Example 1: Older brother, heartfelt with laughs, about 4 minutes

566 words · about 4 min spoken

Good evening, everyone. For those who don’t know me, I’m Andre, Malik’s older brother by three years—although I like to think of myself as the wiser one, too. Malik asked me to be his best man, which means the world to me, and I promise to only embarrass him a little bit tonight.

Growing up, Malik and I shared a bunk bed in our parents’ row house. I had the top bunk for years, which is every big brother’s birthright, until Malik won it off me in a game of H-O-R-S-E. I still say he traveled on that last shot, but what can you do? Now we live just ten minutes apart and still play basketball every Sunday morning—though these days, my knees do most of the complaining.

Malik has always been the calm one in our family. He’s the guy who actually reads the instructions before trying to build the coffee table. He’s stubborn—you should see him refuse to ask for directions—but generous to a fault. If you need him at 6 a.m. with a moving truck and four flights of stairs, he’s there, no questions asked, just a quiet judgment about your furniture choices.

One story that always comes to mind: when we were kids, we built a go-kart out of a laundry basket and the wheels from Dad’s old lawnmower. Malik insisted on being the test driver—he’s always been brave—and crashed straight into Mrs. Jenkins’ rosebush. He climbed out, covered in petals, grinning from ear to ear, and shouted, “It works!” That’s Malik in a nutshell—optimistic and up for adventure, even when things get a little thorny.

Then Grace came along. I met her at our mom’s 60th birthday cookout. Within an hour she’d taken the grill tongs away from Malik, because let’s be honest, he was burning the burgers. My mom pulled me aside and said, “That one’s staying.” And she was right. Grace fit right into our family, like she’d always been there.

Since meeting Grace, Malik has changed in ways I never expected. This is a man who used to call a bowl of cereal ‘dinner’ and thought adding a banana was gourmet. Now, thanks to Grace, he makes pancakes from scratch on Sundays and actually lets himself enjoy life a little more. There’s more laughter, more warmth, and a lot fewer burnt burgers.

Grace and Malik are a great team. Grace makes the plans, Malik makes them happen, and somehow they are still speaking after putting together IKEA furniture. That, to me, is true love.

Tonight, I want to thank our parents, Denise and Robert, and Grace’s parents, Emmanuel and Ngozi, for hosting this beautiful evening. And to everyone who traveled from out of state—thank you for being here to celebrate with us. There’s someone we all miss tonight—our Nana Ruth, who taught us both to dance in her kitchen. She would have loved today, and I know she’s smiling somewhere.

Grace, welcome to the family. You’ve been one of us since that first cookout, but now it’s official. My advice: keep playing as a team, keep the Sunday pancakes going, and when you disagree, settle it the old-fashioned way—with a game of H-O-R-S-E. Malik will probably try to call bank on every shot, just so you know.

(Raise your glass) Here’s to Grace and Malik—may your love always be strong, your pancakes fluffy, and your furniture sturdy. Cheers!

