This should be the song style that comes with the system. It may be bold, or it may be the effect after printing or copying.

As for the font size, please measure it! Although you have a reference, we don't know how big it is.

You can measure it this way. We all know that font size can be calculated in points (some people say points), 1 point ≈0.3528 mm. You can measure the width of the text (it is best to measure the total length of these six words divided by 6) to get the millimeter number and then divide it by 0.3528, and the result is the point value.

For example, the millimeter number of the small five characters is 10.5 kg, which should be ≈3.7mm, while the millimeter number of the small five characters is 12 kg ≈ 4.23 mm
