If you use Generate Covers, this will adjust your cover profile based on the length of a title - no need to regenerate when the text runs off the image
Code:
[archiveofourown.org]
generate_cover_settings:
${title} => .{1,18} => AO3-ShortTitle
${title} => .{60,} => AO3-SmallText
${title} => .{30,} => AO3-MediumText
