When starting a sentence in Celtic, what is the recommended height for the first letter?

In Celtic calligraphy, the first letter of a sentence often serves as a significant focal point and is typically enlarged to create a decorative and visually appealing entry into the text. The recommended height for this initial letter being two pen widths taller than the other letters is based on both aesthetic traditions and practical readability. This height creates a clear distinction, guiding the reader's eye and emphasizing the beginning of a new thought or idea.

Having the first letter stand out in this way also reflects the historical practices seen in illuminated manuscripts, where larger initials would often be highly decorated. This custom not only enriches the visual impact of the writing but also aligns with the idea that the opening of a sentence should capture attention.

The other options suggest lesser or greater height adjustments, but the choice of two pen widths strikes a balance between making the first letter prominent enough to stand out while maintaining harmony with the overall text. This understanding of proportions in calligraphy is fundamental for anyone looking to create work that is both beautiful and coherent.
