When it comes time to choose a new crate for your pup, more than just convenience should be at the top of your mind. The crate you choose directly impacts your pup’s comfort, safety, and overall well-being. When the crate is too small, it becomes too restrictive, and when it’s too big, it really just defeats the purpose of crate training altogether.
So, if you’re wondering how to measure your dog for a crate, you’re not alone. Many dog owners like yourself have guessed on sizes based on the breed of dog and their weight. But it’s important to know that accurate measurements for a crate make all the difference.
Why You Need the Right-Sized Crate
Before you bust out your tape measure, you want a good understanding of why the size actually matters so much. Dogs are naturally den animals and look for a space for rest and security. The right-sized crate:
-
Helps with house training
-
Prevents anxiety during travel or downtime
-
Protects your dog from household hazards
-
Encourages restful sleep
-
Creates a consistent, safe space for them to escape to
If the crate’s too big, your pup might decide to take advantage of all that space and use half of it for sleeping and the other half as a bathroom. When it’s too small, your dog won’t be able to stand up, turn around, or stretch out comfortably.
When you choose the right size, you can strike the balance your pup needs with coziness and freedom of movement.

What You Need to Measure Your Dog
Measuring your dog is simple and only requires a few things.
-
Find a flexible tape measure (a fabric measuring tape works best)
-
Grab some treats or a helper to keep your pup still
-
Some paper or your phone to record the numbers as you go
The best time to measure your pup is when they’re calm. Try after a long walk or a meal. Now, here are the steps to follow:
Step One: Measure Length
Consider this the most important measurement. To measure the length, have your pup stand naturally on all fours. You then measure from the tip of their nose to the base of their tail (not the tip of the tail). You should then add approximately two to four inches to that number for comfort. This added space lets your pup stretch and shift positions.
Step Two: Measure Shoulder Height
Next, you need to measure the vertical space your pup will need in their new crate. To do this, keep them standing upright, and then measure from the floor to the highest point of their shoulders (or ears if they stand erect). Add two to three inches here so you can ensure your pup can stand comfortably without having to crouch.
Step Three: Measure Width
This step is optional, but can be helpful. We recommend measuring the width if your pup tends to sleep sprawled out, has a broad chest, or is just a stocky breed. Measure the widest part of their chest while they’re standing and then add a few inches to prevent crowding.
Step Four: Sleeping Style
We’ve shown you how these measurements provide you with the numbers you need to size a new crate, but you also have to consider your dog’s sleeping style. Does your pup curl up tightly when sleeping, or do they like to stretch out all the way? Do they move around and shift positions a lot? Are they still growing? More crate length can be beneficial if your pup loves to stretch.
Step Five: Match the Measurements to Crate Sizes
You will find that many crates come in general size ranges. Keep in mind that these are just approximate estimates and can vary.
-
Toy Breeds: 18-22”
-
Small Dogs: 24-30”
-
Medium Dogs: 30-36”
-
Large Dogs: 36-42”
-
Extra Large Breeds: 42-48”
Never just go by breed assumptions alone. You should always compare your dog’s measurements before you actually purchase their new crate.
Also, if you’re measuring a puppy, consider what their expected adult size is, and you can use a crate divider so they can grow into the space safely.
Choosing a Quality Crate Also Matters
Size is only a part of the bigger picture when looking for a new crate for your furry friend. You also want to take a long, hard look at its durability, safety, and design. This is especially true if your dog is active, loves to travel, or is a long-term crate user.
Many dog owners find themselves gravitating toward Rock Creek Crates. These crates are known for their ruggedness, durable construction, and thoughtful design. So, if you’re looking for heavy-duty durability, ventilation, visibility, travel-ready strength, and long-term reliability, look no further.

Different Crate Types
The next thing you should keep in mind is that not all crates are made to serve the same purpose. Let’s take a look at some of the different types, so you have a good idea of what you should lean toward and what should be avoided.
-
Wire Crates: These are best for home use and ventilation. They tend to be lightweight, affordable, and have good airflow, but are less durable for stronger dogs.
-
Plastic Crates: Plastic kennel crates are sometimes used for travel because they are airline-friendly and give your pup that cozy, den-like feel they want, but they don’t hold a candle to other crate types that are safety-rated and much more durable.
-
Heavy-Duty Crates: These crates are designed with strength and security in mind. They are extremely durable, escape-resistant, and can be considered a long-lasting investment and one worth making. Again, this is where Rock Creek Crates stands out.
What to Avoid When Measuring Your Pup
Even if you think you’re being careful, mistakes can still be made. Here are a few of our tips on what you should avoid when measuring your dog:
-
Guessing measurements based on breed type
-
Forgetting that your pup will grow
-
Measuring your pup while they’re sitting or lying down
-
Choosing a crate with the exact matching measurements instead of adding in those few inches of comfort space
What If Your Pup Is Between Sizes?
This can definitely happen, too! So, if you find this happens, choose a larger crate if you’re unsure. Again, you can also use a crate divider when you have puppies, and prioritize standing and turning space in the crate. Going with a crate that is just slightly larger is better than going with one that’s just too small.
Crate Training Tips
Once you’ve found the right crate, you want to use treats, toys, and calm praise to introduce it to your pup. Do this slowly and avoid rushing them to like it. You want your pup’s curiosity to build, so don’t force them into it if they’re not ready. You want them to see their crate as a safe space and not a punishment.
You should always make sure the crate is as comfy as possible for your pup as well. You can do this by adding some bedding and familiar scents. Finally, consistency when crate training helps reduce anxiety, so maintain a routine.

Are There Special Considerations for Travel Crates?
Yes! If you plan on traveling with the new crate, you definitely want to check airline requirements. You also want to ensure the crate has proper ventilation, secure latches, and is as durable as can be. You want a travel crate that combines safety with comfort.
Are There Signs to Let You Know You Made the Right Choice?
Well, if you’re looking for validation that you measured correctly and found the right size crate, here are a few things to look out for:
-
Your pup walks in willingly
-
They turn around easily
-
They can lie down comfortably
-
They can stand without having to duck down
-
Their body language is relaxed and calm
If your pup does everything they can to avoid the crate, then sizing might be a big issue.
How Do You Know if It's Time for an Upgrade?
You might find your pup needs a new crate if they start outgrowing it or it’s damaged in any way that could compromise their safety. You might also find that your travel needs have changed or your pup’s anxiety and escape attempts increase. Upgrading to a sturdier crate usually resolves these issues.
Our Final Thoughts on Measuring Your Dog for a Crate
Learning how to measure your dog for a crate doesn’t have to be complicated or take long to do. It’s relatively easy, takes little time and can make a big difference in your pup’s comfort and security. A properly sized crate supports better sleep, easier training, safer travel, and less stress overall.
So, take your time with the measurements, consider your pup’s behavior, and choose a crate that strikes the balance you both need between comfort and durability. Many dog owners recommend investing in a strong, well-designed option like Rock Creek Crates when long-term reliability is at the top of the list.
Make sure your dog’s crate feels like a safe retreat and not a tight squeeze or oversized empty box where they are doomed to live out their days. Accurate measurements are a good first step toward creating (and giving) them the space they deserve.
