In general, when finding stoichiometric coefficients for a reaction, you'll always want to make sure that you have the simplest possible ratio (i.e. 2:1 is simpler than 4:2), while also having all whole numbers. That's the rule of thumb that I remember to help myself when balancing chemical equations!
