Buying Guide
What size should you choose? For quick, budget-friendly options, 4×6 inch invitations are common and easy to mail. If you need a larger canvas for more details, consider 5×7 inch invites that fit standard envelopes.
Fill-in vs. pre-printed? Fill-in-the-blank styles let you customize each guest’s invitation, while pre-printed designs save time but may offer less personalization.
Envelope and sticker considerations. Some sets include envelopes and seals (stickers) for secure closing. If not, plan to buy envelopes separately and consider self-adhesive options for faster assembly.
Design tone and audience. For teen and tween parties, bold, playful designs work best. For formal or family gatherings, choose a cleaner, simpler layout with readable fonts.
Space for essential details. Ensure the card provides room for date, time, venue, RSVP, and any special instructions. If the card is too small, consider a separate insert or a digital RSVP option.
Durability and print quality. Check the paper thickness and finish. A glossy or semi-gloss finish can enhance colors, while a matte finish reduces glare for easier reading, especially in photographs of the invites.
