The short answer
Three to five minutes, roughly 400–650 words, in five parts: thank-yous, a welcome, your story, something about her, and the toast. The room already wants to hear from you — you're not auditioning, so don't overload the structure.
Part 1: The thank-yous (60–90 seconds)
This is traditionally the groom's job, so do it early and keep it moving: both sets of parents (and anyone who contributed to the day), the bridal party, and anyone who's travelled far. Name people specifically rather than listing categories — 'thank you to Margaret, who made every napkin in this room' beats 'thank you to everyone who helped'.
The common mistake is letting this section balloon into five minutes of admin. If someone deserves a real tribute, one sentence each is plenty.
Part 2: The welcome (2–3 lines)
Welcome everyone to the celebration and set the tone: light, warm, and honest. This is also the natural place for a gentle joke about the day, the nerves, or the best man's upcoming speech — a small laugh here buys you enormous goodwill for the rest.
Part 3: Your story (90–120 seconds)
One story about the two of you — how you met, or the moment you knew, or the worst idea she ever saved you from. Choose the one that's true, specific and that she's happy being public; tell it with the details that make it real, and let it show why you're marrying her.
This is the part guests actually remember, so it's the part worth the most of your word count. One story told properly beats three told in a rush.
Part 4: Something about her (30–60 seconds)
This is the heart of the speech, and it should be plain-spoken rather than poetic. What is she actually like, and what has she changed in you? Two or three sincere sentences — the kind you'd be comfortable with her hearing again in twenty years — outperform every stock compliment ever written.
Part 5: The toast (15 seconds + a pause)
End on the couple: short, warm, and addressed to both of you. 'Please raise your glasses — to Sophie and Dan.' Then pause for the glasses before your final line. Practise the timing of the pause; it's part of the toast, not dead air.
What to skip
The groom's speech is the one role with real traditions to respect, so skip:
- Sweeping generalisations about marriage — 'the secret to a happy marriage is...' lands as cliché
- Anything about the stag do that needs explaining
- Roasting the bride — gentle teasing about the groom is fine; the bride is off-limits
- Reading your speech from your phone — big printed text, or Wedding Mode
Part 3 and 4, connected
"Three years ago, Priya agreed to a first date at a curry house I maintain is the best in Manchester. I ordered a phal to impress her; she ordered the mildest thing on the menu and has been gently saving me from my own worst ideas ever since. She is the calmest person in every room, including this one — and marrying her is the only idea I've ever had that needed no saving."
