To capture a mobile-sized rendering in WebPageTest, enter the page URL, select a mobile or emulated-mobile browser/device configuration, run the test, then inspect its visual result, filmstrip, or video. The output reflects the selected emulation and test conditions; it is not simply a desktop screenshot cropped to phone proportions.

In the browser or device controls, select a mobile configuration. The current test interface lists Chrome on an emulated Motorola G (gen 4); advanced configuration also offers browser, location, and device choices. Labels and available choices can change, so use the live interface rather than relying on a fixed sequence of clicks.

Set the test conditions relevant to your question: location, connection profile, number of runs, and first-view or repeat-view behavior. If you only need to see how a page is laid out at a mobile viewport, keep the other variables consistent with any comparison you plan to make.

What mobile emulation changes
WebPageTest’s mobile preset is an emulated Motorola G (gen 4), not a physical handset. A WebPageTest staff explanation says that mobile emulation changes the user-agent string, resizes the browser window to the selected device, and throttles CPU accordingly. The result is useful for examining an emulated mobile experience, but should not be described as a capture from a real phone.
The documented workflow does not require you to own a phone. The available sources do not establish the current inventory or regional availability of physical-device test agents, so do not assume that a particular physical handset or test location is available.

Make screenshot comparisons meaningful
When two captures differ, first check whether the test setup differed as well as the page. Keep the following settings aligned when the aim is to compare the site rather than test conditions:
-
Rendering: mobile browser/device preset and emulation behavior.
