   Don't overthink the problem, it's easy to do. The inside edge of the frame sides simply equal the appropriate length of the newspaper plus if you want the news print to appear to float 2 times the desired open space. I would suggest somewhere around ½" open glass so the inside edge of the frame would be 1" longer than the newsprint.

   The glass itself would an additional ¾" in both directions to allow for a ⅜" deep dado to hold the glass in the frame

   If you know the depth of your groove, then you just do some adding and subtracting.

   For example:
   If your frame pieces are 3/4" thick and your groove is 1/8" deep. We will also pick a nice easy number for the glass (adjust accordingly, of course) - say 12 x 24.

   Then the interior of your frame piece will be 1/4" shorter than the piece of glass, or 23 3/4" for the long sides and 11 3/4 for the shorter sides.

   Since your corner angles will be 45 degrees, the total outside length will be 1 1/4" longer than the glass (remember the 1/8" groove). If we add 1 1/4" to our 23 3/4", we get 25" to the outside corners fo the long sides and 13" for the outside corners of the inside corners. However, to be honest, I'd add maybe a 1/16 or 3/32 to the total lengths to give a little breathing space for the glass.

   I think you will need to check your math, unless you meant to say the frame was ¾" wide, if so I would question that a frame only ¾" wide would be strong enough to hold ¼" of glass.

   I think the easiest way for the OP to understand this is to think of the inside frame measurement as at the minimum, equal to the dimensions of the newsprint they intend to frame. If they need to know the outside length it will be the inside length plus 2 x the frame width.

   Since you will need some type of biscuit, domino, dowel or Spline to strengthen the miter enough to hold the weight of the glass I suggest a minimum width of 2". Using that width the outside length of a frame member that measured 12" on the inside would be 14"

   I also don't feel an ⅛" dado is deep enough to secure the glass and suggest at least ¼“ but I would do ⅜" since glass isn't always cut precisely. The size of the glass should be be determined by the frame and not the other way around. If you cut the dado ⅜" deep the glass should be cut to the inside frame measurements plus 5/8" this leaves an ⅛" margin of error yet still assures the glass will be held securely.

   Lay the glass on some craft paper and trace the corners. Decide how deep you want the dados and mark them out. You can draw the rest of your frame and use it as a plan or just measure off the marks.

   Diagonal lines drawn on the panes will not give you 45 degree corners. You can make the frame to those lines, but the frame may wind up asymmetrical and very cool looking or very wrong looking depending on your eye.

   The interesting part is whether to build it around your newsprint or figure out a way to be able to open and close it for the install.
