Font size General font size: title 150 points, text 90 points.
The specific font size depends on the placement of the display board and the content of the display board (if it is necessary to highlight the text, it may need to be larger). When "pound" is used as the unit of measurement, the greater the value of "pound", the maximum value is 72 pounds and the minimum value is 5 pounds. The range of points is 1 ~ 1638, that is to say, the largest font size can be 1638, which is about 58 cm square, and the smallest font size is 1, so the three words add up to less than one millimeter wide.
1 lb = 1/72 inches = 1 cm× 1/28≈0.35mm, 150 lb, 52.5 mm (i.e. 5.25 cm), and 90 lb, 31.
