3 Type Facts You Don’t Know, But Should
2. Lining and Optical Numbers
We all just type numbers in our documents and don’t think much more about it. The numbers typed in almost all the fonts we typically use are tabular lining figures. That’s a fancy way of saying all of the numbers take the same amount of space whether it’s a “1” or “5” or even an “8.” This means when you have number on different lines, they align line to line.
This makes your spreadsheet formulas and math problems align perfectly. The number “1” lines up with the “9” on the second line. To make this work, the number “1” takes up the same space as the wider numbers like “9.” Some of the old style fonts may also have tabular old-style numbers, which again align from line to line.
There’s also proportional old-style and lining numbers. With proportional figures, each character may occupy a different amount of horizontal space. The number “1” takes up less space than a “5” or a “9.” Proportional aligning letters work very well in text. They read more like the text you’ll find them in. Like letters, the old-style numbers have ascenders and descenders — these blend the numbers in to the text. Tabular lining numbers actually stand out in proportional text and tabular old-style not quite as much.
So, which should you use? It’ll depend on why you are using the numbers. Old-style figures blend in text, while lining figures work well with all caps and when alignment is more important than blending in.
I really like the definition in Wikipedia:
“In writing and typography, a ligature occurs where two or more graphemes or letters are joined as a single glyph. An example is the character æ as used in English, in which the letters ‘a’ and ‘e’ are joined. The common ampersand (&) developed from a ligature in which the handwritten Latin letters 'e' and 't' (spelling et, from the Latin for 'and') were combined.”
Why use ligatures? They help keep letters from overlapping and can really improve legibility. Below are some ligatures you’ll find in quality fonts.
Why Do You Need to Know This?
If you’re not a graphic designer, why should you know these type facts? Look at it this way: How many times did you say in school “Why do I need to know algebra?” or “I’ll never use this in real life.” These type facts are just like algebra, you’ll use the knowledge when you least expect it.
More inspirationally, there’s Steve Jobs. After dropping out of college, he “dropped in” to classes, auditing courses that had nothing to do with a traditional degree-focused education. One of them was calligraphy. Not many years later, when launching Apple, that seemingly frivolous knowledge became a key point of difference between his and every other computer at the time. With fonts that gave users choices. Beautiful, easy-to-read letters. Type that would have earned at least a B+ in a Margie Jones’ class.
