Guide

Wall molding is the strip of profiled trim fixed to a flat wall to create frames, panels, a chair rail line or a full accent wall. It adds shadow and depth to drywall without building out the wall, which is why it shows up in bedrooms, dining rooms, hallways and entryways. On this page you will find our pre-cut wall trim kits with real installation photos, the price of every kit, the profile and stick sizes we work with, and a calculator to estimate how much molding your wall needs before you order.

What our wall trim is made of

Our panel molding is a hard polystyrene polymer, not wood and not soft foam. It is light enough to hold with adhesive alone, it does not swell with humidity, and it can be sanded, caulked and painted like wood trim. Every piece arrives factory primed. Shaker, board and batten and arched designs use MDF instead, because those layouts need flat boards rather than a profiled strip.

Profile sizes and stick lengths

The standard panel molding profile is 2.5 cm, about 1 inch wide, which reads clearly on an 8 or 9 ft wall without looking heavy. A 4 cm profile is available made to order for taller walls. Straight stock comes in 240 cm sticks. Chair rail is offered in 4, 6 and 8 cm profiles, and the 6 cm chair rail comes in 300 cm lengths so a typical wall needs fewer joints.

Kits versus cutting trim yourself

Most wall trim projects fail at the cutting stage: miter angles that do not close, frames that end up different sizes, and offcuts that waste half a stick. Our kits arrive with every piece cut to length and mitered at 45 degrees, so the job on site is marking a level line, applying adhesive and painting. If your wall needs custom sizes, use the calculator on this page to get your frame count and total length first.

How much wall molding do you need

Multiply the number of frames by twice the sum of frame width and height, then add about 10 percent for waste. A 12 ft wall with three upper and three lower frames typically needs around 25 to 30 meters of 2.5 cm molding, or 11 to 13 sticks of 240 cm. The calculator and the layout tables on this page do this math for common wall widths.

Questions people ask

How do you trim walls?

Mark a level line for each frame, apply construction adhesive, joint compound or silicone dots to the back of each piece, press the pieces into place starting with the top rail, and tape them until the adhesive sets. Fill the miter joints, caulk the edges, sand lightly and paint the trim and wall together for a built-in look.

Is wall molding trendy?

Wall molding has moved from formal dining rooms into bedrooms, hallways and living rooms, usually painted the same color as the wall for a tone-on-tone look. Because it is architectural rather than decorative, it tends to age better than wallpaper or bold paint effects.

How is trim calculated?

For frames, add the width and height of one frame, multiply by two, multiply by the number of frames, then add 10 percent for waste. For a straight run like chair rail, measure the wall length and add 5 to 10 percent. Divide the total by the stick length, 240 cm for panel molding, and round up.
