I'm trying to understand the physical sizing of SMD Resistor Arrays. I thought the usual SMD sizing codes like 1206 would be used for these components too, but I'm finding that's not the case. A 1206 Resistor network/array is larger than a 1206 resistor. I grabbed a random DataSheet from Digikey to see if it would help me - but I'm just even more confused now:

I've never seen these codes before. Are this not standardized so size specification differs between vendors? I have a resistor arrays that were marked 1206 but as I stated are bigger than 1206. It almost looks like the 1206 marking is as if you would place X number of 1206 resistors side by side to get the array size?
If there's somewhere I can go to learn about the sizing of these components I would like to know. I thought I had what I needed using the usual SMD codes for single caps, resistors, inductors ... alas, I'm wrong.
