Together with an example to transaction size calculation, I would like to give newbies two websites for Transaction Size Calculator.

https://bitcoinops.org/en/tools/calc-size/
https://jlopp.github.io/bitcoin-transaction-size-calculator/

They can easily choose number of inputs, outputs, and transaction type to have a transaction size.
