Ruling guidelines can be a bit mind-boggling when you first start out in calligraphy, but is doesn't have to be! It's really just a formula and it's all about ratios; your x-height in relation to how tall your capitals are.
We've made a short and sweet video sharing how we rule paper for our in house script. Different script styles use different ratios so play around and find your own style. This may seem really basic but it's the key to well proportioned words! Even if we don't use lines, this ratio is still in play because we've trained our eyes to see it and write that way.
We hope this is helpful! Feel free to reach out with any questions you may have.
Peace, love and letters,
Bailey & Emma
