This post summarises “How Much Has The Web Really Changed?” by Vasilis van Gemert, published in Smashing Magazine on 6 May 2013. The article is worth reading in full; below is our summary of its argument and what it means for a website today.
Its central point is that responsive design is not only a layout technique. About a site’s visitors, a designer knows little more than that they are probably using a browser, so the defaults a design starts from should take as little for granted as possible.
The Assumptions That Never Really Held
Van Gemert goes through the defaults designers relied on for years and shows that most were never universally true. Phones and tablets did not create these problems; they made them impossible to ignore.
Screen Size
Fixed page widths (640, then 800, then 1024 pixels) were always arbitrary choices, and some visitors never saw the whole page. Small phone screens, and tablets that can be held either way up, ended that habit.
A Mouse
Keyboard users were always part of the audience and were often shut out. Interactions that depend on hovering fail entirely on a touch screen, and touch devices are now far too common to ignore.
Fast Connections
Average speeds did rise, but plenty of visits happen over slow or unreliable mobile data and patchy public Wi-Fi. Page weight and loading behaviour still decide whether those visitors get a usable page.
Ever-Faster Hardware
Mobile devices trade processing power for battery life and price, and people keep using old computers and phones long after designers have upgraded theirs.
Calibrated Screens
Few screens show colour accurately, and a phone used in sunlight washes out subtle gradients and low-contrast text. Contrast has to survive ordinary screens and outdoor light, not just a designer’s monitor.
What It Means for Your Website
The lesson has aged well: plan for the widest realistic range of screens, input methods, connections and devices, and test on inexpensive hardware as well as your own.

Frequently Asked Questions
What is responsive design really about?
More than layout: it means designing for people using a browser while assuming as little as possible about their screen, input method, connection or device.
Why are the old web design defaults unreliable?
They were assumptions, such as a fixed screen width, a mouse, fast broadband, new hardware and colour-accurate screens, that never held for everyone. Phones and tablets made the exceptions impossible to ignore, so the defaults need to change.
Has the Web actually changed, or just our awareness of it?
Many of the issues, such as varying screen sizes, non-mouse input, slow connections, older hardware and uncalibrated monitors, are not new. What has changed is that far more people now fall outside our old assumptions, so they are harder to ignore.
