Which board do I need? Answer 3 questions to find the right type

Size tip: the 2nd photo on each board shows it to scale next to an Arduino Uno (6.9 x 5.3 cm). Double sided boards have plated holes, so joints are stronger and pads lift less often. Etching copper clad needs ferric chloride, listed in the copper clad section.
About Zero PCB (Brown Phenolic, Dotted)
Brown phenolic zero PCB, also called dotted veroboard or general purpose PCB: single sided, 2.54 mm hole pitch, a copper pad around every hole. The cheapest way to make a circuit permanent. Sizes from 4.5x3 cm to 18x30 cm.
