Kjell Johansson has a competitive clay court record of 76–88 across 164 matches (46.3%). The record shows a player capable of competing here, though there is clear room to push the win rate higher. Kjell Johansson has reached 2 finals without yet claiming a title on clay — one of the finest margins in tennis.

At Grand Slam level (Roland Garros): Kjell Johansson is 7–9 (43.8%) across 16 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

2 finals reached on clay — none converted into a title yet. Reaching 2 finals is a mark of real quality, but the gap between finalist and champion is one of the finest lines in the sport. 5 semifinals. 13 quarterfinals.

vs. Top 10 on clay: 1–15 (6.3%, 16 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: 6–19 (24.0%); best-of-three: 70–69 (50.4%). 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: 1978 — 14–9 (60.9%) from 23 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
