An index card is a useful tool for writing down and organizing useful information about specific subjects. These cards come in several different sizes the most common being 3-by-5 inch and 5-by-7 inch and are printed on a 110-weight paper. While they are made of this heavier paper, a cheaper version can be made from lighter 20-weight, letter-sized copy paper. Size is key here though; on a normal 8-by-11 inch sheet of paper only two 5-by-7 index cards can be cut. However, if 3-by-5 cards are made, you can get four from each sheet.
Lay paper down so that the 8-inch side is parallel to your body. This is often referred to as the "portrait" layout.
Measure 3 inches across the top with the ruler and make a mark with the pencil. Then measure 3 inches across the bottom making a mark.Connect these marks by lining them up with the ruler and drawing a vertical line from the top of the paper to the bottom.
Measure across the top and bottom of the paper at 6 inches and connect the marks with a vertical line.
Turn the paper and measure down the 11-inch side of the paper at 5 inches and at 10 inches making a mark. Repeat this on the opposite side. Then connect these marks together in the same manner as previously.
Cut along the lines to create four individual index cards and two strips of scrap paper.
