A wardrobe is a closet you can see, so the outside matters as much as the inside. That changes the design problem: the carcass depth is set by the hanger the same way a reach-in is, but the front now has to relate to the room, the ceiling and the baseboard.

These are the numbers the app's planner uses when it lays out a wardrobe.
| Measurement | Value | Why it matters |
|---|---|---|
| Depth, hanging | 24 in. | 22 in. is the absolute floor; 21 in. means side-hanging only |
| Depth, shelves only | 16 - 20 in. | A shallower unit reads lighter in a small bedroom |
| Standard height | 84 in. | Or full height to the ceiling with a filler panel above |
| Door width | 18 - 24 in. per leaf | Wider than 24 in. and the hinges start to sag |
| Swing clearance | Door width plus 6 in. | A 24 in. door needs 30 in. of clear floor |
| Sliding door overlap | 1 - 2 in. | Sliders cost you 4 in. of depth for the track |
| Toe kick | 3.5 in. high, 3 in. deep | Only if the unit is built in. Freestanding sits on a plinth |
Not every style fits every space. These three do, and each page has the material list and the cost per linear foot.
Photograph the space, choose Wardrobe as the closet type, and pick a style. To generate one from scratch instead, paste this into Dream Closet:
“Built-in wardrobe wall, full height to the ceiling, flat fronts, integrated handles, scribed to the walls with no gaps, interior with double hang and drawers, soft LED inside”
A closet is part of the building: a framed space with a door. A wardrobe is a piece of cabinetry, freestanding or built in, that sits in the room. Practically, the difference is that a wardrobe's exterior is a visible surface you have to design.
24 inches for front-facing hanging. If you only have 16 to 18 inches, use a side-facing pull-out rod, which hangs garments parallel to the wall. Capacity drops by about half but the clothes fit properly.
Hinged if the room allows the swing, because you get the full opening and 4 more inches of usable depth. Sliding when the wardrobe faces a bed or a walkway, accepting that you can only ever see half the interior.
