3 Hole Punching

3 hole punching is done for jobs that you may want to keep in a 3 ring binder. Problems can occur with these, however, if you have text and/or images that get drilled into. To keep your design elements from being drilled into, you need to know where the drilling will occur. The most used hole size is .25 inches, but there are others sizes as well, such as .375 or as small as .0625 inches. Unless specifically requested, all holes are drilled .25 inches from the edge of the sheet of paper. This allows you to figure out how much of a margin needs to be kept to allow for the drilling. If the job will have .25 inch holes, then you would want about a margin of about .625 inches (.25 for the hole, .25 from the dge of the sheet, and .125 from the edge of the hole to the start of the design). You can use these same calculations to figure out for other sizes as well, just change the hole size to what you are going to be using. At the bottom of the page are 2 files you can download and use as guides for the hole punching. One of them is for .25 inch holes, the other is for .3125 inch holes.
