How to Cut a Jig for Vinyl Siding

When you need to cut vinyl siding, you usually measure and cut each piece individually. However, there's a better and easier way to cut siding. You can cut a jig instead of cutting every piece one by one. A jig is a template or frame for guiding your cutting tool. For vinyl siding, your jig can help you cut evenly the lengths of the siding. You can design a jig to cut any size of siding you want.

Learn to cut a jig for vinyl siding.
  1. Measure the width of the siding you are going to use for your home with a tape measure. Record the figure on a piece of paper. This will be the measurement you use when you cut the jig for your vinyl siding.

  2. Measure the width of your vinyl siding onto two pieces of plywood and mark it with a pencil. Then measure and make another mark two inches longer than the original measurement you marked. Cut the two pieces of wood along the second mark with a wood saw. You then have two strips that are two inches longer than width of your siding.

  3. Make a half-inch cut on the first mark, which is the original width of your siding. This will make a notch on the wood strip. Then cut parallel to the length of the wood strip. You then have an L-shaped piece that is two inches longer than your siding, but has a notch that is exactly the same width of your siding.

  4. Cut the third piece of wood in the shape of a triangle. Use the measurement of your siding as the length of two sides of the triangle.

  5. Lay the two wood strips you cut in Step 3 on top of the triangular piece of wood you cut in Step 4. Align the strips so they are flush with two sides of the triangle. Position the two strips so that the notch you cut extends past the end of the triangle. Attach the strips to the triangle using an electric nailer, nailing in a nail about two inches from each end of the wood strip.

  6. Use your jig to cut your siding. Place the jig along the edge of the vinyl siding. Align the notch to the end of the siding. Cut along the other side of the triangle jig with a utility knife, using the side of the triangle with the other wooden strip attached as your cutting guide.


  • Saws and utility knives are very sharp, so be careful when working with them.
