How to Enlarge a Drawing Using a Grid
Step 1
Select the picture you want to enlarge.
Step 2
Place a ruler along the top edge of the picture.
Step 3
Make a small mark with a pencil at every 1/2 inch.
Step 4
Mark the bottom edge of the picture the same way. Make sure you have the same number of marks at the top and bottom of the picture.
Step 5
Connect each pencil mark at the top of the picture with a corresponding mark at the bottom using a ruler. This will make parallel lines over the picture.
Step 6
Measure and mark every 1/2 inch along the side edges of the picture.
Step 7
Connect the marks on each side. Your picture is now covered with squares called a grid.
Step 8
Calculate how much larger you need to make your picture and how large you need to make squares on a second grid. For example, if you are doubling the picture size, squares in the second grid will be 1 inch.
Step 9
Draw a second grid on a larger sheet of blank paper. Use a yardstick to make this larger grid if necessary.
Step 10
Copy the picture from the first grid, square by square, by drawing it on the new, larger grid.
Tip
Reduce a picture by decreasing the size of the squares on the second grid using the same technique. If the size of the original grid is 1/2 inch and you want to make the picture half the size, make 1/4-inch squares on the second grid. Use this technique to enlarge or copy cartoon characters, coloring book pictures and lettering for signs.
