When comparing IKEA PAX vs. Elfa for a reach-in closet, check the opening with the existing doors in place. A frame can fit between the side walls, while a drawer behind a return wall cannot pass through the doorway. Put the drawer where it can open fully, then decide what belongs in the space on either side.
Start with PAX if the selected frames and KOMPLEMENT organizers fit the cavity and work through the opening. Consider Elfa Classic if the wall can support the specified track installation and you want to rearrange compatible components later. Request a fitted plan when it can solve a specific access problem or recover storage you will use regularly.
This guide uses one illustrative U.S. bedroom closet. The layouts show how to compare reach-in closet systems before selecting parts or requesting prices. Actual product compatibility, installation requirements, and costs depend on the parts and conditions of your project. ALLURE publishes this guide and developed the illustrative custom layout.
Key Takeaways
- Measure the clear doorway with the existing doors open, as well as the cavity behind it.
- Give all three layouts the same hanging, drawer, shelf, and shoe storage tasks.
- Draw the most-used drawer at full extension, and check access to both ends of the hanging rail.
- Compare the same delivered or installed scope, with a named party for any work still unpriced.
IKEA PAX vs Elfa vs Custom Closets: The Short Answer
Plan A — PAX frames with KOMPLEMENT organizers
PAX organizes storage inside cabinet frames. For the retained-door example, plan an open internal arrangement and leave the room-side closet doors in place. Start with the available frame sizes, then select compatible shelves, rods, or drawers. IKEA’s U.S. guide explains how to select frames and KOMPLEMENT organizers. Use the documentation for each selected product when checking actual fit and assembly. IKEA U.S. PAX Design Guide
The frame divisions determine where each internal organizer can go. If a drawer bay falls behind the side return, test whether the drawer can move to a different frame and whether the hanging space still serves the same garments.
Plan B — Elfa Classic with a wall-mounted track
For this comparison, use the wall-mounted Classic configuration with a top track and hanging standards. Check the selected shelves, rods, and drawer components together. The instructions for the 4-foot Classic kit show how that kit’s track, standards, and brackets fit together. Consult the instructions for the configuration you actually intend to buy. The Container Store Elfa Classic Kit Instructions
Draw the usable mounting wall and the intended drawer bay. Check the selected component widths and mounting requirements before moving a bay on the plan. Adjustability can help when storage needs change, provided the new arrangement works with the track, components and wall.
Plan C — A fitted layout for the same opening
Ask the cabinet team to draw one fitted arrangement with partitions, rods, shelves, a drawer bay and any finishing pieces. Specify the location of the drawer bay in relation to the clear opening. Keep the same room-side doors and open internal configuration. If the proposal adds doors or changes the jamb or wall, record that work as a separate alternative.
Start With the Same Reach-In Closet
Measure the cavity and doorway separately
Record the finished width, depth, and height of the closet. Measure the clear opening with the doors in the position you will actually use. Mark the side returns, jamb, baseboard, door hardware, and any floor or wall irregularities. A nominal door size leaves out the space a leaf, handle, or track can occupy when the doors are open.
In the illustrative plan, the cavity is 84 inches wide, and the clear opening is 48 inches wide. Measured from the left interior wall, the clear opening runs from 19 to 67 inches. The retained doors and side returns stay in the same positions in all three drawings. These are example room dimensions. A real order also needs verified depth, height, wall conditions, and door movement.
Give each layout the same storage brief
Reserve space for long garments, short hanging, frequently used folded clothing, shelf storage, and everyday shoes. Use the same representative items to test each plan. Measure the longest garment on its hanger and the tallest pair of shoes. Record which items can live at the sides and which need to be reached from the center every day.
Compare the Three Layouts Side by Side
Draw the storage against the fixed opening
Place the PAX frame sides, Elfa standards, and custom partitions on elevations drawn to the same scale. Overlay the clear opening on each elevation. Show the locations of long and short hanging, drawers, and shoes. Mark the outline of the existing doors in their open position and keep the same side returns.
Use the elevations to spot different constraints. A PAX bay may suit the opening once the frames are positioned, but the drawers still have to fit inside a compatible frame. The Classic drawer assembly needs a supported position that works with the selected system. A custom drawer can put the drawer bay inside the opening, while the partitions and any finishing pieces still occupy space.
Follow a drawer all the way out
Assume a proposed drawer has a 24-inch-wide travel envelope. This is an illustrative envelope, not a PAX or Elfa product dimension. A drawer placed from 12 to 36 inches from the left wall overlaps the side return, which ends at 19 inches. Shifting that envelope to 26 through 50 inches puts it inside the opening in this width-only check.
Test the revised bay in plan view. Show the selected drawer at full extension, including the front and handle, with the door open. Check that it passes the jamb and leaves enough space for the person using it. Then see what moved to make room. A drawer that works in the center may use space previously assigned to long hanging. Verify actual drawer travel, bay width, and door projections before approving any configuration.
Check Usable Storage Beyond Overall Width
Count what can be reached and removed
For hanging, measure the usable rod length and the clear drop below it. Put a representative garment at the outer end and check whether you can remove it without pushing the rest of the clothes aside. Keep items used daily within the part of the rail you can reach through the opening. An outer section can still serve occasional storage if you can retrieve the items when needed.
