How can I adjust the box around my equation?

Question

I currently use the \boxed{} command to place boxes around my equations. However, I would like to have more control of the style of the box. Is there a way to do this?

To take a specific example, the figure below shows both the standard \boxed{} out put (a) and the desired mock-up (b), where I have increased the box size and increased the border thickness slightly.

Are you asking for automated features/parameters to increase border width, or are you asking for different line styles/thicknesses etc. around the box? — Steven B. Segletes, Mar 06 '13 at 14:37
My main aim is to increase the box size. Anything else (line thickness, line style, line colour, etc.) would be a bonus. — User 17670, Mar 06 '13 at 14:44
You say increase box size. That might imply scaling the whole object to a larger size (see scalerel package) or your answer might imply keeping the equation the same size and adding border space. — Steven B. Segletes, Mar 06 '13 at 14:52
@Steven: In my opinion, it's quite clear from the image that the OP wants to keep the equation the same size. — Hendrik Vogt, Mar 06 '13 at 14:56
No one suggested the usual TikZ overkilling solution, so it's my turn; you may have a look to \boxed{}, TikZ and colored equation background and to hf-tikz doesn't box around equation (which shows some new option of the hf-tikz package). — Claudio Fiandrino, Mar 06 '13 at 19:49

Someone is going to suggest a tikz box with multicoloured translucent rounded corners, but before they do I'll observe that \boxed is a thin wrapper around \fbox so you can use

\setlength\fboxsep{...}

to set the padding inside the box and

\setlength\fboxrule{...}

to set the line thickness.
