というより
...is more of a... than a..., Rather than saying that...
僕は暇だというより、なにをすればいいか分からないだけだ。
Rather than having nothing to do, I just don't know what I should be doing.
Explanation
「というより」 means 'rather than saying..., it is more like...'. You bring up one way of putting it, feel it is not accurate enough, and replace it with a description you think fits better. It often pairs with 「むしろ」: 「今日は涼しいというより、むしろ寒いくらいだ」 (Today is not so much cool as rather cold). It follows the plain form or a noun.
Mixed up with
When you see 「というより」, look for 「むしろ」 among the choices. When you see 「むしろ」, 「というより」 is often before it. This pairing is very stable in past exam questions.
In daily talk it is a soft way to correct someone's slightly exaggerated wording, and it sounds objective and modest.
