Tennis String Patterns: 16x19 vs 18x20

6 video lessons

What the numbers mean and which pattern suits you.

Quick answer & tips â–¾

A string pattern is the number of main (vertical) strings by the number of cross strings, so 16x19 means 16 mains and 19 crosses. An open pattern like 16x19 or 16x18 has more space between strings, which lets them move and snap back for extra spin, a bit more power and a softer feel.

A dense pattern like 18x20 gives a flatter, lower trajectory with more control, and strings tend to last longer, but it takes a faster swing to create spin. Most club players are best served by 16x19. Players who hit big and break strings often, or who want a more precise feel, try 18x20.

Key tips

  • 16x19: more spin, launch and comfort.
  • 18x20: more control, lower launch, longer string life.
  • Same frame, different pattern can feel like a different racquet.
  • Demo both before you buy if you can.

FAQ

Is 16x19 or 18x20 better for beginners?
16x19 for most. It is more forgiving and makes it easier to get spin and depth.
Does 18x20 give less spin?
With the same swing, usually a little less, because the strings have less room to move. Fast swingers can still generate plenty.
Do strings break faster in an open pattern?
