How to write an 18th or 21st birthday speech

Your child is turning 18 or 21 and you have to say a few words in front of their friends. The aim is simple: make them feel proud, not mortified. Here is a structure you can fill in tonight.

The five-part structure

  1. Welcome (two or three lines). Thank everyone for coming, especially their friends, and say you will be quick.
  2. One childhood story (short). A moment that shows who they were even then: determined, funny, kind or fearless.
  3. Who they are now (the main part). Two things you admire about the adult they are becoming, with a real example of each.
  4. A few words straight to them (a few lines). What you are proud of and what you wish for them next, whether that is university, work, travel or just being happy.
  5. The toast (one line). Ask everyone to raise a glass and say their name.

Frequently asked questions

How long should an 18th or 21st birthday speech be?
Two to four minutes is plenty. That is roughly 300 to 500 words. The guests are mostly young and want to get back to the party, so short and warm beats long and detailed.
Who usually gives the speech at an 18th or 21st?
Usually one or both parents, sometimes with a brother, sister or best friend saying a few words too. If two parents are speaking, split the stories so you do not tell the same ones.
How embarrassing is too embarrassing?
One gentle childhood story is fine and expected. Anything about first relationships, bodies, toilet training or a time they got in real trouble is too far. If you would not want it said about you in front of your friends, leave it out.
Should I show baby photos?
A few photos on a screen can be lovely, but keep them separate from the speech and check with the birthday person first. Some love it and some would rather the floor swallowed them up.
Can two parents give one speech together?
Yes. Take turns by section: one does the welcome and childhood story, the other does the grown-up part and the toast. Practise once together so the handover is smooth.
