What size grow tent for 4 plants?

I'm looking to grow 4 plants in a grow tent. What should the dimensions be so I can get a pretty good yield?

Thanks!

i would use a 4ft by 4ft by 7ft and you will have excellent yields. thats what im using right now get it off ebay super cheap.

Nice! Do you happen to have any pics of your set up? This will be my first attempt so I would like to see what it will look like when done. If not, no worries!
