Measure witdh of your map in current zoomlevel use
google.maps.geometry.spherical.computeDistanceBetween()andmap.getBounds()(see doku).If measured distance is wider when desired, divide it by two. If it’s smaller, multiply by two.
Do this until the calculated width gets smaller oder bigger than the target width and count how often you have to multiply or divide.
Add / subtact the number you’ve counted to your current zoomvalue to get your target zoomvalue.
Note: you can not fit your map to an exact width, because you’re limited to the fixed zoomlevels, so this is only an approximation.
