Neither of them necessarily directly work with the area used to paint the fontstring. Rather, they're used to compute what dimensions are needed in one direction, given the size in the other direction. | Neither of them necessarily directly work with the area used to paint the fontstring.

Let's assume we have a frame that is 100x100, and that we anchor our fontstring to the topleft corner only, and tell it to display a sizeable chunk of text in a 10 point font, that is ~250 pixels long if nonwrapped (i.e. [[API FontString GetStringWidth|GetStringWidth()]] would return 250). | Let's assume we have a frame that is 100x100, and that we anchor our fontstring to the topleft corner only, and tell it to display a sizeable chunk of text in a 10 point font, that is ~250 pixels long if nonwrapped (i.e. [[API FontString GetStringWidth|GetStringWidth()]] would return 250). | ||

When you control the dimensions by anchoring more than one point, the drawn text will obey your points. But GetWidth() and GetHeight() continue to operate in their own little world. | When you control the dimensions by anchoring more than one point, the drawn text will obey your points.
