Standard walkers, like Two-Button Folding Walkers without Wheels, are usually between 25 and 29 inches in width. However, many walkers are narrower than the standard width, measuring between 17.5 and 24 inches. Also, there are standard walkers with a width between 34 and 40 inches. The standard walkers with narrower widths are generally suitable for young adults and fit through narrow doors. On the other hand, wider-based walkers are better for larger users. If you want more doorway clearance, shop for walkers with the two front wheels positioned on the inside of the walker.
