How to measure Neo-Angles

As you can see the typical door has 3/16" clearance on each side and 7/16" at the bottom. The door is 3/8" less than the opening width. There is one exception: Vienna Hinges require 1/4" on both sides..
It is better to get the door a little small than too big.

Measure the width at the top, the middle and the bottom. So long as the middle is not smaller than the top or bottom you can forget about it. The very bottom of the tile wall often curves in. Watch out for that. It is hard to measure accurately to inside corners because the tape has to bend. One trick is to make a mark on the tile and measure each direction from the mark, then add up the two dimensions. At the top, you can use a ruler or framing square. Hold the framing square in the opening and measure from the end of the framing square to the other side, add that together. This will give you a more accurate measurement than trying to bend the tape measure into the corner or holding the body of the tape in the corner.

The height can be anything you want; whatever looks good to you. 70" or 72" is common and we generally subtract the 7/16" clearance from that dimension so that the top lines up with the requested height.
If the difference in top and bottom is 1/16" we would consider making the door fit the smaller dimension. It is up too you.
If the difference is 1/8" or more, we would make the door out of square so that the sides line up with the tile.

If you make the door out of square you should find a square corner. If you pick the wrong corner then the bottom edge of the door will not line up with the tile. But this can also be corrected with a piece of sill vinyl. The way to find which corner is square is with a framing square and a straightedge, such as a four or six foot level, to even out the tile.
