Once your spiders are around 2 inches across, then you can get away with popping them into full size tanks. My tanks are 9"x9"x12", and I find that's more than enough space - enough room for them to avoid crickets if they aren't hungry, but not so big they look lost.
Moving them can be fun.
I teased the spider out slowly using a chopstick, so it's in the open rather than in a burrow.
Then, get a freezer or food bag and lay it open on the floor in front of the spider.
Nudge the spider from behind a couple of times, and it should run into the bag at a mighty rate of knots - you need your wits about you though, incase it legs it in the other direction and escapes up the side of the glass.
As soon as the spider is in the bag, it will try to hide in the corner.
Just pick the bag up, and plop it in the new tank. The tarantula will climb out when it's ready. When it's climbed out, remove the bag.
Other techniques involve using something like an old cricket tub (I always keep mine) and just putting it over the spider, like you'd use a glass to catch a house spider. Slide a piece of stiff card or similar under it and move the whole shebang into the new tank.
Some people do this whole operation in a wet bath - this way if the spider does go nuts and get out, you can trap it using a cricket tub before it gets too far - they struggle to walk up the wet sides of the bath.
