How the Pax System Actually Works When You Stop Reading the Manual
The Ikea Pax wardrobe planner is a free web tool, but it is not particularly useful unless you already know how to use it correctly. Most people open it, drag some boxes around, and assume the output will magically fit their space. It will not. The planner works in increments and assumes walls are flat, floors are level, and that you actually want factory-standard interior layouts. None of those assumptions hold up in a real apartment or house built before 2020. I started working with Pax systems in 2017, before the planner tool was really polished. I assembled probably forty units across that timeframe, and I learned quickly that the software and the physical product exist in two different universes. The planner will give you a configuration. The hardware will sometimes refuse to cooperate with it. Here is how you actually get a closet that fits and functions. Start with your actual room dimensions, not the ones you measure with a cheap tape. Stand against the wall where the wardrobe will sit and look at the floor. Most rooms have baseboards, uneven skirting boards, and flooring transitions that add up. Measure the width at the top, the middle, and the bottom of the wall. If those three numbers differ by more than a centimeter, your room is out of square and you need to adjust your plan accordingly. I once ordered a three-unit Pax run for a bedroom that turned out to be 12mm narrower at the baseboard level. The side panels would not close flush. I ended up using filler strips on both sides and lost 24mm of usable interior space. This happens more often than you would think.
Understanding Pax Frame Dimensions Before You Open the Planner
A standard Pax frame is 50cm, 75cm, 100cm, or 125cm wide. The depth is always 60cm for the standard series, and height options are 201cm, 236cm, or 239cm depending on the model. The frame itself takes up about 2.5cm on each side. So a 100cm frame actually provides roughly 95cm of interior width. The planner accounts for this, but it does not warn you about it in plain language. It just shows you the final configuration and expects you to trust the math. Here is the part nobody tells you. The Pax system uses a specific rail mounting method called the Optima hanging system. The vertical rails are anchored into the side panels, and the shelf supports click into pre-drilled holes along those rails. The planner lets you place shelves and drawers freely, but in reality you are limited by the rail hole spacing. If you try to put a shelf at a non-standard height, you will find there is no support hole for it. I once tried to customize a shelf height in the planner to exactly 112cm from the floor because I had a specific storage need. The planner accepted it. When the unit arrived, I could not actually install that shelf because the rail holes did not align. I had to go with 110cm and stack boxes instead. Check your rail specifications before you finalize anything in the software.
Practical Hacks That Actually Matter
First hack. Do not fill every single Pax frame with the same interior layout. Mix deep drawers in one section, hanging rods in another, and open shelving in a third. The planner pushes you toward uniformity, but uniformity is expensive and inefficient. A section dedicated to long coats needs 180cm of hanging height minimum. A section for folded sweaters works fine at 30cm per shelf. Plan each bay individually rather than applying one template across the whole unit. Second hack. The interior lighting packages sold by Ikea are decent but the wiring routing is a nightmare if you did not plan for it during the design phase. I installed Pax lighting in a bedroom project and had to drill through three side panels after assembly because the cables were not long enough to reach the power source. If you want lighting, decide where the transformer will live before you order. Leave a section unplanned or put a false back panel somewhere accessible. Third hack. Floor levelling. Pax frames come with adjustable feet, but the range is limited to about 25mm. If your floor is uneven by more than that, the doors will not align properly and the drawer slides will bind. I dealt with this on a project where the floor slope was approximately 8mm across a 3-meter run. I had to shim the feet with wooden wedges and then caulk around the base to hide them. The planner cannot account for this. You are on your own for that step.
Get the Full Details
Fourth hack. The Pax door widths do not always match the frame widths perfectly. There is a standard reveal gap built into the design, usually around 2mm on each door edge. When you have a wide opening, like 250cm, the planner will suggest four doors. Sometimes two doors look better, sometimes three. Try both configurations and compare the visual weight. Three doors on a 250cm opening can look blocky. Four doors spread the sightlines more evenly. This is subjective but it matters when the wardrobe is the dominant piece of furniture in a small room.
Common Pitfalls That Waste Money
One of the biggest mistakes people make is ignoring the door swing clearance. A Pax wardrobe with hinged doors needs at least 60cm of clear floor space in front of it for the door to open fully. If you have a narrow bedroom and the bed sits directly opposite the wardrobe, those doors will hit the bed frame. In that case, you should consider sliding doors or the Pax Drevning series which has a different hinge mechanism and requires less clearance. The planner will show you the doors open, but it does not simulate real-world obstructions. Measure the floor space in front of your planned wardrobe location before committing to hinged doors. Another pitfall involves the drawer depth. Standard Pax drawers are 64cm deep, which means they extend about 4cm past the front of the 60cm deep frame. If your wardrobe will be placed against a wall with very little clearance at the sides, those drawers might not open fully. I ran into this in a studio apartment where the wardrobe was flanked by two bookshelves with only 3cm gaps on each side. The drawers would hit the bookshelves before reaching full extension. I switched to shallower drawer units and accepted less storage capacity in exchange for functionality. Sometimes you have to compromise.
What the Planner Cannot Do For You
The Pax planner is fundamentally a configurator, not a design tool. It will not help you think about how you actually live. It will not suggest that you need more shoe storage because you own twelve pairs of boots. It will not remind you that a full-length mirror on the inside of a door changes how you use the wardrobe every morning. These are decisions that require you to stand in your actual room and imagine your daily routine, not click through menus in a browser. The planner also does not integrate well with third-party interior components. If you want custom inserts like jewelry trays, tie racks, or belt organizers from other manufacturers, you will need to measure everything yourself and fit them after the Pax frames are assembled. The planning software treats all accessories as if they come from Ikea's catalog. They do not always work interchangeably.
A Realistic Workflow That Saves Time
Open the planner and sketch out your basic layout. Do not spend more than twenty minutes on the initial configuration. Then print or screenshot the design and take it to your actual room. Hold it up against the wall with a tape measure in your hand. Check every dimension against the physical space. Adjust. Repeat until the numbers match your measurements within a centimeter. Then, and only then, place the order. When the boxes arrive, lay them out and count every component before you start assembling. Ikea packaging is generally reliable, but missing screws and damaged panels do happen. I have encountered both. If something is missing, do not attempt to improvise a replacement from hardware store parts. The Pax system uses specific fittings, and generic alternatives tend to fail within months under regular use. Contact Ikea support with your order number and they will ship the missing piece within a week in most regions.
When Pax Is Not the Right Choice
If your wardrobe space is highly irregular, with angled walls, sloped ceilings, or built-in alcoves, Pax is the wrong solution. The system assumes rectangular rooms with standard door and window placements. Custom cabinetry will cost significantly more but will utilize every corner efficiently. I worked on a project where the client had a closet alcove with a 15-degree angled wall. Pax frames could not follow that angle. We ended up ordering a bespoke carpentry job that fit the space perfectly. The Ikea option would have left a visible triangular gap along the entire length of the wardrobe. That gap would have collected dust and looked unfinished. In cases like that, the planner is essentially useless and you should consult a local cabinetmaker instead. Similarly, if you need a wardrobe taller than 239cm, Pax will not reach your ceiling. The system tops out at that height by design. I have seen people try to stack two Pax units vertically to achieve extra storage, but this is structurally unsound and not recommended by Ikea. The frames are not rated for that kind of load distribution. If you need more vertical storage, consider combining Pax with open shelving units from the same line, but keep them separate and anchored independently.
