Does Racquet Headsize Matter?

As the Headsize increases so will POWER! This is because the strings used are longer and create more of a trampoline effect (softer stringbed) upon impact with the ball / shuttlecock with all other things being EQUAL.

ITF Rules:

The racket shall not exceed 73.7 cm (29.0 inches) in overall length, and 31.7 cm (12.5 inches) in overall width. The hitting surface shall not exceed 39.4 cm (15.5 inches) in overall length, when measured parallel to the longitudinal axis of the handle, and 29.2 cm (11.5 inches) in overall width, when measured perpendicular to the longitudinal axis of the handle.

BWF Rules:

The racket shall be a frame not exceeding 680 mm in overall length and 230 mm in overall width. The stringed area shall not exceed 280 mm in overall length and 220 mm in overall width.

The equation used is the basic equation to measure an ellipse:

Area = π x a x b

The results may look insignificant but they do play an important factor on deciding what tension goes onto the racquet or what string bed stiffness a player wants to play with.

Time to measure some racquets and try it out!
