Resize a Widget auf Samsung
Widgets on a Samsung home screen are not fixed in size. Most of them can be stretched or shrunk to show more or less content, and in some cases the font size scales along with the widget.
To resize a widget, first tap and hold it until it lifts slightly and resize handles appear along its edges. This is the same action used to move a widget, so hold it a moment longer if a menu pops up instead.
Tap and hold a Widget ➔ Drag the Borders to resize the Widget
Drag any of the border handles inward or outward. The widget snaps to the underlying grid of your home screen, so the available sizes depend on how many columns and rows your layout currently uses.
Some widgets only support specific size ratios, such as a small square or a wide rectangle, and skip everything in between. If dragging does nothing, the widget you placed does not support resizing at all, and the only options are to move it, remove it, or swap it for a different widget size offered when you first added it.
