choosing the size of the swap:
https://wiki.ubuntuusers.de/Swap/
The appropriate memory size depends on several factors and cannot be specified in general. Depending on system usage, around 1 GB of swap space or 1 GB + RAM capacity for suspend-to-disk is sufficient. If the swap space (and RAM) fills up, the system may crash and all data not synchronized with the hard disk is lost, which is why a generously designed swap area can make sense
what about a Swap:

well now i want to set up a swap
that said i want to narrow down the partition abotu 8 gb and then create a swap

Swap partition```
A swap partition can be created with most GNU/Linux partitioning tools. Swap partitions are designated as type 82 on MBR and 0657FD6D-A4AB-43C4-84E5-0933C84B4F4F on GPT.
To set up a partition as Linux swap area, the mkswap(8) command is used. For example:
```# mkswap /dev/sdxy```
Warning: All data on the specified partition will be lost.
To enable the device for paging:
```# swapon /dev/sdxy```
To enable this swap partition on boot, add an entry to /etc/fstab:
UUID=device_UUID none swap defaults 0 0
where the device_UUID is the UUID of the swap space.
See fstab for the file syntax.
Note: The fstab-entry is optional if the swap partition is located on a device using GPT. See #Activation by systemd
