Your logo has a massive impact on the perception of your organization. It’s critical to keep it looking crisp, whether it’s on your website, your email signature, or the side of a blimp. Online platforms all have different requirements. The standard size of a logo depends on which platform you’re going to use. For example, a YouTube profile photo is 800 pixels x 800 pixels; a logo for a website often has a maximum height of 100 pixels. If all you have is the website logo, it’s going to look really fuzzy on your YouTube profile!
