This question already has an answer here:

What is the size of the Ethereum blockchain for full and light nodes?

What is the size of the Ethereum blockchain, and where can I look it up?

Furthermore, does the size depend on the particular client, e.g., geth?

How much does the size increase over time? Is the growth rate fixed?

Also, I'm running two nodes on two different machines with

parity --tracing on (70 GB)

in one case and

parity --tracing on --pruning archive (556GB)

in the other. Sizes are listed next to the command line. Not sure if size depends on client, but I would guess not to a big extent.

While the chart above looks sort of like the rate of growth is fixed, I don't think it is (at least not for the archive mode). At the time of the Byzantium fork my archive node was about 330 GB (that's after nearly two and a half years). Since then, it's added 220GB. Clearly not a fixed rate of growth.
