Hale Pet Door
Sizing Tips and Information

But I Can Fit...
We've all seen the funny internet videos and photos of animals squeezing through pet doors that are obviously too small for them.  But while we may laugh at their antics choosing the correct size pet door is actually a matter which can affect your pet's long-term health and well-being.

Matching the Door to Your Pet is Important
If a door is too short it can injure your pet's hips and back over time.  If it is too narrow it can damage their fur or skin when squeezing through. If it is too tall (off the ground) it can hurt their underneath sides as they scrape over it.  Pick the door that is comfortable for your pet.

Hale Offers Lots of Choices

One of the things that sets Hale Pet Door apart from its competitors is the wide variety of standard sizes we offer to fit almost any animal and almost any application.  Many pet door companies only offer small, medium and large sizes but we have 12 standard sizes that are designed to work with not only the size of your pet but the size of the installation location.

We also offer custom-made doors of almost any size if your dog is larger, your space is constrained, or your installation location is unique. For more information on custom sizing, pricing, and ordering, please click here

We are pleased to be able to provide you with the following information to make choosing the correct pet door easy.

Measure Your Pet for the Correct Size
There are three measurements to take into consideration when choosing the correct size door: 1) the width of the passage opening, 2) the height of the opening, and finally, 3) the “rise” or the lip at the bottom of the door that the pet must step over to use the door. Use the following guidelines to ensure a proper fit for your pet.

Other Things to consider

Older pets don’t like to use pet doors that are uncomfortable. Make sure you get a door that your pet will always be able to use. If you currently have a kitten or puppy, remember that they will grow.

Mount the pet door so that it is low enough for your pet to comfortably step over. Young pets can raise their legs up to their chest but older pets may have trouble with this.

Make sure the pet door is tall enough for your pet. Hunching over can be hard on your pet’s hips, especially as they age. And the flaps on your door will last longer if your pet isn’t rubbing against the top of the door as he passes through.

If you have more than one pet, make sure you get a door that will work for all of them: low enough for the shortest one to step over but tall enough for the tallest one to fit through comfortably.

Don’t forget that your pet needs access from both sides of your pet door. If you are installing the door in an area that has steps outside, please take into consideration how your pet will have to get through the door. This is especially true of our panel models. They have a standard rise of 5” but can be ordered with no rise (actually about 1” of frame to step over) instead to make it easier for your pet.
