What column type/length should I use for storing a Bcrypt hashed password in a Database?

...) consisting of: 22 characters of salt (effectively only 128 bits of the 132 decoded bits) 31 characters of encrypted output (effectively only 184 bits of the 186 decoded bits) Thus the total length is 59 or 60 bytes respectively. As you use the 2a format, you’ll need 60 bytes. And thus for My...

... will need to consider word size (8 bytes in a 64-bit system, 4 bytes in a 32-bit system) when allocating space for n pointers. The size of a pointer is the same of your word size. So while you may wish to allocate space for n pointers, you are actually going to need n times 8 or 4 (for 64-bit or ...
