Size
Controls the overall size of the grid, measured in UV coordinates. The Length and Width is set to 1 (one) by default, because you typically want UVs to fit within the 0 to 1 range and this setting clearly shows the 0 to 1 range.
Sets the spacing between grid lines. Grid lines appear in increments based on the decimal value you specify. This setting affects where UVs snap if you use the Snap to Grid feature.
Sets the number of lines between each grid line. By default, subdivision lines do not show; you must turn on Subdivision Lines for them to appear.
