Installing custom storage requires exact site dimensions to guarantee seamless operational movement and proper structural fit. This comprehensive guide outlines the precise steps needed to calculate your opening width and opening height across 3 distinct points, accounting for sloping ceilings and out-of-plumb side walls. It details how standard 100mm track depth requirements alter the usable depth inside your wardrobe frame, ensuring internal drawers, hanging rails, and pull-out accessories clear the panel overlaps completely.
We examine the physical necessity of establishing a level floor to prevent door drift, along with practical structural adaptations for older properties with decorative coving or deep skirting boards. By following this technical measuring approach, property owners and fitters can eliminate alignment misfits, avoid costly timber re-orders, and organise their internal wardrobe components to align perfectly with made-to-measure sliding doors.
Measuring a domestic bedroom for custom built-in storage often presents hidden technical challenges because UK properties rarely feature perfectly straight walls, flat floors, or square plaster corners. Small variances in wall plumbness quickly complicate frame installation, leading to binding panel mechanisms or unsightly gaps around your finished wardrobe casing.
Failing to account for these structural irregularities can ruin an installation, as British standard BS 6100 highlights that typical floor and wall tolerances across domestic properties vary by up to 15mm over a 2 metre span. Without accurate site checks prior to ordering, internal drawers will hit the front sliding system, resulting in re-fitting delays and material waste costing upwards of £350 per room.
Adopting a systematic multi-point measuring method allows you to identify structural slopes early and specify the exact strike plates or floor liners needed. Factoring in a dedicated 100mm track depth alongside a verified level floor ensures your made-to-measure panels glide smoothly while internal layout fittings remain completely accessible.
KEY TAKEAWAYS
- Measure opening width and opening height across 3 separate points along the top, middle, and bottom to identify structural variances before ordering made-to-measure panels.
- Reserve at least 100mm of internal frame depth for the top and bottom track depth so internal drawers and pull-out trays open fully without fouling the doors.
- Prepare a level floor base using timber liners or floor packers to stop sliding doors rolling open automatically on sloped or uneven room surfaces.

Aligning interior storage modules with door overlap zones
Measuring Door Overlap and Dead Zones
Door overlap occurs where sliding doors cross paths, creating a restricted zone that partially blocks internal access. Accurately mapping these dead zones ensures your built-in storage remains fully accessible when doors sit in their open positions.
When installing made-to-measure sliding doors, the door stiles create an overlap area typically measuring between 25 mm and 75 mm wide. If you place a vertical divider directly behind this door overlap, accessing items stored behind that central point becomes awkward. You must calculate the exact position of the door stiles on their 2-runner or 3-runner tracks before finalising your internal layout. In 3-door or 4-door installations, multiple overlap points exist, which reduces the total accessible aperture by up to 10% compared to standard hinged doors. Marking out these crossover zones on your floor track using masking tape gives a clear visual guide before fixing any internal partition panels into place.
Position Internal Tower Units Correctly
Internal tower units must align cleanly with the centre of individual door panels rather than the junction where panels cross over. Positioning storage columns within the clear opening width prevents shelves and hanging rails from being obscured by door frames.
For a 2-door configuration, each door slides across 50% of the opening width, leaving roughly 45% usable aperture space per side due to the door overlap. Divide your wardrobe cavity into equal sections matching the clear aperture dimensions rather than the overall frame width. When working with 3-door systems, ensure the central module aligns with the middle door when pushed fully to 1 side.
To position your interior frame correctly during assembly, follow this simple sequence.
1. Measure the total opening width and subtract the manufacturer-specified door overlap dimension.
2. Divide the remaining dimension by the number of doors to find the true clear aperture per door.
3. Fix your vertical partition walls strictly within these calculated clear aperture zones.
Ensuring Unobstructed Drawer Clearance
Drawer clearance requires a minimum buffer space to ensure internal drawers pull out completely without striking the rear edge of overlapping doors. Incorporating filler panels or positioning drawer stacks away from door stiles eliminates expensive mechanical collisions during daily use.
