Radek Stepanek holds a solid clay court record of 101–82 across 183 matches (55.2%). A winning majority across 183 matches shows consistent ability to get results on clay. Radek Stepanek has reached 3 finals without yet claiming a title on clay — one of the finest margins in tennis.

At Grand Slam level (Roland Garros): Radek Stepanek is 14–13 (51.9%) across 27 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): a positive 31–30 (50.8%) across 61 matches — winning above .500 at this level, week in week out, is a genuine sign of quality on clay.

3 finals reached on clay — none converted into a title yet. Reaching 3 finals is a mark of real quality, but the gap between finalist and champion is one of the finest lines in the sport. 8 semifinals. 16 quarterfinals.

vs. Top 10 on clay: 6–22 (21.4%, 28 matches). Top 10 opponents have represented a clear ceiling on clay; addressing that deficit is the single biggest lever for improving the overall record here.

By format on clay — best-of-five: 18–19 (48.6%); best-of-three: 83–63 (56.8%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Best season: 2002 — 8–3 (72.7%) from 11 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
