The effect of measurement-probe geometry on the weak-localization magnetoresistance of short silver wires is investigated. The wires have lenghts comparable to the electron phase coherence length l, which is a few microns at 1 K. The influence of different probe geometries is seen directly in the magnitude and shape of the low-field magnetoresistance of these wires. We have extended the theory of weak localization to include the effects of the measurement geometry, and find good quantitative agreement with experiment.
