YaST normally proposes a reasonable partitioning scheme with sufficient disk space. If you want to implement your own partitioning scheme, consider the following recommendations concerning the requirements for different system types.
Table D-1 Partitioning Recommendations
Depending on the amount of space and how the computer will be used, adjust the distribution of the available disk space. These are some basic guidelines for partitioning:

Depending on the hardware, it might also be useful to create a boot partition (/boot) to hold the boot mechanism and the Linux kernel. This partition should be located at the start of the disk and should be at least 8 MB or 1 cylinder. As a rule of thumb, always create such a partition if it was included in YaST’s original proposal. If you are unsure about this, create a boot partition to be on the safe side.
You should also be aware that some (mostly commercial) programs install their data in /opt. Therefore, you might want to create a separate partition for /opt or make the root partition larger.
