Best Uses for 5x7 Flat Cards

Flat Card vs. Folded Greeting Card

The 5x7 size is available in both flat and folded formats. Here's how to decide:

• Flat cards (this product): Single-panel cards with no fold. Best when the design is the focal point — family photo cards, formal save-the-dates, art reproductions, and announcements where a clean single-panel layout works better.
• 5x7 Folded Greeting Cards: Double-panel cards with a center fold and interior writing space. Best for traditional greeting cards, wedding invitations with detailed inside text, and any card where recipients expect to open it and find a message inside.

Choosing the Right Flat Card Size

Our flat cards come in multiple sizes to fit different uses:

• 3.5x5 Flat Cards — Our most compact flat card size. Best for RSVPs, enclosure cards, mini art prints, and packaging inserts.
• 4.25x5.5 (A2) Flat Cards — The classic mid-size flat card. Ideal for save-the-dates, announcements, and small invitations.
• 5x7 (A7) Flat Cards — Our largest flat card size, perfect for full invitation suites, photo cards, holiday cards, and detailed designs.

Quick tip: Choose 5x7 flat cards when you want maximum design space, a premium feel, and a card that will stand out in the mailbox. The 5x7 size is also the foundation for full invitation suites — pair it with smaller insert cards for RSVPs and accommodations.

Build a Coordinated Invitation Suite

The 5x7 flat card pairs naturally with smaller cards to create a complete wedding or event invitation suite:

• Main invitation: 5x7 flat card with the primary event details and design.
• RSVP card: 3.5x5 flat card for response collection — fits inside standard A7 envelopes alongside the main invitation.
• Accommodations or details card: 4.25x5.5 flat card for hotel info, directions, or wedding weekend schedules.
• Matching envelopes: Pair the entire suite with our Matching Envelopes in White, Natural, or Kraft.

5x7 Flat Card FAQ

What size envelope does a 5x7 flat card need?

5x7 flat cards fit standard A7 envelopes (5.25" x 7.25"). When you add our Matching Envelopes to your cart, we automatically pair the right envelope size with your card order — you only choose the color.

Are 5x7 flat cards good for wedding invitations?

Yes — 5x7 flat cards are one of the most popular formats for wedding invitations, especially for couples who want a clean, single-panel design with all event details on one or both sides. The size pairs beautifully with smaller flat cards for RSVPs and accommodation inserts.

Can I print on both sides of the card?

Yes — our 5x7 flat cards are printed in full color on both sides. Many customers use the front for the main design or photo and the back for additional information, event details, or contact info.

Are 5x7 cards more expensive to mail than smaller cards?

5x7 cards in standard A7 envelopes typically qualify for standard letter-rate postage in the United States, but exact rates depend on weight and current USPS pricing. Heavier cardstocks or thick envelope contents (like multi-card invitation suites) may require additional postage. We recommend confirming postage at your local post office before mailing a large batch.
