Queen or King for a Couple with a Dog in Bed?
On a queen, two adults each get 30 inches of width. Add a dog and your width drops fast. Here is the math by dog size.
Width left per adult when the dog joins
Average sleeping-position widths from veterinary and bed-product sizing data. A "sleeping" dog typically takes 1.5 to 2 times its standing width because of curling and spread.
| Dog | Dog width when sleeping | Queen: width per adult | King: width per adult |
|---|---|---|---|
| No dog (baseline) | 0 in | 30 in | 38 in |
| Small dog (under 25 lbs, e.g. Yorkie, Pug, Cavalier) | 18 in | 21 in | 29 in |
| Medium dog (25 to 50 lbs, e.g. Beagle, Spaniel, Border Collie) | 24 in | 18 in | 26 in |
| Large dog (50 to 80 lbs, e.g. Lab, Golden, Boxer) | 30 in | 15 in | 23 in |
| Extra large dog (80 lbs+, e.g. German Shepherd, Bernese, Great Dane) | 36 in | 12 in | 20 in |
Reference width: a standard twin mattress is 38 inches wide. That is the width one adult uses to sleep comfortably alone. Anything below 24 inches per adult means significantly less than half a twin per person.
When to size up to king
Medium dog or bigger, sharing nightly
If a Beagle-size or larger dog sleeps in bed nightly, the king is typically worth the upgrade. On a queen, each adult ends up with less than 24 inches, which is narrower than a recliner seat.
Small dog, infrequent
A 15 lb dog that joins occasionally still leaves you with 24 inches per adult on a queen. Manageable, especially if the dog sleeps at the foot rather than between you.
Two dogs
A queen with two dogs leaves no usable width for adults. Most couples with two dogs report only the king is workable. Even better: a king with dog bedding at the foot to keep both dogs off the sleeping surface.
A note on co-sleeping with pets
Co-sleeping with pets is generally safe for healthy adults but may reduce sleep quality. The Mayo Clinic Center for Sleep Medicine has reported that sharing a bed with a pet may modestly reduce sleep efficiency. People with allergies, asthma, or compromised immune systems should consult a clinician about pet co-sleeping. Source: Mayo Clinic.
