18 inch is the size that pays for itself: big enough to float on its own with helium, small enough that a shop can stock ten designs without dedicating a wall to them. If you are testing a supplier, test them on this size.
Around 9–10 litres of helium, roughly five days of float when filled to 90%, and it reads clearly from three metres. We print this size on dozens of our existing dies, so your artwork does not need a new tool.
