A shrink-tubing measurement guide has a flexible strip with a measuring surface and a measurement indicator. Bands on the measuring surface form a tubing size indicator gauge, with each band having a band-specific indicium different from any adjacent band and associating a specific size of shrink tubing. The tubing size indicator gauge has a measuring surface layout based on a circumferential difference between a hand tool body and a hand tool end being compared to a predefined value, where the bands are either aligned end to end along the measuring surface or progressively-staggered with at least one end of each band extending beyond an adjacent band. The flexible strip is configured to be wrapped around a hand tool body of the hand tool with the measurement indicator aligning with at least one of the plurality of bands, where each band-specific indicium identifies a specific shrink tubing size.
