A good development environment is crucial to your productivity, there’s no question about it. The phrase ‘good development environment’ is subjective. For example, I’m pretty efficient using WebStorm and VisualStudio. I use vim pretty often but I’m nowhere near ‘efficient’. Matias Niemelä, on the other hand can easily manipulate text in vim.
A year or two ago, I read a blog post somewhere that suggested a font is just as important as your tool of choice. I thought, “yeah, right!”, but downloaded the font anyway. After a day of using the font, I realized how much more quickly I could read through code and how much easier it was to visually identify code blocks. I know that sentence sounds trivial, but after two years of using what I consider a better font I definitely notice a difference when I’m not using the font.
My font of choice these days is called Fantasque Sans Mono.
Here’s a screenshot comparison of Arial and Fantasque Sans Mono, both at 14pt.
The actual code tends to be wider than other fonts. In the Arial screenshot, the image stops at the 80 character vertical indicator, which can easily be seen in the Fantasque screenshot. I actually like to use a 12pt or 13pt font size with Fantasque, which gives me a little more code on screen.
Although these points may seem trivial, I challenge you to at least give a few different fonts a try. You’ll be as surprised as I was to find that subtle differences in your font can improve productivity.
