Each type of fish has a minimum and maximum size. When a fish is hooked, it is given an initial size based on these values and the size factor, equal to '''<samp>minFishSize + (maxFishSize - minFishSize) * fishSize + 1</samp>''', rounded down, in inches.<ref name="fishSizeRange"/> Every 0.8 seconds that the fish is not being reeled in, it shrinks by 1", to a minimum of <samp>minFishSize</samp>. Additionally, if the catch was imperfect, and the final size is equal to <samp>maxFishSize</samp> exactly, the fish size is reduced by 1".<ref name="fishShrinking"/> A consequence of this procedure is that the maximum possible fish size observed in game is typically 1 higher than the value specified in the data, which can be obtained with perfect or near-perfect catch (less than 0.8 seconds not reeling in the fish). In addition, some fish have the same <samp>minFishSize</samp> and <samp>maxFishSize</samp> in the data, such as the [[Fish#Legendary_Fish|Legendary Fish]] and non-Ghostfish Mines fish; due to the adjustment for non-perfect catches, the minimum possible size for these fish is 1 lower than the value specified in the data.

Some fish, such as the [[Desert#Fish|Desert fish]] or [[Goby]], cannot be caught at their maximum theoretical size, as they are limited by the size of their ponds which prevent a high enough Fishing Zone for maximum size factor.

Base fish quality is directly determined by the size factor, rather than final size: a value below 0.33 corresponds to normal quality, a value between 0.33 and 0.66 corresponds to silver quality, and a value of 0.66 or higher corresponds to gold quality. This quality can be improved by one grade for each [[Quality Bobber]] equipped. It can also be improved by one grade with a perfect catch as long as the fish was at least silver quality initially. These boosts stack, with the Quality Bobber boost considered before the Perfect Catch boost. Since the maximum base fish quality is gold, the only way to get an iridium quality fish is by either getting a perfect catch or using the Quality Bobber.<ref name="fishQuality" />
