First Things First: What Are Wedding Invitation Formats?

“Format” basically means how your invitation is designed, folded, and presented.

It’s the difference between:

• A simple flat wedding invitation
• A multi-panel gatefold wedding invitation
• Or a clever wedding invitation with everything included

Each one offers a different mix of:

• Style (hello, first impression!)
• Function (where does all the info go?)
• Convenience (aka: how many pieces are we dealing with here?)

• Easy to design
• Perfect for minimalist or photo-forward layouts

• How important is budget vs. presentation?

There’s no wrong answer — just the one that feels most you.
