Dog Crate Size Calculator
What Size Crate Does My Dog Need?
Enter two simple measurements and we will work out the minimum crate size for your dog, then match it to the crates and carriers we have in stock.
The right crate lets your dog stand, turn around and lie flat, without so much space that it stops feeling like a safe den. This free dog crate size calculator uses the measuring method most UK pet care guides recommend, then checks the result against the real sizes of the crates and carriers in our range.
How to Measure Your Dog for a Crate
Length: with your dog standing, measure from the tip of the nose to the base of the tail. Do not include the tail. Height: with your dog sitting up, measure from the floor to the top of the head, or the ear tips if they stand up. Then add a little room.
Width usually follows length, so most dogs do not need a separate width measurement. Crate sizes are listed as outside measurements, so the space inside is a few centimetres smaller.
Dog Crate Size Chart
| Crate length | Dog length up to | Rough weight guide | Often fits |
|---|---|---|---|
| 60cm (24in) | about 45cm | up to 11kg | Chihuahua, Yorkie, Pug, Shih Tzu |
| 76cm (30in) | about 60cm | 11 to 18kg | Cavapoo, French Bulldog, Beagle |
| 92cm (36in) | about 75cm | 18 to 30kg | Cocker Spaniel, Staffie, Border Collie |
| 107cm (42in) | about 90cm | 30 to 40kg | Labrador, Golden Retriever |
| 121cm (48in) | about 105cm | 40kg and over | German Shepherd, large Retrievers |
Weight is only a rough guide. A long, low Dachshund and a tall, short backed dog of the same weight need very different crates, so measure if you can.

Wire, Soft or Hard Crate?
Folding wire crate
Strong, airy and easy to clean, with a removable tray. Best for home, puppy training and dogs that chew. Folds flat for the car.
Soft folding crate
Light, quick to pop up and good for trips and holidays. Best for calm, crate trained dogs, as a determined chewer can damage fabric.
Hard or soft carrier
For small dogs and cats on short trips, such as vet visits. Check the weight limit as well as the size.
See every option in our dog crates range, and add a washable crate mat for comfort.
Using a Crate in the Car
Highway Code Rule 57 lists a dog cage as one way to keep your dog suitably restrained while you drive. Measure your boot as well as your dog, and make sure the crate fits with the parcel shelf removed and the boot closed. Secure the crate so it cannot slide, and read our guide on putting a dog in the boot. If your dog rides on the back seat instead, try our car seat size calculator or harness size calculator.
Too Big or Too Small? Check the Signs
Too small
- Head touches the roof when sitting
- Cannot turn around without bumping the sides
- Lies curled up even when hot
Too big
- Puppy toilets at one end and sleeps at the other
- Dog slides about when the car moves
- Does not settle and treat it as a den
Choosing a Crate for a Puppy
Buy for the adult size, so you only buy once, then block off the extra space with a divider panel or a firm box while your puppy is small. This stops a puppy toileting at one end. Move the divider back as your puppy grows. The code of practice for the welfare of dogs covers your dog's need for a comfortable, safe place to rest.
Comfort first. A crate should be a calm resting place, never a punishment, and dogs should not be shut in for long periods. Our crates and carriers are for comfort and containment and are not crash tested.
Crate Sizing Questions
What size crate does a Labrador need?
Most adult Labradors need a 107cm (42in) crate. Large or tall males may be more comfortable in a 121cm (48in) crate.
Should a dog be able to stand up in a crate?
Yes. Your dog should be able to stand, sit up without the head touching the roof, turn around and lie flat.
Is it better to buy a crate too big or too small?
Slightly big is better than too small. For a puppy, use a divider so the space feels snug.
Can I use the same crate at home and in the car?
Often yes, if it fits your boot and can be secured. A folding wire or soft crate is the easiest to move between the two.
