Buying Guide
What size should I choose for an RSVP card or invitation? Choose 4-3/8 x 5-3/4 inch envelopes when your card or RSVP fits a standard A2 size or slightly smaller artwork. For bulk mailings, consider heavier paper stock (toward 110–120 GSM) for a sturdy feel and a professional presentation.
Should I pick self-seal or gummed envelopes? Self-seal envelopes save time and reduce moisture handling, making them ideal for events, wedding invitations, and large mailings. Gummed seals provide a classic closure and may be preferred for formal invitations requiring a traditional touch.
Do color choices matter? Neutral whites look classic and versatile. Colored options (yellow, blue) can enhance theme matching or brand color but may affect readability of dark ink on lighter interiors or require careful printer alignment for custom text.
Is printable envelope stock important? Yes. Printable surfaces allow you to customize with names, event details, or logos. Ensure your printer supports the envelope size and weight to avoid jams or misprints.
What is the best approach for privacy? Envelopes with internal security tint or darker interiors reduce visibility of contents and protect sensitive mail. Self-seal versions also minimize tampering risk during transit.
