mixes.
Because of their petite frame, they’re one of the most travel-friendly companion dogs around, perfect for city apartments or homes with limited space. In fact, their small, portable size is one of the biggest pros of owning a Maltese, especially for people who love to have their pets by their side wherever they go.
Despite being small, they’re sturdy and active enough to enjoy short walks, play sessions, and light exercise. Their growth happens quickly during the first few months, and by the time they reach their first birthday, most Maltese have already reached their adult size.

Generally, males tend to have a slightly stockier frame and may weigh just a bit more than females, who are often more petite and fine-boned. Here’s a quick comparison chart to illustrate the differences:

| Average Weight | 5–7 pounds | 4–6 pounds |
| Build | Slightly muscular | Slender and delicate |

Maltese Height and Weight Chart by Age
Tracking your Maltese’s growth is a good way to make sure they’re healthy and developing at the right pace. A Maltese height and weight chart by age helps new owners understand what to expect from puppyhood to adulthood.
Since Maltese dogs are small-breed canines, they grow faster than larger dogs, usually reaching adult height by 8 months and adult weight by 12 months. Factors like diet, exercise, and genetics can slightly affect growth patterns, so regular check-ins with your vet are always recommended.
| Age | Height (cm) | Height (in) | Weight (kg) | Weight (lbs) |
| 2 months | 10 – 13 cm | 4 – 5 in | 0.9 – 1.3 kg | 2 – 3 lbs |

Teacup Maltese Size – Smaller Than Standard
The Teacup Maltese is a miniature version of the standard Maltese, bred to be even tinier and more delicate. Typically, they weigh under 4 pounds and stand around 6 inches tall, making them one of the smallest dogs in the world.
Their tiny size means they can easily fit into small living spaces, purses, or travel bags, which is a big reason they’ve become so popular among city dwellers and influencers.
However, that small size comes with a trade-off. Teacup Maltese dogs are more prone to health issues such as low blood sugar, fragile bones, and breathing problems. They require extra care, gentle handling, and frequent small meals to stay healthy.
Because of their fragility, they’re not ideal for families with small children or large pets. Still, for those who can dedicate time and care, Teacup Maltese dogs offer the same loyal, affectionate companionship the breed is known for just in a smaller, more delicate package.
Maltese Size Compared to Other Small Breeds
When comparing the Maltese dog to other small breeds, it becomes clear that this breed sits perfectly in the middle of the toy dog category. They’re not as tiny as a Chihuahua, but smaller and lighter than a Shih Tzu or Pomeranian. Despite their delicate looks, Maltese dogs have sturdy bodies and a surprisingly confident stance.
They’re often compared to breeds like the Yorkshire Terrier, Pomeranian, or Bichon Frise, which share similar energy levels and grooming needs. Here’s a quick comparison to help you understand how the Maltese fits among other small breeds:

| Shih Tzu | 8–11 inches | 9–16 lbs | 10–16 years | Calm, friendly |
| Yorkshire Terrier | 7–8 inches | 4–7 lbs | 12–15 years | Confident, spirited |
Maltese Mix Breeds and Their Size Variations
Maltese mix breeds can vary widely in size depending on the breed they’re paired with. Some mixes, like the Maltipoo (Maltese + Poodle), may have a slightly taller frame due to Poodle genes, while others, such as the Morkie (Maltese + Yorkie), retain the compact, toy-like proportions of the Maltese.
Size variations also depend on whether the mix is bred with a toy or miniature version of the other breed. Below is a table outlining a few popular Maltese mixes and their average size ranges:
| Maltese Mix Breed | Height | Weight | Build | Notable Feature |
| Maltipoo (Maltese + Poodle) | 8–12 inches | 5–12 lbs | Compact, soft coat | Curly or wavy fur |
| Morkie (Maltese + Yorkie) | 7–9 inches | 5–10 lbs | Small, agile | Silky coat |
| Malshi (Maltese + Shih Tzu) | 8–10 inches | 6–12 lbs | Stocky | Round face, fluffy coat |
| Malchi (Maltese + Chihuahua) | 6–9 inches | 4–9 lbs | Slim | Alert, expressive eyes |
| Havamalt (Maltese + Havanese) | 8–12 inches | 6–13 lbs | Balanced | Wavy coat, calm nature |
Each mix brings its own charm, some are better for allergy-prone owners, while others are more playful or low-maintenance.

How to Maintain a Healthy Weight for Your Maltese
A balanced diet and proper exercise routine help your Maltese stay in top shape. Overfeeding is one of the most common issues for small breeds, even a few extra treats can quickly lead to excess weight. Here are a few ways to keep your Maltese fit and healthy:
- Feed small, measured portions instead of leaving food out all day.
- Choose high-quality small-breed dog food rich in protein and low in fillers.
- Stick to regular exercise, such as two short walks and indoor playtime.
- Monitor treats and table scraps, as these can add calories fast.
- Weigh your Maltese monthly to track fluctuations.
Maintaining a steady, healthy weight not only improves energy levels but also extends lifespan and prevents joint issues.
Does Size Affect Maltese Temperament or Lifespan?
In general, size doesn’t directly change a Maltese’s personality, they’re known for their affectionate, cheerful nature regardless of weight. However, smaller Maltese (especially teacup varieties) can sometimes be more fragile and reserved due to their delicate build.
Interestingly, studies show that smaller Maltese often live longer than larger ones, as their bodies experience less physical strain. Still, longevity depends heavily on genetics, diet, and care rather than size alone.
No matter their height or weight, all Maltese share a similar temperament, loyal, loving, and always eager to be close to their favorite person.
