Default size about svg

[mrpiggi]

Maybe there's been a misunderstanding with you. Inkscape usually creates vector graphics in PDF format, which can be scaled as desired. Specifying the parameters width/height/scale allows scaling the graphic to the desired size within the document. These parameters are passed internally to the \includegraphics command from package graphicx, which is used to include the exported PDF file.

The option inkscapedpi is only meaningfull, if either the export format is PNG or the SVG file contains filtered objects, which should be rasterized.
