upper limits
Highest allowed values
Upper limits are the maximum values or boundaries that cannot be exceeded.
The term appears in technical contexts—mathematics, statistics, engineering—but also in everyday usage: There's no upper limit on how much you can contribute.
Speed limits, credit limits, and tolerance thresholds all have upper limits.
The phrase often implies a ceiling imposed by rules, capacity, or practical constraints.