Pull-out components like shoe racks and internal drawers are especially vulnerable to door overlap obstructions. Soft-close mechanisms and proud handle designs add extra depth, meaning a drawer stack positioned 10 mm too close to a door overlap zone will snag on the door stiles. Always install a 50 mm timber spacer panel or position drawer columns centrally within the primary door opening to guarantee 100% operational clearance. If you plan to install full-extension wire baskets, add an extra 25 mm margin of safety to accommodate minor track flex or slight door misalignment over time.
Planning hanging space height for different clothing items
Calculating Clearances for Full-Length Drop Garments
Full-length drop garments like coats and evening dresses require a minimum vertical clearance of 1600 mm to prevent hem creasing. Setting your hanging height correctly ensures long items hang cleanly clear of the bottom track of your made-to-measure sliding doors.
When you plan internal carcase space for an extended drop, a single hanging rail positioned near the top of the interior carcass is the standard layout choice. This arrangement leaves sufficient space below for secondary storage options like low-profile shoe racks or slide-out drawers.
To verify your setup, measure from the underside of the top shelf down to the top of the floor runner. Standard overcoats typically require 1400 mm, while long dresses often need up to 1700 mm. Allowing an extra 50 mm clearance above the rail ensures standard coat hangers fit comfortably without scraping the top partition.
Maximising Vertical Capacity with Double Hanging Rails
Installing a double hanging rail configuration effectively doubles your storage density for shorter items like shirts, jackets, and folded trousers. Each tier requires a designated hanging height of 900 mm to 1050 mm to allow garments to hang freely.
This dual-tier layout works exceptionally well in standard ceiling heights of 2400 mm. To organise a balanced internal layout before installing your sliding wardrobe doors, follow this 3-step measuring routine.
1. Measure 2000 mm up from the base floor to locate the position for the upper single hanging rail support brackets.
2. Secure the lower rail at roughly 1000 mm from the base floor, providing equal vertical clearances for both levels.
3. Test the clearance with your longest everyday shirt or blazer to confirm hems remain clear of lower obstructions.
By using this approach, you maximise your available internal volume while maintaining quick visual access to daily workwear.
Adjusting Heights for Specific Wardrobe Track Positions
Sliding door runner mechanisms reduce the internal functional height and overall access depth by up to 100 mm. Planning your internal wardrobe architecture with this structural deduction in mind prevents hanging clothes from catching on moving door panels.
Positioning your internal partitions and rails requires careful alignment with the overall aperture dimensions. Built-in sliding frames normally absorb 50 mm at the head frame and another 30 mm to 50 mm at the floor track. Always subtract these frame dimensions from your total room height before cutting panel supports or fixing rail end sockets. Ensuring your clothes sit completely behind the door track overlap eliminates friction and prevents long-term fabric damage when sliding doors bypass one another.
Integrating shelving units and shoe storage efficiently
Optimising Vertical Space With Storage Towers
Modular storage towers utilise full ceiling heights to create structured zones for folded garments and bulky gear. Setting a continuous top shelf above these units secures long-term structural rigidity whilst keeping seasonal items cleanly out of sight.
Floor-to-ceiling framing ensures zero wasted capacity inside the main carcass. By installing storage towers directly beneath the top shelf, you establish a solid framework that aligns perfectly with the width of your sliding panels. This layout prevents dead space behind door stiles and ensures every millimetre of interior depth works hard. Adding a wide top shelf running the full span of your wardrobe gives you 1 dedicated platform for large suitcases, spare pillows, and heavy winter bedding.
Positioning Adjustable Shelves Behind Door Overlaps
Placing adjustable shelves away from central door meeting points prevents frustrating access bottlenecks during daily use. Aligning shelf edges with outer panel boundaries guarantees clear line-of-sight access to your folded clothes without catching on internal runners.
