Dog Bed Size Calculator
How your dog sleeps matters as much as how big it is. Enter its length and sleeping style to get the bed size, the foam to look for, and beds that fit.
XL
For seniors and large breeds: choose solid support foam, not shredded fill — at least about 4 inches thick, and thicker (6–7 in) for giant or very heavy dogs so they don't sink to the floor. A low entry helps stiff joints. See our orthopedic bed guide.
Beds in this size
Sizes are labelled differently by each brand — check the bed's length in inches against the number above.
How the calculator works
It starts from your dog's length (nose to base of the tail) and adds room for how it sleeps: about 6 inches for dogs that curl up, 10 inches for dogs that stretch out, and 14 inches for sprawlers. It then matches the result to common bed lengths (Small ~24 in, Medium ~30 in, Large ~36 in, XL ~42 in, XXL ~48 in, Jumbo 54 in+). From weight, it uses typical brand sizing ranges; with both, it takes the larger answer.
