[Bug 10091] As far as I can tell, nothing specifies what the intrinsic width/height/ratio for iframes should be. You'd assume it's the height/width/ratio of the document, but of course that's wrong unless the iframe is seamless.

"   Otherwise, if 'width' has a computed value of 'auto', but none of the
   conditions above are met, then the used value of 'width' becomes 300px.
   If 300px is too wide to fit the device, UAs should use the width of the
   largest rectangle that has a 2:1 ratio and fits the device instead.

"   Otherwise, if 'height' has a computed value of 'auto', but none of the
   conditions above are met, then the used value of 'height' must be set
   to the height of the largest rectangle that has a 2:1 ratio, has a
   height not greater than 150px, and has a width not greater than the
   device width.
"

So 300px by 150px (or smaller if that doesn't fit).
