Bitcoin Blockchain Size was 470.93 GB for Apr 06 2023.
But it must be considered that Bitcoin Core can run in pruned mode, still verifying blocks, but discarding them, needing far less disk space and hence less investment in hardware.
That said I do not really know how much space this would require.
In case someone wants to build bitcoin nodes as beginner! Do you see bitcoin core as a good software to support the running of the node?
If you are a beginner, you should start with electrum. Move some coins first, buy in an exchange, sell, move to your wallet, etc.
Then when you understand what is going on, invest in your hardware to run a full bitcoin node.

7 gigabytes of free disk space, accessible at a minimum read/write speed of 100 MB/s.
2 gigabytes of memory (RAM)
A broadband Internet connection with upload speeds of at least 400 kilobits (50 kilobytes) per second
An unmetered connection, a connection with high upload limits, or a connection you regularly monitor to ensure it doesn’t exceed its upload limits. It’s common for full nodes on high-speed connections to use 200 gigabytes upload or more a month. Download usage is around 20 gigabytes a month, plus around an additional 340 gigabytes the first time you start your node.
You need at least 385 gb free just to begin with, as the blockchain grows daily
