Frequently Asked Questions
Should a crate be exact or a little larger?
Start with a size that lets the dog stand, turn, and lie down comfortably. A crate that is too small is restrictive; one that is too large can feel less secure and may make house-training harder.
What if I only know my dog's weight?
Weight alone is enough for a rough baseline, but measurements make the result much more accurate. Use the weight-based size class as a starting point and then confirm the internal dimensions against the dog you actually have.
Is a travel crate the same as a home crate?
Not always. Travel and airline use can require more strict sizing, ventilation, or construction rules. Use this estimate as a planning tool and check the rules for the exact carrier or airline before you buy.
Do puppies need a new crate size as they grow?
Yes. Puppies can outgrow crates quickly. Recheck the measurements whenever weight or body length changes enough that the current crate starts to feel tight.
