Patent ID: 8560406

Claim:
A computing system, comprising one or more computing nodes that implement: an information gatherer that during operation: identifies one or more items that are handled in a particular dimensionally-constrained environment in a materials handling facility; and determines one or more dimensions of said particular dimensionally-constrained environment; an item dimension estimator that during operation automatically estimates one or more dimensions of a given one of said one or more items handled in said particular dimensionally-constrained environment dependent on said one or more determined dimensions of said particular dimensionally-constrained environment; a memory that stores said one or more estimated dimensions of said given item; and an item dimension updater that during operation updates at least one of said one or more estimated dimensions of said given item in response to determining that a second dimensionally-constrained environment in which an instance of said given item is handled is smaller than the particular dimensionally-constrained environment, wherein updating the at least one of said one or more estimated dimensions is dependent on one or more dimensions of said second dimensionally-constrained environment.
