Before choosing an insert

## Measure the opening as well as the space inside

Record the smallest clear opening, usable shelf bays and assembled hanging drop. Then check hinges, door overlap and the path of anything that pulls out. The widest internal measurement is rarely enough on its own.

A wardrobe organiser has two jobs: fit where it sits and remain reachable through the doors. A wide bin can fit on a shelf yet be awkward to lift past a hinge. A hanging shelf can clear the floor but collide with the clothes beside it. Measuring those movements first helps you choose the right type rather than just the right advertised size.

Empty the bay you want to improve and leave the wardrobe installed as its instructions require. Use a tape measure and a sketch with separate notes for width, depth and height. Photograph the fittings for your own reference if useful, but do not estimate dimensions from the photograph.

## Start with the smallest clear door opening

Open hinged doors to the position the room actually allows. A bedside table, wall or another door may prevent the full swing shown in an assembly drawing. Measure between the nearest projecting parts at the height where the organiser will pass through.

Look for hinges, handles on the inside, catches and a centre divider. Record local restrictions rather than subtracting one assumed allowance from every shelf. A shelf below a hinge can have a different usable opening from the shelf above it.

With sliding doors, measure the exposed opening after each door moves into its normal position. The wardrobe’s total internal width may be much larger. A pull-out basket must sit behind a usable opening, not behind the overlapping part of the doors.

Check the accessible opening, the complete hanging drop and local hinge projections. Illustrative drawing, not an installation plan.

## Measure shelf bays where the organiser will sit

Record shelf width between the panels or uprights, usable depth from the front edge to the back, and height to the lowest obstruction above. If the door closes across the shelf front, include the space taken by its fittings. Check the same dimensions at the front and rear if the bay tapers or is not square.

For a pull-forward bin, the outer dimensions decide whether it fits the shelf. The inner dimensions decide whether it holds your folded stack. A lid, handle or rolled rim can be wider than the base. Allow access to the part you need to grip without treating a tiny numerical difference as guaranteed handling room.

## Compare the bay, the local opening and the row

We calculated an illustrative 80 cm internal span with a 3 cm hinge intrusion at the relevant height. The local opening is 77 cm. If you have already measured 77 cm between the nearest obstructions, use that figure directly; subtracting the hinge again would count it twice.

The table allocates 30 cm to each item and a chosen 2 cm gap at both outer edges and between items. The 30 cm reference matches the listed body width of each SONGMICS hanging organiser below, but the gaps and wardrobe are illustrative. Soft loaded sides, attachment placement and rail capacity need separate checks.

Swipe to compare the complete row allocation.

Illustrative 77 cm local opening. All figures in centimetres; the remaining width includes the chosen gaps.

| Number of 30 cm items | Bodies only | Allocated gaps | Total allocation | Remaining width |
| --- | --- | --- | --- | --- |
| 1 | 30 | 4 | 34 | 43 |
| 2 | 60 | 6 | 66 | 11 |
| 3 | 90 | 8 | 98 | \-21 |

**The main decision.** Two 30 cm bodies alone leave 17 cm within the local opening. The chosen side and middle gaps use 6 cm, leaving 11 cm unallocated. Three bodies exceed even the 80 cm interior before gaps. The row allocation does not establish how an individual container passes a hinge.

### Keep the hinge deduction at the height where it applies

The gold strip is the illustrative 3 cm intrusion. The two green bodies occupy 60 cm; the labelled 77 cm is the local opening after that intrusion. Smaller containers can be removed separately, so do not require the whole row to pass through as one rigid unit.

A sliding door can leave a 77 cm opening in the wrong position for a fixed basket. Record the left and right edges of that opening, not only its width.

Horizontal scale: 3 drawing units per centimetre. Body heights and hinge height are schematic. This is a width allocation, not an installation plan.

