What is the problem of having too big a parachute?

A parachute that is too large can create several issues, primarily excessive drag, which can lead to a slower descent and increased difficulty in controlling the landing. This can make it harder to steer and stabilize during descent, potentially resulting in unsafe landings. Additionally, a larger parachute may be more cumbersome to pack and deploy, complicating the jump process. Overall, it can compromise both safety and efficiency in parachuting.