What the writer told Toastful to get this speech
Speaker
Andre, best man
Relationship
Malik is my little brother; I am three years older, and he asked me to be his best man. Growing up we shared a bunk bed in our parents' row house, and I had the top bunk until he was 12 and won it off me in a game of H-O-R-S-E. Now he lives ten minutes away and we still play ball every Sunday morning.
Personality
Malik is the calm one in our family, the guy who reads the instructions before building the furniture. He is stubborn and generous to a fault.
First impression
I met Grace at our mom's 60th birthday cookout. Within an hour she'd taken the grill tongs away from Malik because he was burning the burgers, and my mom pulled me aside and said, 'That one's staying.' She was right.
How they've changed
He used to eat cereal for dinner and call it cooking. Now he makes Sunday pancakes from scratch because Grace taught him, and he laughs a lot more.
Stories
When Malik was 8 and I was 11, we built a go-kart out of a laundry basket and the wheels off our dad's old lawnmower. He insisted on being the test driver and crashed straight into Mrs. Jenkins' rosebush, then climbed out covered in petals and shouted, "It works!" Twenty years later, when I moved apartments, he showed up at 6 a.m. with a borrowed truck without me asking and carried my couch up four flights of stairs in July.
The couple
Grace makes the plans and Malik makes them happen. They are the only couple I know who can put together IKEA furniture and still be speaking afterward.
Remembering
Our grandmother, Nana Ruth, who taught us both to dance in her kitchen. She passed two years ago and she would have loved today.
Thank-yous
Our parents, Denise and Robert, Grace's parents, Emmanuel and Ngozi, for hosting tonight, and everyone who drove or flew in from out of state.
Wishes
Grace, welcome to the family. You have been one of us since that cookout, and now it is official. Keep playing as a team, keep the Sunday pancakes going, and when you disagree, settle it the way Malik and I always did: a game of H-O-R-S-E.

Example 2: Younger brother, short and funny, UK wedding

354 words · about 3 min spoken

Good evening, everyone. For those who don’t know me, I’m Rory, Callum’s little brother and, apparently, lifelong copycat. I’ve been following in his footsteps since day one—same football team, same questionable haircuts, even the same university in Leeds. I drew the line at his degree, though. There are limits.

Now, let me tell you about Callum. He’s the most organised man on planet Earth. He has a spreadsheet for his spreadsheets. The only surprise I’ve ever seen him enjoy was when his alarm didn’t go off on time.

The first time I met Aisha, she walked into our local pub quiz, absolutely demolished us all on her own, and then bought the next round. I thought, she is far too good for him. She still is, but we don’t say that out loud. Except right now. In a speech. In front of everyone.

Callum and I have had our moments. When I was seven, he convinced me our hamster, Biscuit, could understand French. So I dutifully interviewed Biscuit every night, while Callum “translated.” If you ever wondered about my GCSE results, there’s your answer. And Aisha, you may not know this, but on your first date, Callum rang me at midnight, locked out and standing in the rain. I delivered the spare key. He made me swear never to tell you, so obviously, here we are.

Since meeting Aisha, Callum now owns a houseplant that’s still alive, and the fridge is no longer colour-coded. Progress is real.

Together, they balance each other perfectly—Aisha the whirlwind, Callum the planner. Tonight, he even did six weeks of salsa lessons, which is true love if I’ve ever seen it.

A big thank you to Farah and Imran for hosting this beautiful day, and on behalf of the bridesmaids, thanks to Callum for his very polite speech earlier—no pressure on me at all.

Aisha, welcome to the family. Callum, keep your spreadsheets, but let Aisha break the rules every now and then.

(Raise your glass) Here’s to Aisha and Callum. May your life together be as well organised as Callum’s sock drawer, and twice as much fun. Cheers!

What the writer told Toastful to get this speech
Speaker
Rory, best man
Relationship
Callum is my big brother, four years older than me, and I'm his best man. I have copied him my whole life: same football team, same terrible haircut, even the same university in Leeds.
Personality
Callum is the most organised man alive. He has a spreadsheet for his spreadsheets.
First impression
The first night I met Aisha she beat our whole table at the pub quiz on her own, then bought the next round anyway. I thought, she is far too good for him.
How they've changed
He now owns a houseplant that is still alive, and he has stopped colour-coding the fridge because Aisha told him it was weird.
Stories
When I was 7, Callum convinced me our hamster, Biscuit, could understand French, and made me interview him every night for a week while Callum translated. Also, on his first date with Aisha he locked himself out of his flat in the rain and rang me at midnight to bring the spare key. He made me promise never to tell her, so this feels like the right moment.
The couple
Aisha is spontaneous and Callum plans everything, so they meet in the middle. He would do anything for her, including six weeks of salsa lessons for tonight.
Thank-yous
Aisha's mum and dad, Farah and Imran, for hosting. And on behalf of the bridesmaids, thank Callum for his kind words about them in his speech, since I'm speaking after him.
Wishes
Aisha, welcome to the family. Callum, keep the spreadsheet, but let her break the rules on it now and then.

