Make it Scalable
One of the reasons simplicity is key in logo design is because simple designs are more versatile in multiple environments. Online, you want your website logo to be clear on any sized screen, even the smallest mobile devices. At times, you may have to scale up, such as on social media banners. If your website expands, you might decide to print your logo on business cards, t-shirts, or letter heads. Your logo should be able to suit all these environments whether big or small.
The Apple logo is a perfect example of this. It’s recognizable at even its smallest but can be scaled up to massive proportions.
In some cases, it makes sense to design two or three versions of your logo. The logo placed in your website header might be a bit more detailed and bold while your website’s favicon (the icon displayed by an Internet browser) might be stripped to the bare basics. Avoid making too many versions, however, since you’ll want them all to be recognizable and connect with each other visually.
