How to Measure Your Dog for the Perfect Bed Size

The first step is to measure your dog from nose to tail while they are standing. This will give you a good idea of how long their body is and what type of bed they will need. If your dog is less than 20 inches long, they will need a small bed; if they are between 20 and 30 inches long, they will need a medium-sized bed; and if they are over 30 inches long, they will need a large-sized bed.

The second step is to measure your dog from their shoulders to the ground while they are standing. This will give you an idea of how tall they are and how much space they will need in a bed. If your dog is less than 12 inches tall, they will need a small bed; if they are between 12 and 18 inches tall, they will need a medium-sized bed; and if they are over 18 inches tall, they will need a large-sized bed.

Paw-fection! Now that you know how to measure your dog for their new bed, it’s time to shop! There are tons of great beds on the market, so take your time and find one that suits both your style and your pup’s needs. And if you’re still not sure which size is best, remember that you can always ask a pet store employee or veterinarian for help. They’re paw-fessionals, after all!

The following shows the dimensions of various beds and is a great starting point for finding the right one for your pup. The following is a size guide and gives standard size examples in length x width x height:

Keep in mind that dogs like to curl up when they sleep, so a smaller size dog bed might actually be more comfortable for them than a larger one. If possible, it’s always best to see the bed in person before making a purchase so you can get a better sense of how big (or small) it really is for your ideal size.

If that’s not possible, read customer reviews before pulling the trigger on any purchase. People are often quick to leave negative reviews if a product wasn’t what they were expecting, so reading through those can be helpful in getting an accurate sense of the proper size and fit of a particular bed.

Size Matters – But How Much?

The first thing you need to consider when purchasing the perfect size bed is, of course, size. But it’s not as simple as just buying the biggest bed you can find. You also need to consider your dog’s weight, height, and sleeping habits to determine the proper bed size. Let’s break it down:

  • Body Weight: Heavier dogs will need a sturdier, more supportive bed that can withstand some wear and tear. Conversely, smaller dogs or those with an average weight range can get by with a thinner, less bulky bed. The bottom line is that you want your dog to be comfortable – not cramped up or too spread out.
  • Height in Inches: This one is pretty straightforward – simply measure your dog from the top of their head to the base of their tail. You’ll want to look for a bed that gives them plenty of space to stretch out (bonus points if it has raised sides for them to rest their head on).
  • Sleeping habits: Does your dog like to curl up in a ball when they sleep? Or do they sprawl out? This will give you a good idea of how much space they’ll need in their bed. If your dog is active, consider a bed with raised sides so they don’t accidentally roll off in the middle of the night.

Think About Their Age and Health

Puppies grow quickly, so if you’re shopping for a puppy bed, be sure to take their age into account and purchase a bed that will fit them once they’re fully grown. If your dog is getting up there in years or has any health conditions that might limit their mobility (like arthritis), you’ll want to get a lower-profile bed that’s easier for them to get in and out of.

Shape Matters Too!

Besides size, you’ll also want to take into account the shape of the bed when making your final selection. Some dogs prefer beds that are more closed in and cozy, while others like ones that give them plenty of room to stretch out.

Think about your dog’s sleeping habits and try to select a bed that will accommodate those. For example, if your dog likes to curl up into a ball when sleeping, a round or oval-shaped bed would be best. But if they tend to spread out or sleep on their side, something more rectangular would be better suited for them.

Bed Materials 101

Now that you know what size bed you need, it’s time to think about materials. The most popular options are memory foam, orthopedic foam, pillow top beds, bolster beds and cooling beds. Not sure which one is right for your pup? Here’s a quick rundown of each type:

  • Memory foam: This type of bed conforms to your dog’s body shape and provides joint support. It’s ideal for older dogs or those with arthritis or hip dysplasia.
  • Orthopedic foam: Similar to memory foam but with an added layer of cushioning; this type of bed is also great for older dogs or those with joint issues.
  • Pillow top beds: These have a soft outer layer filled with either fiber or feathers; they’re often used as crate mats or car seat covers but can also make great standalone beds. Just be aware that pillow top beds are not as durable as other types and may need to be replaced more frequently.
  • Bolster beds: These beds have raised sides (or “bolsters”) that provide support and security for your dog while they sleep; they’re perfect for dogs who like to curl up when they snooze.
  • Cooling beds: These feature gel-infused memory foam or cooling gel inserts that help regulate your dog’s body temperature; they’re ideal for hot summer days or pups who overheat at night.

Choosing the Right Fabric Material

Once you’ve decided on the type of bed you want, it’s time to think about fabrics. The most popular options are cotton/polyester blend, microfiber, denim, corduroy, and fleece; each has its own unique benefits. Here’s a quick overview:

  • Cotton/polyester blend: This fabric is durable and easy-to-clean; it’s ideal for homes with multiple pets or pups who are prone to accidents.
  • Microfiber: This fabric is soft on your pup’s skin; it’s ideal for small dogs or those with sensitive skin
  • Denim: This fabric is sturdy and resistant to wear and tear; it’s ideal for large breeds or pups who like to chew on their bedding
  • Corduroy: This fabric is stylish and classic; it’s ideal for any type of home décor.
  • Fleece: This fabric is cozy and warm; it’s ideal for cold winter nights or pups who get chilled easily


How do I know what size dog bed to get?

You should get a dog bed that is big enough for the dog to stretch out on, but not so big that the dog can easily move or fall off of the bed.

Should a dog bed be bigger than the dog?

No, a dog bed should not be bigger than the dog. A too-large bed can be dangerous for a small dog and may make it difficult for the dog to stay warm.

Should a dog bed be snug?

A snug bed is good for dogs who like to curl up when they sleep. For most dogs, however, a slightly larger bed is better so they can spread out.

Should a dog bed be the same size as the crate?

Yes, you should get a dog bed that is the same size as the crate. A too-small bed in a large crate can make the crate feel cramped and uncomfortable for the dog.

How often should I replace my dog’s bed?

You should replace your dog’s bed every 6 to 12 months, depending on how much wear and tear it gets. You may also need to replace the bed sooner if your dog has an accident or sheds excessively.

Is it OK to move a dog’s bed around?

Yes, it is fine to move a dog’s bed around. Just be sure to put it back in the same spot each night so the dog can find it easily.

Is my dog bed big enough?

A good rule of thumb is that the bed should be big enough for the dog to stretch out comfortably.

Do dogs like their beds?

Yes, most dogs like having their own bed. A bed gives the dog a place to feel safe and secure, and it can help reduce anxiety levels.
