Indentation: Tabs vs Spaces

Was wondering why the decision to choose 2-space indentation over a single 4-space tab?

At least for me and the dev team I work with, we’re all working with tab indentation. The reasoning is summed up well by the answer with 250 votes here:

I’d like to know if there’s a rationale behind the 2-space indentation and if there’s an easy way to convert all files to single tab? Also, does anyone else agree/disagree, what’s the community’s general view?

Personal preference mostly. The only change I could see Roots potentially making would be from 2 spaces to 4 to match up the PSR standards.

Most IDEs have methods of converting spaces to tabs and vice versa.
