We have shared a Porch Glider Plan in the past, but a variation on the theme is always in order. Everyone has a slightly different aesthetic and, even though the methods are essentially the same, seeing a design that suits your style is much more likely to get you to start building.
The following porch glider is a classic design that leaves much room for modification. Some simple lengthening, or shortening, of pieces will allow you to adjust the width to suit your exact needs. This free plan comes from The Handyman Club. This is a good website for any woodworker.
Good luck building your own porch glider.
