my small rocket chute size

Hey, i want to make a 8 gore chute for a 500g rocket. I calculated a diameter of 108cm (42.5 in), for a descent velocity of 3 m/s (10ft/sec). It will be a semi ellipsoid one. Do you think this chute has a good size? Do you think this chute fit well in a 4cm (1.5 in) diameter rocket? thanks :))
