![]() ![]() I'll explain how to calculate them when we get to that point to avoid confusing things. The Frame dimensions are not needed right now. Comparing that to the PD shows that all four edges of the picture will be covered by the matting. In this case that comes out to 32" x 11 1/2". This will be the OD minus the two times the total matt width (36" - 2 1/4" x 2 wide by 16" - 2 1/4" x 2 high). MID: You only need to calculate this dimension to make sure that the matt border width you choose leaves an opening that is at least slightly smaller than PD so that the matt will cover the edges of the item being framed. Therefore rather than making another trip to the hobby store I decided I would make up the difference by allowing a slightly smaller visible border with 2" visible and 2 1/4" total matt width. Unfortunately the chip board I had available is not quite big enough at 36" x 16". In the example here that works out to 37 5/16" x 16". Therefore I need to add two times 2 1/4", or 4 1/2" to the width and the height of the PD to come up with the OD. There is a border on all sides of the picture. Therefore we need to add another quarter of an inch to the matt border for a total of 2 ". In the final picture frame, 1/4" of the matt will be covered all the way around by the wooden frame. I decided to have a 2" visible matt border. OD: To calculate this dimension you first need to decide how wide the visible matt border will be. In this case, the panorama print I'm framing in this example is exactly 32 13/16" x 12". To avoid any error caused by the end of the tape measure or ruler, I usually start the measurement at the first inch rather than the end. PD: To take this measurement, use a ruler or, if the thing to be framed is too big, use a tape measure. The inner dimension of the matt board will be slightly smaller than the picture's dimension so that the matt covers the edges of the picture. In the end, the glass, mounting board and the outside dimensions of the matt board will all be the same (OD). The object here is to generate the measurements for the mounting board, the matt and the glass. There is some room for error on a couple of them but most must be as accurate as possible. Make sure to be as accurate as possible when taking measurements. Miter box and hand saw (unless you have a very well calibrated power miter saw or table saw) ![]() cutter if you don't have it cut to size for you (highly recommended, particularly for glass). I will have alternate instructions if you choose not to get this tool. Mine cost $35 and it is more than made up for in the savings you will gain by doing your own custom framing. If you plan on making more than one frame over your lifetime, it is worth investing in this tool. I used the kitchen floor because my frame is too large to put together on a table or workbench.Īngled matt cutter. Tools: The following is a list of the tools needed to convert the materials listed above into a picture frame.Ī clean, flat workspace much larger than the frame under construction. Wood glue: You can use some wood glue to help reinforce the joints, but because it is an end to end joint, you will have to use joint fasteners. You can use the wood filler to fill the gaps, but if you plan in staining the frame, make sure to use wood filler that matches the stain or stainable wood filler. Wood filler: It is quite a challenge to create a perfect set of miter joints. For this tutorial I will be using spray paint. For this tutorial I'm using 1/2" by 2" poplar straight boards which will produce a very simple and elegant frame. A little longer is preferable to just the right size. Two of them must be at least FOD-width long and the other two FOD-height long. For this tutorial I chose lexan because the frame will be very large and lexan is a lot lighter than glass.Ĥ pieces of molding, picture frame boards (basically the same as molding except it already has a rabbet on the back side), or strait boards. For this tutorial I use a panorama print of a photograph I took on a trip to London in January of 2005.ġ piece of chip board at least OD in sizeġ piece of matt board at least OD in sizeĮnough acid free paper to cover an area at least PD in size, with a little left over (2"圆" or so)ġ piece of glass, plexiglass, lexan, or lucite at least OD in size. Materials: The following is a list of the materials we will make the frame out of.ġ photograph, print, drawing, document or some other flat piece of art to frame. MID: Matt Inside Dimensions - Width and height of the inside of the matt, always slightly smaller than PD. OD: Outside Dimensions - Width and height of the matt board and mounting board. PD: Picture Dimensions - Width and height of the thing to be framed. ![]() The next step has details on how to calculate each one. Measurements: There are a collection of dimensions that we will use throughout the tutorial.