When mapping out your interior, matching internal shelf columns to the door overlap zones is essential for daily convenience. If a shelf sits directly behind where 2 doors overlap, reaching items becomes awkward. Adjustable shelves allow you to alter vertical spacing by 32 mm increments as your storage requirements shift across different seasons. Follow this 3-step alignment routine when setting up your shelving internal framework.
1. Measure the exact point where the sliding door tracks overlap inside the track channel.
2. Mark out fixed vertical uprights at least 50 mm clear of these overlap boundaries.
3. Secure your adjustable shelves using recessed shelf pegs to ensure complete stability under 20 kg loads.
Integrating Pull-Out Shoe Racks For Seamless Access
Dedicated shoe racks placed at lower levels prevent footwear from cluttering floor space and blocking door guides. Choosing extendable runners allows full-depth visibility while protecting bottom door tracks from grit and dust.
Angled shoe racks maximise storage capacity by fitting up to 4 pairs of shoes across a standard 600 mm width. Placing pull-out mechanisms on soft-close runners prevents footwear from shifting when sliding doors move back and forth. Ensure you leave a minimum clearance of 100 mm between the bottom rack and the floor track so dust does not build up near the mechanism.
Integrating specialised shoe racks alongside low-level drawers creates a neat footwear zone that keeps everyday pairs organised and instantly accessible.
Using the online door designer to test your interior layout
Simulating Panel Alignment with Internal Dividers
An online door designer allows you to map out exact panel overlaps against your internal uprights before committing to manufacture. This digital testing step prevents structural obstructions and ensures full access to internal drawers and hanging spaces.
When designing a bespoke wardrobe, your internal vertical dividers must line up cleanly behind the door frames. If a divider sits directly behind a panel join, opening a door leaves the shelf space partially blocked. Using a digital design tool lets you toggle through different panel configuration options in real time.
Follow this 3-step verification routine to check your alignment online
1. Enter your total opening width and height in millimetres into the software tool.
2. Select a 2-door, 3-door, or 4-door panel configuration to view the resulting opening gaps.
3. Overlay your custom interior drawer columns against the visible opening widths to confirm total clearance.
Visualising Door Overlaps and Access Angles
Configuring your sliding doors virtually reveals hidden dead zones where door frames obscure internal components. Adjusting your panel configuration online ensures smoothly operating drawers and accessible hanging rails behind every door section.
Sliding doors run on parallel tracks, meaning 1 door always sits behind another. The thick edge profile of structural door frames can reduce usable aperture width by up to 80mm when opened fully. If you place pull-out shoe racks or deep drawers right next to an outer wall, a frame overlap can block the mechanism entirely.
When selecting panel materials such as glass or mirror finishes, ensure your specification uses 4mm safety-backed glass rather than toughened glass. Made-to-measure safety-backed glass complies with British standards (EN 12600) and allows panels to be cut precisely to size in the factory. Note that the protective safety film on the back of the glass may show minor visual imperfections like slight bubbles or creases; these are standard, do not affect impact resistance, and remain hidden from the front face of the door.
Testing your layout in an online door designer highlights these overlap zones and material requirements early on. You can re-position internal gables or alter panel widths by 50mm to 100mm, creating a perfectly tailored match between your outer aesthetic and your custom interior functionality.
Optimising Track Depths for Internal Storage
Inputting precise millimetre measurements into the online door designer locks in accurate door-to-frame ratios for your space. This eliminates installation errors by aligning your custom interior directly with the outer sliding track system.
A standard 2-runner track system requires around 100mm of internal depth solely for door hardware. Homeowners often forget to subtract this track space when planning internal shelf depths.
By adjusting your internal shelf cut-backs online, you ensure clothing hangs clear of the moving doors. This simple check protects delicate fabrics from catching on low-profile door frames while maintaining a sleek overall finish.
