The semblance can also be used as a great party trick for parties when you run out of ice cubes.

For the max size think of what's the biggest size you need. Do you need a cube the size of a house? And you have to think how much dust it would use. Would you ever need something more than 2x2x2 meters?

Maybe several characters get surrounded in a trap and a rocket is flying towards them and the user says something like "guys, get close" someone else "what? wait, are you sure you can do this?" "it's our only choice" "hang oonnn". Explosion. And when the smoke clears all the characters survive inside of a cube. They're cramped, but amazed they survived. "I can't believe this worked" "Me neither". One character even says something like "ok, i'm never making fun of your powers"

You can think of what's the largest thing is you need your power to do-what they can do just in the most special occasions, then how you feel like it should work normally, and how it would start at the smallest level. and then adjust so it feels nice. And listen to people like Phantom, they've seen hundreds of oc semblances and know how this works.
