Pet Carrier Fit Finder
Carrier shopping is full of vague "small / medium / large" labels. Enter your dog or cat’s weight and this points you at the right carrier type, sized to real manufacturer weight ratings from our reviewed picks, so you can stop guessing whether the one in your cart actually fits. It also flags what changes for senior, injured, or anxious pets.
The interactive finder runs with JavaScript on. The carrier-by-weight reference is right below either way.
Which carrier by weight, and where the numbers come from
The finder maps your pet’s weight to a carrier type using manufacturer-published weight ratings from the picks in our cat carrier guide anddog carrier and crate guide. Nothing here is a made-up spec.
Cats
| Cat weight | Carrier type |
|---|---|
| Up to 12 lb | Soft- or hard-sided carrier rated to weight (crash-tested and budget options both fit) |
| Over 12 lb | Larger hard-shell kennel, sized above the 12 lb rating of the popular soft carriers |
Dogs
| Dog weight | Carrier type |
|---|---|
| Up to 16 lb | Soft-sided travel carrier, or a small crate |
| 16-22 lb | Large soft-sided carrier, or a small crate |
| Up to 30 lb | Small collapsible crate |
| 30-50 lb | Medium collapsible crate |
| 50-70 lb | Intermediate collapsible crate |
| 70-90 lb | Large crate |
| Over 90 lb | Oversize crate, sized by published height and length; measure and confirm |
A weight rating is a starting point, not a guarantee of fit. Measure your pet and check the carrier’s stated interior height and length so it can stand and turn around. A carrier is containment, not crash protection unless it says crash-tested.

Frequently asked questions
How do I know what size carrier my dog or cat needs?
Match your pet's weight to the carrier's manufacturer-published weight rating, then measure your pet against its stated interior size so it can stand up and turn around. Weight ratings alone don't guarantee fit, especially for tall or long dogs, so this finder gives you the right type and specific rated picks, and you confirm the dimensions against your own pet.
My cat is over 12 lb. What carrier fits?
The popular crash-tested soft cat carriers top out around 12 lb, so a heavier cat needs a larger hard-shell kennel with a published capacity above that. Size up and measure; a roomy dual-door or double kennel is usually the fit, and a hard shell is safer in the car than a soft carrier stretched past its rating.
Is a carrier the same as crash protection?
No. A carrier is containment; it keeps a pet from bolting or roaming the vehicle. It is only crash protection if the manufacturer specifically states it is crash-tested (for example by the Center for Pet Safety). For car travel, prefer a crash-tested option and anchor it, rather than assuming any carrier protects in a collision.
What about senior, injured, or anxious pets?
Choose a top-load carrier so you can lift the pet in from above instead of coaxing a stiff or panicked animal through a front door, and plan a ramp or a two-person lift for loading a heavy or mobility-limited dog. A covered, hard-sided carrier also reduces the visual stress that makes an anxious pet bolt.
