Henri Laaksonen has found clay courts difficult, recording 22–31 across 53 matches (41.5%). 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 (Roland Garros): Henri Laaksonen is 4–4 (50.0%) across 8 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

By format on clay — best-of-five: 6–6 (50.0%); best-of-three: 16–25 (39.0%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 2017 — 3–2 (60.0%) from 5 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
