ᐅ How can I combine Ikea Besta units in an L-shape to create more storage space?

Hello everyone,

I am planning to expand my apartment’s storage space using Ikea Besta systems, arranged as an L-shape along two adjoining walls. Since I want to make the best use of the available space, I am especially interested in how to combine the individual modules to ensure both storage capacity and flexibility in organizing the interior.

I am particularly concerned about: How do I find the right balance between closed and open units? What dimensions and depths make sense if I want to accommodate large binders or bigger decorative items? And how can I securely fasten everything, especially in the corner area, to ensure stability?

Does anyone have experience with an L-shaped setup using Besta modules and advice on selecting widths, heights, or connecting the units? I would appreciate any recommendations, even small details that pay off later. Thanks in advance!

For stability in the corner area, I can say right away that it is important to screw the components together and attach them to the wall. This prevents the shelf from wobbling or coming loose under load.

Regarding the combination, I recommend mixing different modules with doors and open compartments, as this allows you to separate functional items from decorative elements effectively. The standard depth of 40 cm (16 inches) works well for folders; if large books or electronic devices are planned, a depth of 60 cm (24 inches) can also make sense.

I would add that for an L-shaped combination, it is important to pay close attention to the wall dimensions. The standard width of 60 cm (24 inches) often works best for large compartments, but this can cause issues if the wall measurements do not fit into 60 cm (24 inches) increments plus clearance.

Therefore, plan carefully in advance with a tape measure, and take panels or baseboards into account to position the Besta system as flush as possible against the wall.

Additionally, the interior layout becomes more flexible if you use some shelves instead of doors. This makes it easier to adjust the configuration.

Hello Jimmi,

I’m glad to see you’re already considering the Besta system in an L-shape – it definitely requires some planning to achieve the best results.

First of all, you should measure your wall dimensions precisely and keep in mind that the Besta system is generally available in widths of 20, 40, and 60cm (8, 16, and 24 inches). For an L-shaped combination, a mix of approximately 60cm (24 inches) wide modules (for larger items like binders or media devices) and narrower 40cm (16 inches) modules at the connecting points is often recommended to accommodate any space restrictions.

An important aspect is the depth: the standard 40cm (16 inches) depth is sufficient for binders, but if you want to store a lot of electronics or tapes, 60cm (24 inches) depth might be more appropriate. However, this will make the unit bulkier, so also consider visually how much space you can allocate for it.

The corner connector or a suitable corner panel is essential to visually close the L-shape and avoid gaps at the joints. Since the Besta system is modular, the elements can be connected using screws and fittings.

Also, consider wall mounting: use two to three brackets per frame section to ensure stability, especially in the corner, where the Besta shelving can otherwise tip over.

Regarding the layout: think about whether you want more storage behind doors or to display some items openly. Open compartments are great for frequently used items or decorative objects.

If you want to stay very flexible, it can also be useful to install shelves that can be adjusted in height. This allows you to organize your space perfectly according to binder sizes or other items.

If you’d like, you can share some details about the planned room situation? That would help provide even more targeted advice.

Thanks already for the previous answers; they have been very helpful.

About the room: I have two walls measuring approximately 2.70 m (8 ft 10 in) on the right and 2.50 m (8 ft 2 in) on the left. The ceiling height is 2.45 m (8 ft), but I don’t want tall structures because the balcony door passes on the right side, so I want to keep some clearance. There is also a window opposite, so the storage shouldn’t look too bulky.

It will be used for binders (up to 39 cm (15 inches) wide), books, and some decorative items. A depth of 40 cm (16 inches) sounds good, but with the L-shaped layout, can I also choose a narrower width, for example 40 cm (16 inches) units, so the corner doesn’t feel too cluttered?

And in the corner itself—how can I combine this effectively to keep the space accessible but still use the storage there?

Looking forward to your opinions.

If you want the room to feel airy and not overcrowded, I suggest limiting the height of the Besta units to a maximum of 120 cm (47 inches). This still provides generous storage space but doesn’t feel overpowering.

Yes, 40-cm (16-inch) widths work very well for the corner, especially since they give you more flexibility in the layout and make the corner connection easier.

With Besta, it’s possible to screw different modules together to create custom corner solutions. There are also suitable corner connectors available to ensure stability.

In the corner, you should avoid installing back panels to allow access from both sides — this makes it easier to use and creates a more open feeling.
