"I needed a funny 21st birthday invitation but had zero design skills. I typed 'beer pong and retro neon theme' and got a sick design in 5 seconds. Sent it via group chat and everyone loved it!"

Frequently Asked Questions About 21st Birthday Invitations
Everything you need to know about designing, wording, and sending your milestone 21st birthday invites.
What should I write on my 21st birthday invitation?
* Your invitation should include the essentials: who is turning 21, date, time, location, and RSVP details. Since it's a 21st, it's also helpful to include ID requirements (if going to a club/bar), dress code (e.g., "dress to impress"), and whether drinks are provided or if it's a BYOB event.
How do I make digital 21st birthday invitations for texting?
* Simply use our AI generator, select the "Digital/Mobile" layout, and download the high-resolution PNG or JPG file. This format is perfectly sized for smartphone screens, making it easy to send via text, WhatsApp, or Instagram DM.
Is the 21st birthday invitation maker free to use?
* Yes! Birthday Card Generator offers a completely free tier that allows you to generate, customize, and download high-quality invitations. Premium features and ultra-high-resolution print exports are available with our affordable plans.
How far in advance should I send out 21st birthday invites?
For a milestone event like a 21st birthday, it is best to send out invitations 3 to 4 weeks in advance. If your party falls on a busy holiday weekend or requires travel, send a "Save the Date" 6 to 8 weeks ahead.
Can I add my own photo to the invitation?
* Absolutely! After the AI generates your initial design, you can upload your own photo (like a cute childhood throwback or a recent favorite portrait) and drag-and-drop it into the template.
What is the difference between AI-generated invitations vs. traditional templates?
* Traditional templates require you to manually fit your text into pre-existing boxes, which often ruins the design. AI-generated invitations analyze your specific text, theme, and vibe, building a custom design around your content from scratch.
Can I print my digital 21st birthday invitations?
* Yes. When you are done designing, choose the "Download Print-Ready PDF" option. This will export your file in 300 DPI high resolution with bleed marks, perfect for home printing or professional print shops.
How do I politely say "bring your own alcohol" on a 21st invite?
* You can use casual phrasing like: "BYOB - we'll provide the mixers!", "Bring your favorite bottle to help us toast!", or "We'll have some drinks, but feel free to bring your favorite beverage.
