Fondant Coverage Calculator for Square and Round Cakes

The no. 1 question I get asked by students working with fondant is “How much fondant do I need?”. There is nothing quite as frustrating as running out of fondant when you’re trying to complete a cake late into the night when the shops are closed.

If you’ve found yourself in the frustrating situation of having too much or too little fondant to work with, this Fondant Coverage Guide is just the thing you’ll want to Download and keep on hand.

The fondant coverage chart below can be used as a guide to determine the estimated amount of how much fondant (or sugar paste) is required to cover your cake based on the diameter, height and shape of your cake. I want to emphasise that this is chart is a guideline and not a fixed rule.

Important to note, the exact amount of fondant required will depend on how thick or thin your fondant is rolled to. I would recommend rolling your fondant to the optimal thickness of 3mm-5mm as that provides the best coverage whilst not overwhelming your guests with too much icing to consume.

If you’re interested to learn how I achieve a flawless smooth finish with razor sharp edges on both round & square fondant cakes, check out the Foundations Masterclass Online Course that my students’ have been raving about. I show you my 2 highly effective methods to achieving sharp fondant edges that virtually anyone can do in minutes.

The Guide below is for 4 inch height Round and Square cakes only, but if you’d like the full comprehensive Guide (which includes measurements for 3 inch and 5 inch height cakes), then Download the Free Fondant Coverage PDF Guide here.
