Calligraphy relies on precise proportional relationships between nib width, letter height and line spacing. Each script has its own set of ratios, and getting these right is the difference between amateur and professional lettering.
The nib width calculator determines the correct nib size for your desired x-height based on the nib-width ratio for your chosen script. Our guideline calculator generates precise measurements for x-height, ascender, descender and interline spacing.
For project planning, the text layout calculator works out how much text fits on a page with your chosen nib and spacing, while the writing speed calculator estimates how long a project will take based on text length and script complexity.
