TIL Bitcoin Optech has a handy calculator for sizes of transactions of different types: https://bitcoinops.org/en/tools/calc-size
Is segwit P2WSH? I forget.
P2wsh is one of the segwit types, the other is p2wpkh. Technically, taproot (p2tr) is also segwit, it's segwit v1 not v0
Ok, so p2wpkh is the one I think I care about. 👍
I have a more customizable Bitcoin transaction size calculator here https://jlopp.github.io/bitcoin-transaction-size-calculator/
