How to choose crates

How to measure

  • Measure from nose to base of tail for crate length.
  • Measure from floor to top of head or ears while standing.
  • For puppies, consider a divider crate when safe and appropriate.

Common mistakes

  • Buying only by weight.
  • Choosing a crate so large that puppies can soil one end.
  • Forgetting door height for tall breeds.

Helpful features

  • Adjustable divider
  • Rounded corners
  • Easy-clean tray
  • Secure latch

Use the brand chart

What to bring to a crate size chart

Start with these details

Bring your measurements and these checks to the product page before you buy. This is the fastest way to avoid guessing from breed, size labels, or weight alone.

Interior crate length based on your dog's body length, not just the brand label.

Standing height to the top of the head or ears, especially for upright breeds.

Divider availability if you are sizing for a puppy that will grow.

Door opening, latch style, and tray depth if the crate will be used every day.

Planning guide

How to narrow down crates faster

Long-bodied dogs

Prioritize interior length first.

Weight-based shopping often runs short for dogs like dachshunds and corgis.

Tall or upright dogs

Compare standing height and door clearance.

Top-of-head and ear room matter more than the listed weight range.

Puppies

Buy for adult size and use a divider when appropriate.

Too much open space can make crate training harder.

Furniture or travel crates

Recheck usable interior dimensions.

Styled crates can offer less interior room than the outside size suggests.

Between sizes

When to size up, size down, or keep comparing crates

Scenario

Your adult dog cannot stretch or turn comfortably in the smaller crate.

Size up and confirm the larger model's interior length and height.

Scenario

A puppy lands between two crate sizes.

Choose the adult-size crate and use a divider instead of buying a crate they will outgrow quickly.

Scenario

You only know your dog's weight.

Pause and measure length and standing height before ordering because crate sizing is easy to miss by weight alone.

Scenario

A soft-sided or travel crate runs smaller than a wire crate.

Compare the actual interior dimensions rather than assuming the same nominal size will fit.

FAQ

Crate sizing questions

Can I choose a crate by breed alone?

Breed estimates are helpful, but every dog is different. Use your dog's actual measurements whenever possible.

What should I do when my dog is between sizes?

Check the brand's chart and fit notes before ordering. Adjustable products can help, but safety and comfort come first.

Do puppies need different sizing advice?

Puppies grow quickly, so adjustable gear can be useful when safe and appropriate. Recheck fit often.

How much room should a dog have in a crate?

A dog should be able to stand naturally, turn around, and lie down comfortably. Too much extra space can be a problem for puppies during house training.