How to structure it

  1. 1

    Open with birth order, not just your name

    Half the guests, mostly on her side, have never met you. Say you're the groom's older or younger brother and his best man in your first two sentences. Birth order is your best setup: "I've known him since the day he was born" and "he's known me since the day I was born" lead to very different jokes.

  2. 2

    Pick the childhood story your family still retells

    Most families have one story that comes out at every holiday: the go-kart crash, the haircut he gave himself, the time he ran away to the end of the driveway. Your parents will laugh before the punchline, and her family gets a quick picture of who he was. Tell it in under a minute, then say in one line which part of that kid is still in him.

  3. 3

    Show the moment you stopped keeping score

    Brothers keep score for years: who was faster, who got the front seat, who Mom said was right. Name the moment the scoreboard stopped mattering, like the night he drove out when your car broke down or the call he made when you lost a job. Older brothers often describe being surprised by him; younger brothers often describe finally being let into his world.

  4. 4

    Welcome her in your family's words

    You can welcome the bride in a way a friend can't, because you're speaking for the people at your family's table. Describe the first time he brought her home and how your parents reacted, then one thing you've seen him do differently since. Finish with the welcome itself, said to her by name.

  5. 5

    Do the best man thank-yous, as family

    Thank the hosts, her parents and anyone who traveled far; at a UK-style wedding, also thank the groom on behalf of the bridesmaids. Because you share parents with the groom, you can thank "our mom and dad" in a way no other best man can. If someone in the family has passed away, give them one gentle sentence here rather than at the very end.

  6. 6

    Say the thing brothers rarely say

    Plenty of brothers go years without saying "I'm proud of you" out loud. Turn to him, not the room, and say one or two plain sentences: what he means to you, or something you've never told him. If you need a third sentence, it's probably a joke you should cut.

  7. 7

    Get everyone on their feet for the toast

    Ask everyone to stand or raise a glass, then say both names clearly. In the UK, the best man often reads cards or messages from absent friends and family just before the toast.

Opening and closing lines

Ways to open

  • “Good evening, everyone. I'm [Your Name], [Groom]'s brother, which makes me the only person here, apart from Mom and Dad, who has seen the bowl-cut photos.”
  • “I'm [Your Name], [Groom]'s older brother. For [NUMBER] years I was told, "Be nice to your little brother." Tonight, I finally get a microphone.”
  • “Hi, I'm the younger brother. [Groom] has spent my entire life telling me what to do, so standing up here while he has to sit quietly and listen is the best gift I could ask for.”
  • “Mom, Dad, I'm sorry in advance. Some of these stories you're hearing for the very first time.”
  • “[Groom] could have picked any of his friends to be his best man. He picked the one guy he can't get rid of, because I came with the family.”
  • “Most best men can tell you how they met the groom. I can't. [Groom] was already there when I arrived, and he's been sitting in my seat ever since.”
  • “I've shared a bedroom, a car, a pile of hand-me-downs and at least one broken lamp with [Groom], so I think I'm qualified for this job.”
  • “[Bride], I've been looking forward to today for one reason: I finally get a sister who'll take my side at family dinners.”
  • “[Bride]'s family, you may be wondering who the guy with [Groom]'s nose is. I'm his brother, and I promise I got the better version.”
  • “I was [AGE] when [Groom] was born, and I was not impressed. It took me a while, but I came around, and today I couldn't be prouder to stand next to him.”

