Does anyone know how many sheets of the standard size, 3 3/8x 3 3/8 (85mm x 85mm), edible gold leaf to cover a 14" round tier that is 6" tall?

AIf you figure your surface area you'll know.

AIf math is not your friend, and no one comes on to answer your question for you, Assuming you want a solid coverage Take 3x3 post it notes and start sticking them on your cake pans. The 3/8" can be your fudge factor.

sheets of the standard size, 3 3/8x 3 3/8 (85mm x 85mm), edible gold leaf = 11.42 square inches each

to cover a

14" round tier that is 6" tall

The circumferenc is around the outside. for 14" diameter and 6" high, that is 263 square inches.so 23.03 sheets for the outside.

the top area is 154 square inches, so 13.48 sheets.

So, 36.51 sheets with ZERO WASTE. It depends how neat you can keep it, how well you apply it, how much you overlap, etc. I would assume 50 sheets would be a reasonable estimate. 

i agree that 50 sheets is reasonable but i would buy an extra pack anyhow because of the learning curve -- if i worked with it regularly i'd cut it that close to 14 extra sheets but just to humor my psychosis -- to know i have it if i need it -- i'd definitely pop the extra fifty-five bucks for a second one --

and the cheap stuff isn't gold -- it's brass or copper or something -- 

oh but she might not need to cover the whole top -- maybe just one pack would do --

i love math people -- thanks j6ou

idk i'm getting nervous -- if it was a square cake that needed 36 pages -- but a round cake -- no i'd definitely get two packs -- just to be safe --

This stuff is hard to work with.  One little breeze and $1 worth floats across the room. . . and another . . . Just be sure to charge the customer for the extra pack you'll likely purchase.
