Paul Kilderry has found hard courts difficult, recording 4–14 across 18 matches (22.2%). 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): Paul Kilderry has yet to record a win on hard at this stage — 0–4 across 4 Grand Slam matches. Breaking through here would mark a significant step forward on this surface.

ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): Paul Kilderry is elite here — 3–1 (75.0%) across 4 matches. Sustaining that win rate in the Tour's deepest regular-week draws is a defining quality of the very best on this surface.

By format on hard — best-of-five: 0–4 (0.0%); best-of-three: 4–10 (28.6%). 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: 1995 — 3–4 (42.9%) from 7 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