Closing toasts

  • “[Bride], you were already one of us. Today the paperwork caught up. Please raise your glasses to [Bride] and [Groom].”
  • “[Groom], being your brother was never optional. Being your best man is the best thing you've ever asked me to do. To the bride and groom!”
  • “Mom and Dad raised us to look out for each other. [Groom], now you've got [Bride] for that, and you've still got me. To [Groom] and [Bride].”
  • “We fought over the front seat for twenty years. [Bride], it's yours now, permanently. To the happy couple!”
  • “[Groom], you used to follow me everywhere. Today I'd follow you anywhere. Everyone, to my little brother and his wonderful wife.”
  • “[Groom], you taught me how to ride a bike, how to parallel park, and now how to love someone without holding back. To my big brother and [Bride].”
  • “If [NAME OF LOVED ONE] were here, they'd already be telling [Bride] embarrassing stories about both of us. We miss them today. Now please raise your glasses: to [Bride] and [Groom].”
  • “Here's to a marriage with more laughs than arguments, more "yes" than "we'll see," and far fewer fights over the remote than [Groom] and I ever had. Cheers!”
  • “To [Bride] and [Groom]: may your house be loud, your table be crowded, and your couch always open when your brother turns up unannounced.”
  • “Please stand and raise your glasses to my brother, my oldest friend, and to [Bride], who makes him better than I ever could. To the bride and groom!”

Fill-in-the-blank template

Prefer to write it yourself? Copy this and replace everything in [brackets].

Good evening, everyone. I'm [YOUR NAME], [GROOM]'s [OLDER / YOUNGER] brother, and today I also get to be his best man. For [BRIDE]'s family: I've known him [SINCE THE DAY HE WAS BORN / MY WHOLE LIFE], so I come with [NUMBER] years of evidence.

First, thank you to [HOSTS] for [WHAT THEY DID], and to everyone who came from [FARTHEST PLACE A GUEST TRAVELED FROM]. [UK-STYLE WEDDING: AND ON BEHALF OF THE BRIDESMAIDS, THANK YOU, GROOM, FOR YOUR KIND WORDS.]

When we were kids, [GROOM] and I fought about [THE THING YOU ALWAYS FOUGHT OVER]. The story our family still tells is [A SHORT CHILDHOOD STORY: WHAT HAPPENED AND HOW IT ENDED]. [MOM / DAD] brings it up every [FAMILY HOLIDAY OR GATHERING]. And he hasn't changed much: he's still [THE TRAIT THAT STORY SHOWS].

At some point we stopped keeping score. For me, it was the day [A TIME HE HAD YOUR BACK AS AN ADULT]. That's when my [LITTLE / BIG] brother became one of my best friends.

Then came [BRIDE]. The first time [GROOM] brought her home, [WHAT HAPPENED OR WHAT YOUR FAMILY THOUGHT]. Since then, he's [ONE SPECIFIC WAY HE HAS CHANGED]. [BRIDE], you [WHAT YOU BRING OUT IN HIM]. [OUR PARENTS AND SIBLINGS, BY NAME] have thought of you as family since [WHEN]. Today it's official, so from all of us: welcome.

[OPTIONAL: ONE GENTLE LINE FOR A LOVED ONE WHO ISN'T HERE, E.G. GRANDPA WOULD HAVE TOLD [BRIDE] EVERY STORY I JUST LEFT OUT.]

[GROOM], [ONE THING YOU'VE NEVER ACTUALLY SAID TO HIM]. Standing up here as your brother and your best man is [HOW IT FEELS].

So please stand and raise your glasses. To [BRIDE] and [GROOM]!

Tips and mistakes to avoid

Do

  • Introduce yourself as his older or younger brother, not just "his brother," because birth order sets up every joke that follows.
  • Pair one story from before he could drive with one from after he moved out, so the room meets both the boy and the man.
  • Choose stories your parents can laugh at too, since they lived through every one of them and they're sitting up front.
  • Send your story list to anyone else in the family who's speaking, since you and your dad can't both tell the treehouse story.
  • Use family words only you can use, like "our parents," "our old house" and "my little brother," to show what makes your speech different.
  • Ask your mom or dad to fact-check your childhood story, because they'll remember the detail that makes it land, like the dog's name or the year of the haircut.
  • Add one detail from the wedding morning, like fixing his tie or his hands shaking on the cufflinks, because as best man you saw a moment nobody else did.
  • Write the sincere line to your brother on its own card in large letters, so if your voice goes you can find your place and finish it.

