If I could only pick one term to learn as a designer it would be ‘white space.’ It makes a HUGE difference in your work when you learn how to use it. It’s so easy to want to cram a page full of text, images and design — but everything needs room to breathe. White space is helpful because it’s a great way to create hierarchy by grouping certain design elements together and separating others.
A common misconception with white space is that it’s actually white. In reality, it’s just the negative space within a design or image. Anywhere that your eye can rest is really important.
Just remember — let your design breathe!
