Design a Sliding Door Wardrobe or Walk-in Closet Online, to Size

Flatma is a sliding wardrobe designer that works in your browser. Start from a ready sliding wardrobe or an open closet module, set the size of your wall, and plan the inside: hanging rails, shelves, drawers, shoe shelves and baskets. The 3D model gives you cutting maps and drawings with every hole, so the wardrobe is built as designed.

A Built-in Wardrobe Goes Wrong by Millimetres

A built-in wardrobe with sliding doors leaves little room for guesswork. The doors and their tracks take about 100 mm of the depth, so a carcass that looked deep enough on paper ends up too shallow for hangers. A partition where the doors overlap makes a section that never opens fully, with drawers that cannot be pulled out. Doors must be cut with the overlap counted in, and the back of a wide wardrobe will not fit on one board. When the sketch, the door sums and the cut list live apart, every change of width is carried through by hand, and mistakes surface at assembly.

Sliding Wardrobes from the Catalog, Sized to Your Wall

The Wardrobes section of the catalog holds ready models that land on the scene as ordinary parts you can change. For sliding doors, start from the Sliding wardrobe: give it your sizes, and its doors, tracks, rail and shelves follow.

The carcass is 16 mm chipboard, the doors 18 mm MDF, the back 3.2 mm hardboard. Change any of them in the material window, or give a door the Mirror, Gloss or glass surface to see the front.

Plan the Inside: Sections, Rails, Shelves and Drawers

Inside, a wardrobe is a row of sections, and in Flatma you can draw them: Draw, at the bottom of the scene, opens a front view where every line becomes a panel, and its Closets tab has ready sections.

  • Sections: rod and shelf, rod and drawers, two rods, shelves, rod and shoes, baskets and shelves, with doors, and a top box
  • The Inside tab fills an opening with a rod, pull-down rail, trouser rack, shoe shelf, one to three inner drawers or a wire basket
  • Rods sit on rail holders, drawers get their slides, and Create 3D model turns the drawing into parts with fasteners
  • Common practice: sections 400–1000 mm wide, shelves of 16 mm board no longer than 800–900 mm, or they sag
  • Leave 1500–1700 mm under a rail for coats and dresses, 900–1000 mm for shirts, so a tall section takes two rails
  • Shelves for folded clothes go 300–400 mm apart, for shoes 150–200 mm; a pull-down rail lowers clothes from the top

Doors in a drawing are hinged. For sliding doors, take the catalog Sliding wardrobe and change its inside on the model; drawn sections suit an open walk-in closet.

How to Design a Sliding Door Wardrobe Online

From measuring the opening to files for the workshop.

Step 01

Measure the Opening

Measure width, height and depth in several places: walls and ceilings are rarely straight. Take the smallest figures and leave a small fitting gap.

Step 02

Place the Wardrobe

In the Editor, click Catalog, open Wardrobes and click Sliding wardrobe. Set its width, height, depth, door overlap and shelf count in the Variables block, or describe the wardrobe to the AI designer.

Step 03

Plan the Inside

Add shelves, a second rail or drawers, then run Check intersections to see that doors, rails and drawers clear each other.

Step 04

Get the Documents

Documents shows the cutting maps and drawings; Download gives the PDF, the parts list in Excel or CSV and DXF files for CNC.

Walk-in Closet Planner: Modules along the Walls

A walk-in closet is open storage along one, two or three walls. Plan the room first, then line its walls with modules and see how much space is left to walk in.

  • Library, Scene, Room: a plan of any shape with its door, window and ceiling height
  • Open wardrobe has no doors: a rail under a shelf and a shoe shelf with a lip on one side, shelves on the other
  • Or draw a run of sections with rails, shelves, drawers and baskets in Draw and turn it into a model
  • Parts stick to the floor and walls, so modules stand against the wall and side by side
  • Common practice: 550–600 mm deep for hanging, 300–450 mm for folded clothes, an aisle of at least 600 mm, 800–1000 mm with storage on both sides
  • The room is only a backdrop and stays out of the cutting maps and files

To arrange the whole bedroom around the wardrobe, open the room planner. A walk-in closet gets the same cutting maps and drawings as a sliding wardrobe.

Cutting Maps and Drawings for the Workshop

When the wardrobe looks right, click Documents. Everything comes from the same model and updates after each change, so a wider wardrobe never leaves an old cut list behind.

Drawings are made from the model automatically: check the sizes against your measurements before ordering boards.

Sliding Wardrobe and Walk-in Closet FAQ

A common carcass depth is 600–650 mm. About 100 mm goes to the doors and tracks, leaving room for hangers across the rail; in a shallower wardrobe, shelves and drawers work better. The Sliding wardrobe in Flatma is 650 mm deep by default.
Yes. Add a room with its door and window, then line the walls with Open wardrobe modules or sections drawn in Draw. Leave an aisle of at least 600 mm, more with storage on both sides.
The Sliding wardrobe works out the door width from the wardrobe width and the overlap, and the door height from the space between the tracks. There is no calculator for a particular profile system: for framed doors, take the filling sizes from your system tables.
In the material window, a door can get the Mirror, Gloss, Clear glass or Frosted glass surface to show how the front looks. This is the look of the part; how a mirror door is built depends on your profile system.
