How do you make a billboard GUI keep it's size?

When you create a billboard GUI it stays the same size on your screen no matter where you are at. I however would like it to always be the about the same size as the brick it is in.

Is this possible? I've tried changing it's size, it's offset, the size and offset of the frame it's in, and even the size and offset of the billboardGUI object itself. But to no avail, it always keeps it's size as always relative rather than absolute. Any ideas?

I know this isn't much of a scripting question, but google was no help.

"If the Offset of the Size is set then the BillboardGui will maintain the same size regardless of distance to the player."

right there under BillboardGui.

So set the Offset Size to something and experiment.

Set the size of the BillboardGui to negative in the scale sections and 0 in the offsets. this makes the gui get smaller as you move further away, so it will appear to stay the same size the same way an object does
