Kids' Birthday Cards: The Complete Guide

Kids' birthday cards: choosing one and what to write

Buying a birthday card for a child is easy to get wrong in both directions: too babyish and they're insulted, too grown up and they don't get it. Age matters more than anything else here, and it changes fast between four and fourteen.

This page sorts it out by age, gives you wording that works for each one, and links to the party, joke and games guides that usually come with the card.

Choosing a card by age

  • Under 5: big numbers, bright colours, one simple joke. They're reading the picture, not the words.
  • 5 to 8: silly beats clever. Anything with a rude-ish noise in it will be read out loud all day.
  • 9 to 12: they've worked out sarcasm and they love it. Pitch slightly older than they are.
  • 13 and up: treat them like an adult with better hair. Nothing with a cartoon bear on it.

What to write in a child's birthday card

  • Happy birthday! Officially old enough to know better, still won't.
  • Have the best day, eat too much cake, blame us.
  • Another year older and somehow even louder. Happy birthday.
  • Hope your birthday is as brilliant as you think it's going to be.
  • Happy birthday. Spend the money on something your parents wouldn't buy you.

Pin badges to slip in the envelope

A badge costs less than a party bag and lasts a lot longer.

Frequently asked questions

What do you write in a child's birthday card?

How much money do you put in a child's birthday card?

In the UK, £5 to £10 for a friend's child, £10 to £20 for a niece, nephew or godchild, more for milestones like 13, 16 and 18.

Usually around nine. After that, funny and slightly cheeky beats characters almost every time.

Do you sell cards with the age on them?
