When measuring components, whether door frames, window frames, or radiators, the outermost edges need to be captured. In practice, targeting a narrow or rounded edge with a laser point can be quite tricky.
💡 Pro Tip: Simply attach a small Post-it note or piece of painter's tape to the component so that it extends past the edge. This creates a clearly defined target area, allowing you to aim the laser accurately without interference or wall reflections.
