How Much Quantity of Ganache I need?

This question came to my mind a lot when I just started caking.

I did ask around I get answered like:

"If you make ganache from 2 x 900 ml of cream plus the chocolate,

it should be enough.  If not, just make more."

I appreciated it but not quite satisfying,

so I begin to write down the ganache quantity I used

everytime I ganached the cake.

So based on the above, I would like to share my experienced

to those who need it, hopefully it will be useful,

just remember: every cake decorator has different was of ganaching their cakes.

Below are mine and always enough for me to cover 2 cakes each to achieve 4" height for each cake:

For 6" round: you will need 300 ml of cream.

For 8" round: you will need 600 ml of cream.

For 10" round: you will need 900 ml of cream.

For 12" round: you will need 1,200 ml of cream.

The Cream: use liquid cream, not thickened cream.

For Semi-sweet or Dark Chocolate Ganache:

you will need 1 :2,

means: for 300 ml of cream, you will need 600 grams of chocolate.

For White Chocolate Ganache:

you will need 1 : 3,

means: for 300 ml of cream, you will need 900 grams of chocolate.
