How do I find the assembly instructions for something I already own?

Question

Accepted Answer

Find the model or article number on a label, the box or your receipt, then search the maker's website for that number with the words "assembly instructions"; most makers publish the PDF on the product's own page, often under documents or downloads.
The number is the key. A product name alone often fits several sizes and versions of the same thing, and each has its own manual. Where to look:
Furniture: a sticker on the back panel, under a shelf or drawer, or inside a side panel near the floor. Flat-pack hardware bags often carry part numbers too.
Appliances: a rating plate inside the door frame, on the back, or behind the kick plate at the bottom.
Electronics and computers: under the base, inside the battery or memory cover, or in the system settings.
Anything bought online: the order confirmation email, and the end label of the box if you still have it.
Then search the maker's own site for the number. Most makers keep the manual on the product page under a heading such as documents, downloads or support; large flat-pack retailers, IKEA among them, list the assembly instructions PDF there. Adding "PDF" or "assembly instructions" to a web search for the number works too. Prefer the maker's file over a copy on another site: copies can be for another size or an older version.
No number anywhere? Measure the piece (width, depth and height) and photograph a distinctive part: the hardware, a bracket or a printed code on a panel. With the brand and the size, the right manual is usually the first or second result.
What BuildMog adds: photograph the product, its label or the box, and BuildMog names it, looks for the maker's own manual first, and builds it in 3D, step by step, in about 2 to 3 minutes. As of 22 October 2026 that is not switched on yet; it opens at launch. Today the six manuals in the library open in 3D for free, with nothing to install.
