A4 is metric paper size, it's what everyone uses except that backwards country in America. Paper is usually listed by strength in "grams per square meter" (gsm²) which roughly equates to actual thickness, 3rd rate nations use "pounds" (listed as lbs.). There is also a factor of roughness and brightness. Papercraft works best around 75gsm² on smooth bright paper. Spray or brush applied acrylic coatings are most common for dust and humidity protection.
