Fonts called “Irish,” “Gaelic,” or “Celtic” might not be historically accurate to the time of St. Patrick, but they still convey the point. The Celtic font is a broad category for any style of font associated with Celts and Ireland’s writing. Some Celtic fonts are calligraphic or simple sans serif fonts adorned with Celtic knots or other Irish symbols. Dingbat symbols with a Celtic or Irish theme are often part of this category.

Celtic-Style Fonts

Irish-looking fonts you can use include uncial, insular, Carolignian, blackletter, and Gaelic. Uncial and half-uncial scripts developed around the same time and look similar. Later styles had more flourishes and decorative letters. Different styles of uncial writing developed in various regions. Not all uncials are Irish; some look quite different from others.

Free Uncial Fonts

A few free uncial fonts are available, including JGJ Uncial by Jeffrey Glen Jackson. Its uppercase letters are a larger form of the lowercase letters, and some punctuation marks are included.

Uncial Fonts to Buy

One of the largest font suppliers, Linotype, features Omnia Roman by K. Hoefer. This all-capital typeface offers a few alternative letterforms.

Free Insular Fonts

Try Kells SD by Steve Deffeyes, which is based on the lettering from the Book of Kells manuscript dating from A.D. 384. The font has uppercase and lowercase letters, including the insular “G” and “g,” dotless “i” and “j,” numbers, punctuation, symbols, and accented characters. Rane Insular by Rane Knudsen is based on Knudsen’s handwriting combined with an Irish insular script. The font set includes uppercase and lowercase letters, numbers, and some punctuation.

Insular Fonts to Buy

My Fonts offers 799 Insular by Gilles Le Corre. This font set is inspired by the Latin script of the Celtic monasteries of Ireland. This slightly irregular typeface includes uppercase and lowercase letters with the insular “G,” dotless “i,” numbers, and punctuation.

Free Carolingian Fonts

Two free Carolingian-type fonts are available through dafont.com: Carolingia by William Boyd, which has uppercase and lowercase letters, numbers, and punctuation; and St. Charles by Omega Font Labs. St. Charles is a Carolingian script-inspired font with extra-long swooping strokes, numbers, some punctuation, and identical uppercase and lowercase letters. It comes in six styles, including outline and bold.

Carolingian Fonts to Buy

For a modern take on the Carolingian script, look to Carolina by Gottfried Pott from My Fonts. Unlike the rounded letters of the uncial and Carolingian scripts, blackletter has sharp, straight, sometimes spiky strokes. Some blackletter styles have a strong association with the German language. Today, blackletter is used to evoke an old-fashioned manuscript feel. 

Free Blackletter Fonts

Free blackletter fonts include Cloister Black by Dieter Steffmann, which has uppercase and lowercase letters, numbers, punctuation, symbols, and accented characters. Minim by Paul Lloyd offers regular and outline versions, uppercase and lowercase letters, numbers, and some punctuation.
