crystal cake banding
i found this and thought it could be helpful. you have to get the diameter of each tier of your cake though.
ROUND CAKES
Formula: Circumference = 3.14 x Diameter
EXAMPLE:
TIER DIAMETER MULTIPLY BY AMOUNT OF RIBBON NEEDED (INCHES)
TIER 1 6 INCH TIER X 3.14 = 18.84 - ROUND UP TO 19 INCHES
TIER 2 10 INCH TIER X 3.14 = 31.40 - ROUND UP TO 32 INCHES
TIER 3 14 INCH TIER X 3.14 = 43.96 - ROUND UP TO 44 INCHES
Now add the amount of ribbon needed for all tiers together
19 + 32 + 44 = 95 INCHES
To determine the number of yards needed for the cake in the above example, we now divide the number of inches by 36 and round up:
95 divided by 36 = 2.64 yards of ribbon - Round up to 3 yards
SQUARE CAKES
Formula: Perimeter = 2 x Length + 2 x Width
EXAMPLE:
TIER LENGTH X 2 PLUS WIDTH X 2 = AMOUNT OF RIBBON NEEDED (INCHES)
TIER 1 6 IN X 2 = 12 + 6 IN X 2 = 12 = 24 INCHES
TIER 2 10 IN X 2 = 20 + 10 IN X 2 = 20 = 40 INCHES
TIER 3 14 IN X 2 = 28 + 14 IN X 2 = 28 = 56 INCHES
Now add the amount of ribbon needed for all tiers together
24 + 40 + 56 = 120 INCHES
To determine the number of yards needed for the cake in the above example, we now divide the number of inches by 36 and round up:
120 divided by 36 = 3.33 yards of ribbon - Round up to 4 yards
