Celebrating 100 Years
Turning 100 is no ordinary milestone. It is a once-in-a-century achievement that deserves a celebration as extraordinary as the person at the centre of it. Whether you are planning a grand gathering for a beloved grandparent, an intimate tea party for a great-aunt, or a community celebration for a local legend, a 100th birthday is one of life’s most special occasions — a chance to honour a lifetime of memories, milestones, and the people who made them.
Not sure where to start? Don’t worry. This guide brings together the very best ideas for themes, decorations, food, entertainment, and meaningful touches to make your centenarian’s big day truly unforgettable.

Things to Consider Before You Start Planning
Before diving into balloons and bunting, it’s worth thinking about a few practical things:
What does the birthday person actually enjoy? A big, noisy party might not suit everyone. Some people would love a room full of family and old friends; others might prefer something quieter and more personal. Let their personality lead the way.
Where will the party be held? Consider accessibility — for a 100-year-old, comfort matters. Whether it’s at home, a village hall, a care home common room, or a country house hotel, make sure there is plenty of comfortable seating and easy access.
How much energy do they have? Keep the day relaxed, with no pressure to be “on” for hours. A shorter, well-paced celebration is far more enjoyable than an exhausting marathon.
Who is coming? A 100th birthday often brings together several generations. Think about how to make the day work for everyone — from great-grandchildren to old friends who may also have mobility needs.
Party Themes for a 100th Birthday
Choosing a theme makes planning much easier and gives the whole celebration a lovely sense of cohesion. Here are five ideas that work beautifully for a 100th birthday.
1. Vintage 1920s — Party Like It’s 1926
Since a centenarian born in 1926 grew up in one of the most glamorous decades in history, why not celebrate where it all began? The Roaring Twenties were all about jazz, flapper dresses, feathers, pearls, and Art Deco style — and it makes for an absolutely brilliant party theme. Think gold and black colour schemes, a gramophone playlist, and guests encouraged to dress up.
You can find gorgeous 1920s-themed party stationery, invitations, and decorations on Zazzle — including personalised options that make everything feel extra special.
You could get some personalised party stationery like these to make it special.
Try an editable template from Etsy, you’ll find lots to choose from.

2. Through the Decades
This is one of the most meaningful themes you can choose, because it tells the story of an entire life. Decorate each table or area of the room with photos, props, and memorabilia from a different decade — the 1930s, 1940s, 1950s, and so on — building a visual journey through 100 years of history. Guests of all ages will find something to connect with, and it sparks wonderful conversations.
A customisable “Through the Decades” invite sets the tone perfectly and gets guests excited before they even arrive.
This bundle from Etsy – A Century in Review: 1920s to 2020s – is full of trivia and facts. It would work great for a through the decades theme.
Check out places like zazzle where you can make loads of things to make the party extra special – like this poster, which you fill with photo of them through the years, it would make a brilliant party decoration as well as gift.
3. “100 Years Loved” Afternoon Tea or Garden Party
There is something quintessentially British about an afternoon tea party, and for a 100th birthday it feels just right. Whether you hire a venue, host it at home, or book a private room at a favourite local café or hotel, the combination of finger sandwiches, scones, cake stands, and a pot of good tea creates an atmosphere that is both elegant and wonderfully relaxed.
If the weather is kind, a garden party setting adds a lovely touch — bunting, floral centrepieces, and gentle music drifting across the lawn.
If you have access to a nice garden, a sophisticated garden party, or perhaps an afternoon tea party somewhere special.
4. Memory Lane
Similar to the Decades theme but more personal — this one is all about their life rather than history in general. Gather old photographs, letters, tickets, programmes, and keepsakes, and create a timeline display that tells their unique story. Ask family members in advance to contribute items and anecdotes. A “Did You Know?” board with fun facts about the year they were born adds a lovely touch.
Use their photos and memories to create a timeline – a bit like the decades party but more personal.
This game would be ideal to play at such a party.

5. Royalty for a Day
Make them feel truly regal. A throne-style chair adorned with flowers, a personalised crown or tiara, gold and regal purple decorations, and perhaps a toast in their honour — this theme is all about making them feel like the extraordinary person they are. It works especially well if there is a naturally theatrical or grand quality to their personality.

Tips:
Keep the event relaxed with plenty of seating
Offer a quiet area for guests to chat one-on-one
Play soft music from their youth for atmosphere
Decorations for a 100th Birthday Party
Great decorations do not need to be expensive — they just need to be thoughtful.
