How to write assembly instructions people can follow
Most complaints name something you can fix. We read 75 low-star reviews about assembly instructions. 67% named a specific problem: errors in the manual (20%), no instructions in the box (19%), pictures with too little detail (16%), several booklets that contradict each other (11%), parts that aren't labelled (9%), or parts fitted the wrong way round (7%). 41% said the instructions were unclear or hard to follow. Here's the fix for each, for your next print run.
What buyers complain about, and the fix
| Complaint | Share of the 75 | In their words | The fix |
|---|---|---|---|
| Unclear, hard to follow | 41% (31) | the instructions could be clearer | Give the manual to someone who has never seen the product. Watch where they stop, and fix that page. |
| Errors: wrong, out of date or reversed steps | 20% (15) | No quote | Build the product from the printed manual, page by page, before each print run and whenever a part or supplier changes. |
| No instructions in the box | 19% (14) | My package came with zero instructions on how to set anything up. | Put the manual where it can't be missed, like inside the lid of box 1, and put the same PDF on the product page, findable by model number. |
| Pictures only, or too little detail | 16% (12) | they Include one schematic printed by a 1997 printer | Keep the pictures and add a short caption to each step. Print the hardware at full size so a screw can be held against the page. |
| Several booklets that contradict or overwhelm | 11% (8) | No quote | One booklet per version of the product, or a first page that says which pages to follow for which option. |
| Parts or hardware not labelled | 9% (7) | No quote | Sticker every part with the letter the manual uses, and bag the hardware by step, not by type. |
| Which way round | 7% (5) | No quote | Show which face goes up or out at the step where it matters, with a 'not this way' picture next to the right one. |
| A video that didn't help | 5% (4) | The assembly video is very hard to follow | If you make a video, make it for this model, follow the manual's steps and part letters, and link it from the manual with a QR code. |
What a video fixes, and what it doesn't
- A video helps most where a drawing struggles: which way a part faces, and steps shown only as pictures. Watching a part turn into place answers the question a still drawing leaves open.
- It doesn't fix a manual with errors or a box with no manual. Fix those first.
- When we make a video from your manual, we build every part and step from it in 3D and use its part letters and hardware codes, so the video and the booklet in the box tell the same story.
- Link the video from page 1 of the manual with a QR code, and from the product page.
How we did this
- On 30 October 2026 we pulled the public reviews of 13 online stores that sell flat-pack furniture, kids' beds, gym equipment, grills and outdoor kits. Reviews from 1 of them wouldn't load, so the numbers cover 12: 42,590 reviews, 1,244 of them 1 to 3 stars.
- We read the 108 low-star reviews that mention the instructions. We dropped duplicates and reviews about something else, which left 75. One review can name more than one problem, so the shares add up to more than 100%.
- We found these stores while looking for instruction complaints, so the numbers show what goes wrong when instructions fail, not how often they fail.
- We don't name the stores or the reviewers. Quotes are copied exactly, and we quote reviews from only some of the stores, so some rows have none.
