When you’re designing a website, you must care about and design for three different screen sizes: Computer, Tablet, and Phone.
The phone is a narrow view. Your person is walking (or driving π). What’s your point? Less is more. Bold and restricted. Three seconds. Simple, simple, simple. Just what. Focused. What do you want them to do?
The tablet widens that view a bit. Your person is probably on their couch or at their kitchen table. Probably has the TV on or the kids are running around. Still simple. Still bold but less restricted. Focused, but more details. Journalism. What do you want them to know? Consumption. Information forward.
The computer is a wide view. Your person is sitting, likely in a work environment. They probably have their wits about them. What are all the things? Ten seconds. Simple, yes, but also nuanced. Who, what, why? What do you want them to know and then do?
Now turn this around on yourself.
Which screen size matters to you?
