StackPanels stack, their contents only take up the space they ask for. The buttons only want to be as big as their content and the stackpanel is allowing that. (and is ignoring your HorizontalAlignment) If you want to stretch the buttons to the width of their container you will probably want to put them into a Grid which is happy to do stuff with the HorizontalAlignment.
You learn which containers behave in which ways eventually. (I still forget!) Each container handles the various attached properties in different ways.
