This took me an embarrassingly long time to work out so I'll post it.
The problem I solved is self supporting a small picture frame on a tabletop or desk.
First I determined the angle. 17° is what my photo frame is set at, also my Google Home hub, and about what I had on other similarly placed desktop items.
I had this idea for a single foot as shown:
It can work in both the vertical and horizontal.
I decided a 3/16" dowel would be sufficiently strong for a small frame. At first I was going to go larger but it runs too close to the opening on narrow frames.
It has to be long enough... the center of mass of the frame has to be within the length of the foot or it will tip back too easily.
My frame was 8" x 5" rough dimensions and I wanted to make holes for both vertical and horizontal foot.
The frame leans back 2" when portrait mode... so the foot had to be at least 2".
Here's the dimensions I use to make the frame mounting hole:
3/16" brad point drill, 3/8" deep to the flat part. A drill press with a depth stop is recommended to set the depth.
The hole center should be 21/32" from the outside edge of the frame and centered in the width. Like I said I made two holes on adjacent sides to provide portrait and landscape modes.
The 3/16" dowel should be cut to 2.30 " or 2-5/16" if you prefer, long. I chamfer the end slightly to let it enter the frame hole more easily.
Usually a snug fit is achieved and I don't bother to glue the dowel in place, so it can be reassigned if you change the picture or decide to hang the frame.
If you have a larger frame you have to scale it... this is for a 4x6 print. A frame for a 8x10 would need about a four inch foot and you'd have to place the hole twice as far in requiring a sufficiently wide frame edge.
I love trigonometry.