Frequently Asked Questions around Made To Measure Sliding Wardrobe Doors
How Much Internal Depth Do You Need For Made To Measure Sliding Wardrobe Doors?
You need a minimum internal depth of 560 mm to ensure your clothes hang comfortably without touching the sliding doors. 75-90 mm of this total depth is dedicated to the top and bottom running tracks, whilst 500 mm accommodates standard coat hangers.
If your room layout only allows for a 500 mm overall depth, you will need to fit pull-out front-facing rails instead of traditional side-to-side hanging bars.
Should You Install The Internal Wardrobe Layout Before Or After The Sliding Doors?
You should always install your internal wardrobe layout before fitting your made-to-measure sliding wardrobe doors. Installing internal storage first gives you full access to secure shelves, hanging rails, and drawer units directly to back and side walls without working in cramped spaces.
Once your internal storage components are securely fitted, you can install the bottom and top track sets to seal the wardrobe enclosure.
How Do You Align Internal Shelves With Sliding Door Overlaps?
You align internal storage by positioning drawer units and dividers directly behind the door overlaps so they remain fully accessible. Made-to-measure sliding doors overlap when opened, which creates narrow dead zones behind the central door sections.
Planning your vertical uprights to match these overlap points prevents drawers from striking the door frames when pulled open.
What Is The Minimum Width For A Made-to-Measure Sliding Wardrobe Door?
The minimum recommended width for an individual made-to-measure sliding wardrobe door is 500 mm to maintain proper stability on the track. Doors narrower than 500 mm tend to derail or twist during daily use because the door height creates an unstable aspect ratio.
For maximum running smoothness, aim for door widths between 600 mm and 1200 mm across your opening.
Can You Install Made To Measure Sliding Wardrobe Doors On Carpeted Floors?
Yes, you can fit sliding wardrobe doors over carpet, but you must fix a floor-clearing timber liner beneath the bottom track first. Fixing the bottom track directly onto soft carpet causes the metal track to flex under heavy door loads, which leads to sticky door movement.
A sturdy 90 mm wide timber liner screwed directly into the floorboards creates a flat, durable surface for smooth door operation.
How Much Overhead Clearance Is Required For The Top Track Assembly?
If your ceiling height varies by more than 5 mm across the opening width, install a level timber header block to correct the gap before fitting the track.
How Do You Calculate The Number Of Doors Needed For A Wide Opening?
You calculate door numbers by dividing your total opening width by 2 or 3 depending on your desired internal access and door panel weight. Openings wider than 2.5 metres typically require 3 or 4 doors to ensure individual door panels remain light and easy to glide.
A 3-door configuration offers excellent flexibility, giving you access to 33% of your wardrobe layout at any one time. However, with a triple track (available in our aluminium ranges), you can open up two-thirds of the space at once.
What Internal Distance Is Required Between Hanging Rails And Back Walls?
You must allow a minimum distance of 300 mm from the back wall to the centre of your hanging rail. This positioning stops bulky winter coats or suit jackets from brushing against the rear surface or catching on the front sliding track.
For double hanging sections, allow 1000 mm of vertical drop for shirts and 1500 mm for long dresses.
Are Built-In Drawers Compatible With Soft-Close Sliding Door Systems?
Yes, built-in drawer units are fully compatible with soft-close sliding door systems provided the drawers do not extend beyond the track line. You must set drawer fronts back by at least 25 mm from the inner edge of the sliding door track to prevent collisions.
Soft-close mechanisms cushion the door travel during the final 50 mm of closure, protecting internal drawers from impact.
How Do You Level Wardrobe Interiors On Uneven Floor Surfaces?
You level wardrobe interiors on uneven floors by installing adjustable levelling feet or cut-to-size floor liners beneath the interior base panels. A level base is essential because made-to-measure sliding doors require a flat bottom track to operate correctly over a 10 to 15-year lifespan.
Use a spirit level across the full floor span and pack low areas with high-density timber shims before attaching track work.
