Guide
Decorative Wall Panels: Installation Guide begins with the wall, not the catalog. Measure the usable area, identify doors, windows, outlets, switches, and furniture, then decide which lines should align. This guide connects paneling corner trim with a practical layout, the matched kit list, current price data, and the calculator already on the page. Review the treatment from the main entrance and across the longest sight line. The chosen style should use consistent spacing and repeatable proportions. Use the verified dimensions below to compare the design with the actual wall before ordering.
Plan the wall before choosing a kit
Draw the full wall elevation and mark every interruption before comparing decorative wall panels options. Decide whether the composition should center on the whole wall, a bed, a sofa, a dining table, or another fixed feature. Repeated openings should share a clear baseline and consistent gaps. Check both end conditions because a layout that looks balanced in the middle can still leave an awkward strip at one corner. Use removable tape or light pencil marks to preview the main lines at full scale. This step makes it easier to compare the matched kit list with the layout you actually need, instead of forcing the wall to fit a product photograph.
Use verified dimensions for quantities
Calculate each run from the approved drawing rather than multiplying the room area by a general allowance. Add the horizontal, vertical, and curved lengths separately, then use the page calculator to combine them. The polystyrene molding profile is 2.5 cm, with 4 cm available by order, and standard sticks are 240 cm long. Openings, returns, damaged cuts, and pattern changes can affect the final quantity, so confirm the cut plan before ordering. For chair rail projects, 6 cm profiles are also available in 300 cm lengths. Keep all measurements in one unit while planning, then compare the total with the available stick length. This produces a traceable estimate without inventing a universal waste percentage or a standard layout for every room.
Compare matched options and current prices
Use the product list on this page to compare only the options matched to the same wall treatment. The accompanying price table reflects the catalog data attached to the page, so use it for current figures instead of copying an old amount into a project plan. Compare the treatment type, listed dimensions, and the number of repeated elements required by your drawing. MDF is available only for shaker, board and batten, and arched designs. Other listed molding uses the 2.5 cm polystyrene profile, with 4 cm available by order. Confirm the final wall measurements and selected option together before treating the calculator result as an order quantity.
