What Size Dog Fits in a Medium Crate? Guide + Chart

What size dog fits in a medium crate?

A “medium” dog crate typically fits dogs in the 25–50 lb range, depending on the brand’s exact dimensions. Most medium crates are around 30–36 inches long. The right fit lets your dog stand up without crouching, turn around easily, and lie down fully stretched without being cramped. Common medium-size breeds that often suit a medium crate include Beagles, Cocker Spaniels, French Bulldogs, Border Collies, and small Bulldogs—but always measure your dog to be sure.

Typical medium crate dimensions

• Medium (approx. 30″ L x 19″ W x 21″ H): Often suits dogs about 26–40 lb.
• Large-medium (approx. 36″ L x 23″ W x 25″ H): Often suits dogs about 41–60/70 lb.

Because “medium” isn’t standardized across brands, check the actual measurements before buying.

How to measure your dog for a medium crate

1. Length: Measure from nose to base of tail. Add 2–4 inches.
2. Height: Measure from floor to top of head or ears (whichever is taller). Add 2–4 inches.
3. Width: Ensure enough room for your dog to lie on their side comfortably.

If your measurements land between a 30″ and 36″ crate, choose the larger size so your dog has a cozy, comfortable lounge space that still feels secure.

Comfort and safety tips

• Use a supportive crate pad or bed to protect joints and add warmth.
• For puppies: use a divider panel so the crate grows with them while staying cozy.
• For travel: pair the crate with organized pet travel essentials and a sturdy carrier or tote for walks and quick outings.

FAQ

Generally, dogs around 25–50 lb fit a medium crate, but always use your dog’s measurements. Aim for 2–4 inches of extra space beyond your dog’s nose-to-tail-base length and standing height.

What size crate for a 70 lb dog?

Many 70 lb dogs do best in a 42″ crate, though some compact builds fit a 36″. Measure your dog and size up if they’re lanky, tall, or need extra stretch room.

How to tell if a dog is too big for a crate?

If your dog can’t stand without ducking, struggles to turn around, or can’t fully stretch out, the crate is too small. Look for relaxed posture, easy movement, and comfortable rest.
