What size pet door do I need?

Pet door size should be based on the pet’s shoulder height, width, and comfortable step-over height. The opening should be large enough for safe use without oversized gaps that affect comfort, security, or energy performance.

For homeowners and residential property managers, the right answer usually depends on pet size, step-over height, glass panel size, and security/energy goals. A good FAQ post should make the decision feel clear without pretending every glass project is the same. In the Phoenix metro area, heat, sun exposure, dust, foot traffic, tenant needs, and security concerns can all change the best recommendation.

The safest next step is to have Arizona Glass & Door review photos, measurements, the property type, and any surrounding conditions before recommending a final scope. That keeps the visitor from guessing and helps route them to the right service: repair, replacement, resealing, window film, security film, custom glass fabrication, shower glass, mirror installation, board-up, or commercial door work.

Recommended next step: Request a specialty residential glass quote with photos, measurements, the room or opening location, and any leak, privacy, safety, or pet-access concerns.
