Northern pike in North America seldom reach the size of their European counterparts; one of the largest specimens known was a 21 kg (46 lb) specimen from New York.
It was caught in Great Sacandaga Lake on 15 September 1940 by Peter Dubuc.
Reports of far larger pike have been made, but these are either misidentifications of the pike's larger relative, the muskellunge, or simply have not been properly documented and belong in the realm of legend.

As northern pike grow longer, they increase in weight, and the relationship between length and weight is not linear.
The relationship between total length (L, in inches) and total weight (W, in pounds) for nearly all species of fish can be expressed by an equation of the form
Invariably, b is close to 3.0 for all species, and c is a constant that varies among species.
For northern pike, b = 3.096 and c = 0.000180 (c = 7.089 enables one to put length in meters and weight in kilograms).
The relationship described in this section suggests a 20-inch (510 mm) northern pike will weigh about 2 lb (0.91 kg), while a 26-inch (660 mm) northern pike will weigh about 4 lb (1.8 kg).
