I love cheat sheets. They’re not only handy, they’re practically essential for many graphic designers who are expected to know a never-ending list of numbers and codes: standard sizes for various applications, color hex codes, basic web languages, and, of course, myriad keyboard shortcuts for powerful graphic design software.

Unless you have a photographic memory (and you do not, my friend), there is no way you can possibly retain so much specific information with error-free recall. Looking up the information every single time is cumbersome and time-wasting. Cheat sheets make it easy for you to quickly reference the information you need so you can stop searching for answers and get back to creating. As such, here are 10 indispensable graphic design cheat sheets you should print today.
