Goldendoodle Weight Calculator: Adult Size by Poodle Parent and Age

Your Goldendoodle's adult weight depends mostly on the Poodle parent. Petful lists miniatures at 20 to 35 pounds, mediums at 35 to 50 and standards at 50 to 90. This Goldendoodle weight calculator covers the size bands, weight by age, the formula that fails, and what each size costs to feed.

Goldendoodle size chart: four sizes, two sources

A Goldendoodle falls into one of four size bands, set by the Poodle parent. No kennel club writes a Goldendoodle standard. Every chart is a breeder convention. Petful's Goldendoodle size guide, published July 14, 2026, gives these bands.

Size	Adult weight	Shoulder height	Poodle parent
Petite ("teacup")	15-25 lb	11-14 in	Toy or small miniature
Mini	20-35 lb	14-17 in	Miniature
Medium	35-50 lb	17-20 in	Small standard
Standard	50-90 lb	20-24 in	Standard

Petful notes that "teacup" is a marketing term and not an official category. Wikipedia's Goldendoodle entry draws the lines in slightly different places.

Sources do not agree. Our Goldendoodle price guide quotes Spot Pet Insurance at 40 to 50 pounds for a standard, below both charts above. Treat every band as a range of likely outcomes. The breeder's parent weights are better evidence than any chart.

Goldendoodle weight calculator: start with the parents

The most useful Goldendoodle weight calculator uses both parents' adult weights. A cross lands between its parents, so averaging them gives a first guess. PetBudget's breed data lists these parent weights.

Parent	Weight range	Midpoint
Golden Retriever	55-75 lb	65 lb
Toy Poodle	4-6 lb	5 lb
Miniature Poodle	15-17 lb	16 lb
Standard Poodle	40-70 lb	55 lb

Average the Golden's 65 pounds with each Poodle's midpoint. A Toy Poodle cross comes to 35 pounds, a Miniature Poodle cross to 40 pounds and a Standard Poodle cross to 60 pounds. A 35-pound result tops the mini band, 40 pounds is a medium and 60 pounds is a standard. The Toy Poodle result runs high, since Petful puts toy crosses at 15 to 25 pounds.

This is PetBudget arithmetic, not a validated formula. Use it to sanity-check a breeder's claim, not to predict a single dog.

Goldendoodle growth chart: weight by age

A standard Goldendoodle roughly quadruples its weight between 8 weeks and 6 months. Petful gives weights at three ages for each size.

Size	8 weeks	3 months	6 months	Near-final weight
Mini (adult 15-35 lb)	5-6 lb	9-12 lb	17-22 lb	11-13 months
Medium (adult 30-45 lb)	8-10 lb	18-24 lb	28-36 lb	12-14 months
Standard (adult 45-90 lb)	10-14 lb	22-30 lb	40-50 lb	Still filling out at 14-18 months

The adult ranges in this table differ from the size chart above. Petful uses 15 to 35 pounds for a mini here and 20 to 35 above. Watch the pattern of growth more than the labels.

Why the simple puppy formula overshoots

The common puppy formula multiplies current weight over age in weeks by 52. Our puppy weight calculator guide explains it. It assumes steady growth all year, and Goldendoodles grow fast early and slow later.

Run Petful's own midpoints through it and the answers run high:

Puppy	Formula result	Petful adult range
Mini, 8 weeks (5.5 lb)	36 lb	15-35 lb
Mini, 3 months (10.5 lb)	42 lb	15-35 lb
Mini, 6 months (19.5 lb)	39 lb	15-35 lb
Standard, 3 months (26 lb)	104 lb	45-90 lb
Standard, 6 months (45 lb)	90 lb	45-90 lb

Every mini result lands above the top of the mini range. The standard result at 3 months is 14 pounds over the top of its range. The formula does better at 6 months, when growth has slowed.

How big will my Goldendoodle get? Five steps

You can narrow the estimate in five steps:

1. Get the parents' adult weights from the breeder, in writing.
2. Find the Poodle parent's variety: toy, miniature or standard.
3. Match it to a band in the Petful table above.
4. Weigh the puppy weekly on the same scale.
5. Compare to the age table and expect a standard to keep growing past a year.

