INCREASING the `:html-scale' scale property in
`org-format-latex-options' will INCREASE the `-D' option by same factor.

I believe the above setting together with a "suitable" value of
#+ATTR_ODT: (:scale xxx) will achieve the required balance.

If you have lots of equations then applying #+ATTR_ODT option to each of
the images is a bit cumbersome. In that case you can tweak
`org-export-odt-pixels-per-inch' (The default value of this variable is
same as `display-pixels-per-inch' variable of Emacs session). HALVING
this variable will DOUBLE the size of all images uniformly.

Note for posterity:
1. ODT expects that the image size be specified in cms or inches. I
   believe image files have no "physical" dimensions associated with
   them but only pixel size. Mapping from pixels to cms or inches is
   again determined by display properties (ie, the same image will
   appear in different physical dimensions on different monitors.)

2. On my Netbook, MS Paint uses a pixels-per-inch of 96.0 while Emacs'
   display-pixels-per-inch reports a value of 72.0

Image sizes are a grey area to me. If there is an expert out there
willing to educate me I am all ears.
