11 Standard Sizes and Custom Pet Door Options

These options are designed to work with not only the size of your pet but the size of the installation location.


How Do I Find the Right Size?

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 11 standard sizes that are designed to work with not only the size of your pet but the size of the installation location.

shoulder measurement for dog

Measure from ground to top of your pet’s shoulder

The pet door flaps should be at least an inch or two above the top of your pet’s back not the head. To get this height, measure your pet from the withers (top of the shoulders) to the floor. Remember that your door won’t be placed completely at floor level. If you have more than one animal, measure the tallest one.
If you have trouble getting your dog to stand still to be measured, you can try standing next to your dog, putting your fingers level with his shoulders on your leg and then measure from the floor to that spot on your leg.

chest measurement for dog

Facing your pet, measure across their chest

This is the easy one. Simply measure your pet at the widest point and add an inch or two for safety. If your pet is long-haired, don’t forget that this may make them appear wider than they really are.
Alternately, you can open a door just wide enough for your pet to pass through and measure the width of the opening, again adding an inch or two for safety.

Don’t forget to measure the step-over or ‘rise’ (for panel models)

The rise is the lip at the bottom of the door that the pet must step over to use the door. This measurement is generally only applicable for panel models which come with the rise built in. If you have a short-legged dog or an older dog that can’t lift his feet very high, or if the door is installed with a step on either side, consider ordering a “no rise” door. Our standard rise on panel models is 5” or 10”.

When Measuring Your Dog, Don’t Forget…

Dogs together

A puppy will grow!

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 door a comfortable height

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

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.

Need a door for multiple pets?

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.

OutDoor Setup with dog door

Access from both sides of your pet door

Please take into consideration how your pet will have to get through the door, especially if there are steps or if you have baseboards 3” or 6”. Panel Models have a standard rise of 5” but can be ordered with no rise.

Standard size pet doors are taller than they are wide

Some dogs (i.e. Bulldogs) may need more width but not as much height. In those instances, you can order a custom size so you aren’t getting a taller pet door than needed.

How to measure your door for replacement flaps

In some situations, the standard size door that will fit into the desired spot is too small for the pet, but the next largest standard size is too big for the location. In that instance, a custom size door will be the best solution to maximize the usable space.

Perhaps you previously had a different brand pet door installed and would like to replace it with a Hale Pet Door™ to fit the same rough opening. Or maybe you want a French door install that fits exactly into the opening left by removing one of the panes of glass.
