Pinterest collections dedicated to a theme are called boards.
A board is Pinterest’s main organizing space: users save individual Pins—images, videos, products, recipes, or links—into boards built around an interest or project. Examples might include wedding ideas, vegetarian recipes, travel destinations, or interior-design inspiration. Pinterest itself describes boards as collections for Pins, making “boards” the platform’s canonical term rather than a generic description.
Boards can be public, private, or collaborative. Private boards are visible only to their owner and invited collaborators, while group boards let multiple people add and organize Pins. A single board can also contain sections, which divide a broad theme into smaller topics. For example, a “Vacation Planning” board could have sections for hotels, packing lists, and activities.
A common mix-up is confusing a board with a Pin. A Pin is an individual saved item; the board is the themed collection that holds it. Pinterest’s name comes from the idea of pinning items to a virtual bulletin board, extending a familiar physical organizing metaphor into a visual-search platform.
