What is a Vector Logo and Why Do I Need One?

One of the most common questions I get asked when talking to a new client about logo design is, “what is a vector logo and why do I need one?”

So, here’s the scoop. First, let’s talk about common image types.

The two most common ways of storing image data are Raster and Vector. Raster images are mapped using small data points called pixels. The density of the mapped pixels (PPI) is set, and Raster images can’t be dramatically enlarged without loosing quality. Common Raster file types include JPEGs, PNGs, and GIFs.

Vector images, on the other hand, are mapped using mathematical formulas. They can be enlarged to any size without loosing quality. Common vector file types include EPS, AI, and some PDF files.

So, why do I need a vector logo? The main benefit of having a vector logo is that it can be resized for any application without loosing quality. From a small business card to a full jet plane wrap, you’re golden. Vector files are also source files that other file types can be created from. Any size JPEG, PNG and a host of other file types can be created from a Vector file.

Vector files, particularly layered EPS or AI files, are also generally more easy to edit. If you decide you want to make a change to your logo, you have the image stored in a more readily editable form. Some Raster files, like PSD files, may contain editable layers, but they are still locked into the PPI resolution they were created in.

Working on print materials and other collateral without Vector files can really slow down the design process. I’ve had to try and recreate high quality logo images from low quality Raster files on numerous occasions- a process that can sometimes take hours of design time.

If you’re looking to have a new logo designed, ask your designer if they are creating the image in Vector and if they’ll include the full Vector files. Any reputable designer should provide full Vector files as I always do. If you already have a logo, but no Vector file, some images can be recreated in Vector.

Hopefully that sums it up! If you have any questions about file types or logo design, drop me a line.
