No; the only things that give SVG images an intrinsic ratio are:
 * the viewBox attribute on the svg element
 * the height and width attributes on the svg element (but not if
   they're percentages)

This is described in
http://www.w3.org/TR/SVG11/coords.html#IntrinsicSizing .

Via the viewBox attribute.
