Dust threshold for Testnet

I want to find a dust threshold following this answer: https://bitcoin.stackexchange.com/a/86069/134293

Actually I have a list of transactions coming from listsinceblock in which there are Testnet pubkey hash addresses (like mzzg8fvHXydKs8j9D2a8t7KpSXpGgAnk4n) of 34 bits, and Testnet script hash addresses (like 2N1SP7r92ZZJvYKG2oNtzPwYnzw62up7mTo) of 35 bits -> https://en.bitcoin.it/wiki/List_of_address_prefixes

How can I find the dust threshold for both? Maybe I need just to know how much I have in input in order to apply the formula: ([input bytes]+[34 or 35])*3
