What size PlexiDor should I get?

I post about pet door sizes from time to time, because this is one of the most common questions that come my way. People will look at the pet door and say, "That's so small. No way my dog/cat can get through."

The PlexiDor shouldn't be mounted
flush with the floor.
The door does not need to be as tall as the pet. It has to be wide enough to let the pet through, of course, but it doesn't have to be as tall as the pet. 

Check out the image to the right of a Collie standing in a door. The door isn't flush with the floor. It could be, but you want a small hole to help keep weather outside.

Theoretically, a dog door could be as tall as the dog. Imagine a Great Dane. That would be a large hole in the door or wall! A door that size would also become heavy for the pet to open.

Generally, the pets duck their heads a little while going through the door, and they lift their feet to step over the threshold. Thus, if you measure your pet and think, "Oh no, there's no door tall enough for my dog" it will probably still work.

If you have larger and smaller pets together, the panels on the PlexiDor swing so easily smaller dogs and cats can usually open even large doors without problems.

To make sizing easier, we have put together a convenient sizing chart, see below. Some breeds have great variations in size, of course, so see the breed examples as general guidelines.

Visit the Plexidor website for more information on the different doors and sizes. The website also holds a convenient dealer locator


  1. Good point! You automatically think it needs to be as tall as the dog, but that is not the case.

    1. It seems a reasonable assumption since our doors are as tall as we are, but it can be an expensive mistake. Thank you for coming over! =)

  2. I'm so excited that I chose the right size pet door for our dogs. It's perfect!

    1. Awesome! I'm happy it works well for you! =D Thank you for coming over! =)
