Frederik Fetterlein has a competitive hard court record of 12–13 across 25 matches (48.0%). The record shows a player capable of competing here, though there is clear room to push the win rate higher.

At Grand Slam level (Australian Open & US Open): Frederik Fetterlein is 2–2 (50.0%) across 4 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

By format on hard — best-of-five: 5–3 (62.5%); best-of-three: 7–10 (41.2%). Significantly better in five-set matches — a strong physical profile on hard that tends to tell as matches and tournaments progress.

Best season: 1995 — 3–2 (60.0%) from 5 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
