Good milestone birthday party ideas start with the person, not the number. A 40th for someone who loves a dance-off looks nothing like a 40th for someone who'd rather a long dinner with old friends. Still, each big birthday has its own flavour, and the crowd it brings tends to follow a pattern.
So we've gone through them one by one, with entertainment ideas that suit the age and the guest list. You'll also find some general tips on venues and surprises at the end. Pinch whatever fits.
18th birthday
An 18th is a funny mix. It's the first legal drink, so the birthday person wants it to feel grown-up, but grandparents and parents' friends often come too. A party that starts with family and then hands over to friends can keep everyone happy.
Hire a function room with a DJ who knows what this crowd listens to. Add a photo booth or a 360 video booth, because the photos will end up on every phone in the room. And if the family's there for the first hour, a close-up magician going round the tables gives the generations something to laugh at together.
21st birthday
By 21, the guest list is mostly friends, often from uni or work, plus a bit of family. Themed parties go down well at this age: a casino night, a 'come as your favourite decade', or a cocktail masterclass before heading out.
Speeches are traditional at a 21st, and they can be brilliant or excruciating. Keep them short. A slideshow of embarrassing childhood photos usually does more work than a long speech.
30th birthday
Thirtieths often have a 'proper grown-up' feel: a nice restaurant, a private dining room, a weekend away with a big group. If it's a dinner, think about entertainment that works around the table. A magician doing table-to-table magic between courses fits nicely, as does a short quiz about the birthday person.
Fancy something a bit different? Try a private chef's table, a tasting experience or an escape room before dinner. Plenty of groups at this age want an activity, not just drinks.
40th birthday
Forties are often the biggest party since the wedding. Friends have kids, so getting a babysitter is a commitment, and people want a proper night of it. A function room or a marquee with a band or DJ is the classic set-up.
This is also the age group that loves a bit of nostalgia. A playlist from when the birthday person was 18, a dress code from that decade or a 'spot the guest from the photo' game all land well. For something a bit theatrical, a mind reader who can somehow reveal details about the birthday person's past makes a great surprise for the speeches.
50th birthday
Fiftieths tend to be more about the people in the room than the party itself. Old friends from different parts of life are meeting for the first time, so anything that helps them mix is worth its weight in gold. A roaming party magician is good at this, because they bring little groups together over something that's genuinely fun.
A sit-down dinner in a private room with speeches, then some music, is a popular format. If the birthday person's a music fan, a tribute act or a live band covering their favourite artist can turn the night into something special.
60th birthday and beyond
Sixtieths often bring together the widest age range of all, from grandchildren to old school friends. Choose entertainment that works for everyone, ideally something that doesn't need loud music or late nights to be enjoyable.
A long lunch rather than an evening party is increasingly popular, and it makes it easier for older guests and young families to come. A close-up magician, a pianist or a singer during lunch, and a slideshow or memory book, will keep things lively without making it feel like a nightclub.
Venues and practicalities
Pubs with function rooms, golf clubs, cricket clubs, village halls and hotel suites are all common choices. Check what's included, such as a bar, a PA, tables and chairs, and the latest finish time. And ask about noise limits if you're planning a band.
Book the venue first, then the entertainment. Our price guide gives a feel for what magicians typically charge, and you can see our acts on the magicians page.
Planning a surprise party (without blowing it)
Keep the guest list in one place and tell people not to mention it on social media. Give the birthday person a believable reason to be at the venue, such as a quiet drink or a family meal.
Tell the entertainer it's a surprise. Seriously. Performers sometimes contact clients by phone or email, so make sure they've got your details, not the birthday person's.
