There are a few basic guidelines a bride should follow when designing her wedding cake. Often, the decorator designing your cake will fail to let you know these things.

1. If your cake has all tiers directly above each other, either with or without separations, your tiers should have at least 4 inches difference in the diameters. This will not only make the cake look nicer, because of the proportions, but will make the cake more stable. The possible exception to this rule is when you have a smaller cake, the top 2 tiers may have only a 2 inch difference in diameter. (For example, 6"- 8"-12".) The cake would still look nicer if the proportions were 6"- 10" - 14".
2. If the tiers are staggered and on separate pedestals, the above rule does not apply. You may have any amount diameter difference between the tiers, or all of the tiers may even be the same.
3. When delivering your cake, the tiers must all be transported separately. Depending on whether or not you have separations between the tiers, the decorator may need extra time at the reception site to assemble the cake, including adding borders and details.
4. The top tier of your wedding cake is traditionally saved for the first anniversary. This is normally included in the cost of your cake. Most decorators should give you the option of paying for and serving the top tier at the reception and offering a free tier that is ordered prior to the first anniversary, so it will be fresh.
5. Be sure to ask your decorator which items are included in the cost--delivery, floral arrangement, fountain, mirror, extra decorations, etc.
6. Stay away from dark icing colors on your wedding cake. They will bleed onto the background icing and also give your guests funny colored teeth. Also, the more color used in the icing, the more bitter the taste. The most beautiful, elegant cakes are iced and decorated all in white or ivory, with color detail brought in with ribbon or flowers.
7. Be sure your table is large enough and/or the correct shape for your cake design. Also, be sure an electrical outlet and extension cord, if necessary, are available if your cake design includes such things as a fountain or lights.
