"It's up to you"

[satchrocks]

I would normally say (translating from English):

"Está para tu decidir"

Is there a better way to express this?

[Tomisimo]

It's up to you.
Tú decides.
Te toca decidir.
Es tu decisión.

[María José]

I would normally use the first of David's translations: Tú decides. Or also: Lo que tu quieras.

[chileno]

¿Está en ti (decidir)?

[ROBINDESBOIS]

depende de tí
es asunto tuyo

[AngelicaDeAlquezar]

Maybe also:

Es cosa tuya.
Allá tú.
Como quieras.
