How Big Is A Normal Tennis Racket?

While the rules of tennis allow rackets to measure up to 32 inches in length, most tennis rackets measure from 27 to 28 inches.

Typically, tennis racket heads range in size from 85 to 135 square inches. In general, tennis rackets with larger heads provide more power while tennis rackets with smaller heads provide more control.

Tennis racket grips typically range from 4 inches to 4 7/8 inches in circumference.

So to answer a vague question, tennis rackets vary in all kinds of sizes depending on what you are looking for.
