Maltipoo size chart: crate, harness & collar
What the published charts say for a Maltipoo, across 19 harnesses, 6 crates and 7 collars. Every answer says how it was reached, and none of them replaces measuring your dog.
Needs review: NEEDS REVIEW: the North American Maltipoo/Maltepoo Club & Registry site did not respond and no published club size standard could be opened; PetMD used as a clearly named fallback. (Third-party sites claim the National Maltipoo Club / Maltipoo Club of America standard is 5-12 lb; not verified.)
Note: PetMD FAQ on the same page says "about 10-20 pounds"; the intro figure 5-20 lb is used.
Note: No sex split; copied to both sexes.
Worth checking: No breed club or registry publishes a size standard for this cross, so these figures come from PetMD Maltipoo breed page (reviewed by Jennifer Coates, DVM; updated Jul 16, 2026).

No published chest or neck girth was found for this breed. Girth is never worked out from weight or height here, so the tables below fall back to weight where a maker prints it, and say so.
These are published breed figures, not your dog. Measure your dog — chest girth for a harness, neck for a collar, length and height for a crate.

Rows marked “by weight only” had no published girth to work from, so the maker’s weight bands were used. That is the weaker route, and two dogs of the same weight can need different sizes.
Where a size reads as a span, the breed’s published range reaches across that many of the maker’s sizes. This site shows the span rather than choosing one for you.

Every crate row above is by the maker’s weight guidance, because no published body length exists per breed. A crate is sized on the body: use the calculator below with your own measurements.

Puppy?
Size for the adult and use a divider. A crate bought to fit a puppy is outgrown in weeks, and a crate with a spare end stops working as a den. Buy the adult size and move the divider back as the dog grows. A harness or collar is the opposite: buy for the dog you have now, because adult-sized straps slip on a puppy.
Is your dog a mix?
Mixes vary a lot. Measure your dog. A breed figure describes a published standard, and a mix is not held to one. Two dogs from the same litter can land two sizes apart on the same chart.
Measure your Maltipoo
The tables above start from a published breed range. This starts from your dog. Crates need a body length and a standing height, plus 4 in of room.
Size your Maltipoo
Enter what you have measured. Every answer below is the maker’s own published range against your number — a starting point, not a fitting.
No chest or neck girth is published for the Maltipoo, so there is nothing to compare against here.
Measure your dog and enter it. A published range is a range: the boxes below stay empty because the middle of a range is a number nobody published. Full Maltipoo size chart

Sizes come from each maker’s own published chart. Check the maker’s current chart before you buy: charts change, and nothing here is a guarantee of fit.
Common questions
- What size harness for a Maltipoo?
- On the charts published by their makers, a Maltipoo comes out at Julius-K9 IDC Powerharness Baby1 to Mini (4 sizes), Kurgo Tru-Fit Smart Harness (quick release) X-Small or Small, PetSafe Easy Walk Harness Petite to Small / Medium (4 sizes) (by weight only, which is the weaker route), with 7 of 19 charts giving a size. Size labels are not comparable between brands, so read the range rather than the letter. Measure your dog's chest girth at the widest part of the rib cage and check it against the maker's own chart before you buy.
- What size crate for a Maltipoo?
- By the makers' own weight guidance, a Maltipoo comes out at MidWest Homes for Pets iCrate Single Door Folding Dog Crate 18-inch to 24-inch (3 sizes), MidWest Homes for Pets LifeStages Single Door Dog Crate 22-inch or 24-inch, Petmate Sky Kennel 21". Weight is the rougher route: a crate is sized on the body. Measure your dog from the nose to the base of the tail and from the floor to the top of the head while standing, add 4 inches to each, and compare that with the crate's interior, not its outside.
- How big does a Maltipoo get?
- An adult Maltipoo is 8–14 in tall at the shoulder, 5–20 lb. No published chest or neck girth was found for this breed. These are breed-standard ranges, not your dog: individual dogs sit outside them. Measure your dog.
