Ivo Karlovic holds a solid grass court record of 75–44 across 119 matches (63.0%). A winning majority across 119 matches shows consistent ability to get results on grass. Claimed 3 titles on grass: Nottingham, Newport.

At Grand Slam level (Wimbledon): Ivo Karlovic is 17–15 (53.1%) across 32 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

7 finals reached on grass — won 3, lost 4 (43% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 9 semifinals. 17 quarterfinals.

vs. Top 10 on grass: 6–8 (42.9%, 14 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall grass court profile.

By format on grass — best-of-five: 17–15 (53.1%); best-of-three: 58–29 (66.7%). 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: 2007 — 8–2 (80.0%) from 10 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
