Standard Size Range
The standard length for PS decorative moldings is typically 2.4 or 2.5 meters per piece; this is the most common industry standard, facilitating both transportation and installation. The width (or decorative face height) typically ranges from 30 mm to 120 mm, while the thickness generally falls between 5 mm and 20 mm, depending on whether the molding features a hollow or solid internal structure.
Classification by Common Application
Smaller sizes (30–60 mm) are frequently used in spaces such as bedrooms and studies, offering a visually cleaner and lighter aesthetic. Medium sizes (60–90 mm) are suitable for standard areas-such as living rooms and hallways-striking a balance between decorative appeal and practical utility. Larger sizes (90–120 mm and above) are often employed in rooms with high ceilings, or in European-style and "light luxury" interior designs, serving to enhance three-dimensional depth and overall decorative impact.
Custom and Special Specifications
In addition to standard dimensions, some manufacturers offer custom specifications-including increased height, greater thickness, or unique cross-sectional profiles-to accommodate irregularly shaped spaces, feature walls, or specific requirements for stylistic consistency throughout a project. Furthermore, moldings featuring integrated mounting slots or concealed cable channels will typically have a slightly increased thickness to ensure full functional integrity.
