Wedding Speech Etiquette
So before you start writing your speech, find out what's appropriate and what's not when it comes to your moment in the spotlight.
The Timing of the Toasts
At formal weddings, the toasts usually take place just after dinner, when guests are still seated and before the cake cutting ceremony. For less formal weddings, the toasts are usually offered after the couple's first dance, or before the cake is cut. Regardless of the timing of the toasts and the size of your reception, it's important to make sure that the caterers, servers, or hosts have poured champagne or another drink for all the guests before toasting begins. Some people believe that it is bad luck to toast with an empty glass.
The Length of Toasts
Everyone has a story about a wedding toast gone wrong: one that was too long, too dull, or maybe one that was more appropriate for a stand-up comedy act. A toast shouldn't run longer than 2-3 minutes. That amount of time allows you to graciously introduce yourself, say a few personal words, tell a funny story (never embarrassing, though), read a few lines from a love song or a quote from a famous author, and then conclude with a request for the other guests to join you by raising your glasses and drinking to the health and happiness of the newly married couple.
The Sincerity of the Toasts
Above all, your wedding toast should come straight from your heart. You don't want to just try to say all the right things in your toast, so you should come up with a genuine, heartfelt speech that you really mean. When you speak from your heart, people will feel it in your words and it your toast will be memorable to all that are at the wedding.
