Page In's vs Page Out's

[heisenberg123]

In my Activity Monitor under memory im using some page outs so that means i'm running out of memory at some point but its usually small like 1% of Page in's, is this enough reason to get more RAM or is it happening so little that i run out of memory that i wouldn't notice the upgrade?

The computer would benefit from more RAM, but if the difference is that small, you may not be able to notice it.

The only thing to look for is Page Outs. It doesn't matter what the ratio is between Page Ins and Page Outs, as they're unrelated. You will always have Page Ins. You won't always have Page Outs. Both are cumulative since your last restart. To determine the need for more RAM, restart your computer to reset the count to zero, then monitor Page Outs under your normal workload. If they're significant (say 1GB or more), then you would likely benefit from more RAM.
