Yeelight Lighstrip Plus - LED strip trimming

Hey, I’m thinking about buying the Xiaomi Yeelight Lighstrip Plus 2m, unfortunately the led strip is only available in the 2m version and I need 1.5m, I know that the tape can be cut in the places where the scissors are drawn, my only question is how many centimeters are these points in which you can cut the tape? Sorry for my bad English, but I’m from Poland.
