Pironkova plays right-handed, and uses a double-handed backhand. She prefers fast surfaces, with grass being her favourite. She has had some of her best results on grass, a Wimbledon semi-final and quarter-final, which earned her the nickname "The Wimbledon Darkhorse". Although she has a powerful first serve that consistently measures up to 180kmph or 110 mph, she has a relatively weaker second serve. Pironkova is noted for her powerful backhand, with the down-the-line backhand being one of her best shots. However, her forehand–albeit reliable, has been variously described as "bizarre" and "clever", owing to the unusual amount of spin and/or slice on the shot. The Daily Telegraph commentator Emily Benammar noted in 2010 that if Pironkova's, "forehand comes up to scratch, she's in with a chance of beating the best".
Overall Pironkova does not rely heavily upon her groundstrokes, but is instead noted for her stroke-play, variety of shots and intelligent use of the court and its geometry. She is also known for her squash-shot forehand and for incorporating flat and slice shots into rallies from her forehand and backhand sides. Pironkova varies the length of her shots and often draws her opponent forward with short balls to set up passing shots. She also makes her opponents more around the court by making use of deep cross-court groundstrokes to keep them off balance. Pironkova admittedly prefers shorter rallies, and looks for winners early in the point which at times leads to unforced errors. She told the freelance tennis writer Matt Trollope that she played mostly on clay courts early in her career and that the aggressive style developed "pretty naturally" during her formative years.
Pironkova's style of play has drawn comparisons with such players as Belgian Justine Henin. Sports columnist Simon Briggs elaborated on the similarity in the styles noting that Pironkova's court craft and tactical nous made her capable of "reflecting the Williams sisters' own power back against them". Pironkova is also credited for her great movement on the tennis court by such commentators as Briggs, who was appreciative of her "nimble" footwork at the 2010 Wimbledon Championships. Pironkova thought of her movement on the grass courts as her among all the surfaces. She also ascribed the optimum ball bounce on the grass as it is, "probably just perfect for [her] timing". Having been praised for her range of shots and strokeplay, Pironkova said that she developed a spontaneous approach towards her shot selection and overall game as she matured.
