16.4 feet, with a 32.8 feet option.
Wyze Light Strip and Wyze Light Strip Pro are available in two sizes: 16.4 feet and 32.8 feet. The 32.8-foot strip is two 16.4-foot rolls with a controller in the middle (not one 32.8-foot-long strip).
Be sure to take measurements of your space before ordering. You can trim the light strip to fit any space, but those unused portions cannot be reattached or used.
