For me I prefer tabs rendered as spaces and kept down to a tab-size of 2. This is simple to set in Sublime Text.

First off open Sublime, select Preferences / File Settings - User and your personal File Settings preference file will be opened.

Now copy-and-paste this into the file,

"tab_size": 2,
"translate_tabs_to_spaces": true

Bang, from now on all your tabs will be translated as spaces and kept to a length of 2, where appropriate.

Do remember though the “- user” preference files are the best place to put your own configuration settings, not the “global” files, as your’s will be preserved after an upgrade.
