  1. 1

    Determine how the width of the blinds should be cut, and place a line with a pen to mark the spot. Cutting the blinds involves trimming the valance, head rail, bottom rail and slats with a hacksaw.

  2. 2

    Remove the metal piece, or the end stiffener, out of the head rail. Use the hacksaw to cut down the head rail on the mark that you made. Put the end stiffener in the head rail. Cut the bottom rail the same way.

  3. 3

    Mark with a pen on the valance where you need to cut it. Saw just beneath the line to make enough space for the metal brackets.

  4. 4

    Wrap a rubber band around the slats and make sure they lay evenly. Cut them with a hacksaw. Cover the slats in tape so that they are not damaged when you cut them. Trace a line on the tape where you need to trim them.

  5. 5

    Push the head rail and bottom rail into their original positions. Slide the valance back on the head rail. Place the blinds back on the window and check that the length is right.
