If you're looking for a font to use with your Greek, then be sure to look at the typeface options. There are many styles of Greek fonts. Some are more formal, some more casual. Most of them are designed to look good in Greek and Latin letters. There is also a variety of serif, sans-serif and script fonts available for use in Greek, as well as symbols and other characters that can be added to letters or texts. Some care must be taken when choosing the right font, since it will have an impact on the overall appearance of any Greek text you create. You should consider the following factors: weight, style and size (smaller is better). Be sure to choose one that fits your needs.
Depending on the style of letters chosen, you may also want to consider italic or bold text faces. These can be especially useful when you're writing a letter or reading out loud in Greek.
