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 Labrador Retriever
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 Labrador Retriever
Enter what you have measured. Every answer below is the maker’s own published range against your number — a starting point, not a fitting.
Published range for the Labrador Retriever: 28 to 36 in chest, 17 to 23 in neck (Hund & Shore, "Dog Collar & Harness Size Chart by Breed").
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 Labrador Retriever 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 Labrador Retriever?
- On the charts published by their makers, a Labrador Retriever comes out at Julius-K9 IDC Powerharness 0 to 3 (4 sizes), Ruffwear Front Range Harness M or L/XL, Ruffwear Flagline Harness M or L/XL (by published chest girth), with 18 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 Labrador Retriever?
- By the makers' own weight guidance, a Labrador Retriever comes out at MidWest Homes for Pets iCrate Single Door Folding Dog Crate 36-inch or 42-inch, MidWest Homes for Pets LifeStages Single Door Dog Crate 36-inch or 42-inch, Petmate Sky Kennel 36" or 40". 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 Labrador Retriever get?
- An adult Labrador Retriever is 22.5–24.5 in tall at the shoulder for males and 21.5–23.5 in for females, 65–80 lb for males and 55–70 lb for females. Published sizing charts give a chest girth of 28–36 in and a neck of 17–23 in. These are breed-standard ranges, not your dog: individual dogs sit outside them. Measure your dog.
