 bluephi191484 posts in 1535 days 09-20-2017 02:14 AM I am trying to figure out the formula for double doors for this particular opening . I am using the pictured hinges. Opening measurements are 19 7/16 wide – 26 5/8 tall the hinges are 1/2 inch overlay thanks in advance for any help. I know that there should be a 1/16 gap between the center of the doors, but im not sure how to calculate that. -- Jack of all trades and a master of most of them.

From that, subtract your center gap.

If you make the doors slightly wide, you can sneak up on the gap by taking light cuts with a jointer or hand plane and fit the gap. By doing it this way, you can correct for any minor errors in the sizes of the parts and mounting of the hinges that accumulated in the build. -- The optimist says "the glass is half full".

The bevels could also make short work of fine tuning with a hand plane after the doors are mounted to get the doors to close just right. A 5 degree bevel seems to work.
