Buying Guide: Key Considerations For RSVP Card Purchases
- Card size and mailing compatibility: Choose sizes that fit USPS postcard guidelines or your preferred envelope system to minimize postage and handling.
- Stock and durability: Heavier stock (e.g., 300gsm) resists creases and improves writing surfaces; ensure compatibility with your printing method if you plan to add text at home.
- Design and customization: Blank or lightly designed cards offer flexibility for handwritten responses, labels, or stamps. Consider if you want a rustic, modern, or classic aesthetic to align with invitations.
- Printing and color: If you require color printing, verify double-sided options and color quality to maintain a cohesive look with invitations.
- Space for responses: Ensure there is adequate room for guests to write names, attendance, for plus-ones, and any meal or seating notes if needed.
- Value and packaging: A larger pack offers better cost-per-card, but confirm it matches your guest count. Look for packs that include a clear mailing surface and a sturdy finish.
