I am working on a touch screen on a small device and the custom width of the scroll-bar is no good as one of my requirements is that everything needs to be doable by finger gestures.
How can I set the width of the WPF ScrollViewer scrollbar?
Note that I don't wanna change the width of all the scrollbars on the device (doable through windows settings) - only the ones in my app.

Double-click/tap on ScrollHeight. The Edit String window will open with the default value of -255. That is the standard size of the scrollbars you see on Windows. To change the Scrollbars height to your liking, enter a value between -120 (smaller) to -1500 (larger) for the size you want, and click/tap on OK.
The scrollbar-width property is used to set the width or thickness of an element's scrollbar when shown. This property can be used on pages where the user interface requires the element to be displayed more prominently and shrinking the scrollbar width gives more space to the element.
The ScrollBar template reaches out for system parameters to determine its width/height (depending on orientation). Therefore, you can override those parameters:
<ScrollViewer> <ScrollViewer.Resources> <sys:Double x:Key="{x:Static SystemParameters.VerticalScrollBarWidthKey}">100</sys:Double> </ScrollViewer.Resources> </ScrollViewer> Kent's answer can also be applied to easily all scrollbars in your application by placing it in your App.xaml resources, and by specifying the horizontal height key as well.
<Application xmlns:sys="clr-namespace:System;assembly=mscorlib" ... > <Application.Resources> <sys:Double x:Key="{x:Static SystemParameters.VerticalScrollBarWidthKey}">50</sys:Double> <sys:Double x:Key="{x:Static SystemParameters.HorizontalScrollBarHeightKey}">50</sys:Double> </Application.Resources> </Application> If you love us?
