Holger Rune holds a solid hard court record of 108–64 across 172 matches (62.8%). A winning majority across 172 matches shows consistent ability to get results on hard. Claimed 2 titles on hard: Stockholm, Paris Masters.

At Grand Slam level (Australian Open & US Open): Holger Rune is 9–9 (50.0%) across 18 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 hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): Holger Rune is elite here — 40–21 (65.6%) across 61 matches. Sustaining that win rate in the Tour's deepest regular-week draws is a defining quality of the very best on this surface.

6 finals reached on hard — won 2, lost 4 (33% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 16 semifinals. 23 quarterfinals.

vs. Top 10 on hard: 11–14 (44.0%, 25 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall hard court profile.

By format on hard — best-of-five: 9–9 (50.0%); best-of-three: 99–55 (64.3%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on hard.

Peak season: 2022 — 25–11 (69.4%) from 36 matches. That year captures the ceiling of what Holger Rune can do on hard when performing at their best and represents the standard to aim for.
