FAQ

Pet Size & Fit Questions

Can this pet size calculator replace a product size chart?
No. Harnesses, carriers, beds, ramps, and stairs use different patterns and dimensions. Use this finder to prepare the right measurements, then compare them with the exact product chart and usable interior dimensions before buying.
How do I measure my dog for a harness?
Measure the lower neck where the harness neckline will sit, the widest part of the rib cage while your dog stands, and body length only when the chart asks for it. Keep the tape flat without pulling it tight, then compare every required measurement with one product chart.
What size dog bed should I choose?
Measure the natural sleeping length and width, then compare the result with the bed's clear interior sleep surface. Thick bolsters and raised edges reduce usable room, so the outside product dimensions can be misleading.
How does the IATA cargo crate formula work?
Using the standard A, B, C, and D pet measurements, the starting interior length is A plus half of B, width is twice C, and height is D. Round up, then confirm current IATA and operating-airline requirements for the exact trip.
Can this finder confirm an in-cabin pet carrier?
No. Cabin limits depend on the operating airline, route, aircraft, seat, fare, reservation availability, and current policy. Ask the airline for the maximum carrier exterior dimensions and pet requirements before buying or traveling.
How long should a dog ramp be?
Ramp length depends on the access height and the incline you are comparing. Gentler angles need more floor space. Use the mobility mode to compare 18, 22, and 25 degree reference runs, then consider grip, width, edge protection, stability, and your pet's real movement.
