Terms of use

Wall Trim Lab provides estimates to help you plan decorative wall trim.

Check before buying or cutting

Results depend on your measurements and the stated assumptions. Rounded dimensions, material variation, wall conditions, cutting losses, and installation choices can affect the result. Check your plan against the actual wall and products before buying, cutting, or installing anything.

Planning assistance

The site does not provide a structural design, a professional installation specification, or advice about electrical work. Use manufacturer instructions and appropriate professional help where the task requires it. Do not rely on the diagram as a scale cutting template.

Obstacle comparisons

Comparisons only test trim overlap with one marked rectangle and the buffer you enter. They keep the other design settings fixed and do not exhaust every possible layout. A clear result is a two-dimensional geometry check, not a certification of installation safety or electrical clearance. Check any unmarked obstacles and the actual wall before using a cut list.

Responsibility

The tools are provided as an early planning aid, without a promise that every estimate will fit every project. You remain responsible for checking suitability and for how you carry out the work. Nothing in these terms excludes any liability or rights that applicable law does not allow to be excluded.

Website content

Original website content and code are reserved to their respective rights holders. You may use the calculators and print their results for your own projects. This notice does not claim ownership of general mathematical formulas, public facts, or third-party materials. Third-party software remains subject to its own licenses.
