A Cockapoo has no kennel-club breed standard and no single adult weight: depending on which Poodle was used, an adult runs 4 to 30 lb (2 to 14 kg). The charts below give the typical weight and the usual range by month for each pairing.
Quick answers
- There is no Cockapoo 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: miniature poodle cross 10–30 lb; toy poodle cross 4–30 lb.
- Every figure comes from the AKC for one of the two parent breeds, its standard or its breed-page figure; breeder clubs exist, but no traceable published standard sets this cross’s weight.
- 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.
Cockapoo 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.
Miniature Poodle cross Cockapoo
Cocker Spaniel × Miniature Poodle, the usual pairing. The Cocker Spaniel standard is 25 to 30 lb for males and 20 to 25 lb for females, and the Miniature Poodle’s AKC figure 10 to 15 lb, so the range runs from 10 to 30 lb.
| Age | Typical | Usual range | Lightest 1 in 10 | Heaviest 1 in 10 |

Toy Poodle cross Cockapoo
Cocker Spaniel × Toy Poodle. The Toy Poodle’s AKC figure is 4 to 6 lb, about a fifth of a male Cocker’s, so this pairing spans 4 to 30 lb and the table can only bracket it.
| Age | Typical | Usual range | Lightest 1 in 10 | Heaviest 1 in 10 |
|---|---|---|---|---|
| 2 months mo | 2.04.4 | 0.4–4.30.8–9.6 | < 0.3< 0.7 | > 5.3> 11.6 |
| 3 months mo | 3.16.8 | 0.6–6.51.3–14.4 | < 0.5< 1.1 | > 7.7> 17.0 |
| 4 months mo | 4.29.2 | 0.8–8.71.8–19.2 | < 0.7< 1.5 | > 10.2> 22.5 |
| 6 months mo | 5.712.7 | 1.1–12.02.5–26.4 | < 0.9< 2.1 | > 13.9> 30.7 |
| 9 months mo | 6.815.0 | 1.3–14.13.0–31.2 | < 1.1< 2.4 | > 16.4> 36.1 |
| 12 months mo | 7.115.6 | 1.4–14.93.1–32.9 | < 1.1< 2.5 | > 17.4> 38.4 |
| 18 months mo | 7.516.6 | 1.5–15.63.3–34.4 | < 1.2< 2.7 | > 18.1> 40.0 |
| 24 months mo | 7.717.0 | 1.5–16.13.4–35.4 | < 1.3< 2.8 | > 18.6> 41.1 |
Each chart spans the whole size category, from its lightest adults to its heaviest, so its ranges run wider than a single breed’s: at least half of puppies in the category weigh within the usual range, and fewer than 1 in 10 weigh less than the lightest figure or more than the heaviest. Males and females are shown together, because the size categories are not set by sex.
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 recognises the Cockapoo. Breeder clubs exist, but no published standard from one could be traced, so this page does not use the size categories that circulate online.
Every weight range above is built from the American Kennel Club figures for its parent breeds — the Cocker Spaniel, Miniature Poodle and Toy Poodle pages on this site carry those figures 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 Cockapoos. They are the same growth curves used everywhere on this site — built from 8,754,779 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 small breeds
A Cockapoo sits in the small 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 Cockapoo get?
A Cockapoo from the usual pairing, a Cocker Spaniel and a Miniature Poodle, lands between 10 and 30 lb as an adult, because the parents’ American Kennel Club figures span that range. A Cockapoo from a Toy Poodle can be much smaller. If you do not know the pairing, enter your puppy’s age and weight into the calculator on the home page.
Is there a Cockapoo breed standard?
No kennel club recognises the Cockapoo. Breeder clubs exist, and size categories attributed to them circulate online in conflicting versions; this page does not use them because their source cannot be traced. The ranges here come from the AKC standards of the parent breeds, the Cocker Spaniel and the Poodle.
How much does a Cockapoo weigh in kg?
A Cocker Spaniel × Miniature Poodle cross lands between about 4.5 and 13.6 kg as an adult. A Cocker Spaniel × Toy Poodle cross between about 1.8 and 13.6 kg. Each table above gives every month in kilograms, with a switch to pounds.
When is a Cockapoo fully grown?
A Cockapoo is close to adult weight by about 12 months, as small-class dogs are; the last few percent can fill in over the following months.
Is my Cockapoo puppy underweight if it is below the chart?
Not necessarily. The tables show a span, and a puppy from a smaller Poodle parent will sit toward its bottom. 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 Cockapoo is a healthy weight?
Body condition tells you more than the scale. You should be able to feel the ribs under a thin layer of fat without pressing, see a waist from above and see the belly tuck up from the side. In a coated cross that check has to be done by hand.
