Her groundstrokes are hit flat, with little topspin, allowing her shots to penetrate consistently deep into the court despite Mertens' comparatively slight build.

Mertens' superlative fitness, stamina, speed, footwork, and court coverage allow her to excel at counterpunching, and extend points until she creates the opportunity to hit low-risk winners; as such, she is one of the most effective players on the WTA Tour at turning defence into offence, due to her excellent point construction.

Mertens possesses extreme mental toughness, and has been noted for her consistency and determination on court, making her a formidable opponent.
