These hour and minute hands are sold in pre-matched pairs. The minute hand measures 5-3/16" overall with a 4-1/8" sweep (measured from the center of the hole to the tip). Normally, the minute hand should be long enough to reach the outermost edge of the numbers or the minute marks on your clock face. These hands can be trimmed to fit without affecting the overall design.
If you plan to paint the hands, the black finish works perfectly as a primer. The black hands also have a white finish on the flip side, so they can easily be reversed for use with dark colored clock faces.
