Panel SizingFence PanelsWe offer multiple length panels, but they are all 30 inches tall. We do this because the standard fence/railing is about 36" tall. These panels are made to be installed with a beam on top and bottom, so we decided to give 6" of clearance so the fence/railing could still be the standard 36" with our panels installed.Stair RailingsOur stair railing panels follow standard sizing practices. The most common incline is 37 degrees, and the most common handrail is around 34 inches tall. We understand that not all staircases are built the same. If you need a different incline or hand rail height, please contact us for a quote!
