  Assuming you meant the composition is 1920x1080, and you wish to resize a layer to match the composition size, do one of the following:
  
  Right-click on the layer name. In the menu that comes up, click on Transform --> Fit to comp.
  
  Another method is, in the controls for Scale, under the Transform drilldown, right-click on one of the values. Click on `Edit Value`. Change units to `% of composition`. Alter the value of the larger dimension, out of Width and Height, to 100%.

  And because there's always  ~~two~~  another way of doing things in After Effects:
  
  * hit `shift``alt/option``ctrl/⌘``h` to Scale and reposition selected layers to fit composition width, preserving image aspect ratio for each layer
  * hit `shift``alt/option``ctrl/⌘``g` to Scale and reposition selected layers to fit composition height, preserving image aspect ratio for each layer.
  
  If the layer is the same aspect ratio as the comp both will have the same effect. Note that this will also centre the layer to the comp.
