How to Create a Wedding Hashtag Guests Will Actually Use (and Get 40 Ideas in Seconds)
Our Sweet Day Team, October 31, 2026
The morning after the wedding, the photos start to arrive: from your aunt, your college friends, the cousin who took two hundred pictures of the dance floor. A signature hashtag is how you find them all. Guests tag their posts with it, and one search brings every picture back to you.
A good one takes a little thought. Here is how to make a hashtag people remember and actually use, and how the Our Sweet Day AI Hashtag Generator writes about 40 ideas for you from your names and your story.
What Makes a Good Wedding Hashtag
- It is unique. Generic tags like #WeddingDay or #JustMarried hold millions of posts, and your photos vanish among them. Yours should belong to your day alone.
- It is easy to remember. Guests see it once on the invitation and once on a sign. If they cannot type it from memory at the reception, they will not use it.
- It is easy to spell. Avoid names with tricky spellings in the middle of a long phrase, and words that are often misspelled.
- It is short enough. Aim for under about 22 characters. Longer tags work when they read as a phrase (#FromBookshopToForever), not as a jumble of letters.
- It is readable. Capitalise each word: #MeetTheMoreaus, not #meetthemoreaus. It is easier to read, and screen readers can say it.
Ways to Build One
1. Your names with a phrase: #AnaAndLeoSayIDo, #JanAndMariaTieTheKnot
2. A pun on your surname: #HappilyEverReyes, #FinallyAFerreira, #CruzingIntoForever
3. The new name: #MeetTheMoreaus, #HelloMrsTan, #BecomingTheSantos
4. The year or the place: #AnaAndLeo2027, #SantosInLisbon
5. Your story: how you met, what you love, an inside joke. #LoveAtFirstRead for a couple who met in a bookshop, #FromHackathonToForever for two programmers
Mix and match until one makes you smile. That is usually the one.
Not Just for Weddings
Every celebration with photos deserves its own tag:
- Birthdays: #YunaTurnsThree, #AllAboardYunaTurns3, #ThreeCheersForYuna
- Debuts and milestone birthdays: #IsabelAtEighteen, #SixtyAndShiningRosa
- Christenings and baptisms: #LeoIsBaptised, #LittleLionLeo, #WelcomeLittleLeo
Check It Before You Share It
Before you print your favourite on anything, search it on Instagram and TikTok. If it already has posts from another couple, add your year or a word from your story and search again. A tag nobody else uses is the whole point.
Let the AI Hashtag Generator Write the First 40
Coming up with ideas is the hard part, so we made a tool for it. The AI Hashtag Generator is free for every Our Sweet Day host:
1. Sign in (or create a free account) and choose AI Hashtags in the menu.
2. Start from your event, and your names, surname, date and place are filled in for you. Or type them yourself.
3. Add a few keywords (how you met, the theme, what you love) and up to four vibes, such as romantic, playful or elegant.
4. Press Generate hashtags. In a few seconds you get about 40 signature hashtags made only for your day: puns on your names, your year, your place and your story.
5. Tap the ones you like to add them to your picks, and copy them all in one go. Not quite right? More hashtags brings 40 new ones, never repeating what you have already seen.
Every tag comes back clean: each word capitalised, letters and digits only, no accents, nothing rude and no spammy follow-for-follow tags. Your own names always stay as they are.
Where to Use Your Hashtag
- On the invitation website, near your names or the photos, so guests see it before the day
- On a welcome sign at the entrance and small cards on the tables
- In the thank-you message after the event, with a request to share any photos still on people's phones
- In your own posts from the engagement to the honeymoon, so the whole story sits under one tag
Pick one main hashtag and stay with it. One tag gathers everything; three tags split your photos three ways.
