upper limit
Highest permitted amount
An upper limit is the maximum value something can reach or is allowed to reach.
It sets a ceiling on quantity, extent, or degree: The upper limit for carry-on luggage is twenty pounds.
In mathematics, an upper limit bounds a set or sequence from above.
The phrase often appears in technical, financial, or regulatory contexts where precise boundaries matter.
