often for small projects the binding is narrow- i would use the 1/4" seam & double fold unless directed to use single...it means you will have a 1/4" binding which is perfect for smaller projects- wider may take away from the over-all project---seem like a wide, border design element. i prefer narrow bindings & often use that size or 1 3/4"...i like them to just bind the quilt-not be part of the overall design.
