The A7 envelope is ideal for enclosing cards sized 5 x 7 inches. Its larger size provides a more elegant and spacious feel, making it perfect for special occasions.
• The A2 Envelope: Smaller than the A7, the A2 envelope measures 4 3/8 x 5 3/4 inches (111.1 x 146.1 mm). It is commonly used for response cards, announcements, and smaller invitations. It is a popular choice for its compact size, making it suitable for various types of stationery.

It's suitable for documents that need to be folded in half or for holding multiple sheets of paper. This is a great choice if you want to make your documents feel more substantial.

Factors to Consider When Choosing an Envelope Size

• Content Size and Folding: The size of the documents you are sending is the primary factor. Measure your documents. Do they need to be folded, or can they be sent flat? This dictates your envelope size.
• Paper Weight: Consider the paper weight. Thicker paper requires a larger envelope to avoid bulging or damage.
• Purpose of the Mailing: For professional correspondence, use No. 10 envelopes or larger. Invitations and special announcements may require A7 or A2 envelopes.
• Printing and Design: The envelope size must be compatible with your printer if you are printing addresses or designs directly on the envelope.
