How to choose the right pet carrier
Updated June 2026Independently researchedNo paid placement.
The best pet carrier for you depends on your travel style, your pet’s size, and safety requirements. For air travel, you need an airline-approved hard-sided or soft-sided carrier with proper ventilation; for car rides, a crash-tested model is far safer than a basic soft bag. Measure your pet’s length and standing height before buying, and prioritize sturdy zippers, non-slip bottoms, and easy-to-clean materials.
Hard-sided vs soft-sided carriers: which is better?
Hard-sided carriers (think plastic kennels) offer the best protection for your pet and are often required for checked airline luggage. They are easy to clean, stackable, and provide solid walls that anxious pets may feel more secure behind. The trade-off: they are bulky, heavy, and harder to stow under a seat or carry over long distances. Soft-sided carriers are lighter, more flexible, and designed for cabin travel under an airline seat. They usually have mesh windows for ventilation and a quick view of your pet. Many collapse flat for storage. The downside: they offer less structural protection, can be chewed through more easily, and may not hold up well to rough handling. If you primarily fly in-cabin with a small pet, a well-reviewed soft-sided carrier is the practical choice.
How to choose an airline-approved pet carrier
Not every carrier is allowed on a plane. Airlines have strict size restrictions for under-seat carriers, typically around 18 to 20 inches long by 11 to 13 inches wide by 9 to 11 inches tall. Exceptions vary, so always check your specific airline’s current dimensions before buying. Most budget carriers require soft-sided carriers that can compress slightly to fit. Look for carriers that clearly state “airline-approved” and offer a padded shoulder strap or a carry handle that doesn’t dig into your hand. Ventilation is critical: at least two mesh sides are standard, but three sides are better for airflow. A safety tether inside that clips to your pet’s harness prevents escape when the door is opened.
Sizing your pet: measure length and height correctly
The classic mistake is buying a carrier that is too small. Your pet should be able to stand up without crouching, turn around comfortably, and lie down in a natural position. Measure from the tip of the nose to the base of the tail (body length) and from the top of the head to the floor when standing (shoulder height). Add two or three inches for comfort, but stay within airline limits if flying in-cabin. For soft-sided carriers, also consider your pet’s weight relative to the carrier’s rated capacity. Most quality carriers list a maximum weight between 12 and 20 pounds. Overstuffing stresses the seams and handles. If your pet is close to the weight limit, size up if airline rules allow, or consider a hard-sided model with a larger interior.
Ventilation, comfort, and safety features that matter
Good ventilation prevents overheating and reduces stress. Mesh panels should be well-secured and large enough to allow steady air exchange. Some carriers have roll-up covers for warmth or privacy, handy for nervous pets. Inside, a removable, machine-washable fleece or padded bed makes a huge difference in comfort, especially on long trips. Safety-wise, look for a carrier with a leash tether inside, sturdy zippers (two-way zippers can be useful), and a secure latching mechanism on the door. For car travel, the gold standard is a crash-tested carrier that has passed safety tests like those from the Center for Pet Safety. These are typically hard-sided with a reinforced structure and tie-down loops. Also check that the bottom is non-slip and that the carrier doesn’t easily shift on a car seat.
Durability and materials: what to look for in the long run
A pet carrier is an investment. For soft-sided models, look for water-resistant exterior fabrics like ripstop nylon or ballistic polyester with reinforced stitching. Zippers are the weak spot, choose carriers with heavy-duty, locking zippers that resistant to pet-prying. For hard-sided carriers, the plastic should be impact-resistant and free of sharp edges or burrs. Welded wire doors on hard carriers are far stronger than flimsy slide-bolt designs. Handles should be reinforced with webbing and padded. If you plan to travel frequently, spend a bit more on a carrier with good review longevity, owner feedback often reveals early failure points like torn mesh or broken zippers after a handful of trips.
Frequently asked questions
Can I take a pet carrier on a plane?
Yes, but you must use an airline-approved carrier that fits under the seat in front of you. Most carriers marketed as travel- or airline-approved will list their dimensions and weight limits. Double-check your airline’s latest policy because rules change frequently.
How do I measure my pet for a carrier?
Measure your pet’s body length from nose to tail base and their standing height from floor to top of head. Add a couple of inches for wiggle room. Your pet should be able to stand, turn around, and lie flat inside the carrier.
What is the best material for a pet carrier?
For airline cabin travel, soft-sided carriers made from water-resistant nylon or polyester with reinforced seams are ideal. For car travel or checked baggage, hard-sided plastic carriers offer better protection. Avoid carriers with thin fabric that can be easily clawed or chewed through.
Are wheeled pet carriers safe?
Wheeled carriers are convenient in airports, but they can be unstable on uneven surfaces and may tip over if your pet moves suddenly. They are usually not crash-tested for car use and often lack a proper tether. Use them only for very small pets on smooth floors, and never leave your pet unattended in a wheeled carrier.
How do I clean a pet carrier?
Most soft-sided carriers have removable, machine-washable liners or beds. Spot-clean the outer fabric with mild soap and water. Hard-sided carriers can be wiped down with disinfectant wipes or a bleach solution. Let everything dry thoroughly to prevent mold and odors.
Can I use a carrier for car travel without strapping it in?
You should always secure a pet carrier in a car. Many soft-sided carriers can be belted in using the seatbelt through the handle or built-in loops. Hard-sided carriers require tie-down straps or a wheeled crate that fits into the cargo area. An unsecured carrier is a projectile during a sudden stop.
