Short Answer
Measure your pet's width and height, then add 50 mm (2") to both measurements to ensure they can comfortably use the pet door.
If you're choosing a Patio Pet Door, remember that your pet will need to step over the bottom frame to enter the pet door. The height of this frame varies between products and sizes, so it's worth considering - especially for shorter, older or less mobile pets.
Why Measuring Matters
Measuring your pet before purchasing helps you choose a pet door they can use comfortably every day.
For all Hakuna Pets pet doors, you'll need to measure:
- Width
- Height
If you're choosing a Patio Pet Door, you'll also need to consider the height of the bottom frame, particularly for smaller, older or less mobile pets.
Step 1: Measure Your Pet's Width
Measure the widest part of your pet, usually across the chest.
Add 50 mm (2") to allow comfortable clearance.
Step 2: Measure Your Pet's Height
Measure from the bottom of your pet's chest or belly to the top of their shoulders.
Add 50 mm (2") to allow comfortable clearance.

Measuring for a Patio Pet Door
Unlike standard pet doors installed into timber doors or walls, Patio Pet Doors have a frame at the bottom that your pet steps over to enter and exit.
This is an important consideration for:
- Short-legged breeds
- Puppies
- Senior pets
- Pets with mobility concerns
Some Patio Pet Door accessories can also raise the flap position to provide additional clearance for taller pets.
If you're purchasing a Patio Pet Door, see the product-specific guides below for information about flap clearance and bottom frame heights:

Important Considerations
- Always add 50 mm (2") to your width and height measurements.
- Measure your largest pet if multiple pets will use the door.
- If your pet is still growing, allow additional room for future growth.
- If you're purchasing a Patio Pet Door, remember to consider both the flap clearance and the bottom frame height to ensure your pet can use the door comfortably.
Because every pet is different, customers should always measure their own pet before selecting a pet door.
