Such an option does not exist in the Kobo.
One of the spots on the Kobo's font-size slider in the GUI has to be the default position. You may not be able to snap to it automatically, but that in no way means that you can't get back there.

At any rate, you seem to be leaving some factors out of your calculations: the semantic size of the text, soft vs. hard pixels, and a device-specified hard minimum size.

Semantic size: Okay, so the paragraph text is supposed to be 15px tall. Is that "small" or "medium" - or another point on that spectrum? How is that determined? Does the document have "smaller" relative text that must remain legible?

Soft vs. hard: As far as the web is concerned, all iPads have the same screen resolution, 1024x768. That's because that's what they report; it's their "soft" resolution. However, some iPads (3 and 4) actually have four times that many dots on their screens, 2048x1536.

Hard minimum: Once you get below a certain size, text becomes illegible. That's usually not the desired outcome, so some platforms impose a minimum size for text. (I am given to understand that on some Apple devices, it's impossible to go below six points.) If you were to specify a 10pt standard font size and then include some fine print that's supposed to be 50% of standard, that hard minimum could cause the fine print to lock at 6pt and possibly recalibrate the document norm up to 12pt to preserve the desired proportions. The minimum size could even depend on the particular font(s) being used.

Some or all of those factors could be coming into play here.
