I want to give my daughter a letter on the morning of her wedding, and I don't know how to start.

Letter or speech: what goes where

A speech is for the room. A letter is for one person, read once, alone, and then kept in a drawer for forty years. That changes what belongs in it.

The letter can hold the things you would never say into a microphone: the night she was born, the year that was hard for both of you, the thing you got wrong and wish you had done differently. It can be quieter and more private than any toast. It should not repeat your speech. If you are speaking at the reception, keep the funny story for the room and the tender one for the page.

Most wedding-day letters are given in the hours before the ceremony, while she is getting ready, so she reads it with her makeup half done. Some parents hand it over in person; many ask the maid of honor or a sibling to deliver it so they are not there when it is opened. Either way, keep it to one page. She will have ten minutes, not an hour.

What to put in a one-page letter

About 300 to 400 words fits one handwritten page. A shape that works:

Open with her name and one memory from long ago, told as a small scene. Say plainly what you see in her now, with one example. Say something about the person she is marrying, kindly and specifically. Give one hope, not a list of rules. Tell her where you will be: in the front row today, at the end of the phone afterward.

Leave out advice about marriage unless you have one line that is truly yours; lists of tips read like a magazine. Leave out the cost of the wedding, the guest list fights and anything that would make her cry for the wrong reasons an hour before she walks down the aisle.

For a son, the same shape works. Many parents find that letters to sons are shorter and more direct, and that is fine. One true sentence about the man he has become is worth more than a page of praise.

Example: a letter from a mother to her daughter

Example (about 280 words, from the notes in the box above):

“Dear Emily,

You were born in an ice storm. Halfway through the night the power went out in the whole hospital, and the first time I held you it was by the light of a nurse's flashlight. I have always thought that explained a lot about you. You have never once waited for the lights to come on.

When you were six you wrote in your diary, in purple marker, ‘I will marry a man with a dog.’ I found it when we cleared out your room last spring. Ben has two dogs. You have always exceeded your own targets.

In 2019, when I was sick, you drove home every weekend for three months. You never asked whether you should. You just came, with groceries and terrible magazines, and sat with me. I am not sure I ever told you what that meant. It meant everything. It is the reason I am not worried about you today. I have seen how you love people when it is hard.

Ben is lucky. I think he knows that. I have watched him watch you across a room, and he looks at you the way your dad looked at me when we were young and broke and very happy.

I don't have advice. You don't need it. I only have one hope: keep laughing at yourself. It has gotten you through every hard thing so far, and it will get you through the ordinary ones too.

Whatever happens after today, our door is open and the porch light is on. That will never change.

I am so proud of you. Go and get married.

All my love, Mom”

Example for a son, and what the Anything format does

A shorter example, from a father to his son (about 80 words):

“Jake, I am not good at saying these things, so I am writing them down. I watched you teach your nephew to ride a bike last summer, running behind him for an hour in July heat without once letting go before he was ready. That is the kind of man you are. Sara is marrying someone patient and steady, and so is she. I am proud of you. I always have been. I just said it too rarely. Dad”

This page opens the Anything format rather than Speech, because a letter is written to one person and has no toast. With Length on Enter a word count, it writes to the number you give and runs another pass if the draft comes out more than 10% short or 20% long. Heartfelt keeps it sincere. It writes letters as continuous prose without headings, in your first person, and works from your notes; it does not invent memories, names or dates. A light red pen pass cuts stock phrases. On Pro or Pro Max, a voice saved from your own writing (at least 300 characters, two to five pieces works best), such as old cards or emails to her, makes the draft sound like the parent she knows.
