I counted bitcoin address length, it is 34.

Is this all the same always?

And how about other coin's case?

If same coin, address's length is always same?

NOPE. It's 26-35.

See the official bitcoin wiki - Address (https://en.bitcoin.it/wiki/Address).

You maybe counted correct.




No, the length from 'legacy' addresses (starting with 1.. or 3..) varys from 27 to 34 characters.
The length of new bech32 format addresses (starting with bc1..) is at ~ 42 chars.




This depends on the coin. Usually they are different.
Depends on what is defined within the protocol..




See above.

No, they can be as short as 26 characters eg to as long as 34 for P2PKH addresses (addresses that start with '1')
P2SH (testnet) addresses can have up to 35 characters IIRC.
Bech32 segwit addresses can be as low as ~14 characters long eg to as long as 74 characters.
It depends on the encoding being used by the coin to generate addresses.

No, they have the same RANGE but they're not always the same length.
The encoding provides the range of values that generates a valid address.

In some cases however, the address lengths are always the same because of the way addresses are derived.
For example Ethereum addresses are always 40 characters long (plus the 0x prefix to give 42 chars) because it's the last 20 bytes of the SHA3 hash of the  public key controlling the address.

As I searched on Google, I see the xynerise has given seems perfect answer bro. As I we can see the 32 to 35 characters has there in every bitcoin address but not sure about legacy address and etc mate.
If there is address shrinking option we do for websites link in future. Then we can see bitcoin transaction more anonymous mate. LOL. ;) ;)

No, they're not always the same length  ;D
