Six decades of design, millions of units, and still the most common add‑on question: Which doors fit? Here are the core specifications at a glance.
| Item | Value |

The pattern: OXBERG doors are purpose‑built for post‑2014 BILLY units, and they come in two widths that match the narrow and medium bookcases. For wider units, you use multiple doors or consider custom solutions.
What doors are compatible with an IKEA BILLY bookcase?
IKEA OXBERG doors overview
- Glass doors with tempered glass
- Solid doors in white, black‑brown, and birch finishes
- Hinges allow horizontal and vertical adjustment
- Compatible with BILLY bookcases purchased after spring 2014
The OXBERG series is the only officially supported door line from IKEA. One door fits a nominal 15¾″ BILLY, two doors fit a nominal 31½″ BILLY. For the 40‑cm and 80‑cm widths, the principle is the same: one door per 40‑cm bay.
Owners of BILLY units bought before spring 2014 cannot use standard OXBERG doors without modifying the side panels. The hole pattern changed that year.
The implication: if you have an older BILLY, you either accept custom drilling or seek third‑party doors that fit the vintage hole pattern.
Custom door options
- DIY doors require drilling and hinge alignment
- Third‑party doors exist on marketplaces but may need adjustments
- Custom push‑to‑open mechanisms can be retrofitted
Custom doors allow unlimited finish options but require a hinge kit and precise alignment. The trade‑off: uniqueness versus installation effort.
Compatibility with different BILLY widths
- 40‑cm unit: 1 OXBERG door
- 80‑cm unit: 2 OXBERG doors
- 120‑cm unit: requires 3 OXBERG doors or custom wide door
The pattern: OXBERG doors scale linearly with the bay width. The 120‑cm model is the only common size without a perfect official door match — here, DIY or multiple doors are the solution.
How to install doors on a BILLY bookcase?
Tools and materials needed
- OXBERG doors and hinge kit
- Phillips screwdriver
- Level
- Drill (for custom doors)
- Wall anchoring kit
Step‑by‑step installation for OXBERG doors
- Remove BILLY shelves and assemble the bookcase per IKEA instructions.
- Securely anchor the bookcase to the wall using screws and wall plugs suitable for your wall material.
- Attach mounting brackets to the top and bottom of the door frame using the supplied screws.
- Align brackets with the existing shelf‑hole pattern (post‑2014 units have predrilled spots).
- Hang the doors and close them to check alignment. Use the hinge adjustment screws to level the door horizontally and vertically.
- Reinstall shelves and verify clearance.
Tips for DIY door installation
- Use a template for hinge placement if drilling new holes.
- Add a cabinet‑tip restraint in addition to wall anchoring for extra safety.
- Consider magnetic catches for a clean look.
The implication: installation is straightforward for post‑2014 owners; earlier units require either drilling or a different door solution.
What are the best hacks for BILLY bookcase doors?
Painting and decorating door fronts
- Use adhesive contact paper for a quick colour change.
- Chalkboard paint turns the door into a writable surface.
- Wallpaper panels can be applied for a custom pattern.
A can of chalkboard paint costs under $15 and transforms the entire look, making the BILLY a flexible piece rather than a plain white box.
Using doors to create a hidden cabinet
- Install magnetic catches to keep doors closed without handles.
- Add push‑to‑open mechanisms for a seamless appearance.
- Use solid OXBERG doors or paint them the same colour as the wall for a built‑in effect.
Adding sliding doors
- Sliding door hardware can be retrofitted
- Requires a track rail above and below; doors must be cut to width.
The pattern: most hacks are cosmetic or involve retrofitting hardware. None are endorsed by IKEA, so load limits and safety must be checked.
Should you add doors to your BILLY bookcase?
Benefits of adding doors
- Reduces dust accumulation on shelves.
- Provides a clean, uniform look.
- Hides clutter from view.
Drawbacks and considerations
- Reduces open display space.
- Adds cost: OXBERG doors run ~$60–$100 per pair.
- Installation time varies (1–2 hours for standard setup).
Cost comparison
Three configurations, one pattern: doors always increase the total investment but add functionality.
- BILLY 80 cm + 2 OXBERG glass doors: ~$190
- BILLY 80 cm alone: ~$100
- Custom wooden doors (DIY): $50–$150 in materials + time.
The trade‑off: paying more for doors means less dust and a tidier room, but the bookcase loses its open‑shelf character.
What are the dimensions and options for BILLY bookcase doors?
OXBERG door sizes
- Width: 39.5 cm (for 40 cm units), 79.5 cm (for 80 cm units)
- Height: 202 cm
- Depth: 1.8 cm
Materials and finishes
- Glass doors: tempered glass frame with particleboard back
- Solid doors: particleboard with foil finish
Glass vs solid door comparison
- Glass: shows contents, less privacy, but lighter weight.
- Solid: hides contents, more heat‑resistant, heavier.
The pattern: choose glass for decorative display, solid for clutter hiding. Both offer the same hinge system and installation.
Quotes and expert perspectives
“It was meant to be a simple, functional bookcase for everyone.” – Gillis Lundgren (IKEA designer), as quoted on Wikipedia.
“The door does not fit BILLY bookcases purchased in spring 2014 or earlier.” – IKEA US product page (IKEA US – safety guidance).
The implication: compatibility is the single biggest variable — check your BILLY’s purchase date before buying doors.
Summary
The BILLY bookcase door ecosystem is straightforward for post‑2014 owners: match the OXBERG door width to the shelf bay, anchor the unit to the wall, and adjust the hinges. For older units or custom designs, drilling and third‑party components add complexity but also stylistic freedom. For the average home owner in the US, the clear choice is OXBERG glass doors for an immediate, safe upgrade — for anyone seeking a built‑in look, solid doors painted to match the wall deliver the best result.
Frequently asked questions
Can you use OXBERG doors on older BILLY models?
No — OXBERG doors only fit BILLY bookcases purchased after spring 2014. Older units have a different hinge hole pattern.
How to adjust hinges on OXBERG doors?
Use the two screws on the hinge: turn left‑right screw for horizontal alignment, front‑back screw for vertical alignment.
Are there other door series for BILLY besides OXBERG?
No official alternative exists from IKEA. Some third‑party manufacturers produce compatible doors, but they must be measured and drilled to fit.
How to remove doors from a BILLY bookcase?
Lift the door upward slightly and tilt it outward. The hinge brackets remain on the bookcase; unscrew them if needed (see IKEA manual).
What tools do I need for DIY doors?
Drill, screwdriver, level, tape measure, hinge kit, and optional template for consistent hole placement.
Can I install doors on a 120cm wide BILLY?
Yes — use three OXBERG doors (one per 40‑cm bay) or a custom wide door with appropriate hinges.
