Maximilian Marterer has found hard courts difficult, recording 19–37 across 56 matches (33.9%). 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 (Australian Open & US Open): Maximilian Marterer has struggled at Grand Slam level on hard: 3–9 (25.0%) in 12 matches. The best-of-five format and elite fields make this the toughest benchmark on this surface.

ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): Maximilian Marterer is 4–7 (36.4%) across 11 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole hard swing.

By format on hard — best-of-five: 3–9 (25.0%); best-of-three: 16–28 (36.4%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on hard.

Best season: 2023 — 5–4 (55.6%) from 9 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
