Help Ideal rope for hanging

[Hangman.]

My main goal is to compress the carotid arteries because I will attempt full suspension hanging and want to lose consciousness as soon as possible. I will use the window grill made of stainless steel as an anchor point.
Which type and thickness of rope would be ideal for this?
Also, should I trust random companies on Amazon for it? If you know any trustworthy companies, please mention them.

I have decided on static nylon rope with 1.5 cm thickness for now because it provides exceptional strength and minimal stretch. But I am quite skeptical about the thickness which will provide great amount of pressure on the neck without that much suffering.

The heavier you are the thicker the rope can be. If the rope is too thin it will cause unneccessary pain. You need not so much pressure to flatten the arteries through your neck and more pressure, a thinner rope causes only additional pain. I, 90 kg pass out reliable with a 20 mm rope. You also have to be sure, that the rope takes your weight.

How do you got the info on which kind of rope fits for X number of kg ?

There is no need to overcomplicate it. You don't need calculations for thickness. Instead, focus on rope strength. Get a synthetic rope that is strong enough with a good safety margin, but not overkill – the way I look at it, that's the formula. You'll find that a Polypropylene (PP), Polyester (PES), or Nylon rope in the 10 to 12 mm range is usually strong enough. You can go even higher, like 14 to 16 mm, which is already way stronger than necessary, but still thin enough to work well. I would say 18 to 20 mm is where thickness might become problematic for extremely light individuals. (But consider that people successfully hang themselves even using things like bedsheets or scarves, so even an overly thick rope won't necessarily be a problem.)

For me it is most important that it is not too painful, that the pressure on the neck is not unnecessary high, just enough to pass out. Normally you first practice a little and if the pain is unbearable you sort this method out. The pressure is proportional to the bodyweight divided by the rope diameter, so if 90/20 is ok for me to pass out reliable, a rope thickness of 13 mm would be adequate if your weight is about 60 kg.
For each rope in a store is the allowed maximum rope force indicated.
