Leisure articles can be slightly larger than the number of words in the content, but basically the same as the number of words in the content of the work.
Fonts are not limited. Seal cutting is mainly based on seal script, and other fonts can also be printed, but the style of the seal must not conflict with the style of the work. If you write cursive script, don't write fine Yuan Zhuwen, don't write neat regular script, and don't write the style of first aid seal ... Basically, the casting and printing styles in China are universal and commonly used.
In addition: seal cutting can not be carved by a street seal, but the seal engraving is rigid, even if the seal engraver imitates the Song Dynasty, it is artistic.
