A door stile is one of the vertical sections on either side of the door panel, running from top to bottom. If you think of a door as a picture frame, the stiles are the side pieces on the left and right that support key components, such as locks, latches, and hinges.

In a framed glass door, the stiles provide structure and stability and define the look and function of the door. Door stiles are available in different widths, including narrow, medium, and wide stiles, each suited to different hardware and design needs. For example, a narrow stile creates a modern, minimal profile, commonly seen in office interiors, upscale storefronts, or contemporary glass entries. A wide stile offers a bolder frame and increased durability for high-traffic environments such as public buildings, schools, or commercial lobbies where additional strength and hardware compatibility are important.

The right door stile for a framed glass door depends on the design and hardware requirements, such as panic hardware compatibility, hinge size, and handle mounting space. Narrow stiles are best for sleek or modern designs and are commonly used in office buildings and storefronts such as boutiques and showrooms. Medium stiles work well with standard exit devices, such as panic bars or crash bars, because they offer sufficient surface area for secure mounting. Wide stiles are ideal for high-traffic areas, like hospitals and shopping malls, that require durability and support for larger handles or heavier locking systems. Overall, the top factors for choosing a framed door stile are traffic level, appearance, and hardware needs.

Framed and frameless glass doors differ in both construction and visual style. A framed glass door uses metal door stiles and rails around the edges of the glass. This frame provides added structural support, hardware compatibility, and a range of finish options. Framed doors are often chosen for commercial spaces, especially where durability, security, and code compliance are vital.

On the other hand, frameless glass doors use minimal or no visible framing, relying on thicker tempered glass and discreet hardware. They offer a sleek, seamless look and are often used in interior glass office partitions, high-end retail environments, or modern residential applications where design is a top priority. Both door types serve different functions, and the choice often comes down to the balance between aesthetics, durability, and hardware requirements.