Generation matters less for size than for coat. Petful lists an F1 cross (Golden Retriever by Poodle) as wavy and varied by litter. An F1b (F1 bred back to a Poodle) is curlier and more consistent, and an F2 is highly variable. Petful ties size to the Poodle parent, not the generation.

When do Goldendoodles stop growing?

Small Goldendoodles finish near the first birthday, and standards take longer. Petful says petite and mini dogs are essentially done by 11 to 13 months. Mediums reach full height by about 12 months and final weight by about 14 months. Standards reach adult height near 14 months, and muscle and weight may build until 18 months.

The Elanco puppy growth chart fits that pattern. It puts medium breeds at about 1 year and large breeds at 14 to 18 months.

Male and female Goldendoodle weight

Male Goldendoodles run heavier than females. Wikipedia lists males at about 22 inches and 55 to 75 pounds, and females at about 20 inches and 40 to 65 pounds. That gap is up to 15 pounds on the same cross.

Use the female range when a breeder quotes a litter average. A male from the same litter can land a size band higher. Sex also shifts the food bill by roughly $100 a year at these weights.

Bigger Goldendoodles cost more to feed

A 90-pound Goldendoodle costs three times as much to feed as a 20-pound one. The table applies PetBudget's food formula to a neutered adult. It uses the Merck Veterinary Manual factor of 1.6 times resting energy, plus 10% treats, at $3.99 a kilogram.

Adult weight	Calories a day	Food a year	Cups a day
20 lb	644	$260	1.7
35 lb	980	$396	2.5
50 lb	1,280	$518	3.3
70 lb	1,648	$666	4.2
90 lb	1,990	$805	5.1

The cups assume 388 calories a cup, a typical value. Check your bag's label. PetBudget's parent models use the intact factor of 1.8. They put food at $249 a year for a Miniature Poodle, $627 for a Standard Poodle and $711 for a Golden Retriever. Our dog feeding guide shows the full method.

Food is only one line. Our Goldendoodle price guide builds the whole budget from the Standard Poodle model. The Standard Poodle and Golden Retriever pages show each parent's costs.

Questions to ask the breeder about size

A breeder who sells by size band should back it with numbers. Ask these questions before you pay a deposit:

1. What do both parents weigh as adults, and when were they weighed?
2. Is the Poodle parent a toy, a miniature or a standard?
3. How much did adult dogs from earlier litters weigh?
4. Is the size band a guess or a guarantee, and is that in the contract?
5. Which generation is the cross: F1, F1b, F2 or multigen?

Vague answers are a warning. A seller who says "teacup" and cannot name the parents' weights is selling a label.

Is your Goldendoodle at a healthy weight?

Weight alone does not tell you if a Goldendoodle is healthy, because the healthy range spans 20 to 90 pounds. Check body condition instead. You should feel the ribs under a thin layer of fat, and see a waist from above.

Owners often misjudge it. The Association for Pet Obesity Prevention reports that 59% of U.S. dogs were overweight or obese in 2022. In its 2023 owner survey, only 17% of dog owners called their own dog overweight. Another 84% said their dog was ideal or healthy.

Thin is not automatically safe either. The Dog Aging Project study below found higher bloat odds in dogs with a low body condition score. Aim for the middle of the scale and ask your vet to score your dog at each visit.

Size, bloat and other health risks

Bigger Goldendoodles carry more bloat risk. A 2026 Dog Aging Project study in the Journal of the American Veterinary Medical Association drew on 47,444 enrolled dogs. Odds of bloat were higher in purebreds, males, dogs over 40 kilograms (88 pounds) and dogs with a low body condition score.

The study also called one result novel. Poodles had the highest occurrence of bloat of any breed, and Poodle mixes also showed higher odds. It found no link to diet type or the number of meals a day. Lifetime prevalence overall was 0.23%.

Wikipedia adds that Goldendoodles are prone to megaesophagus, a swallowing disorder. Ask your vet about a preventive stomach tack at spay or neuter. Our emergency vet cost guide shows what a bloat emergency costs.
