, for a single cabinet I make the face frame flush with the outsides of the ends. For multiple cabinets (those that are next to each other, I have a method for installing face frames, making them flush to each other, and simplifies their installation.
When installing multiple cabinets, there's the tedious task of getting the face frames to line up flush. This is a tip that may be of some help. For example if you have three upper cabinets each having their own face frame call the first "A", the second "B", and the third "C". If you've installed the face frame on the cabinets, lay them on their backs and line them up so the face frames are as close to flush as possible. Start with "A" and "B". Clamp the two FF's together. From whichever side you are comfortable drilling and screwing, drill pilot holes and countersink in at least three places (top, middle, bottom) from one FF into the other. Make sure the holes are not drilled where hinges will be installed. Insert screws that will be shorter by 1/4" to 1/2" than the ones you will use when installing. Bump screws in tight. Remove clamps. Do the final scraping or sanding on the two FF's at once so they are flat and even. Then go to the "B" and "C" cabinets and do the same thing, etc.
When installing, after placing them where they are to go and leveling them, screw cabinets to the wall, but not up tight. Using the slightly longer screws, align the FF's, clamp, and insert screws into the same holes and bump tight. Then do the final tightening of the cabinets to the wall. If the wall is not flat,(how many are?) shimming the back of the cabinets may be necessary, so that there is no strain on the FF's. This method helps make final alignment easier.
