TL;DR
For most webbased speed tests it is no problem to use a browser zoom of 500%.
Of the top 10 speed tests, Ookla Speedtest and Meter.net offer a lesser user experience because they have a horizontal scrollbar at this magnification.

Introduction
For the visually impaired, being able to enlarge texts is often a dire necessity.
For this text we investigate to what extent speed tests are still useful when the magnification is maximum.
Method of measurement
For this test, only the magnification options of the browser are used.
Both Google Chrome, Microsoft Edge and Google Firefox support magnification up to 500%.
The test is performed with a maximized browser (F11), making the canvas 1920x1080 pixels in size.
We try to start the speed test and read the results. Note that, like most people, we are allergic for a horizontal scrollbar because it is bad usability.
Speed tests to test
Because this is a relative simple test, the unique speed tests as collected at ZOMDir will be tested.
