An indoor rabbit pen should create a useful piece of floor, not a tiny cage with taller walls. The floor plan comes first. After that, choose the panel height and human access that fit the rabbit, the room, and the person who will enter it every day.
Rabbit.org's housing guidance describes a four-by-four-foot puppy pen with daily time outside it as an ideal starting point for many indoor rabbits. The San Diego House Rabbit Society adoption guidelines use a four-by-four-foot exercise pen with a thirty-inch minimum height for one rabbit. The RSPCA indoor-rabbit guide calls for a large secure exercise area, a solid non-slip floor, and enough room for normal behavior.
Each pen here uses eight panels that are twenty-four inches wide. Closed as a square, each one makes the same four-by-four-foot, sixteen-square-foot floor. They are alternatives, not a bundle. What changes is the height and whether a person can step through a door.

| Pen | Floor | Height | Access |
|---|---|---|---|
| MidWest 30 inch with door | 4 by 4 feet; 16 square feet | 30.08 inches | Step-through door |
| MidWest 36 inch without door | 4 by 4 feet; 16 square feet | 36.07 inches | No door |
| MidWest 48 inch with door | 4 by 4 feet; 16 square feet | 48.04 inches | Step-through door |
The picks
The thirty-inch MidWest is the easiest of these three for a person to enter because it has a step-through door. It makes the same sixteen-square-foot square as the taller versions, so choosing it does not mean giving up floor space.
The tradeoff is the lower boundary. Thirty inches is the starting point used by the San Diego House Rabbit Society for one rabbit, not a promise that every rabbit will remain inside. Keep sofas, storage cubes, hides, and other launch points away from the outside panels. If the rabbit is already a confident jumper, start with the taller options.
The thirty-six-inch version adds six inches of height and removes the door. That creates an uninterrupted boundary, but it also changes the owner routine. A person has to step over the panel or open the connection whenever the pen needs to be entered.
Test that movement before buying. Tape a thirty-six-inch line on a wall and picture carrying hay, a litter tray, or a rabbit across it. If that daily step feels awkward, the extra height is not worth losing a safe entrance.
The forty-eight-inch version combines the tallest boundary here with a step-through door. It is the clearest starting point for a known jumper or a room where the pen sits near furniture that cannot be moved far away.
It is also the largest physical object to handle. The taller panels are heavier, need more vertical storage room, and can make the pen feel more enclosed from a seated position. Map the folded storage spot and the open door route before checkout.
Build the room in this order
- Tape the floor. Mark a four-by-four-foot square and walk around it from every side.
- Choose a solid surface. Use a non-slip floor or a flat washable rug that cannot bunch under the panels.
- Plan the human entrance. Open the door or panel where hay, water, litter, and cleaning supplies can move through without twisting.
- Move launch points. Keep sofas, shelves, hides, and platforms away from the outside edge.
- Add the toilet and hay end. Leave open floor after the tray, hay, water, and hideouts are in place.
- Watch the rabbit. Check reaching, jumping, chewing, and panel movement during ordinary activity.
What the height changes
All three pens use the same amount of floor when arranged as a square. The higher versions do not create more room to run, stretch, or share. They only change the vertical boundary.
The door changes the owner's route. A step-through opening can make feeding and cleanup easier, especially when the person is carrying a loaded tray. A doorless pen keeps the boundary continuous, but only works when the owner can comfortably cross or open it every day.
The RSPCA enrichment guide warns against filling the living space with so many objects that the rabbit loses room to move. Give every hideout and tunnel a job, then protect the open route between them.
The room-fit check
- The finished pen still gives the rabbit room to hop, stretch, stand, and turn.
- A compatible pair can pass each other without one blocking the only route.
- The floor is solid, level, and non-slip.
- The litter tray, hay, water, and hideouts leave open movement space.
- The owner can enter with both hands occupied.
- The door or panel connection is fully secure.
- Furniture and platforms do not create a launch point beside the boundary.
- The panel height matches the rabbit's observed jumping, not only the product label.
Use the rabbit housing guide to plan the whole room, then compare the three pen roles or open the side-by-side decision desk. The rabbit supply map connects the boundary with litter, hay, hideouts, and daily care.
