ᐅ Sliding Door Issue with the Ikea Pax Wardrobe

I’ve come across this problem several times while searching online, but in my case, the measurements are slightly different by a few centimeters.

I have the specification that the minimum ceiling height for assembly must be 244 cm (96 inches). Why do so many people say it’s 240 cm (94 inches)? My PAX wardrobe is only 236 cm (93 inches) tall.
In any case, my room’s ceiling height is 242 cm (95 inches). The salesperson said that wouldn’t be a problem, and that the wardrobe should be assembled lying down, the sliding doors installed while lying flat, and then the wardrobe stood up. Well, I bought everything…
At home, I took a closer look and realized that this doesn’t work because the wardrobe won’t fit diagonally in my room when assembled lying down.
So how much clearance is actually needed above when assembling it standing up in order to hang the doors?
It’s frustrating that she told me something so misleading. She also said that if my ceiling is lower than 244 cm (96 inches), requiring assembly lying down, the IKEA assembly service wouldn’t do it. (Otherwise, I would have hired them; I currently have a request posted on MyHammer. I hope we find someone via MyHammer. The wardrobe will be delivered on January 3.)

It is only possible to assemble standing up with a ceiling height of 244 cm (8 ft) or less. Above that (note that a cabinet’s diagonal length—from front bottom to back top—is different from just the vertical height).

Lying down is not possible; either the installer misspoke or confused something. The installers build the cabinet strictly according to the instructions. So, I believe the installers only assemble the sliding doors when the minimum ceiling height is 240 cm (7 ft 10 in), since the instructions only describe this option. Sliding the doors in from the side was not intended. No one knows why, but IKEA must have had a reason. Because the installers are responsible for correct installation, they follow the instructions. Therefore, a minimum ceiling height is required.

So:

Under 238 cm (7 ft 9.5 in): No sliding doors
From 238 cm (7 ft 9.5 in) to 240 cm (7 ft 10 in): Assemble standing and slide doors in from the side
From 240 cm (7 ft 10 in) to 244 cm (8 ft): Assemble standing and hang the doors
Above 244 cm (8 ft): Assemble lying down and hang the doors

Regarding the 238 cm (7 ft 9.5 in) measurement, I ask for corrections from those who have tried this height. If it also works at 236 cm (7 ft 9 in), or only at at least 239 cm (7 ft 10.5 in), I will update these measurements accordingly.

Today, I was very frustrated with the Ikea hotline, so I decided to go there in person spontaneously.
The first woman definitely confused something because she explained it to me completely wrong. But today I spoke to another sales assistant who also told me about sliding the doors sideways.

Is there perhaps an instruction manual for that somewhere?

I also asked him again about the ceiling height, and he said it needs to be 244 cm (8 feet) to follow the instructions properly.

I have another question: When the wardrobe is delivered, is all the material included (for example, screws)?

Thank you very much for your response and your help.

Again:

Under 238 cm (94 inches): No sliding doors
From 238 cm (94 inches) to 240 cm (94.5 inches): Install upright and slide doors in sideways.
From 240 cm (94.5 inches) to 244 cm (96 inches): Install upright and hang doors.
Over 244 cm (96 inches): Install lying down and hang doors.

Yes, all screws are included...

By the way, cabinet sections that are 50cm (20 inches) wide can also be assembled lying down at just under 244cm (8 feet) in length and then stood upright by tilting them over the side panel. Calculating the required ceiling height is not a problem either, since practically everyone knows the Pythagorean theorem.

Thank you all, I have already used the Pythagorean theorem as well, but I have 1 meter (3.3 feet) wide corpora.
