maybe your width is too small?

[junior imp]

i mean that wouldnt make any sense tho, since length of the panel is 200

Prefer to set the preferredSize rather than the size. The entire point of a layout manager is to delegate sizing to it. For that it will try its best to honor preferred dimensions

BoxLayout honors the maximum size not the preferred size.

For a top-to-bottom box layout, the preferred width of the container is that of the maximum preferred width of the children. If the container is forced to be wider than that, BoxLayout attempts to size the width of each component to that of the container's width (minus insets). If the maximum size of a component is smaller than the width of the container, then X alignment comes into play.
see https://docs.oracle.com/javase/tutorial/uiswing/layout/box.html#:~:text=For a top,comes into play

Or If you want a stupid solution just add invisible/small characters to the buttons text

Im lazy i would probably do that

But i reccomend working with the layout manager
