how to figure out the size of the bytecode from compiler output?

Question

I'm trying to figure out how to calculate the size of the bytecode given the string, given that there is a hard limit for contract size of 24kb.

ie. for USDT Token: https://etherscan.io/token/0xdac17f958d2ee523a2206206994597c13d831ec7#code

80518201919060200180518201919060200180519060200190919050
50336000806101000a81548173ffffffffffffffffffffffffffffff

Is it literally byte[] all = new byte[s.length() / 2] - number of characters in the string divided by 2? or it is something more complicated?

no. I'm asking about the actual string of the bytecode already deployed. — zcaudate, Sep 28 '22 at 13:18
More details about the limit https://ethereum.stackexchange.com/a/47556/. And you are correct the contract will be deployed as raw bytes, so the deployed size will be hexadecimal lengths / 2. Also be aware that the compiler produces two bytecodes, the runtime and the deployment = runtime + constructor. — Ismael, Oct 05 '22 at 21:34

You can take a look at this resource on how to figure out the size of the bytecode from compiler output.

I'm looking at a simpler solution if the hex string is already available. – zcaudate Sep 28 '22 at 13:20
