A Maltipoo has no kennel-club breed standard and no single adult weight: depending on which Poodle was used, an adult runs 4 to 15 lb (2 to 7 kg). The charts below give a month-by-month range for each pairing.
Quick answers
- There is no Maltipoo breed standard. The American Kennel Club does not recognise the cross, so no adult weight range is set by a kennel club.
- Size depends on which Poodle was used. A first cross lands between its two parents: toy poodle cross 4–7 lb; miniature poodle cross 4–15 lb.
- Every figure is an AKC standard for one of the two parent breeds; no association sets a standard for this cross.
- If you do not know the category, the puppy weight calculator estimates adult weight from your puppy’s age and weight today, which is the better tool here.
Maltipoo growth chart by size
Each table below covers one parent pairing. Its range runs from the lighter parent’s standard to the heavier one’s, because a first-generation cross lands between its parents, and it is scaled by the growth curve for the size class that span falls in. Ask the breeder which Poodle was used; that choice, more than anything else, decides which table is yours.
Toy Poodle cross Maltipoo
Maltese × Toy Poodle. The Maltese standard is under 7 lb and the Toy Poodle's AKC figure is 4 to 6 lb, so the cross has nowhere else to land.
| Age | Weight range | % of adult |
|---|---|---|
| 2 months | 2–3 lb0.7–1.1 kg | 36% |
| 3 months | 2–3 lb0.9–1.6 kg | 49% |
| 4 months | 2–4 lb1.1–1.9 kg | 61% |
| 6 months | 3–5 lb1.4–2.5 kg | 76% |
| 9 months | 3–6 lb1.6–2.8 kg | 87% |
| 12 months | 4–7 lb1.7–2.9 kg | 92% |
| 18 months | 4–7 lb1.7–3.1 kg | 96% |
| 24 months | 4–7 lb1.8–3.2 kg | 100% |
Miniature Poodle cross Maltipoo
Maltese × Miniature Poodle. The Miniature Poodle's AKC figure is 10 to 15 lb, so this pairing can run to twice the weight of the toy cross.
| Age | Weight range | % of adult |
|---|---|---|
| 2 months | 2–5 lb0.7–2.4 kg | 36% |
| 3 months | 2–7 lb0.9–3.3 kg | 49% |
| 4 months | 2–9 lb1.1–4.1 kg | 61% |
| 6 months | 3–12 lb1.4–5.2 kg | 76% |
| 9 months | 3–13 lb1.6–6 kg | 87% |
| 12 months | 4–14 lb1.7–6.2 kg | 92% |
| 18 months | 4–15 lb1.7–6.6 kg | 96% |
| 24 months | 4–15 lb1.8–6.8 kg | 100% |
Weigh on the same scale at the same time of day where you can. The trend across several weighings tells you far more than any single row, and in a cross it is the only thing that narrows the answer.
Where these numbers come from
No kennel club or breeder association publishes a standard for the Maltipoo, so this page does not invent one. Every weight range above is built from the American Kennel Club standards of its parent breeds — the Maltese, Toy Poodle and Miniature Poodle pages on this site carry those standards and their sources — and a first-generation cross is taken to land between its two parents. That is why the ranges are wider than on a breed page: they cover everything the two parents allow, not a figure someone chose.
The month-by-month ranges are not measurements of Maltipoos. They are the same growth curves used everywhere on this site — built from 8,459,668 veterinary bodyweight records published by Salt and colleagues — applied to each size category’s adult range. That research found dogs of similar adult size grow on similar curves whatever the breed, which is what makes the arithmetic valid for a cross with no standard of its own. The derived table, the filtering steps and the known gaps are published in full.

Other toy breeds
A Maltipoo sits in the toy size class at the category this page is filed under, so these breeds share its growth curve. Each has an American Kennel Club standard behind its numbers, which a cross does not.
Frequently asked questions
How big will my Maltipoo get?
That depends on which Poodle was used. A Maltese crossed with a Toy Poodle lands between 4 and 7 lb as an adult, because both parents’ American Kennel Club figures sit in that range. A Maltese crossed with a Miniature Poodle can reach 15 lb. If you do not know the pairing, enter your puppy’s age and current weight into the calculator on the home page.
Is there a Maltipoo breed standard?
No. The American Kennel Club does not recognise the Maltipoo and no breeder association publishes a standard for it. The ranges on this page are built from the AKC standards of the two parent breeds, the Maltese and the Poodle, which is why they are given per pairing rather than as one figure.
How much does a Maltipoo weigh in kg?
A Maltese × Toy Poodle cross lands between about 1.8 and 3.2 kg as an adult; a Maltese × Miniature Poodle cross between about 1.8 and 6.8 kg. Each table above gives kilograms under the pounds at every month.
When is a Maltipoo fully grown?
A Maltipoo is close to adult weight by about 12 months. Both parent breeds are toy or small dogs, and small dogs reach their adult weight sooner than large ones; the last few percent can still fill in over the following months.
Why is my Maltipoo bigger than the breeder said?
Breeders’ estimates for a cross are guesses, and the Poodle parent is the usual reason they miss. If a Miniature Poodle was used anywhere in the line, the puppy can outgrow a toy-cross estimate by several pounds and still be entirely normal for its parentage.
Is my Maltipoo puppy underweight if it is below the chart?
Not necessarily. At this size a meal or a full bladder moves a puppy a visible distance on the chart. A puppy that is consistently below its range and not gaining, or has dropped from a higher line to a lower one, is worth a vet visit; a single low reading is not.
How can I tell if my Maltipoo is a healthy weight?
Body condition tells you more than the scale, and under a Maltipoo’s coat it has to be done by hand. You should be able to feel the ribs under a thin layer of fat without pressing and see a waist from above. A dog can sit inside its range and still carry too much fat.
