An A7 gatefold card refers to a specific type of greeting card that is folded in a gatefold style and is sized according to the A7 paper size standard. Here's some information about A7 and gatefold cards:

1. A7 Size: The A7 size is a standard paper size used internationally, particularly in Europe. It measures 74 mm × 105 mm or 2.91 inches × 4.13 inches. A7 is often used for various stationery items like invitations, postcards, and greeting cards.

2. Gatefold Style: Gatefold is a folding style where the card is divided into three equal parts. The two outer sections fold inward, meeting in the middle to create a gate-like effect. When the card is closed, it resembles a gate, hence the name "gatefold." When opened, the recipient can see the inner part of the card.

3. A7 Gatefold Card: An A7 gatefold card is a greeting card made by folding an A7-sized paper or cardstock in a gatefold style. The finished card dimensions will be approximately 2.91 inches × 4.13 inches when folded, but twice that when opened flat. This provides a unique design opportunity, as the gatefold style allows for a larger surface area for design and content placement.

A gatefold card can be used for various occasions like birthdays, weddings, anniversaries, or any other event where a special and visually appealing card is desired. The design possibilities are endless, with the inner panels serving as a canvas for personalized messages, artwork, photographs, or any other creative elements you wish to include.
