Cat Bed Size Guide: How to Measure for a Comfortable Fit

What size cat bed should you buy? Choose a bed whose usable sleeping area accommodates your cat in their usual resting position, with room to turn and settle. Measure your cat while relaxed, compare those measurements with the bed's interior space, and check any stated weight guidance. A size label such as “Small” or “Large” is not enough on its own.

This guide from The Pet Edit explains what to measure, which dimensions to check, and how to compare the cat beds available at thepetedithome.com.

1. Start with how your cat actually sleeps

Watch a few ordinary naps before choosing a bed. Does your cat curl into a tight circle, lie on one side, or stretch across a cushion? Measure the space they use in that position rather than choosing only by breed or body weight.

• Curled-up sleepers: compare the width of their relaxed curl with the bed's usable inner diameter or sleeping area.
• Side sleepers and stretchers: check both length and width. A round bed's advertised diameter may include a raised rim, leaving a smaller space in the middle.
• Cats that change positions: allow for their more extended resting position, and check that the bed offers room to turn.

2. Measure your cat without disturbing their rest

Use a tape measure beside your cat while they are resting comfortably; there is no need to hold them in a particular pose. Note the length and width of the area their body occupies. If they are sleeping on a favorite blanket, you can also measure the patch they use after they move away.

Write down those measurements in the same units as the product listing. For conversion, 1 inch equals 2.54 centimeters. Keep your cat's current weight handy as a separate check, but do not use it as a substitute for measuring their resting space.

3. Check sleeping space, not just the outside dimensions

A bed's listed dimensions may describe the overall product. Padded sides, raised edges and a covered section can reduce the usable space inside. For a semi-enclosed bed, also consider the entrance and the space under the cover.

If a listing does not specify interior measurements, ask before ordering. Send your cat's resting measurements and the exact product and size you are considering to order@thepetedithome.com. Ask about the usable sleeping area and entrance dimensions rather than assuming the full listed footprint is available inside.

4. Compare the size options on the actual product page

Size names are not standardized across different bed designs. A “Large” round bed and a “Large” semi-enclosed bed can have different shapes and usable spaces.

Semi-enclosed bed: compare length, width and height

The Semi-Enclosed Plush Pet Bed for Cats and Small Dogs currently lists these options:

• Small: 20.9 × 17.7 × 9.8 inches; listed for pets up to 11 lb.
• Large: 25.6 × 20.9 × 9.8 inches; listed for pets up to 33 lb.

These are the published product dimensions and weight guidelines, not confirmed interior measurements. The Large option adds length and width while keeping the same listed height. Check the entrance and usable interior if your cat needs more headroom or likes to stretch.

For an open round alternative, explore the Round Faux-Plush Pet Bed for Cats and Small Dogs. Compare its usable center with your cat's curled and extended resting measurements before selecting a size.

Product options can change. Check the current product page and confirm any missing measurements before purchasing.

5. Choose a location your cat is comfortable using

Fit is only part of the decision. Cats Protection recommends a comfortable sleeping surface and a quiet, private place to rest. A familiar blanket can also help a new bed feel more familiar. See its guide to choosing a cat bed for more on comfort and placement.

Before ordering, measure the floor space where the bed will go and make sure its entrance will remain accessible. If you add a blanket, remember that it takes up some of the sleeping space you measured.

Cat bed sizing checklist

• I have measured my cat's usual resting length and width.
• I have checked the usable interior, rather than relying only on the outside footprint.
• I have considered the entrance, cover and raised sides.
• I have checked the product's stated weight guidance.
• I have measured the intended location and checked the current return policy.

Frequently asked questions

Can I choose a cat bed by weight alone?

No. Weight guidance is one check, but cats with similar weights can have different body lengths and sleeping positions. Compare your cat's resting measurements with the usable sleeping area as well.

Should I size up if my cat is between two sizes?

Compare the actual interiors first. The larger option may be more suitable if the smaller one restricts your cat's usual resting position, but a larger label does not guarantee the right entrance, height or shape.

Is a round or semi-enclosed bed better?

Choose around your cat's habits and the available space. A round bed offers an open resting area, while a semi-enclosed design provides a more covered space. Our elevated vs enclosed pet bed guide explains the differences between bed styles.

What if my cat does not use the new bed?

Review its location and comfort, give your cat time to approach it, and try a familiar blanket if there is enough room. No bed can guarantee that a cat will choose it over their existing favorite spot.
