A simple way to find this out in Windows is to run SQLPlus from your Oracle homes's bin directory and then check Task Manager. If it is a 32-bit version of SQLPlus, you'll see a process on the Processes tab that looks like this:

sqlplus.exe *32

If it is 64-bit, the process will look like this:

sqlplus.exe
