Akira Yoshizawa swan

[subhmohanty]

Hi,
I watched a video on youtube of Sensei Akira Yoshizawa folding the swan. What I couldn't get is the shape and size of paper. Its a triangle, but how to get that triangle shape, say from a A4 paper?

Any help/suggestions would be appreciated.

Regards,
Subh

tried with an equilateral triangle, seems to work fine
