A Few Styles Of Portrait Frames

This is usually the size of the image and not essentially the paper e.g. a 5x7 from a photo lab will usually be 5x7, but one can print a 5x7 at home on 5.5x8 papers. Mat exact opening: This dimension is that of a hole cut in the mat. This allows the mat to partly cover the picture by ¼ inch on all sides and also helps to hold the image down. Mat external size: A mat used to raise an image in a frame will have an external size of exactly same size.

Frame size:

This one is trickier. In the case of a standard frame used to frame an image of a normal size, the frame might be referred to as a regular frame size (knowing the complete frame package contains the appropriate mat). A standard frame with no mat will always be a larger frame. If the frame size (not mat opening) is standard then it is referring to the inside dimension. However, the frame will be cut a little larger, typically 1/8 inches. That allows room for the glass, rising board and mat to fit lacking fastening. It also permits for up to 1/16 inch error on the mat and glass dimension, as well as for extension and reduction due to temperature changes.

Outside frame size: This dimension is the extremely at the outside of the frame. It is rarely referred to except one is concerned about placing the frame in a inadequate space.

Rabbet depth:

This dimension tells how much room is there inside the frame for mat board, glass, and mount board. Some frame moldings are not deep enough to permit a dual mat to fit. Whatever be the dimensions, it is always important to see what fits best in the kind of place one wants to display a picture frame. Also it is important to bear in mind how easy it will be to manage the place if a particular dimension frame is presented.
