Cat Door & Dog Door Sizes

If you have chosen to install a pet door for you cat or dog, you have made a decision that will make your pet more comfortable and give it more control over it’s own domain.  Dog door sizes will determine the right dog door for your dog.

In order to install the right size door and ensure that is positioned correctly for your particular pet, you will need to take some measurements beforehand.  Measuring up your pet for a pet door is not difficult.

Factors that influence size and position of pet doors

The following information will be useful when ordering a pet door.

  • Pets overall height
  • Width of pet body
  • Depth of the pets chest
  • Distance from ground to pets body
  • The height and width of your glass panel
  • Distance from the ground to the bottom of the glass

Tips for measuring your dog

Many dogs don’t like measuring tapes, therefore the following tips may help you get these measurements.

Measuring up your dog for a dog door does not necessarily mean wrestling him down so you can measure him.

For height, have your dog stand next to a wall, and mark the wall at his tallest point with some chalk.  This is usually at the shoulders, but for some breeds, it may be elsewhere.  Disregard the head height for the moment.

This measurement will help you make sure he is not scraping his back when he uses his door.  If he is standing still well for you, mark the wall just below the lowest point on his belly, which will tell you about how high off the ground the door should be installed.

In order to measure the width of your dog, hold any door partially open and invite it to walk through slowly.  This way you’ll know what the dog can fit through.

Measure this opening and add a few centimeters on either side.  Now you have the information you need to order the correct door for your dog to use comfortably. Read on to find information about dog door sizes.

Tips for measuring your cat

Measuring up a cat for a cat door is even easier than measuring a dog.  The most important measurement is the distance from the floor to your cat’s belly; this will usually be four to six inches. 

Unless you have a particularly large or small cat, a standard cat door will be sufficient for your precious feline.

Other factors that influence pet door size

Keep in mind for either pet that there are a few other factors to consider other than measurements. 

  • Is you dog a puppy?
  • How tall are the parents?
  • Is your pet older?
  • Does your pet have arthritis?
  • Is your pet overweight?
  • Is your pet agile?

If your pet is very young, you will need to account for expected growth so that you do not have to build a new door in a few months; however, you must be sure that the door is not too big or too heavy for your pet to use right now. 

If there is a vast difference between his size now and his expected size in a few months, it might be wise to wait until he is a bit bigger.
