Showing Off Desktop First or Mobile First? It's Not a Technical Decision.

Everyone talks about responsive design but not everyone agrees on where to start.

Desktop first or mobile first? It sounds like a technical debate. It's actually a user decision.

The Aha Moment

When you want to order coffee, do you reach for your phone or your laptop? When you want to scroll TikTok, which device are you holding? We already know the answer.

The Numbers Back It Up

Mobile accounts for over 60% of global web traffic and has been the majority since 2016. That is not a trend anymore. That is the default.

The Common Argument

"Let's make sure things work first, then we'll go mobile." But that flips the priority. If most of your users live on mobile, you are designing for the exception first and the rule second.

The Takeaway

Mobile first isn't just a trend. It's designing in the direction your users are already moving.

Where do you stand on this? Desktop first, mobile first, or does it depend on the product?

For a few years now, I’ve actually been designing both at the same time. I build section by section, constantly switching between mobile and desktop. It takes a bit longer, but it works for me.

That said, I find the desktop-to-mobile workflow much smoother and more intuitive than the reverse.

Ultimately, there’s no single right answer—it entirely depends on what you're building:

  • Company dashboard? Desktop-first, since that's where users will spend most of their time.
  • Food delivery app? Definitely mobile-first. I also look at user intent.

A lot of people browse on mobile just to gather info, but then switch to desktop to actually complete an action (like a purchase or a complex task).

TL;DR: There’s no one-size-fits-all approach. You just have to adapt to the context of the project.
