Trench drains for patios and sidewalks are designed to prevent water from pooling in low spots. In the case of a sidewalk, water usually pools at the base of steps when the sidewalk is sloped toward the step, leaving no place for the water to drain. This is similar to what happens when a backyard patio slopes toward the house foundation: storm water has nowhere to go but to the junction between the patio and foundation wall. If there is a seam along that contact edge, water will most likely seep along the basement wall and damage the foundation.
By installing a trench drain along the base of the wall or step, you provide a conduit for the water to use that can be directed to a more suitable location other than your house.
Many trench drain options exist for this application, but the standard product uses a removable 4" to 6" grate. Because drains can be deceptively effective, you shouldn't need a wider drain for this application. Ultimately, you'll need to select how important aesthetics, economy, and material selection play in your drain selection.
