Vector vs. Raster: A Little Guide

The print and graphic design industries each work with both vector and raster file types. 

So, what’re the differences?

I’ve created this little guide to help teach the basics between the two types of graphics.

Let’s go!

Vector Graphics

Vector graphics are built from mathematical formulas or paths with anchor points in order to create the image. 

Creating vector graphics is basically just illustrating an image using lines and curves. Because of this, they can be resized to humungous sizes without losing any image quality. Imagine a logo on a billboard and it is most likely vector art.

Raster Graphics

Raster file formats are a lot like LEGO creations; they consist of tiny colored blocks that work together to make a comprehensive product. Therefore, think of raster graphic creation as the process of making a larger image from many tiny digitally colored pixels on a grid. 

Due to how the image is constructed, if the file size is too small and they are resized to a very large size, then the raster image may become pixelated or blurry. Imagine what would happen if you stretched out a single lego block. It wouldn’t look right. 

An in person raster image example would be a high-resolution, framed family photo set on a wall.