### Separate listed body height from complete hanging drop

Suppose the distance from the rail attachment reference to the lower obstruction is 96 cm. Subtracting a listed 90 cm body height gives a 6 cm difference, but that does not establish the remaining clearance if the attachment is outside the body measurement. The complete drop must use the same top reference as the available distance.

Swipe to compare known and unknown assembled measurements.

Available distance: an illustrative 96 cm. The 94 and 98 cm drops are hypothetical alternatives, not SONGMICS specifications.

| Measurement available | Complete drop | Remaining distance | What the result establishes |
| --- | --- | --- | --- |
| Body height only: 90 cm | Unknown | Not assessed | The 6 cm body-only difference is not confirmed clearance |
| Hypothetical measured complete drop | 94 | 2 | 2 cm dimensional difference; movement and loading remain to check |
| Hypothetical measured complete drop | 98 | \-2 | Exceeds available drop by 2 cm |

The same discipline applies to shelf depth: take the supported bay depth and the organiser’s complete front-to-back dimension at that position. Do not use a wardrobe’s advertised outside depth. For a hanging unit, check how the attachment positions the body relative to the back panel and closed doors. A 30 cm body depth alone does not determine where its front will finish.

Keep frame-specific baskets on a separate compatibility sheet. Hole positions, runners, door alignment, full extension and supported loads are additional inputs; a positive width or drop difference cannot supply them.

An adjustable shelf riser introduces its own legs and shelf thickness. Measure the usable gaps above and below it, not just the wardrobe bay. If the aim is to keep piles upright, a divider may use less vertical space than an extra shelf. Our [wardrobe organisation hub](https://spacemadeuseful.co.uk/wardrobe-organisation/) explains those different approaches.

## Check rail fit and the complete hanging drop

Measure from the attachment point on the rail to the floor, lower shelf or drawer below. Then compare with the organiser’s complete assembled drop, including hooks or straps. Also record the distance from the rail to the back panel and the door so the shelves do not get compressed between them.

The SONGMICS five-shelf example uses a 30 × 30 cm footprint and a listed 90 cm body height. Check the exact assembled hook-to-bottom drop against your bay; do not simply assume the hooks are included in the 90 cm. Leave the contents within the intended compartments rather than loading piles above their openings.

### SONGMICS hanging organisers, set of 2

Each five-shelf organiser uses a 30 × 30 cm footprint beneath the rail. Open compartments put folded clothes at different levels.

**Outside · cm**: 30 × 30 × 90

**Access**: Open compartments

**In the pack**: Two organisers

**What to check** Confirm the complete assembled hook-to-bottom drop against your bay. Each shelf is rated for up to 2 kg, with 10 kg total per organiser. Check the wardrobe rail’s capacity.

Hanging shelves take up rail width that clothes previously used. Mark their width with a strip of card or an empty clothes hanger arrangement before ordering. Check the rail’s documented capacity and its supports. A product’s own load limit is a separate question from whether your rail can carry it alongside the existing clothes.

## Treat fitted baskets and rails as a compatibility check

A universal lift-out container and a runner-mounted wardrobe basket need different evidence. For a mounted system, confirm the exact wardrobe model, frame dimensions, hole pattern, supplied runners, compatible doors and mounting instructions. Matching width alone cannot establish that a fitting is suitable.

Nominal sizes can describe the wardrobe system rather than the accessory. For example, a tray sold for a particular 50 × 58 cm frame is not necessarily 50 cm wide or 58 cm deep. Use the accessory’s own outside dimensions and its stated frame compatibility. Do not transfer measurements from another colour, generation or tray-and-divider combination.

Check a basket’s full pull-out path in front of the wardrobe as well. A bed may block it before it reaches a useful opening. Never reposition hinges, remove required supports or alter runners to accommodate an unsupported accessory.

