Singapore's standard paper size for printouts?

Good afternoon fellow Typophiles,
I'm slated to design a multi-page PDF for our new venture in Singapore. This is going to be printed by various individuals so I need to know what the standard paper-size is. I'd image it is A4 but I'd like to confirm. Does anyone have some insight?

Chinese Font Foundries

I've come to draw upon your collective knowledge for some insight into quality Chinese foundries. I'm looking specifically for simplified Chinese fonts, and I would be doubly satisfied to find people who design fonts that have both traditional and simplified character sets.

I'm not so much interested in individual fonts as the designers themselves, because I'm interested in the development and evolution of what's been brought out.
