You can change the size of shapes in a layer to better highlight your geographic data points. Shapes that are too small can be easy to miss, while shapes that are too large can interfere with other shapes.
By default, shape size is set to 100%.
For the layer that you want to change, in the Layer Options area, use the Size slider to change the size of the shapes.
(If you don't see the Layer Pane, click Home > Layer Pane.)
If you want to make sure that your new settings don't get changed accidentally, select the Lock current scale check box.