For drawers, compare internal width and depth and the portion you can access with the door open. For shelves, check the reach to the back and whether items can clear the jamb on the way out. Count shoe positions using the same footwear. If a proposed layout cannot meet a task, write down the reason rather than counting nominal capacity.
| Task | PAX + KOMPLEMENT | Elfa Classic | Specified custom layout |
|---|---|---|---|
| Long and short hanging | Check rod positions within the chosen frame bays and access through the opening. | Check compatible rod positions, hanging drop, and reach at both ends. | Check accessible rod length after partitions and the drawer bay are placed. |
| Drawer access | Draw travel for the selected organizer in its frame. | Draw travel for the selected drawer assembly at its mounting position. | Confirm internal size and travel from the proposed drawing. |
| Shoes and folded items | Count reachable places within selected frames. | Count reachable places at planned shelf or rack depths. | Check reachable shelf depth behind the side returns. |
| Existing doors | Retain. Check any frame or drawer conflict. | Retain. Check component projection. | Retain. Record any proposed alteration separately. |
Compare Installation and Future Changes
Confirm fixing, access and preparation
For a PAX layout, check the instructions for the selected frame, including anchoring and any assembly clearance. Show the baseboard and retained door frame on the plan and check how components get into the cavity. Have the installer confirm how the specified fixing relates to the actual wall.
For Elfa Classic, identify the selected track and standards, the mounting surface and any preparation the installer requires. Review the instructions for the exact configuration and substrate. For the fitted proposal, request drawings showing how the partitions, fillers, and exposed edges meet the walls and how the units will be secured. Across all three, record who measures, who checks the wall, and what preparation belongs in the quote.
Test one likely change
Imagine converting part of the short-hanging area to shelf storage later. Identify the parts you would move or add in each layout, then check compatibility and availability. A shelf adjustment within a suitable bay is a different job from moving a frame, track, or fixed partition. Include the work needed for the specific change you expect rather than assuming the entire system can be relocated.
Compare Costs Only at the Same Scope
Choose one delivery or installation endpoint
Compare all three at the same point, such as delivery to the residence or complete installation inside the retained opening. For each, itemize frames or tracks, rods, shelves, drawers, hardware, finish pieces, delivery, assembly, and installation. List wall preparation, baseboard work, and any door changes separately. Check whether a bundled line already covers a task before adding it again.
Keep unpriced work visible
For real quotes, use the same destination ZIP code, currency, quote date or validity period, and tax treatment. Ask each seller or installer to mark every line included, separately priced, excluded, or pending. A delivered component list can be compared at a delivered endpoint. To compare it at an installed endpoint, obtain the labor and site work scope first. The example below is a checklist for collecting that information.
| Line item | PAX | Elfa Classic | Fitted custom |
|---|---|---|---|
| Main components | Frames and selected organizers | Track, standards and selected organizers | Partitions, interiors, drawers and hardware |
| Finish and fixing | Confirm listed pieces and mounting requirements | Confirm specified fixing and wall preparation | Confirm fillers, edges and fixing scope |
| Delivery and installation | Confirm delivery, assembly and anchoring | Confirm delivery, mounting and assembly | Confirm delivery, fitting and installation |
| Site changes | Identify any work at the baseboard or doorway | Identify any work needed to prepare the mounting wall | Identify any separate trim, door, or wall work |
Which Option Fits Your Project?
Start with PAX when the opening works with the frames
Place the selected frames on the elevation and check each frequently used organizer against the retained doors. If the drawer position and hanging zones serve the brief, obtain the complete part list and installation scope. Reconsider the arrangement if accessing a daily drawer requires moving a door beyond its normal position.
Start with Elfa Classic when you expect to rearrange storage
Check that the selected wall-mounted configuration serves today’s tasks and that the wall and fixing requirements can be confirmed. Then map one future change using compatible components. If the drawer bay needs to move to clear the jamb, check the effect on the track layout and hanging storage.
Request a fitted plan when it solves a visible problem
Ask the supplier to show the exact improvement: a drawer moved into the clear opening, a reachable end shelf, or more useful hanging behind the same doors. Compare that improvement with any extra fitting work. Keep the standard arrangement in consideration when it meets the same access and storage requirements. For decisions about furniture elsewhere in the room, see the broader ALLURE Built-In vs Freestanding Furniture Guide.
FAQs About IKEA PAX, Elfa and Custom Reach-In Closets
Can IKEA PAX fit behind existing closet doors?
It can if the selected frames fit the cavity and can be assembled and anchored as required. Check the clear opening with the doors open. Test drawers and other pull-outs through that opening before ordering.
Can Elfa Classic drawers clear my closet opening?
Check the exact drawer and its intended mounting position. Draw the front at full extension and compare it with the open door, jamb, and side return. A drawer that fits within the wall-mounted layout may still need a different position to be used comfortably.
When does a custom reach-in closet make sense?
It makes sense to request a fitted plan when you can identify an access or storage problem worth solving. Ask the supplier to show how the proposed layout changes drawer travel, reachable hanging space, or use of a wall end.
Which closet system is easier to change later?
Compare the change you expect to make. Check which shelves, rods, or organizers can move within the specified layout and which changes require new parts, a different fixing position, or a rebuilt bay.
Start With the Drawer You Use Most
Before comparing prices, test your most-used drawer and hardest-to-reach hanging zone on all three plans. If one option improves access, ask the supplier to show that difference on the drawing and identify which parts and work it takes to deliver it.
