The Quarter

Quarter Sheet cakes are, just as the name describes, approximately one quarter of the size of a full sheet cake. The dimensions are generally 9 X 12 inches and may come in single or multiple layers. Quarter sheet cakes are typically rectangular making them a great choice on which to add graphics, FrostingArt, or a nice message such as "Thanks for all your Support"

The Half

The Half Sheet cake is approximately 11 X 15 inches in size and are typically one layer, but some bakers may create two smaller layers so they can add a filling. The Half Sheet is a party size cake serving 30 to 40 people. Perfect for office celebrations and easily decorated with creative message such as - "Congratulations to the Team. Here's to Sweet Success."

The Full

The Full Sheet cake is the choice for any grand event - approximately 18 X 24 inches in size and typically one layer. The Full Sheet can serve 70 to 80 people and is a wonderful centerpiece. Perfect for grand openings or a celebration for the entire company. The Full Sheet can hold 10 to 12 words.
