Q. Should I back up before deleting themes?
Definitely, before making any changes, always make a backup of your website.
Q. Will deleting old themes improve site speed?
It can help reduce load time slightly, especially if themes are loading background files or causing conflicts.

Not if you delete only inactive themes. Your active theme must remain untouched. If you unintentionally remove your active theme, WordPress will attempt to use the default theme.

It depends on how often you test new themes. If you’re a developer or designer, do it monthly. For regular users, once every few months is enough.
