String Pattern16x1918x20
Not Every 16×19 Is an Open Pattern
The spacing of the strings inside the head is a more direct clue than the string count alone.
Player overview
The same notation can produce different launch angles, string movement, and perceived durability when head size and center spacing differ.
Measurement guide
- Read the main-by-cross count together with head size.
- Compare the string spacing at the center of the hitting area in photos or on the actual racquets.
- With the same string, playtest trajectory, snapback, and breakage rate.
Latest measurement
Read a pattern through its actual density and the full frame design, not the string count alone.
