I posted the same question {about the best way to cut the miters} about a week ago…might want to do a search. There was some very good advice and information that got posted in response. I do several picture frames a month it seems like. There are many ways to do it but will say these two things…first, it is very important that the wood you are using for the molding is perfectly straight, dead on size and square. If it is not then you will have gaps at the miters. Second, make sure you take into account sizes to allow for various matting you may have around the pictures.
Do that search and you will find it, very good thread to read thru for anyone interested in picture frames. Best of luck!!!

practice with cheap (true and square) 1×2 lumber before using the expensive stuff.
practice – practice – practice and practice some more.

I found this on Saw Mill Creek. I did not write it.

Hi,

I am making 3 picture frames out of walnut with maple inlay. Two will be the same size and one is a different size.
I ve got the inlay done and the rabbets cut and am ready to cut the frame down to size.

Whats the best way to cut the frame to the right size? I cut everything too long on purpose , how do I make sure I cut everything to the right size and that the picture fits? (preferably without complicated math).

Thanks in advance.

It’s really easy, no complicated math….just easy math.

Measure from the outside of the frame to the rabbet. (In my picture it’s 2”)
Measure your picture. ( my picture is 22 1/2”)
Decide how much play you want to give the picture, I’m going to make it 1/8” bigger than the picture.

So all you have to do is double the measurement from the outside of the frame to the rabbet,
that measurement is 2” so double it…4”
Now add 4” plus the amount you want to make it bigger by…1/8” = 4 1/8”
So the picture is 22 1/2…Plus the 4 1/8” = 26 5/8” This is the outside measurement for the frame.
(do the same thing for the opposite side)

Here’s my approach. No math or measuring required:
- Cut the rabbet.
- Cut a 45 on one end.
- Set the glass into the rabbet, with one side right up to the miter, and make a mark on the inside corner of the rabbet about 1/16” past the other side of the glass. Maybe a little farther, the glass doesn’t need to fit tightly.
- Use combo square to layout a 45 at the mark.
- Cut just past the line.
- Clamp a second board to the first, face to face. If using a sled, masking tape might be less cumbersome.
- Miter second board while clamped to the first.
Since the two boards were cut flush together on both ends while clamped, they are exactly the same length.
- Repeat with the other pair of sides.

deadherring,

“Woodsmith Shop” aired a program about picture frames which included a segment for building a table saw miter sled. Their sled seems to meet your requirements. The full episode and plans for the mitre sled come at a small price if the free preview is of interest.
