Pop-up Valentine cards are offered in a range of sizes. Common showings include small greeting-card sizes (about 4.75" x 6.13"), a typical card size around 7" x 5", and larger or jumbo options up to about 14" x 10".
Popular pop-up Valentine designs include floral bouquets, heart- or romance-themed messages, novelty 3D sculptures (for example, a car with a heart), and licensed character or superhero pop-ups, among other creative 3D styles.
Many pop-up cards include a blank notecard and an envelope for writing a message. Some also include a removable note tag or similar insert you can write on and tuck into the card or attach to a gift.
Pop-up cards are typically made from premium or high-quality cardstock with laser-cut details and intricate paper engineering. Some listings specify recycled or eco-friendly materials, and certain products note that a purchase supports tree-planting programs.
Some pop-up cards are designed as keepsakes or displays. For example, jumbo flower pop-ups may include a detachable paper bouquet for display, and other 3D sculptures are described as displayable keepsakes.
Package options vary: many pop-up cards are sold individually (quantity 1), some come in sets of 2, and favor boxes are often sold in bulk packs—for example, a listing showing 25 boxes per pack.
The 3D effect is achieved through precise paper engineering—laser-cut shapes and intricately folded panels made from premium cardstock. These techniques allow cards to fold flat for mailing and spring into detailed three-dimensional sculptures when opened.
The favor boxes measure about 2" x 2" x 2" and are commonly sold in packs (one listing shows 25 boxes). Minor assembly is required; the listing also recommends using wrapped candies or liners to avoid staining the boxes.
