The direct answer: the HOUT fence stands 30 inches (76 cm). If you came here hoping it was 40 inches or four feet, it is not, and no configuration changes that. Zipping sets together adds length, never height. The rest of this post is what 30 inches is good for, and how to tell whether that includes your dog.
What a 30-inch fence is doing
It marks a boundary. A dog inside a pitched fence can see out, and a dog outside can see in; what the panels do is make the edge of the space obvious and physical. That is the job on a campsite, on a deck, in a hotel room, at a friend's house with an open door. It is not the job of a barrier designed to stop a determined dog from leaving.
We say that plainly because two customers have now asked us for 40 inches, and one wrote that he wished it were four feet. They were not complaining about the build. They were describing a different product than the one we make.
Read the height against your dog, not the breed
Thirty inches is roughly waist height on an adult. Whether that is enough depends less on how tall your dog stands than on whether your dog is the kind that tries. A calm 70-pound retriever who has never left a marked space may settle inside it all weekend. A 25-pound terrier with a habit of climbing may be over it in a minute. Height charts by breed will not tell you which one you have; the last three years of living with your dog will.
If your honest answer is "she would try," then 30 inches is the wrong number for you and we would rather you know that before the box arrives than after.
HOUT Pet Fence Basic Ver 2
Height 30 in (76 cm). Poles are about 35 in (900 mm) before they go into the ground. Panels zip together, so sets add fence line, not height.
View productWhy the poles are longer than the fence
The poles measure about 35 inches, which is five inches more than the fence stands. That difference is buried. The stake and the lower section go into the ground, and the panel sits at 30 inches from the surface you pitched it on. On a hard deck where you clamp instead of stake, the same 30 inches applies. Nobody gets extra height by leaving the poles proud, and driving them shallower to gain an inch costs you the tension that keeps the line straight.
What we would suggest instead
If you need containment rather than a boundary, buy for containment: a tall exercise pen, a crate, or a leash line anchored to your vehicle. Those are different products with different trade-offs, and none of them fold into a 35-inch bag. We are not going to tell you our fence does a job it does not do, and we would rather lose the sale than read the review that follows.
If what you want is a defined space that goes up in a few minutes and packs down small, then 30 inches is the trade we made on purpose, and the fence line is where the real sizing question lives. That one we wrote about separately: how many feet of fence you actually need.
Questions we get
Can I stack two sets to double the height?
No. The panels zip side to side, not top to bottom. Two sets give you about 59 feet of fence line at the same 30 inches.
Does the All-in-One version stand taller?
No. It is the deck-and-ground version with clamps and stakes both; the height is the same trade.
My dog is a puppy now. Will 30 inches last?
For the space-marking job, usually yes, since that is about habit rather than reach. If you are counting on the panels to physically stop an adult dog later, plan for a different product now.
