Maltese size: how big does a full-grown Maltese get?
The Maltese comes in one honest toy size, no mini and no standard. Here is the full-grown weight and height, the month-by-month growth chart, why teacup is a label rather than a size, and what a 2 to 3kg frame means for your flat, your kids and your travel plans.

How big does a full-grown Maltese get?
A full-grown Maltese is a single toy size, about 2 to 3kg (occasionally up to 4kg) and 20 to 25cm at the shoulder. The AKC standard calls for under 7 pounds. Most reach adult weight by around 9 months and are fully mature by 12 to 14 months. There is no mini, standard or teacup size.
How big does a full-grown Maltese get?
The Maltese comes in one size, and it is genuinely small. A full grown adult weighs about 2-4kg, with 2 to 3kg most typical, and stands roughly 20 to 25cm at the shoulder. That places the breed among the smallest members of the toy breed group, smaller than a Shih Tzu or Bichon Frise and in the same tiny bracket as the Chihuahua and Yorkshire Terrier.
In practical terms, a Maltese is a lap dog in the most literal sense: light enough to carry in one arm (though you should use two, more on that below), small enough to share a sofa cushion, and compact enough that a flat is all the territory it needs. The height and weight barely differ between individuals, which is exactly why any listing offering a choice of Maltese sizes should make you pause.

Maltese growth chart: month by month
Overseas charts quote everything in pounds, which is useless when your Singapore vet weighs in kg. Here is the metric-first growth chart we give new owners, calibrated to the roughly nine-week go-home age our puppies leave at. A Maltese puppy does most of its growth in the first six months, then the curve flattens quickly.
| Age | Typical weight | What is happening |
|---|---|---|
| 8-9 weeks (go-home) | ~0.7-1.2kg | Tiny; feed small meals often to guard against low blood sugar |
| 3 months | ~1.2-1.8kg | Fastest growth phase; weigh weekly on a kitchen scale |
| 4-6 months | ~1.5-2.5kg | Growth slowing; teething; adult coat starting |
| 9 months | ~2-3kg | At or near adult weight for most |
| 12-14 months | ~2-4kg | Fully mature frame and silky adult coat |
When does a Maltese stop growing?
A Maltese stops growing in two stages. Weight plateaus first: most puppies reach their adult weight by around 9 months, some a little earlier, the odd one closer to a year. The frame, chest and the long silky coat take longer, so a Maltese is not fully mature in build and coat until about 12 to 14 months.
What that means day to day: after the first birthday, any meaningful weight change is diet, not development. Steady gain in a young puppy is healthy; the same gain in an 18-month-old is heading toward overweight. If a puppy is losing weight at any age, or a six-month-old has stalled well under the chart above, that is a vet conversation, not a wait-and-see.
What the breed standards actually say
The numbers above are not our opinion; they track the official standards. The AKC breed standard calls for a Maltese under 7 pounds (about 3.2kg), with 4 to 6 pounds preferred, and the parent club, the American Maltese Association, describes the same compact, fine-boned toy dog. The European FCI standard runs slightly heavier, listing 3 to 4kg, with a height of roughly 21 to 25cm for a male and 20 to 23cm for a female.
The takeaway is not which breed standard is "right". It is that every major kennel club on earth describes the same single small dog. A healthy purebred Maltese anywhere in the 2 to 4kg band is normal; there is no standard anywhere that recognises a bigger or smaller variety.
One size only: why there is no mini or standard Maltese
Some breeds genuinely come in sizes; the Poodle, for instance, has three recognised varieties. The Maltese does not. There is no "mini Maltese", no "standard Maltese", no size chart to choose from. When a listing splits the breed into tiers, that is marketing built on a breed that is already tiny, usually to justify a premium for the word "small" on a dog that was always going to be small.
A responsible seller can tell you the parents' sizes and give an honest estimate, but nobody can promise a final adult weight, because normal litters produce normal variation. What we can promise is the range: every healthy Maltese lands somewhere in that same 2 to 4kg toy band.
'Teacup' is not a size, and smaller is not better
This is the part of the size conversation most sellers skip. A "teacup" Maltese is not a recognised size in any standard. In practice the label is attached to the runt of a litter, to a normal puppy photographed very young, or worst of all, to puppies deliberately bred for extreme smallness. That last practice carries real costs: fragile bones that break in falls a normal Maltese would shrug off, hypoglycaemia (dangerous low blood sugar), heart and dental problems, and vet bills to match.
Be honest with yourself about the appeal. If you want a tiny white companion, the ordinary Maltese already is one; at 2 to 3kg it is one of the smallest dogs that exists. Paying more for the promise of "under 1.5kg forever" means paying a premium for elevated health risk. We refuse to use the label, and our teacup Maltese guide explains the whole picture before you answer any such listing.
Weight vs condition: what a healthy Maltese looks like
Owners fixate on the scale, but vets judge body condition, and you can too. Run your fingers along your dog's side: you should feel the ribs easily under a light layer of padding without seeing them. From above, there should be a visible waist behind the ribcage; from the side, a slight tummy tuck. A Maltese that passes that check is healthy whether it weighs 2.2kg or 3.6kg.
Staying lean matters more here than in most breeds, because on a 3kg frame an extra 300g is a ten percent overload, and the breed is prone to luxating patella, a slipping kneecap that extra weight aggravates. Measure meals rather than free-feeding, keep treats inside the daily budget, and do the rib-and-waist check monthly. Our lifespan and health guide covers the knees, the heart and the rest of the long-term picture.
The 30-second monthly check
- Ribs: easy to feel, not see
- Waist: visible from above
- Tuck: belly rises behind the ribs
- Weigh on a kitchen scale, same time of day
- Drifting up after 12-14 months = diet, not growth
Male vs female Maltese size
The difference is real but minor. A male Maltese averages slightly larger and often sits at the upper end of the range, while a female tends toward the lower end, and the FCI height figures reflect that by a couple of cm. The overlap is huge though: plenty of females outgrow plenty of males. If you are choosing between the two, the gentle companion temperament is near-identical across sexes, so pick on personality and fit, not on a few hundred grams.
Carrying and handling a 2-3kg dog safely
Here is what no growth chart tells you: the biggest size-related risk to a Maltese is not being too big or too small, it is being dropped. A delicate toy frame does not forgive falls. Always lift with two hands, one supporting the chest and one under the hindquarters, and hold the dog against your body rather than at arm's length. Teach children to sit on the floor to hold the puppy, never to walk around carrying it, and supervise every interaction with small kids.
Think about heights at home too. A leap off a sofa or bed is a long drop in proportion to a 25cm dog and a common cause of injured knees and broken forelegs in toy breeds. Pet stairs or a ramp beside the favourite couch, a no-jumping habit trained early, and picking the dog up for staircases all cost little and prevent the most common size-related accidents. We walk every new owner through this handling routine at collection, because it is the single most useful size advice we can give.
The Singapore angle: HDB flats and cabin-size travel
In Singapore, the Maltese's size is not just charming, it is administratively convenient. The breed is named on HDB's approved list (item 33), so it is a clean yes for flat living, one licensed dog per flat. Its exercise needs fit an apartment routine of short walks and indoor play, and at 2 to 3kg it is easy to manage in lifts, void decks and small spaces. Our HDB-approved guide covers the rules and licensing in full.
The size pays off when you travel, too. A Maltese fits comfortably inside a standard soft-sided pet carrier, and at 2 to 4kg it sits well within the combined dog-plus-carrier limits most airlines set for in-cabin travel, where the option exists on a route. Rules differ by airline and destination, so always confirm the current policy and Singapore's import/export requirements before booking, but few breeds are as genuinely portable.
The size we actually place
Everything above is backed by what we see at handover. Across the 50+ Maltese we have placed with Singapore families, every one has been a standard toy-size, pure white purebred, vet-checked, vaccinated and microchipped, going home at around nine weeks and growing into that same 2 to 4kg adult band. We are an AVS licensed shop, and when you enquire we will tell you the parents' sizes and give you an honest estimate, never a guaranteed number and never a "teacup" promise.

