How to Measure Your Dog for a Bed
Share
A few quiet observations can tell you more than a breed chart. Measure the space your dog naturally uses, then compare it with the bed's flat sleeping area.

Begin with a familiar resting place
Notice how your dog settles at home. They may curl into a small circle, stretch along one side, or extend their legs across the floor. Watch on more than one occasion if their position changes. There is no need to move their legs or coax them into a pose for the tape measure.
ANBERSO's size guidance starts with the dog's stretched resting position. A bed chosen only around the smallest curled pose can feel quite different when that same dog lies long or turns around.
Take two measurements
- While your dog is comfortably stretched out, measure from nose to rump along the direction they lie. Exclude the tail.
- Measure the widest part of the space they occupy across that pose, including legs that usually extend to the side.
- Record both measurements in centimetres or inches, and choose the same unit in the Size Finder.
These measurements describe a resting footprint, not a breed-based size. If two dogs share a bed, observe the space they actually use together.
Look beyond the outside dimensions
The overall dimensions tell you how much floor space the bed needs. The flat sleeping area is the central space where your dog can lie completely flat. You need both measurements: one for your dog, one for your room.
A flat cover leaves the top open. A bolster cover has a raised edge on three sides where a dog can rest their chin or lean their body. That edge is part of the resting space, while the central flat area is smaller than the bed's overall footprint. Compare your dog's length and width with the flat sleeping area of the style you are considering. Then check the overall dimensions against the intended place in your home.
For current bed dimensions and available sizes, use the ANBERSO Global Size Guide.

If two sizes fit
Start with the smallest size whose flat sleeping area accommodates the stretched pose you measured. Then compare the next roomier size if your dog often changes direction or seems to use more space at other times. Check the larger bed in the actual room too, including nearby furniture and walkways.
The larger choice is an option, not an automatic answer. A change from flat to bolster deserves a fresh sleeping-area comparison even when the size name stays the same.
When you have a size and shape in mind, explore the Royal Bed Complete Sets. Each set combines a bed base with a cover; check the current product page for its included parts and size options.
A final check
- Did you measure a relaxed position your dog uses naturally?
- Do both the length and width fit the flat sleeping area of the cover style you chose?
- Does the bed's overall footprint fit its place in your home?
