There are many ways to fix door hinge holes that strip out. This is a VERY common problem that I find on most of my rentals and on many of the houses I inspected as a home inspector. Here are a few ideas in order of robustness:

1) Toothpicks - If a hinge screw keeps turning because the wood frame is stripped, try this as a quick but short-term repair. Remove the screw, stuff a couple toothpicks into the hole (they will stick out some), and then put the screw back in and tighten LIGHTLY. Break off any remaining toothpick pieces. This is a quick repair but not always effective and likely won't last forever.

2) Epoxy - Remove the screw, mix up 5-minute 2-part epoxy and put in the hole...and BEFORE IT CURES insert the screw just until barely snug...holding inward pressure on the screw for about 3-4 minutes. This is a bit more robust of a repair, but will make the screw difficult to remove in the future.

3) Dowel - This is my FAVORITE method by far, is very robust, and not that difficult. Remove the screws (all of them on that hinge leaf) and rotate the leaf so you can see the frame or door. Buy some HARDWOOD dowel at big box store...Poplar works well and is cheap. Buy a size that is slightly larger than the hole..I think 1/4" works well in most cases. Use a 1/4" brad point drill bit (Brad point bits drill a much cleaner hole) and drill to the depth of the screw plus about 1/4". Cut a piece of dowel about 1/16" to 1/8" longer than the depth of the hole. Chamfer the end of the dowel slightly so it starts in the hole easily. Coat the dowel in any wood glue (Elmers is fine), and squirt some glue in the hole. Insert the dowel and lightly tap in with a hammer. Let dry for 1-2 hours. Use a flush cut saw blade (you can use a hacksaw blade in a pinch, but it's harder to do) to cut the dowel off flush with the door frame. Sand any slightly remaining proud areas. Fold the leaf back into place and mark the center of the hole with a pencil. Fold the leaf away and drill a tiny pilot hole for the screw (there are charts that will tell you the exact size to drill...see below link. Drill a brand new hole about 1/8" deeper than the length of the screw. Apply wax (an old candle works fine) as lubricant to the screw, and install the screw into the new hole. This is a very robust repair that will last a long time. I can do 3 holes in less than 10 minutes not counting the glue drying time. I have done hundreds of repairs this way.

Hoosier,

You are the expert here with door hinge holes so I will withdraw my suggestion of how I fill the hinge holes. I did not know golf tees were made of cedar but I don't play golf either.

Roy, golf tees are good for plugging vacuum lines on your car too.

I have product that are "Threaded Inserts for Wood" in assorted sizes. I remove the hinge drill out the hole so one of my inserts will fit tightly in the hole. I reinstall the hinge and use a special screw to attach the hinge to the wall insert.

I am with Scott----get a long screw and grab the stud. Only exception is an exterior door in a brick house. For that, I pry the trim off and hopefully there is enough clearance to slide in a piece of 3/4" plywood scrap between the door frame and the brick. On my last install, I put the plywood backer in there from the beginning and used longer screws on the top hinge.
