How Big Should Outdoor Dog Kennels Be?

by Dakota Storage Buildings, on July 26, 2022


Choosing the right size outdoor dog kennel is crucial for not only their happiness but also their health. But which size do you need? While there are several options out there, typically, the best move you can make is to go bigger than you think. Let’s discuss what considerations you should make when investing in an outdoor kennel for your dog.

Dog Kennel Sizes

In general, this table can help you choose the right size outdoor kennel for your dog.

Dog Weight

Kennel Size (inches)

18 – 24 pounds

24″ (length) by 18″ (width)

26 – 40 pounds

30″ (length) by 22″ (width)

41-70 pounds

36″ (length) by 26″ (width)

71-90 pounds

42″ (length) by 34″ (width)

91-110 pounds

48″ (length) by 36″ (width)

110-205 pounds

54″ (length) by 40″ (width)


So if you’re wondering how big your outdoor dog kennel size should be, you need to consider their size. If your dog weighs 40 pounds, you’ll want an outdoor kennel that measures 30”x22”. If you’re unsure what size kennel to get, it’s best if you go up a size. In the previous example, since the dog would be at the upper end of that range, you could certainly go up to the 36”x26” kennel.

Factors to Consider for Dog Kennel

The two most important factors are the following:

  • Length of the dog
  • Height of the dog

A dog’s size is obviously the biggest concern when determining how big your kennel size should be. However, you’ll also want to consider your dog’s energy level, abilities, and average time spent in the kennel. A dog who spends a lot of time in a kennel will need more room to run. In most cases, the longer the kennel, the better. Your dog will appreciate the space to run and play.

Their height is also a big part of their size. Ensure your new kennel is tall enough for your dog to stand on its hind legs without hitting its head. You’ll also want to provide a sleeping area that’s enclosed. It’ll need to be large enough for your dog to sleep however they want. However, dogs like a home that feels like a den, so a cozy sleeping area within the kennel is a great idea.

For more guidance, the American Society for the Prevention of Cruelty to Animals recommends that dog owners use a kennel at least 10 feet by 10 feet or 5 feet by 15 feet. Making a kennel longer than 15 feet helps with large, active dogs. If you’re purchasing an outdoor kennel kit for your dog, you may be able to add panels to adjust its size. It’s best to avoid kennels smaller than five feet wide, even for small dogs.

How to Measure a Dog to Determine the Right Kennel Size

To measure your dog correctly, hold a flexible measuring tape at its feet and stretch it to the top of the head. Then add two to seven inches to this measurement to get the suggested standing height. This measurement will account for the dog’s height on its hind legs.

Next, measure the dog from its nose to the tip of its tail. If the dog’s tail is long, you don’t have to measure the entire thing. Again, add an extra two to seven inches to this measurement to get your dog’s required kennel length.

Additional Factors to Consider


Location is incredibly important when it comes to an outdoor dog kennel. It can make or break your experience. It’s important to ensure that the kennel is safe from harsher weather conditions, offers some shade for the warmer months, and can be easily cleaned. You’ll also want to play around with how close it is to your house. There’s likely a sweet spot where it’s close enough to make caring for the dog easier and not so close that you’re dealing with smells or insects near your home.

Strong waterproof can also be a great idea because they provide shade and keep falling debris or flying animals out. 

Cleaning & Flooring

Keeping your dog’s outdoor kennel clean is crucial for your pet’s health and happiness. When it comes to the floor or ground of your kennel, dirt and grass may not be a good option. Depending on where you live, it can become mud quickly, which makes cleaning especially difficult.

Concrete might be a suitable flooring, and it is easier to clean. Pea gravel or large flat stones could also be a good selection. You’ll need to replace the gravel yearly because you’ll lose some as you clean it. We recommend installing a 6-inch or deeper sand base underneath the gravel for drainage. 

Composite flooring specifically designed for outdoor kennel floors is also a good choice. These may cost a bit more. However, they’re effective, easy to install, clean nicely, and look great.
