Hi, I think you misunderstood this post. This is not about setting the font size of a text, this is a workaround to use a size box in verse (which is currently only available in widget blueprints), like using a rock if you don’t have a hammer.
In this case, a size box is being used to determine the minimum height of a text block, which means that if its text has less lines than intended, the space available will remain the same. This is useful because there is no way to set a minimum desired height for a text block
Currently there’s no way to set text’s font size of a text_block created in verse.
