What are the string patterns in tennis? A “string pattern” refers to the number of main (up and down) strings and the number of cross (side to side) strings. The most common patterns around are 18 × 20, 16 x 19, 16 x 20 and 16 x 18. … A dense pattern refers to very small spaces between the strings, while an open pattern has more separation between the strings.
