A three-part pony stable door has a top section and a bottom section divided into two panels. Open the top and middle panels to give a smaller pony a comfortable view outside while keeping the lowest panel securely closed.
You can also bolt the two lower panels together for a larger pony or horse, as long as the box is large enough.

At Chart Stables, we can include three-part pony doors when designing fixed stables, mobile stables and American barns.
Visit our stable doors and windows page to see the three-part pony door and compare it with our other door options.
Set the opening low enough for the pony to look outside comfortably, but high enough to contain it safely.
The British Horse Society recommends a minimum stable-door width of 1.25m (4ft), but it does not specify a standard bottom-door height for ponies.

Door dimensions are only one part of the design, so also check our horse stable size guide when planning the box.
A pony stable door needs strong materials, secure fastenings and no gaps where a hoof or leg could become trapped.
The door should open outwards or slide across rather than opening into the box. Secure top and bottom fastenings help prevent the pony from pushing it open or catching a leg between the door and frame.
Our stable door options use pressure-treated timber and galvanised fittings. We can also add anti-chew protection to vulnerable timber edges to reduce damage from chewing.
Check the door regularly for:
Repair any damage promptly and keep the fastenings working smoothly.

One customer asked us to fit three pony stables into a small, existing semicircular area. We created a bespoke layout to make use of the available space and fitted each box with a three-part pony door.
The lower openings suited the small ponies, while the adaptable doors meant that larger ponies or horses could use the boxes in the future. Each lower panel also had its own fittings and extended anti-chew protection.
This project shows how bespoke stables can accommodate both unusual spaces and different-sized animals.
Our guide to choosing your ideal stable block layout explores other ways to arrange stable boxes and facilities.
At Chart Stables, we design and build bespoke timber stables around your ponies, property and routine. Alongside three-part pony doors, you can choose the box sizes, layout, windows, partitions, roofing and storage areas that work best for your yard.
Our fixed and mobile stables use pressure-treated timber, strong framing and practical safety features. We can also help you plan for different-sized occupants or changes to your yard in the future.

Are three-part stable doors suitable for Shetland ponies?
They can work well for Shetlands because the additional lower panel can create a more comfortable viewing height. The correct arrangement will depend on the individual pony’s size and behaviour.
Does every pony need a lower stable door?
No. Some taller ponies can comfortably use a standard stable door.
Can you add a pony door to an existing stable?
It may be possible, depending on the existing opening, frame and condition of the building.
Should pony stable doors open inwards or outwards?
Stable doors should open outwards or slide across rather than opening into the box. This preserves the space inside and gives handlers a clearer exit route.