## Keep a bay-by-bay measuring sheet

Record the measurements separately for each bay you want to use:

1.  Clear opening at the intended height, with doors in their real usable positions.
2.  Shelf width, depth and height, including lips, hinge projections and catches.
3.  Rail attachment details, available width and complete hanging drop.
4.  Floor space needed to withdraw a bin, basket or drawer.
5.  Exact model compatibility and any documented support or load requirements.

Use a cardboard footprint for a bin or riser and try its retrieval route. For soft organisers, remember that a filled compartment can bulge. Start with the empty organiser when it arrives, check closure gently and load it only after confirming the fit.

If you are moving small accessories out of the wardrobe, measure the receiving drawer as well. Our [drawer measuring guide](https://spacemadeuseful.co.uk/measure-for-drawer-organisers/) covers the different closing-height restrictions. For rigid containers on a shelf, use the [shelf and box measuring guide](https://spacemadeuseful.co.uk/measure-shelves-for-storage-boxes/).

Once you have your measurements, compare [shelf risers](https://spacemadeuseful.co.uk/best-wardrobe-shelf-inserts/), [hanging shelves](https://spacemadeuseful.co.uk/best-hanging-wardrobe-organisers/) and [pull-out baskets](https://spacemadeuseful.co.uk/best-pull-out-wardrobe-baskets/). If the panel overlaps the part of the bay you want to use, start with the [sliding-door layout guide](https://spacemadeuseful.co.uk/organise-a-wardrobe-with-sliding-doors/).

## Questions before you choose

### Should I use the wardrobe’s outside or inside dimensions?

Use the usable interior and the opening the organiser must pass through. Outside furniture dimensions include panels, doors and sometimes trims, so they cannot establish the available storage bay.

### How do I measure around hinges?

Open the door to its normal usable position and record where each hinge projects into the bay. Check the organiser’s route past it, including when a drawer or basket is pulled out.

### Does a hanging organiser’s stated height include its hooks?

Do not assume it does. Compare the complete rail-attachment-to-bottom measurement with the same reference in your wardrobe. Check the rail and support load documentation separately; the organiser’s rating does not establish rail capacity.

### Will a PAX accessory fit another wardrobe of a similar size?

Similar dimensions do not establish compatibility. Frame-specific fittings depend on mounting positions, runners, fasteners and door geometry. Use them only with a system the manufacturer supports.

### How do sliding doors affect pull-out baskets?

The open door leaves only part of the interior accessible. Check that the complete basket and its runners line up with that opening throughout the pull-out movement.

## How the examples are used

Product dimensions refer to the exact catalogue variant. The 80 cm bay is an illustrative calculation. Frame-specific accessories require their own compatibility and fitting instructions; this guide does not treat a similar-sized wardrobe as an approved substitute.

Our comparison uses the inputs below and the stated formulas. Room dimensions and handling allowances are illustrative; named product dimensions are kept separate from them. Analysis prepared November 2026.

-   Local opening = measured internal span − intrusion at the same height and position.
-   Allocated row width = item count × outside width + (item count + 1) × chosen gap.
-   Remaining drop = rail-attachment-to-obstruction distance − complete assembled attachment-to-bottom drop.

Calculations use unrounded inputs; displayed results are rounded to two decimal places where necessary.

-   The 80 cm span, 3 cm local intrusion, 2 cm gap and 96 cm available drop are illustrative. They are not manufacturer clearances.
-   For an opening already measured between obstructions, do not subtract the hinge a second time. Other hinges can occupy different heights.
-   The row arithmetic shows a front-view allocation. Independent containers pass through the opening individually; it does not require the whole row to be carried out together.
-   A sliding door opening can be offset. Width alone does not establish alignment with a fixed basket or hanging organiser.
-   Catalogue reference is two five-shelf organisers, each 30 × 30 × 90 cm. The 90 cm body height does not establish complete hook-to-bottom drop.
-   The 94 and 98 cm complete drops are separate hypothetical examples, not alternative specifications for the SONGMICS product. Attachment compatibility, bulging, rail load and floor clearance remain separate checks.
