We analyze the limits that quantum mechanics imposes on the accuracy to which (4+n)-dimensional spacetime geometry can be measured. Using physics of computation and the light sheet concept we derive explicit expressions for quantum fluctuations and explore their cumulative effects for various spacetime foam models.
