Guide

Picture frame molding, also called box molding or panel molding, is a series of rectangles made from thin trim and fixed directly to a wall. It is one of the easiest ways to add architectural character to a flat wall, and it works in almost any room. This page shows our picture frame molding kits with real installation photos, kit prices and options, the profile sizes we use, and a calculator to plan the size and number of your frames.

Choosing frame sizes

Most layouts use one row of tall upper frames and one row of shorter lower frames separated by a chair rail, or a single row of tall frames on walls without a rail. Keep the gaps between frames and the margins to the ceiling, floor and corners equal, usually 3 to 5 inches, and size the frames to the wall rather than the other way around. The layout tables on our room pages show worked examples.

The profile we use

Our frame molding is a 2.5 cm, about 1 inch, hard polystyrene profile. It is primed, sandable and paintable, and it is light enough to hold with adhesive. A 4 cm profile is made to order for tall walls or nested double frames. Straight molding comes in 240 cm sticks.

Single, nested and multi-tier frames

Single frames give a clean modern look. Nested frames add a second, smaller frame inside each panel for a more classic, French style finish, using the same 2.5 cm profile for both. Three-tier layouts add a middle row and suit tall walls and staircases. All three styles are available as pre-cut kits on this page.

Questions people ask

What is box molding?

Box molding is another name for picture frame molding: rectangles of thin trim attached to a wall to create the look of recessed panels. It is usually painted the same color as the wall and is often paired with a chair rail.

What is panel molding?

Panel molding is the narrow profiled trim used to form the frames on a wall or the panels in wainscoting. It is thinner than baseboard or chair rail. Our panel molding is a 2.5 cm polystyrene profile.

Is box molding timeless?

Box molding has been used in traditional interiors for centuries and is now common in modern homes as well, usually in one color with the wall. Because it adds structure rather than pattern, it holds up better over time than most decorative wall trends.
