Karel Novacek has found grass courts difficult, recording 10–14 across 24 matches (41.7%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

At Grand Slam level (Wimbledon): Karel Novacek is 7–10 (41.2%) across 17 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

vs. Top 10 on grass: 0–5 (0.0%, 5 matches). Top 10 opponents have represented a clear ceiling on grass; addressing that deficit is the single biggest lever for improving the overall record here.

By format on grass — best-of-five: 7–12 (36.8%); best-of-three: 3–2 (60.0%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on grass.

Best season: 1994 — 3–2 (60.0%) from 5 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
