Measure the interior length and width of your drawer with a tape measure. Spread the liner out flat, front side down. Place a heavy object on the liner near where it is connected to the roll to keep the liner in place.
Mark the length and width measurements as the drawer on the backing of the liner. The backing of some liners provides cubic measurements that you can use for marking and cutting. If the backing does not provide lines, draw straight lines extending from the length and width markings, using a ruler.
Cut the length of the liner with scissors or a paper cutter along the lines on the backing, if provided. Cut the width of the liner along the lines on the backing, if provided. Remove 1 inch of the adhesive backing from the drawer liner at a time while pressing the liner in place inside the drawer to create a smooth surface.
