What to Say in a Best Man Speech (And What to Avoid)
Figuring out what to say in a best man speech is the part that keeps grown adults awake at 2 a.m. the week before the wedding. You know you are supposed to stand up, honor your best friend, thank his new wife, and make the room laugh — but the blank page does not tell you where any of that actually lives. This guide does. Below are ten concrete things to include in your speech, plus a short list of things to cut entirely, with exact wording you can steal or adapt.
Read it once start to finish, then come back to the sections that match what you are stuck on. A good best man speech is not clever, it is specific. Specificity is a skill, not a talent, and every tip below is a move you can copy.

The Shape of a Best Man Speech That Actually Works
Before getting into specifics, look at the architecture. A strong best man speech has five moves: an opener that earns attention, a story about the groom, a pivot to the couple, a direct address to the bride, and a closing toast. The middle eight tips below fit inside that shape.
Here's the thing: most bad best man speeches fail because they have no shape. They are a list of things the speaker remembered to mention. A speech with architecture feels like a walk through a real neighborhood. A speech without it feels like a spreadsheet read aloud.
Tip 1: Say Who You Are, Briefly
One sentence. Maximum. The room has people who do not know you, and a short self-introduction is polite. Any longer and you are eating into the actual speech.
"For those we haven't met, I'm Tom, and I've been Alex's best friend since the third grade." Done. You have named yourself, named the friendship, and set the time horizon in fourteen words. Move on.
Tip 2: Say One Specific Thing About the Groom's Character
The next sentence establishes what the speech is actually about. Not a list of traits. One trait, stated specifically, that the rest of the speech will prove.
"Alex is the kind of person who will drive four hours at midnight because a friend asked him to." That sentence is the spine of the speech. It narrows the room's attention. It tells them what to watch for. Everything that follows now lives in service of that one trait.
Tip 3: Say One Story That Proves It
A story, not a highlight reel. One story. Concrete details, real dialogue, a beginning and an end. This is the center of gravity for a best man speech, so spend two to three minutes here.
When Marcus wrote his brother's best man speech, he picked the story of the week his brother drove through a snowstorm to pick Marcus up from a bad breakup, helped him pack a suitcase, and let him stay on the couch for a month without ever asking when he was going to leave. Three specific details: the snowstorm, the suitcase, the month on the couch. That story proved the "kind of person who shows up" trait he had set up in the opening. One story can carry the whole speech.

Tip 4: Say What Changed When He Met Her
This is the pivot. You have spent three minutes on who the groom is. Now describe what happened when he met his partner. The best move is to name one specific, observable change.
"The first time I saw Alex after he met Priya, I noticed he was different in one specific way: he laughed at things he hadn't thought were funny before. That's when I knew." That line translates the abstract "he changed" into something the room can picture. Guests love this move because it makes the love story concrete.
Tip 5: Say Something Directly to the Bride
Turn your body to the bride. Look at her. Speak for at least sixty seconds to her directly. This is non-negotiable in a good best man speech. The temptation is to keep aiming at the groom and glance at the bride with a "welcome to the family" line. Do more than that.
"Priya — thank you for loving him in a way that has changed who he is. I've watched him become a better version of himself since he met you. Everyone in this room has seen it. You did that. Thank you."
That passage does real work. It credits the bride. It describes a visible change. It names the speaker's own witness to the relationship. The bride remembers this for the rest of her life.
Tip 6: Say One Honest Thing About Your Friendship
A best man speech can hold one honest, vulnerable sentence about what the friendship has meant to you. Not a paragraph. One sentence.
"I have had a lot of friends over the years. Alex is the only one I would call from jail without rehearsing what to say." That line works because it is specific and slightly self-deprecating. It also tells the truth about what the friendship is. The bride and the groom both hear it. The room feels it.
But wait — only one of these sentences per speech. Two is a monologue about your feelings. One is a gift.
Tip 7: Say Thank You to the Families
A short acknowledgment of the parents, grandparents, and the bride's family belongs near the end. Thirty seconds. Not a full thank-you tour.
"Thank you to both families — the Kim family and the Patel family — for raising two kids who were ready to find each other. And thank you for putting this room together tonight." That is enough. The parents who were about to start wondering if they had been forgotten now feel seen.
Tip 8: Say the Toast Line
End with the toast. Short, confident, and raise-glass-ready.
"I've spent my whole adult life watching Alex show up for the people he loves. Priya, you are now the person he will show up for first. I cannot wait to see what you build together. To Alex and Priya." The room stands, the glasses raise, the DJ gets a clean handoff. Do not explain after the toast line. Do not thank the room. End it.
The truth is: the toast line is the line guests will remember. Write it first. Write the rest of the speech backward from there. A clean landing beats a clever one every single time.
What to Avoid Saying
Everything above is what to say. The next two tips are what to cut. The avoid list is short and has almost no exceptions.
Tip 9: Avoid the Forbidden Stories
Three categories of story do not belong in a best man speech, no matter how funny they are:
Ex-partner stories. Any reference to a previous girlfriend, fiancée, or breakup is a hard no. This includes jokes about "we've come a long way from…" The bride has never met the ex and does not want to be introduced tonight.
Private stories. If the groom asked you never to tell it, you do not tell it at his wedding. The mic is not a loophole.
Substance or nightlife stories. The bachelor-party bar, the college blackout, the drug reference you think is funny — cut them. A wedding room spans four generations. The joke lands with two of them and alienates the other two.
Most best man speech catastrophes come from one of these three categories. Strip them out and you've solved most of the problem. For related guidance, best man speech dos and don'ts covers the avoid list in more detail.
Tip 10: Avoid the Generic Filler Lines
Certain phrases have been used at every wedding since 1985 and should be retired:
- "I've known Alex my whole life…"
- "When I first met Priya, I knew…"
- "They are the perfect couple…"
- "I don't know what he did to deserve her…"
- "When Alex asked me to be his best man, I was honored…"
Every one of these is a filler line. None of them tells the room anything specific. Replace each with a concrete scene. "I've known Alex since the night he crashed his bike into my fence at nine years old" is a specific version of "I've known Alex my whole life." Same information, ten times the impact.

FAQ
Q: What should the first line of a best man speech be?
A specific scene, a short confession, or a direct line to the groom. Not a joke about being nervous, and not "for those who don't know me." A specific opener earns the room in ten seconds.
Q: Do I have to tell an embarrassing story?
No. An embarrassing story is one option, not a requirement. A specific, warm story that shows who the groom really is works better than a roast in most rooms.
Q: How do I include the bride in the speech?
Dedicate at least a third of the speech to her and to the two of them as a couple. Name one specific thing you've noticed about how the groom changed when he met her.
Q: How long should a best man speech be?
Five to seven minutes, around 600 to 900 words. Under three feels thin. Over ten and you're losing the room, even if the material is good.
Q: What's the worst thing I can say?
Anything about an ex. Anything the groom asked you to keep private. Anything that wouldn't play in front of his grandmother. Those three filters catch almost every disaster before it happens.
