The length of your terminator doesn't matter
Many designers go to great lengths to make sure they do appropriate length-matching, even to the level of including the lengths of their terminators (resistors) in their routing. Although this seems like a way to be ultra-precise, it is actually being less precise. The reason is that the body length of a resistor is very small compared to the change in edge rate and thus real delay caused by the resistor.
