Whippet size chart: crate, harness & collar
What the published charts say for a Whippet, across 19 harnesses, 6 crates and 7 collars. Every answer says how it was reached, and none of them replaces measuring your dog.

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.

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 Whippet
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 Whippet
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 Whippet: 21.7 to 23.6 in chest, 15.7 to 17.7 in neck (TARIGS, "Size table for different breeds").
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 Whippet size chart
Where to put the tape. Leave a box empty and the answers that need it say so, rather than guessing.
Enter a measurement above to see what each maker's chart says.
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 Whippet?
- On the charts published by their makers, a Whippet comes out at Julius-K9 IDC Powerharness Mini or 0, Ruffwear Front Range Harness XS or S, Ruffwear Flagline Harness XS or S (by published chest girth), with 19 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 Whippet?
- By the makers' own weight guidance, a Whippet comes out at MidWest Homes for Pets iCrate Single Door Folding Dog Crate 24-inch or 30-inch, MidWest Homes for Pets LifeStages Single Door Dog Crate 24-inch or 30-inch, Petmate Sky Kennel 28" or 32". 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 Whippet get?
- An adult Whippet is 19–22 in tall at the shoulder for males and 18–21 in for females, 25–40 lb. Published sizing charts give a chest girth of 21.7–23.6 in and a neck of 15.7–17.7 in. These are breed-standard ranges, not your dog: individual dogs sit outside them. Measure your dog.
