A single thumbtack, the kind commonly used to affix papers to bulletin boards or walls, weighs approximately 1 gram. In pounds, this is a minuscule 0.0022 pounds or roughly 0.035 ounces.
Thumbtacks are intentionally lightweight for easy pressing into surfaces without causing harm. Their small weight prevents them from pulling down lightweight materials.
The materials used, typically a mix of metals like steel or aluminum, make thumbtacks light. The slender yet sturdy design of a thumbtack shaft provides the needed support for attaching papers while keeping the weight low.
