How to Write a Letter from Santa That Feels Real

A good letter from Santa feels like it was written by someone who has been paying attention. Children can spot a generic message, but they light up when a letter mentions something real. This guide shows you how to write one that is warm, believable and quick to put together. If your child is writing to Santa as well, see how to write a letter to Santa.

Start with what you know

Spend two minutes thinking about your child’s year. You are looking for moments, not achievements. Did they help a friend, learn to swim, try a new food, say sorry without being asked, or get through a hard day with courage? Pick two or three things. Those are the heart of the letter.

Praise kindness and trying, not perfection

Santa’s job in a letter is to notice. Focus on kindness, trying hard and being brave. “I heard you kept practicing even when it felt tricky” lands better than “You were perfect all year.” The Greater Good Science Center at UC Berkeley, which shares research-based parenting practices, suggests praising the kindness itself as part of who a child is, not only the single act, and avoiding prizes as a reward for it. You can read its advice on encouraging kindness in kids.

Keep Santa’s voice simple

Santa speaks in short, friendly sentences. A few touches help: mention the elves, the reindeer, Mrs. Claus or the workshop, and let him sound a little amazed at what he has heard. You do not need clever rhymes. Warmth is what children remember. Try the builder below to see how two real moments become Santa’s voice.

Try it: build a letter

Type over the examples to see how a few real moments become Santa's voice.

Dear Mia, the elves and I have been paying attention. I heard that you shared your snack with a friend who forgot theirs, and that you stayed brave at your swimming lesson. That is real kindness, and it warms the whole North Pole. Merry Christmas! Love, Santa

How long should it be?

Short. Someone will probably read it aloud to a younger child, and older children enjoy details that show Santa has really paid attention. The Say Wishes letter holds up to 280 characters, about the length of a long text, so a few warm sentences is the right size at any age. If you want a longer letter, print it or write it by hand.

Where you are sending it	Length (sentences)	Tone
Ages 2 to 5	1 to 2	Very short, with sound words, easy to read aloud
Ages 6 to 8	2 to 3	One real moment and a playful detail
Ages 9 to 12	2 to 4	A little older, with thanks for being thoughtful

These ranges are our own rule of thumb. The Say Wishes letter holds up to 280 characters, about the length of a long text, so two or three short sentences is the sweet spot.

Things to leave out

A few small habits can turn a magical moment into a warning or an embarrassment. Keep the letter about what Santa noticed, and let the list below be your filter.

In the letter, and out of it

✓ Put in

• A real, kind moment from their year
• Santa sounding a little amazed
• A mention of the elves, the reindeer or Mrs. Claus
• Praise for trying and being brave

✕ Leave out

• Threats or the naughty list
• Promises about which presents are coming
• Details you cannot keep consistent next year
• Anything that could embarrass them in front of a classmate

Ideas by age

Ages 2 to 5. Use simple words and sound words: “Ho ho ho!” Mention toys, cuddles, singing and being a good helper. Keep it very short.

Ages 6 to 8. Mention a specific thing they did, like learning to read a favorite book or being kind to a sibling. Add a playful detail about the reindeer or the elves.

Ages 9 to 12. Treat them as a little older. Thank them for being thoughtful and for helping the younger ones. Many children at this age enjoy being part of the secret.

If your child has started to wonder

Some children begin to ask questions. You do not have to decide anything in the letter. A message that focuses on kindness and the spirit of giving works whether a child is fully believing or just playing along. Follow their lead, and be gentle.

Making it an event

How the letter arrives matters almost as much as what it says. Let your child be the one to open it. With a Say Wishes letter, the envelope appears on screen with a wax seal, and your child presses and holds the seal until it breaks. Then the letter slides out with your words in it, signed by Santa. You can send the link ahead of time to a phone or tablet, or open it together on Christmas Eve.

Before you send it

Before you send it

• I chose two or three real moments from their year.
• It is written in a warm, simple voice, as if Santa were amazed.
• It is only a few sentences long.
• Nothing in it sounds like a warning or a promise.
• I saved a copy of the link, so I can say the same thing again or write a new one next year.
