Built for your screen · Australia
Most websites are “responsive”: two or three width rules, and whatever falls between them is what the maths produced. We work the other way round: every screen below is a size we open, measure and design for, including the ones either side of the points where a layout changes, and the same screen at 400% zoom.
The list
One example from each group is shown. Press a group to see the rest of it, or search. Sizes are in CSS pixels (what a layout actually sees), so a phone that advertises 1179 × 2556 appears here as 393 × 852.

33 of these screens are measured on every single change; the rest in the full sweep before a release. Each device is one row here — its upright, sideways and zoomed sizes are the chips beside it, and every one of them is opened and measured separately.
The difference
| Responsive, as it is usually done | Veloċi | |
|---|---|---|
| How many screens are considered | Two or three width rules (“phone, tablet, desktop”) and the hope that everything between behaves. | Every screen on this page is a named size that gets opened and measured, including the sizes either side of the points where a layout changes. |
| What happens between the sizes | The layout stretches. Whatever lands between the rules is what the maths produced. | The in-between sizes are measured too, because that is where a column collapses or a bar lands on a word. |
| Foldables | Treated as “a phone” or “a tablet”, whichever the width resembles. | Folded and opened are different screens with different layouts, and both are measured. So is a cover screen only 260 pixels tall. |
| Zoom | Rarely checked. A page often breaks at 200% and few notice. | 125%, 150%, 200% and 400% are sizes like any other. At 400% a dialog stops floating anything and becomes one readable column. |
| When content does not fit | It scrolls, and you are left to find that out. | The screen says so: a cue while there is more, gone once you reach the end. |
| What you are told about it | “Optimised for all devices.” | This page: the list, what is checked, what was measured, and what we could not check. |
Responsive design is the foundation and we use it. The difference is what happens after the rules are written: whether anyone opens all 233 of these and looks. What that takes is on the standard page.
What we check
And what this is not. These are emulated viewports in a Chromium browser, driven by a harness that opens every screen and dialog at every size and writes down what it finds — not a rack of real handsets, and not Safari or Firefox. Where a device’s CSS size is worked out from its published pixel count rather than read from the device itself, the row says so.
This list is the one for Australia. As we open in more countries it will change with them: each country gets the screens its customers actually hold. The devices, photographs, typefaces and other names that appear in our work belong to other people — credits and the legal notice are here.

Partner programme
Every business finds Veloċi somewhere: an ad, a search, a friend. We'd rather pay the friend. The fees are our advertising budget, paid to the person who brought the customer instead of to Meta, Google or Bing: $30 to $150 a package, plus hosting and mailbox fees every year they stay. The customer pays the same price either way, every partner must say so wherever their link appears, and we never pay for a review.
