nope. the big one is... as big as the normal size of a paperboard.. the small one, is half the size of the big one. both still bigger than A4..
U can go to carrefour and find it at the stationary aisle. Sure got.

And yes, i tape them together. But not using the normal clear tape thats made for the paper la.
I use the heavy duty tape. the one that comes with so many color. Also dunno whats the proper name for it lol

btw if u can find a bigger coroplast board then its better. Those i think can get from hardware stores / advertisement shops. so u dont have to cut it to pieces and then put them back together. u can instead do something like this :
