Dog Door Sizes by Breed

Use breed ranges as a starting point, then confirm the individual pet’s measurements before ordering.

premium SIZING GUIDE Dog Breed Sizing Guide

Search more than 2,200 dog breeds to find the right premium pet door size. Each recommendation includes the most common door sizes for that breed, along with typical height and weight ranges.

If your dog falls between sizes, size up. A slightly larger opening is almost always better than forcing your pet through a door that is too tight.

Breed recommendations are a strong starting point, but your pet’s actual shoulder height and width should always be the final decision-maker.

Planning and installation

Use the breed table as a shortlist, not the final order

Breed ranges describe typical populations, not a guarantee for an individual dog. Mixed heritage, sex, age, body condition and natural variation can place a pet outside the expected height or weight. Use the table to identify two or three likely flap openings, then measure body width and shoulder height directly. If the dog’s measurements conflict with the breed recommendation, follow the measured animal and verify the complete frame at the installation surface.

Large and giant breeds often need height without the full width of the broadest opening. Tall Large, Tall Large Plus and Extra Tall Large choices exist for that reason. Conversely, a broad, shorter dog may need more width without a very tall flap. Compare dimensions rather than moving automatically from Medium to Large to Giant as though every body shape scales in the same proportions.

Planning and installation

How to use this guide with a made-to-order product

Use the guide as one part of an order record, not as a substitute for the exact product page and model instructions. Keep the pet measurements, selected flap size, rough opening, exterior frame dimensions, installation surface, finish, flap package and final SKU together. When a contractor or glass professional is involved, add that person’s verified construction dimensions without replacing the measurements that established pet fit. This creates a traceable path from animal to opening to ordered configuration.

Review the information again immediately before submitting an order. Similar terms can describe different dimensions: flap opening is the clear passage, rough opening is the prepared hole, and tip-to-tip is the outside frame. A wall depth, screen-panel width or glass cutout is another construction measurement entirely. Label every number and attach the exact manual to the location. If a fact is uncertain, pause and verify it instead of turning an assumption into a made-to-order selection.

Planning and installation

Keep the guide useful after installation

Save the guide, order confirmation, photographs and installation notes after the pet door is in service. Record the model, named size, flap count, frame finish and any wall tunnel, cover orientation or screen stabilizer. That information makes replacement flaps, magnets, weather strip, covers and locks easier to identify later. It also helps separate normal component wear from an opening that was installed out of square or a building seal that needs repair.

Inspect the completed opening as part of normal home or facility maintenance. Keep flap edges and magnets clean, watch for curled vinyl or damaged weather strip, confirm covers move freely and review exterior perimeter seals. The rigid frame and the flexible service parts do different jobs and may have different service lives. Replacing a verified wear component early is usually simpler than waiting until repeated contact or a persistent gap affects the rest of the system.

Planning and installation

Turn the guide into a clean project handoff

A useful handoff lets the installer, customer and future service person understand the same configuration without translating shorthand. Name the location, identify the surface, list the pet-door model and SKU, and separate clear flap, rough-opening and outer-frame dimensions. Add wall or door thickness, screen support, glass-fabrication information and cover orientation when they apply. Put approvals next to the fact being approved rather than collecting an unlabeled yes in a message thread. This structure reduces the chance that a correct measurement is attached to the wrong opening or product family.

After installation, add the completed mounting height, photographs from both sides and any approved field adjustment. Keep policy, shipping or warranty communications with the order instead of rewriting their terms in the measurement sheet. The guide can then remain focused on product selection and care while current written policies control eligibility. When ownership or maintenance responsibility changes, pass the record forward with the physical cover, spare parts and manuals. A well-documented pet door is easier to operate, inspect and repair than an opening identified only by its visible color and approximate size.

Finish by choosing the next practical action. If fit is still uncertain, return to the exact flap and frame dimensions. If the product is selected, move to the installation guidance for the actual surface. If the opening is already in service, identify the model and size before choosing replacement parts. Custom work deserves an extra measurement review because one unlabeled number can undo otherwise careful planning. Save the final configuration with the measurements, photographs and installation notes so the next decision starts from verified information.

Frequently asked questions

Is every dog in one breed the same pet-door size?+

No. Breed data is a starting range. Measure the individual dog before selecting a flap opening.

What if my dog falls between two listed sizes?+

Compare actual openings, step-over and the available frame area. Size up only when the larger option improves comfortable passage and still fits the building.

Can I use the adult breed size for a puppy?+

Expected adult size can guide planning, but growth is uncertain. Confirm likely adult measurements and make sure the present mounting height remains manageable during training.
