;mute; GUIScale 5 is the basis of the calculations

Item size - can be changed
{itemsize=0.8}

Calculate how much we need to scale the item to make it fit a fixed a fixed width, height and position.
{itemscale=(itemsize/guiscale)*5}
%guiscale>=6, "{offset=0}", "{offset=0.5}"%

8 pixels

;hand, width/2-(itemscale*8)-offset, height/2+(itemscale/itemsize*guiscale)*2.9, itemscale,true;
