Remember, the envelope should be slightly larger than your invitation to allow for easy insertion and removal. It's also a good idea to leave some space around the edges of your invitation to prevent any damage during the mailing process.

Tips for Addressing and Preparing Your Envelopes

Once you've chosen the perfect envelope for your wedding invitation, it's time to address and prepare them for mailing. Here are some tips to help you with this process:

  • Addressing: Use a clear and legible font for addressing your envelopes. You can handwrite the addresses for a personal touch, or use a calligraphy service for a more elegant look. Make sure to include the recipient's full name and address, as well as the date and time of your wedding.
  • Postage: Ensure that you use the correct postage for your envelope size and weight. You can visit the USPS website or your local post office to calculate the postage required.
  • Sealing: Seal your envelopes with a seal or a sticker to keep them secure during the mailing process. You can also use a wax seal for an added touch of elegance.

Choosing the right wedding invitation size and envelope is an exciting step in the wedding planning process. By understanding the different sizes and styles available, you can create an invitation suite that reflects your unique style and sets the tone for your special day. Happy planning!
