A puppy crate must be just large enough to stand, turn, and lie down. Too large and puppies use a corner as a bathroom. Enter current weight to find the right size.
Find the ideal crate size for your puppy — sized for comfort and potty training success.

Crate size directly determines whether crate training works. A correctly sized crate triggers the natural instinct to keep the sleeping space clean. A crate that is too large allows your puppy to sleep at one end and use the other as a bathroom — defeating the purpose entirely.
The most common crate training mistake is buying a crate that looks comfortable and roomy for the puppy's current size, not accounting for the fact that excess space undermines the potty training mechanism. If your puppy has accidents in their crate consistently, crate size is almost always the first thing to check — either the crate is too large, or the puppy is being left in it longer than their age-appropriate bladder capacity allows.
The divider panel solution: Purchase the adult-sized crate with a divider panel and use it to create the appropriately sized puppy space now. Use our Adult Weight Calculator to estimate adult weight, find the adult crate dimensions, then buy that size with a divider. This is what most professional trainers recommend — one crate purchase that grows with your dog.
Wire crates are generally the best choice for puppies: good ventilation, easy to clean, include dividers, and fold flat. The open visibility helps puppies feel less isolated. Place the crate in a social area — bedroom or living room — rather than isolated rooms. Puppies who can hear and smell their family settle into crates much faster than those who feel exiled.
Add 3-4 inches to your puppy's standing height for the minimum crate height. A puppy that cannot stand comfortably will be stressed and unhappy. If your crate is slightly too short, a taller model is worth the investment — a comfortable puppy accepts the crate as a rest space far more readily than an uncomfortable one.
Crying in a correctly sized crate usually means the introduction was too fast. Return to basics: feed all meals in the open crate, scatter treats inside throughout the day, let entry be completely voluntary for several days before closing the door. Build duration in 2-minute increments only after the puppy enters and rests willingly.
Playpens can supplement crate training but typically do not replace it for potty training because they are too large to trigger the den instinct. Playpens are excellent for supervised free time when you need your puppy contained. For overnight and potty training, the correctly sized crate remains the most effective tool.
Maximum daytime crate time: 8-10 weeks = 1-2 hours, 12 weeks = 2 hours, 16 weeks = 3 hours, 20 weeks = 4 hours. Overnight puppies can often hold longer because activity levels are lower. Never leave a young puppy crated for a full 8-hour workday without a midday break from a pet sitter or dog walker.
