The lighter beige cricket about 6 inches, the banded cricket, about 16 inches.
I would suggest you use the search feature (top right) and you will find several DIY larger cricket/worm containers that allow the bugs to climb up the back inside part of the container, which has screen attached.
If you want to use a smaller cup, the trick is to gently shake the crickets into the feeding cup, when not disturbed they don't jump, or get them in the cup inside the cricket bin you have so you don't loose so many jumpers.
