Anyone knows how much sugarpaste I need for a 20 inch cake?

Thanks!

This chart goes up to 18"

140oz in kg is 3.96kg, so for a 20" I would estimate at between 4.5 and 5kg.

Good luck covering that beast!!

Is sugar paste the same as fondant? If so, according to a chart I have you would need 6 1/2 pounds of it to cover a 20" round cake. You will need more for a square cake.

Great, thanks a lot! (Yes sugarpaste is the same as fondant). That one is a dummy but it'll be interesting covering that