Avoid

  • Don't turn a real grudge into a punchline; "he broke my bike" is funny, "he still owes me $200" is not.
  • Don't mention exes, even as a "Mom finally approves" joke, with her parents a few feet away.
  • Don't tell stories that make your parents look bad, like the time they forgot him at the gas station.
  • Don't spend three lines on "good luck with him, [Bride]"; one line is teasing, three sounds like a warning.
  • Don't stop the story at age 12; if every memory is from childhood, guests never meet the man she married.
  • Don't save stag or bachelor party stories for the speech just because you were there; your parents are in the front row.
  • Don't skip the best man jobs: thank the hosts, mention the bridesmaids if that's the custom, and lead the toast.

Frequently asked questions

How long should a best man speech for my brother be?

Aim for 3 to 5 minutes, about 400 to 650 words. That's room for one family story, one adult story, a welcome for the bride and a toast. Brothers often share the evening with a dad, a mom or a sister who's also speaking, and family speeches add up fast. If two or more relatives are giving toasts, trim yours to about 3 minutes, or 350 to 400 words. At a UK wedding you speak last, after two other speeches, so landing on time matters.

What goes in a short best man speech for my brother?

Keep it to one childhood story, one sentence about who he is now, two or three lines welcoming the bride, and the toast. Name the hosts in your thank-you and stop there. The hard part for a brother is choosing: with a whole childhood to pick from, keep only the story your family laughs at most. About 250 to 320 words works, roughly two minutes out loud. The younger-brother example on this page shows a short brother best man speech at about two and a half minutes.

How is a brother's best man speech different from a regular best man speech?

Three things change. Nobody needs to hear how you met, so you can go straight to birth order and a family story. Your parents are in the audience as witnesses, so old stories land harder, and anything unkind lands harder too. And you speak partly for the family: you can thank "our parents," welcome the bride as your new sister and name a grandparent everyone misses. If someone else is the best man, see our brother of the groom page.

Does it change if he's my older or younger brother?

Yes, the angle flips. As the older brother, you can play the protective role: you taught him things, covered for him with your parents, and now you get to say you're proud of the man he became. As the younger brother, you can enjoy finally having the microphone: he bossed you around for years, you copied everything he did, and now you can return the favor with a few jokes before admitting you still look up to him.

We fought a lot growing up. What do I say if we're not that close?

Be honest without airing grievances. Light jokes about childhood rivalry are expected and even welcome, like fighting over the front seat or the last slice of pizza. Then focus on who he is now and what you respect about him as an adult, even if it's one thing, like how he treats his bride. Never fake a closeness you don't have; a short, sincere speech beats a long, forced one.

His best friend isn't the best man. Should I mention him?

Yes, briefly. It's a kind thing to do, because his closest friend may have hoped for your job. Ask him for one story from the years you weren't around, like college, uni or your brother's first job, and credit him by name: "Jamal tells me..." It fills a gap in your material and shows the room you're speaking for everyone who loves your brother, not just the family.

Our dad is giving a speech too. How do we avoid telling the same stories?

Swap stories a week before. Your dad will probably tell your brother's childhood from a parent's view, so take the sibling stories he wasn't there for: the secret schemes, the late-night rescues, the dares. Agree on who thanks the hosts so it isn't said twice. Customs vary: in the US the groom's father often gives his toast at the rehearsal dinner instead, and at a traditional UK wedding he usually doesn't speak, with the order being father of the bride, groom, then best man.

Can Toastful write a best man speech for my brother from my own stories?
