ᐅ Are there assembly instructions available for IKEA HEMNES shelves with custom dimensions?

Hello everyone, I have a somewhat specific question: Are there assembly instructions or construction plans for Ikea Hemnes shelves that don’t follow the standard dimensions, meaning custom or individual measurements? Specifically, I’m looking for guidance to assemble a Hemnes shelf with different width and height without having to buy completely new shelf components. I’m interested in how existing assembly instructions or parts can be modified to achieve, for example, a non-standard shelf depth or extra-wide measurements. I’m familiar with the original Hemnes kits, but they only cover a few standard sizes. Has anyone had experience with custom adjustments, modifications, or are there any official or unofficial instructions for non-standard sizes? Thanks in advance!

I am not aware of any official assembly instructions for HEMNES shelves with custom dimensions. Usually, the best approach is to use the standard size as a base and make your own modifications. If you want to enlarge the shelf, you will typically need to buy additional materials yourself and use the instructions only as a rough guideline.

Super interesting question! 🙂 I think it’s great when people customize Ikea furniture. Official assembly instructions for custom sizes are probably rare, but don’t let that discourage you! Often, with some initiative and creative thinking, you can find really great solutions. Good luck with your tinkering, I’m sure you’ll manage it!

The question of assembly instructions for Ikea HEMNES shelves in custom sizes is technically quite complex. Ikea designs its products modularly, but the assembly instructions are tailored exactly to the standard dimensions. If you want to create custom sizes, you should consider the following: - The wooden parts have specific grooves and drill holes that are prefabricated in identical multiples - For extending or widening the shelf, custom wooden parts need to be made or cutting services commissioned - Assembly is done using precise wooden connectors, whose positioning must be followed exactly - Changes to the shelf depth are particularly tricky because the back panels and side panels must fit correctly - Safety aspects (e.g., load capacity and stability) must not be underestimated In my experience, you can generally follow the instructions using the available materials and standard connectors, but for custom sizes, I recommend drawing up an exact plan and possibly having custom cuts made. How large are your planned deviations from the standard? For example, is there a maximum depth you do not want to exceed?

Thank you for the input, you are right about the technical depth. The plan is for a width of 120 cm (47 inches) instead of the usual 80 cm (31 inches), so about 50% wider. The height should be around 220 cm (87 inches), which is roughly 20 cm (8 inches) more than the highest standard. However, I would like to keep the depth at the 30 cm (12 inches) of the standard HEMNES shelves to avoid space issues. I am specifically asking about connection methods—does anyone have experience with alternative drilling patterns or fasteners to ensure stability when increasing the width? Are there components available at hardware stores that might connect the shelves more securely than the original dowels?

A width of 120 cm (47 inches) and a height of 220 cm (87 inches) is definitely feasible, but you need to consider the structural stability. For the connections, you can use sturdy furniture brackets or metal connectors from a hardware store. The original dowels are often not sufficient, especially when widening. Pay attention to the quality of the fittings and use concealed screw connectors in load-bearing areas. It can also help to add extra back panels or a central brace to prevent bending.