Frequently asked questions
How big does a Maltese get?
A full-grown Maltese is a single toy size, about 2 to 3kg (occasionally up to 4kg) and 20 to 25cm tall at the shoulder.
At what age is a Maltese full grown?
Most reach adult weight by around 9 months and their full frame and coat by 12 to 14 months.
Is there a mini or standard Maltese?
No. The Maltese comes in one toy size. Mini, micro and teacup are marketing labels, not recognised sizes in any breed standard.
How much should an adult Maltese weigh?
The AKC standard calls for under 7 pounds (about 3.2kg), ideally 4 to 6 pounds; the FCI standard lists 3 to 4kg. A healthy adult anywhere in the 2 to 4kg band is normal.
Is a teacup Maltese a real size?
No. Teacup is a sales label, often a runt or a puppy sold very young, and breeding for extreme smallness raises risks like fragile bones and low blood sugar. We do not sell teacup Maltese.
Are Maltese good for small flats?
Yes. The Maltese is named on HDB’s approved list (item 33), and its small toy size suits flat living easily, though it is delicate and needs gentle handling.
Do male and female Maltese differ in size?
Only slightly. Males average a little larger and females a little smaller, but both land in the same small toy range and the overlap is big.
How do I know my Maltese puppy is growing normally?
Use a weight-by-age chart as a sanity check, weigh weekly on a kitchen scale, and let your vet confirm at each vaccination visit. Steady gain and a lean body condition matter more than hitting an exact number.
