I'm not sure about offsetWidth (I never used it). But to get the length in pixels you can use the idealBoundingRect attribute from the edit element. See the 5.5 release notes for an example. Basically you create an invisible edit field with the same font, size and attributes like your link. Then set the value to the text you want to get the width in pixels for. Using idealBoundingRect you can then read the needed width of the text.
