The best man speech is one of the most anticipated moments of the day. It's also one of the most reliably misjudged. Knowing what to include is useful. Knowing what to leave out is essential.
What a Speech Smith speech looks like
A short sample — your speech will be personalised to your stories and people.
Three opening lines that follow the rules: 1. "Good evening. My name is Jack. I'm Tom's best man, and I've been specifically asked not to mention three things tonight. I'm going to mention two of them. The third one — well, Tom will know why I've left it out." 2. "Right. I'm Ben. I've known Will since we were eleven. In the interest of full disclosure, I have prepared this speech. I have also rehearsed it. I've even timed it. Will has been very uncharacteristically prepared about his own wedding. I'm trying to match the energy." 3. "My name is Sam. Before I start, I want to be clear about what kind of best man speech this is. It is not the kind where I make the groom regret choosing me. It is the kind where I make him glad he did. The difference, I've learned, is about three stories and the decision to cut all the others." --- Good evening. I'm Sam, and I've written and rewritten this speech four times. The first version was too long. The second was too roast-y. The third was so careful it had no jokes at all. This one — I think — is the one. I'll know in about seven minutes. Here's what I've learned writing it: the best speeches are about one thing. Not about everything. One story. One quality. One reason why the couple in front of you are correct for each other. My one thing about Jamie is this: he is the most reliable person I know. Not in a dull way. In the way where, when something matters, he shows up. I've tested this more times than I should admit. And when I met Sophie, I understood why he'd been saving that reliability for something worth it. Jamie, you've been making excellent decisions since you chose to be my friend at eleven. This is the best one yet. Ladies and gentlemen, to Jamie and Sophie.

What makes this speech work
Every detail you share becomes part of your speech. Here's what to think about.
DO: tell one story properly rather than summarise ten
A speech built around one well-told story beats a speech that races through ten highlights. Choose the story that reveals his character best and tell it in full — names, detail, what he said.
DO: clear it with the groom beforehand
Any story that could embarrass him in front of his in-laws should be pre-approved. Not all of it — keep some things a surprise — but anything with genuine risk, run past him first.
DON'T: mention ex-partners
One brief gentle reference is the absolute maximum. Multiple mentions, or anything analytical about the previous relationship, will make the bride uncomfortable and the room awkward.
DON'T: go over eight minutes
The sweet spot is five to six minutes. Eight is acceptable. Anything over that and you're asking too much of the room regardless of quality. Time it and cut accordingly.
DON'T: end on a joke
End on the thing you actually mean. The final line is the one people remember. A sincere, specific toast is always better than a punchline as a closer.
Frequently asked questions
Running too long. Speeches that go over eight minutes almost always feel that way — even good ones. The second most common is too many embarrassing stories without enough warmth to balance them.
Not necessarily. Keep most of it a surprise. But any story with genuine potential to embarrass — especially in front of people he's never had that conversation with — should get a quiet pre-check.
Yes. Everyone does and no one minds. Having notes and using them is professional, not unprepared. The goal is good delivery, not a performance without pages.
The toast. 'Ladies and gentlemen, to [groom] and [bride]' is all you need. Everything before it should have built to a point where that line lands with genuine warmth.
