This is the template I’ve used for my Groom’s speech in 2.5 weeks time:
In order to make sure you cover off all the things you need to with your speech, why not try writing it based on the following structure.
1Thank your new father-in-law for his kind words and for helping you (if he did) put on such a wonderful wedding.
2Thank the bride’s wider family for welcoming you into their home and lives. Even if you don’t get along particularly well you should try and find a couple of positives to say about them and the fantastic upbringing they gave your wife. This only needs to be short, but try to include as many people as possible if they deserve it.
3Turn to your own family and thank them. Praise the way they brought you up, but also try and add in a humorous anecdote about an amusing event during your childhood. Give special mention to both your and your wife’s mothers; tell them how amazing they are. You do not want to go down the soppy sentimental route, but your aim is to try and make all the mothers in the room cry.
4Move on to thank the bridesmaids for all their work, and don’t forget to praise them about how beautiful they look. Remember, you are giving this speech on behalf of your wife as well so don’t forget to use ‘WE’ instead of ‘I’. If you have any presents for the bridesmaids now is the time to give them out. A toast is normally called for as well.
5Do the same for your best man and give him the present you bought him. You may want to put in a little belittling jibe about him before he unleashes his torrent of abuse on you.
6Finish off the thank yous by naming everyone who has helped in the planning and execution of the wedding. They will appreciate being recognised.
7This is the serious bit… it is time to talk openly and honestly about your new wife and how much you love her. Tell the story of how you first met, or perhaps something else from your relationship; just make sure you give this section some real thought. Talk from the heart and try to avoid sounding like a Valentine’s Day card, if you pull it off well the whole place will be in tears and everyone will be in the palm of your hand.
8Handover to your best man to finish off the set, but make sure you do it with a little joke about how he is known to confuse fact with fantasy, or that he has a renowned imagination for the obscene – its naff, but it will get a laugh.
You should aim to fit all of the above inside 10 minutes. If you can, by the end you will have made your guests laugh, cry and cheer. Then sit back down, your grooms speech is done – now the party can start.
