How to install picture frame molding corners?

Plan picture frame molding by measuring the wall, choosing a repeatable layout, and marking every line before installation. Start with the usable wall area, note openings and obstacles, and sketch the complete arrangement before selecting pieces. Compare the required length with the page calculator and current product table, then round quantities up only after the final layout is confirmed. The polystyrene molding profile is 2.5 cm, with 4 cm available by order, and standard sticks are 240 cm long. Dry-check the proportions on the wall so narrow leftover gaps or crowded corners can be corrected before installation.

Plan the layout

Measure the usable width and height, subtract doors, windows, outlets, and fixed furniture, then draw the full pattern. Keep repeated gaps consistent and check how the layout ends at both corners. A centered or intentionally aligned design usually reads more clearly than a layout that leaves one narrow remainder.

Check quantities

Add the lengths of every horizontal, vertical, or curved run in the approved layout. Use the calculator and current product table on the related page instead of estimating from room area alone. The polystyrene molding profile is 2.5 cm, with 4 cm available by order, and standard sticks are 240 cm long. Confirm the final cut plan before converting the total length into an order quantity.