Birthday badge: Start by pinning on the guest of honour. A personalised “I am 100!” badge is a simple but delightful touch and makes for great photos. These ‘Made in 1926’ badges are retro and fun.
Balloons: You cannot go wrong with balloons. Star-shaped gold and silver balloons, or large number “100” foil balloons, look stunning and are easy to find online and in party shops.
Birthday banner: A personalised “Happy 100th Birthday” banner in gold and black looks classic and celebratory. You can order printed ones online or make your own with craft paper and ribbon.
Photo displays: This is where the real magic is. Print out photographs from across their life — childhood, early adulthood, middle age, and recent years — and display them on a pinboard, hang them on a string of fairy lights, or arrange them in frames across a dedicated “memory table.”
Memory jar: Set out a large jar with slips of paper and pens so that every guest can write a memory, a wish, or a message. It becomes a beautiful keepsake the birthday person can return to again and again. Look for personalised printed jars on Etsy and Not on the High Street.
Table centrepieces: Personalised luminary decorations, flower arrangements in their favourite colours, or small photo frames at each place setting all add a lovely personal touch.
Food and Drink for a 100th Birthday Celebration
The cake: Every birthday needs a cake, and a 100th birthday deserves a showstopper. Whether you bake it yourself, order from a local bakery, or pick up a beautiful plain cake and personalise it with a glittery “100” cake topper, this is the centrepiece of the food table. One hundred candles is, understandably, a fire hazard — a single sparkler candle or a decorative “100” topper works perfectly.
You are not allowed to have a party without a birthday cake – and you can turn any cake ito a 100th birthday cake with a cake topper – like this glittery one here.
Nostalgic sweets and treats: A centenarian would have been a child in the 1930s — so a box of retro British sweets is both a lovely decoration and a brilliant conversation starter. Pear drops, sherbet lemons, Black Jacks, and Fruit Salads will bring back the sweetest memories.
They would have been a child in the 1930’s so some sweets and treats from that era should bring back some fond memories – this box is just the thing, and it make a great gift too.
Afternoon tea spread: Whether you cater this yourself or order an afternoon tea in a box (a brilliant option, especially if the celebration is more intimate), the classic combination of finger sandwiches, scones with clotted cream and jam, and a selection of mini cakes and pastries is hard to beat.
These afternoon teas in a box are quite handy – their great for gifting, or going on a picnic – maybe it’s just the two of you having a tea party in their room.
Drinks: A glass of something fizzy for the toast is a must — prosecco, elderflower pressé, or a retro pink lemonade all work well. If there are guests of varying ages and abilities, make sure there are plenty of non-alcoholic options too.
Food labelling: If guests have dietary requirements — which is very likely across several generations — clear, simple food labels are a small but very considerate touch.
Entertainment and Activities
Music: This is one of the most powerful tools you have. Music from their youth — their teens and twenties, so roughly the 1940s — creates an immediate emotional connection and sets a beautiful atmosphere. Compile a Spotify playlist, dust off some old vinyl, or if budget allows, hire a live musician or small jazz ensemble. Even a family member who plays guitar or piano can make a world of difference.
Play some music from an era that they enjoyed – they probably want to hear music from when they were in their teens or twenties – like this 1940’s nostagic collection.
A live band would be even better if you can manage it.
Memory slideshow: Gather photos and short video clips from family members in the weeks before the party and compile them into a slideshow. Play it on a screen or television with music in the background. This is one of the most moving and joyful parts of any milestone celebration — and it’s just as fun to put together as it is to watch.
A slideshow of memories with family commentary would be great – so get a big screen ready – this is great fun for you to make as well.
Speeches and stories: Invite a handful of family members and close friends to share short stories or memories. Keep it warm and light — funny anecdotes are especially welcome. Encourage guests to write their stories in a guest book too, so nothing is lost after the day.
A personalised quiz: A quiz all about the birthday person — their life, their favourite things, the era they grew up in — is a wonderful icebreaker and gets all generations involved. You can buy ready-made 1920s or 1940s era trivia quizzes, or make your own using facts and stories from their life.
A trivia quiz is a fun thing to do – there are loads to download – like this one. Or you could make up your own using information about the birthday boy or girl.
Guest book: A beautiful hardback guest book in which every guest writes a message is one of the most treasured keepsakes from any big birthday. Choose one that suits their personality — elegant gold lettering, floral prints, or something funny and personalised.
