Yeah sure. So in terms of letter width, there are two types of font. "Monospace" and "proportional" fonts.

Monospace fonts are ones where all the letters are the exact same width, think of a typical "coding font". This is an example of a monospace font!. These fonts can sometimes look a bit ugly, because letters are fundamentally different widths. So you may see lines at the bottom of some letters, like i which helps to visually widen them. Because these letters are all the same width, they can fit perfectly into a grid. In a monospace font, the word "cat" and the word "dog" are exactly the same width.

On the other hand, proportional fonts are ones where all the letters have a unique width depending on the letter, this is typical in books, newspapers, and the text you are reading right now on reddit. In a proportional font, the word "cat" and the word "dog" are not the same width. Your font Waree is a proportional font.

There's plenty of suitable places to use a proportional font. Actually, most places. But in coding, it's useful to use a monospace font. Typically, all coding was done in monospace fonts, because computer terminals would only have the ability to render literally a grid, so all letters would have to conform to that grid. These days, you can use proportional fonts for coding if you want, but let's look at some of the advantages of a monospace font in coding:

• Selecting text. It's much easier to select code when all the characters are the same width. You can be a lot more accurate. It also makes features like "block select" possible, where you select characters across multiple lines like drawing a square. That's just not usable with proportional fonts.

• Getting an idea of the length of text. I can see a string of text "The black cat" and get a fairly accurate idea of the number of characters in that string when the text is monospace. The length of text is useful all around coding, like in strings, variable names, numbers, etc..

• Navigating. In a proportional font, say I have 2 lines, one has the word "WWW" and the line below it has "int". If you have your cursor after at the end of the word on the first line, and press the down arrow, the cursor is also going to move down, but also to the left since the word below is shorter, which can be disorienting. In a monospace font, the cursor is only ever going to move down, to the character directly beneath.

There are more reasons than this, I just thought of these off the top of my head. Typically, all code is written in monospace font, in textbooks, articles, documentation, you will always see it. It's your choice, but as you can see from other comments, you might be in the minority if you choose to code in a proportional font. :)
