Leo, A belated thanks for the response. Your link roughly agrees with an application note I found from Micrel. Micrel's application note has a chart showing Thermal Resistance vs. Pad Area. I'm not sure how they came up with it, but it feels correct enough to help keep me out of trouble.

Hi, I'd like to use a large, unmasked, plated, copper pour, on a single layer, to perform as a heat sink for a D-Pak regulator. I need to quantify the thermal resistance of the copper pour to ambient. I know it's based on copper thickness and copper area. I'm uncertain how to boil down to