Speeches and stories from family would be lovely. You could also include a guest book, which people can write in, some of these stories could be read out too.
A Letter of Congratulation from the King
This is one of the most special and uniquely British touches you can arrange for a 100th birthday. The Palace sends a congratulatory card from His Majesty the King to anyone in the UK turning 100. You need to apply in advance — visit the Royal Household website to find out how.
A word of caution: only arrange this if you know they would genuinely love receiving it. If they have strong feelings about the monarchy — in either direction — it’s worth thinking about whether this would bring joy or cause a difficult moment on an otherwise lovely day. You know them best.
Getting the Community Involved
If the birthday person has been a fixture of their local community for many years, there are some lovely ways to involve the wider world in the celebration:
- Contact the local newspaper — many still run birthday announcements and would love to feature a centenarian
- Reach out to their local church, community centre, or club to see if a special mention or small celebration could be arranged
- Ask a local primary school if children could make birthday cards — a bundle of handmade cards from local children is an incredibly touching gesture
- Share the news on community Facebook groups or local noticeboards — you might be surprised how many people want to send their good wishes
Create a Memory Book or Video Tribute
Ask family and friends to share favorite memories, stories, and photos. Compile these into a scrapbook, printed book, or even a video montage. This becomes a treasured keepsake they can enjoy again and again.
Bonus: If loved ones can’t attend in person, this is a beautiful way for them to be part of the day from afar.
You could create a personalised cover for your book, like this one available here.
“100 of Their Favourite Things”
This is a brilliant and playful idea that can be adapted in so many ways:
- 100 cupcakes or cookies, decorated in their favourite colours, displayed on a tiered stand
- 100 photographs printed and hung on a display wall or strung on fairy lights
- 100 flowers in a spectacular bouquet in their favourite bloom
- 100 messages of love — ask friends and family to each submit a short message, print them out, and display them or bind them into a booklet
- 100 memories — collect one favourite memory from each of one hundred people in their life
It turns the number itself into something beautiful rather than simply something to count.
Maybe you could have a song created for them – take a look at Custom songs.
Setting Up a Legacy Table
A legacy table is one of the most meaningful additions to any milestone birthday party. It is a dedicated display space that celebrates the life they have lived — not just as a “party decoration” but as a genuine tribute.
Items to include:
- Old photographs from different life stages
- Medals, certificates, or awards
- Letters or postcards they have kept
- Heirlooms or objects that tell a story
- A written timeline of key life milestones — where they were born, when they married, significant moments in history they lived through
- A “Did You Know?” board with fascinating facts about 1926 — the year of their birth
This table becomes a focal point for conversation and a wonderful way for younger generations to connect with their history.
Make some cupcake toppers for your cupcakes like these.
Intimate Celebrations: When Smaller is Better
Not everyone wants a big party, and a 100th birthday is no exception. If the person you are celebrating is more private, more easily tired, or simply happiest in quiet company, a smaller, gentler celebration can be just as meaningful — often more so.
Ideas for an intimate 100th birthday:
- A beautiful afternoon tea for close family at home
- A visit from their favourite people, staggered across the day so it doesn’t become overwhelming
- A garden picnic if the weather allows (and in the UK, fingers crossed!)
- A serenade from a local choir, musician, or even a family member
- A quiet evening watching favourite old films or television programmes with loved ones nearby
- An afternoon tea in a box, delivered to their room if they are in a care setting
Sometimes the simplest gestures bring the biggest smiles. A hand-delivered bunch of their favourite flowers, a beautifully written card, and an hour of good company can mean more than any party.
These retro style party invitations are just the thing for a 100th birthday party.
Present them with this sash, make them feel good about themselves and loved.
Make It Personal
The very best 100th birthday celebrations are the ones that feel like them. Think about who this person really is and let that shape everything:
- If they love gardening: create a mini flower show or fill the room with blooms from the garden
- If they love baking: host a family “Great Nana Bake-Off” where everyone brings a dish they’ve inspired
- If they are a storyteller: hold a family storytelling circle where everyone shares a favourite memory of them
- If they love music: build the whole celebration around the songs and artists they have loved throughout their life
- If they are a cricket fan, a knitter, a poet, a traveller: find a way to celebrate that specific passion
A celebration rooted in who they actually are will always feel more special than a generic “100” party.
