A tape measure is invented that fits in an auxiliary pocket such as a credit card pocket of a wallet. The tape measure consists of a case that fits in the auxiliary pocket, a rectangular card that fits in the case, and a tape measure ribbon with a width at most half the width of the card. When the tape measure is in the retracted mode, the ribbon is wrapped nicely around the card and the wrapped ribbon is inserted in the case. To extend the tape measure, the wrapped card is removed from the case and the ribbon is unwrapped from the card so it functions as an ordinary tape measure ribbon. In an example given in one embodiment, a tape measure is sized to fit in a credit card pocket, has a thickness of less than the thickness of three credit cards, yet extends to 40 inches.
